Modafinil and Contrave Drug Interactions: Safety Guide
As more patients seek comprehensive approaches to improve focus, manage weight, and combat fatigue, the combination of medications like Contrave and modafinil is becoming increasingly common. However, this trend raises important safety concerns. The interaction between these two medications is not widely studied in clinical trials, making careful consideration and medical guidance essential for anyone considering or currently using both.
This guide examines the known and potential modafinil and Contrave drug interactions, highlights the increased risk of side effects, and provides guidance on monitoring, dosage adjustment, and risk factors.
Key Takeaways
- Combining Contrave and modafinil may increase the risk of seizures, serotonin syndrome, and elevated blood pressure. Monitoring is critical for patients on both medications.
- Contrave contains bupropion and naltrexone—two active compounds with unique effects on the brain’s reward system, which may intensify adverse reactions when combined with modafinil.
- Physicians must weigh the therapeutic benefits of this combination against potential complications, especially for patients with a history of psychiatric disorders, substance use, or cardiovascular conditions.
Understanding Contrave and Modafinil
Contrave is a fixed-dose combination medication composed of two active ingredients: bupropion and naltrexone. Together, they offer a unique dual mechanism of action aimed at addressing the neurochemical drivers behind overeating and cravings. Approved by the FDA for chronic weight management, Contrave is prescribed for certain adults with an initial body mass index (BMI) of 30 or higher, or 27 and above if the patient also has a weight-related condition such as diabetes mellitus, high cholesterol, or hypertension.
The first component, bupropion, is an atypical antidepressant most commonly used in treating major depressive disorder and smoking cessation. It works by inhibiting the reuptake of dopamine and norepinephrine—key neurotransmitters in the brain’s reward system. Through this action, bupropion can reduce the psychological urge to eat for comfort or reward.
The second ingredient, naltrexone hydrochloride, is an opioid receptor antagonist typically used to treat alcohol and opioid addiction. By blocking opioid receptors in the brain, naltrexone dampens the pleasure response associated with certain behaviors—like eating highly palatable foods. This makes it easier for compatible patients to resist cravings, particularly during the early phase of a reduced-calorie diet.
Together, bupropion naltrexone produces therapeutic effects that extend beyond simple appetite suppression. The combination aims to rebalance disrupted brain signaling related to reward and self-control, allowing for more sustainable weight loss among certain obese adults or those with weight-related comorbidities.
Modafinil, in contrast, is a wakefulness-promoting agent. It is FDA-approved for the treatment of excessive daytime sleepiness associated with narcolepsy, shift work sleep disorder, and obstructive sleep apnea. Unlike traditional stimulants, modafinil does not have a direct amphetamine-like mechanism. Instead, it enhances dopaminergic effects by inhibiting the dopamine transporter receptor, resulting in increased extracellular dopamine levels in key areas of the brain that govern alertness and attention.
Although not approved for this purpose, modafinil is sometimes used off-label to assist with weight loss due to its energy-boosting and appetite-suppressing effects. Some individuals report that it reduces the urge to snack or overeat, especially when combined with calorie restriction. However, this off-label use carries potential safety concerns—particularly when modafinil is used alongside medications that already affect the central nervous system, such as Contrave.
Both drugs target overlapping neural circuits, which is part of what raises red flags about modafinil and contrave drug interactions. Since they can influence reward, motivation, energy, and mood, their combined use may lead to amplified effects—or unintended complications.

Why Combining These Medications Raises Concerns
While there is only limited data on modafinil and Contrave drug interactions, their shared impact on the central nervous system warrants caution. Both bupropion and modafinil influence neurotransmitters like dopamine and norepinephrine, potentially increasing stimulation beyond a safe threshold.
According to Dr. Matthew Olesiak, Chief Medical Director at SANE MD,
“Combining stimulant-like medications can elevate the risk of seizures and increased blood pressure, particularly in individuals with underlying psychiatric disorders or cardiovascular issues.”
Additionally, bupropion inhibits the reuptake of dopamine and norepinephrine, and modafinil further enhances dopaminergic activity. This overlapping effect can raise systemic exposure and heighten the chance of serotonin syndrome, particularly when combined with other drugs affecting the serotonergic neurotransmitter system.
Increased Risk of Seizures
Among the most serious risks of combining these medications is the seizure threshold being lowered. Patients receiving bupropion, especially those with preexisting neurological conditions or electrolyte imbalances, are at higher risk. Modafinil may further compromise this threshold.
“Modafinil’s stimulation of the brain’s dopamine system may synergize with bupropion therapy in a way that reduces the seizure threshold significantly,” says Dr. Olesiak.
Cardiovascular Effects and Blood Pressure Monitoring
Both bupropion naltrexone and modafinil may cause increased blood pressure and chest pain, particularly in obese patients or those with congestive heart failure. Because Contrave can cause hypertensive reactions, and modafinil may also elevate blood pressure, patients must be monitored carefully for signs of cardiac strain. Sudden onset of joint pain, abdominal pain, or chest pain may occur and should be reported immediately.
A dosage adjustment or dose reduction may be needed if patients experience high blood pressure during treatment.
Impact on Mental Health
Patients with bipolar disorder, major depressive disorder, or obsessive-compulsive disorder should approach this combination with extreme caution. The stimulant effects of modafinil may exacerbate mood instability, while initiating bupropion therapy in such individuals has been associated with suicidal ideation and manic episodes.
Moreover, the combined use of these drugs may increase agitation, insomnia, and anxiety. These adverse reactions may occur in individuals without prior psychiatric diagnoses, especially if no dose adjustment is made over time.
Risk of Serotonin Syndrome
While serotonin syndrome is more commonly associated with the use of SSRIs, SNRIs, and monoamine oxidase inhibitors, it’s important to recognize that serotonin syndrome occurs when multiple medications—especially those that influence the serotonergic neurotransmitter system—lead to excess serotonin in the brain. This can happen even when the medications involved are not classified as traditional serotonergic drugs.
Both bupropion and modafinil have indirect effects on serotonin pathways. Bupropion inhibits the reuptake of norepinephrine and dopamine, and while it is not a primary serotonergic agent, it may still interact with other drugs that act on serotonin systems, raising the overall risk. Modafinil, though primarily known for its dopaminergic effects, has been shown to influence multiple neurotransmitters, including serotonin, especially when used alongside other drugs with serotonergic properties.
When these medications are combined—either with each other or with SSRIs, SNRIs, tricyclic antidepressants, or monoamine oxidase inhibitors—there is a theoretical and documented risk of serotonin syndrome, as demonstrated in Science Direct. Symptoms may include agitation, confusion, rapid heart rate, high blood pressure, tremor, muscle rigidity, and, in severe cases, seizures or respiratory depression. These reactions may occur rapidly and require immediate medical attention.
Because neither bupropion nor modafinil is traditionally flagged as a high-risk serotonergic agent, serotonin syndrome can be under-recognized in clinical settings. Healthcare providers should remain vigilant when prescribing these drugs in combination with other serotonergic agents or in patients with a history of psychiatric disorders, bipolar disorder, or obsessive-compulsive disorder, where polypharmacy is common.
Drug Interactions with Opiates, Alcohol, and Other Substances
Bupropion naltrexone is contraindicated with opiate agonists, such as morphine and codeine. Naltrexone, as an opioid antagonist, can precipitate opioid withdrawal symptoms, including respiratory depression, anxiety, and abdominal pain. This may occur even in individuals who are no longer actively using opioids but have residual dependency.
Opioid withdrawal or opioid addiction history must be ruled out before treatment initiation. This is especially important for patients being treated for alcohol and opioid addiction or undergoing nicotine replacement therapy, as bupropion inhibits the reward cycle reinforcement.
Likewise, alcohol dependence or active alcohol use may worsen adverse reactions, particularly joint pain, abdominal pain, and liver-related complications in those with severe hepatic impairment.
Common Side Effects and Adverse Reactions
When bupropion naltrexone and modafinil are taken together, the likelihood of experiencing adverse reactions increases due to their overlapping effects on the central nervous system and metabolism. While not everyone will experience problems, some symptoms are more commonly reported—especially during the early weeks of combined therapy or following a dosage adjustment.
The most frequently observed side effects in individuals using both medications include:
- Headache
- Nausea
- Abdominal pain
- Anxiety or restlessness
- Insomnia or disrupted sleep patterns
- Joint pain
These effects may occur independently or be amplified when the medications are used together. In many cases, they are mild and temporary—resolving as the body adapts to the medications. However, in some individuals, these reactions may occur persistently and require intervention. This could involve a dose reduction, a slower dosage increase, or even discontinuation of one of the drugs.
Importantly, some side effects—such as abdominal pain, joint pain, and chest pain—can mimic symptoms of more serious complications like cardiovascular events or hypertensive reactions. These should not be ignored and must be evaluated promptly by a healthcare provider.
In certain patients, side effects may emerge as part of broader psychiatric disorders, particularly if there’s a history of bipolar disorder, obsessive-compulsive disorder, or anxiety. These individuals may be more sensitive to changes in neurotransmitter levels caused by either drug.
At the biochemical level, the active metabolite of bupropion—known as hydroxybupropion—is largely responsible for the medication’s therapeutic and side-effect profiles. This metabolite is formed via the liver enzyme CYP2B6. However, modafinil is known to modulate cytochrome P450 activity, including CYP2B6, potentially interfering with the metabolic processing of bupropion, according to a study published on the NIH website.
This interference can lead to altered systemic exposure, resulting in statistically significant differences in the blood levels of bupropion and its metabolite. In real-world terms, this means that some patients may absorb too much of the active compounds, which could intensify side effects like high blood pressure, insomnia, or the risk of seizures.
Additionally, combining modafinil with other drugs that rely on the same metabolic enzymes—such as tricyclic antidepressants, antipsychotics, or systemic corticosteroids—could further complicate the body’s ability to safely process these substances. This increases the importance of reviewing all medications and supplements a patient is taking before starting combined therapy.
For those already on treatment, healthcare providers should monitor patients regularly for emerging symptoms and educate them on what to watch for—especially any signs of worsening abdominal pain, sustained anxiety, or chest pain. Early intervention can help prevent more serious complications and ensure the therapeutic effects of the treatment are not overshadowed by avoidable side effects.
Special Considerations for Dosing
Due to the increased risk of respiratory depression, abdominal pain, or seizure activity, gradual titration is essential. Physicians may recommend a slower dosage increase for Contrave when used with modafinil, especially in obese adults with body mass index thresholds above 30.
Also, taking Contrave with high-fat meals increases the rate of absorption, which may further complicate the interaction profile. A reduced-calorie diet is still recommended during contrave treatment, and patients should avoid fatty meals to minimize adverse reactions.
Smoking Cessation and Additional Therapeutic Use
Bupropion naltrexone is sometimes explored for smoking cessation, particularly for those with overlapping food cravings and nicotine dependence. Since modafinil also has off-label potential in attention and addiction disorders, the interaction profile may be complicated by therapeutic benefits across multiple domains, including neuropathic pain and attention-related issues.
Nevertheless, care must be taken not to assume enhanced efficacy simply because both medications affect mood, energy, or appetite. The combined therapeutic effects may be unpredictable and depend heavily on individual risk factors and metabolic rates.
Guidelines for Patients and Physicians
Patients considering or currently taking both Contrave and modafinil should:
- Disclose all current medications, including supplements and systemic corticosteroids or tricyclic antidepressants.
- Alert their doctor to any history of opioid addiction, alcohol dependence, or psychiatric disorders.
- Report side effects such as abdominal pain, joint pain, chest pain, or mood changes immediately.
- Understand that dose adjustment may be necessary at several stages of treatment.
- Avoid self-adjusting doses or substituting other drugs without physician oversight.
Frequently Asked Questions (FAQ)
Understanding how medications interact is essential for safety and treatment success.
Below are some of the most common questions about taking bupropion naltrexone (Contrave) and modafinil, as well as related drug combinations. Always consult your healthcare provider before starting or combining any medications.
1. Can you take modafinil and bupropion together?
Modafinil and bupropion may be taken together in some cases, but the combination should be approached with caution. Both drugs affect dopamine levels in the brain, which may increase the risk of seizures, especially in patients with a history of neurological conditions.
Additionally, modafinil may interfere with the metabolism of bupropion, potentially raising blood levels and the likelihood of adverse reactions. Doctors may recommend a dose adjustment or additional monitoring if these drugs are prescribed together.
2. What medications to avoid with Contrave?
Several medications should be avoided when taking Contrave due to potentially serious drug interactions. These include opiate agonists (such as codeine, hydrocodone, or morphine), as naltrexone may cause sudden opioid withdrawal symptoms. Monoamine oxidase inhibitors (MAOIs), used to treat depression, are also contraindicated, as combining them with bupropion therapy can lead to severe high blood pressure or serotonin syndrome. Other antidepressants can also cause adverse effects. Our recent article on taking Contrave and Paxil drug interactions explores this topic in depth.
Patients should also use caution with tricyclic antidepressants, antipsychotics, and other medications that lower the seizure threshold.
3. What drugs should not be taken with modafinil?
Medications that interact with the liver enzyme system—particularly CYP3A4 and CYP2B6—can be problematic when used with modafinil. This includes tricyclic antidepressants, hormonal contraceptives, and systemic corticosteroids, which may become less effective or increase the risk of side effects.
Additionally, modafinil can interfere with other drugs used to treat mental health conditions, increasing the risk of serotonin syndrome or cardiovascular effects. Patients with psychiatric disorders or those on complex regimens should be closely supervised if modafinil is introduced.
4. Can you take phentermine and Contrave at the same time?
Phentermine and Contrave are sometimes used together for weight loss, but this combination is not FDA-approved and carries certain risks. Both drugs can raise blood pressure and heart rate, increasing the chance of hypertensive reactions, chest pain, or abdominal pain in sensitive individuals.
There is also a concern about overstimulation of the central nervous system, which may heighten anxiety or the risk of seizures. If a physician considers combining them, they will likely recommend close monitoring and start with low doses to reduce potential harm.
Summary
Although combining modafinil and Contrave may seem appealing for patients aiming to lose weight while staying mentally alert, the combination introduces a web of possible drug interactions and side effects. The risk of seizures, increased blood pressure, serotonin syndrome, and opioid withdrawal symptoms makes it crucial for providers to monitor closely and educate patients thoroughly.
Physicians should review each patient’s history for opiate agonists, cardiovascular issues, and mental health conditions before initiating bupropion or adding modafinil. With tailored oversight, some patients may experience meaningful therapeutic effects, but safety must remain the top priority.

Taking Contrave and Nardil Together: Drug Interaction Guide
Combining prescription medications can be risky—especially when it involves drugs that affect brain chemistry. If you’re considering taking Contrave and Nardil together, it’s essential to understand how these medications might interact.
Both are powerful in their own right: Contrave is prescribed for weight loss for compatible individuals, while Nardil is a monoamine oxidase inhibitor (MAOI) used to treat depression. But taken together, they can increase the risk of side effects, including extremely high blood pressure, serious skin reactions, or even life-threatening events.
“Nardil is a very potent MAOI, and combining it with drugs like Contrave—particularly due to the bupropion component—can be dangerous without careful oversight,” explains Dr. Matthew Olesiak, Chief Medical Director at SANE MD. “This isn’t a casual combination—it requires clear justification and close monitoring by a qualified medical doctor.”
This guide breaks down the potential drug interactions, side effects to watch for, and why it’s crucial to talk with your doctor before combining these two medications.
Key Takeaways
- Combining Contrave and Nardil can cause serious or even life-threatening effects, including extremely high blood pressure, seizures, and allergic reaction symptoms.
- Contrave treatment is designed for certain individuals pursuing long-term weight management and should not be taken with MAOIs like Nardil without physician supervision.
- Always talk with your doctor about other medications you’re taking, especially if you’re being treated for mental disease, bipolar disorder, or eating disorders.
Understanding Contrave and Nardil
What Is Contrave?
Contrave is an FDA-approved prescription weight loss medication designed for long-term weight management in certain adults with a high body mass index (BMI), or those who are overweight with at least one weight-related condition like type 2 diabetes or high cholesterol.
It contains a combination of naltrexone and bupropion, two medications that affect different parts of the brain. Bupropion is a norepinephrine-dopamine reuptake inhibitor (NDRI) commonly used to treat depression and support smoking cessation, while naltrexone is an opioid antagonist used to reduce cravings in alcohol and opioid dependence.
Together, naltrexone and bupropion help regulate the brain’s reward system and hunger cues, making it easier for people to control food intake, resist emotional eating, and lose weight. Contrave is typically prescribed as part of a broader weight management strategy that includes a reduced-calorie diet, behavioral changes, and physical activity. However, these two medications can make Contrave drug interactions much more likely.
The medication is available in extended-release tablets to ensure consistent dosing throughout the day and minimize abrupt changes in blood concentration that could increase side effects.
What Is Nardil?
Nardil (phenelzine sulfate) is a monoamine oxidase inhibitor (MAOI) used to treat depression, particularly treatment-resistant or atypical forms that haven’t responded to SSRIs, SNRIs, or tricyclic antidepressants. MAOIs work by inhibiting the enzyme monoamine oxidase, which breaks down neurotransmitters like serotonin, dopamine, and norepinephrine. By blocking this enzyme, Nardil increases the levels of these neurotransmitters in the brain, improving mood and emotional stability.
However, MAOIs come with strict limitations due to their extensive and potentially dangerous drug interactions. They interact with numerous foods, over-the-counter medications, and other prescription drugs—especially those that also affect neurotransmitters.
These interactions can lead to severe complications, including extremely high blood pressure, serotonin syndrome, or hypertensive crisis, which is why careful oversight is required when prescribing or transitioning off an MAOI.
Why the Combination Is Risky
When you take naltrexone and bupropion together in Contrave, the bupropion component becomes a major concern if paired with MAOIs like Nardil. Both drugs influence dopamine and norepinephrine levels, and when combined, the resulting chemical overload can dangerously overstimulate the central nervous system.
The Most Serious Risks Include:
- Extremely high blood pressure: This can occur rapidly and may lead to stroke, heart attack, or other life-threatening cardiovascular events.
- Severe seizures: Bupropion already lowers the seizure threshold; pairing it with an MAOI further increases this risk, especially in patients with eating disorders, bipolar disorder, or a history of substance misuse.
- Sudden high body temperature: An early warning sign of serotonin syndrome or autonomic dysregulation.
- Pulse frequent urge changes: Fluctuations in heart rate or blood pressure may point to a developing crisis.
- Neck sweating vomiting rare symptoms: These may be part of a hypertensive reaction or early signs of neurological distress.
“There’s a boxed warning that alerts doctors about the increased risk of suicidal thoughts and behaviors when using naltrexone and bupropion in patients with mental disease or mood disorders,” says Dr. Matthew Olesiak. “Combining them with MAOIs further elevates that risk, particularly in vulnerable individuals.”
In addition to these serious risks, the combination of Contrave and Nardil may increase the risk of side effects such as:
- Discomfort, nausea, pain
- Serious skin reactions, including blistering or peeling
- Skin rash or hives
- Chest pain, agitation, or dizziness
- Low blood sugar or irregular blood sugar fluctuations in patients with diabetes
These effects are more likely in elderly patients or those with existing liver disease or kidney disease, where drug clearance is already compromised. Because both drugs are metabolized and excreted by these organs, toxic accumulation can occur quickly without close monitoring.
Potential Side Effects of Taking Contrave and Nardil Together
| Category | Possible Side Effects |
|---|---|
| Cardiovascular | High blood pressure, extremely high blood pressure, chest pain, rare chest pain, increased heart rate |
| Neurological | Severe seizures, severe spinning, nausea, headache, irritability, sudden or strong feelings |
| Psychiatric | Suicidal thoughts, mood changes, mental disease flare-ups, anxiety, agitation |
| Gastrointestinal | Discomfort, nausea, bowel symptoms, stomach pain, indigestion |
| Dermatological | Serious skin reactions, skin rash, severe acne, allergic reaction, skin reactions |
| Renal and Urinary | Common bladder pain, bloody, age-related kidney problems, end-stage kidney disease |
| Endocrine / Metabolic | Low blood sugar, fluctuations in blood sugar, weight changes |
| General / Systemic | Sudden high body temperature, neck sweating, vomiting rare, indigestion |
| Musculoskeletal | Sitting position muscle cramps, muscle tension, or weakness |
| Allergic / Immune Response | Allergic reaction, immediate medical attention required, accidental overdose |
Drug Interactions: What You Need to Know
MAOIs like Nardil are known to interact with a wide range of medications and substances, including naltrexone and bupropion, the two active ingredients in Contrave. This combination poses a serious risk due to overlapping mechanisms that affect neurotransmitters such as dopamine, norepinephrine, and serotonin.
What Can Happen When These Drugs Are Combined?
1. Increase blood pressure rapidly, sometimes to dangerous levels.
Combining bupropion with an MAOI can result in a hypertensive crisis—a sudden and extremely high blood pressure spike that may lead to stroke or cardiac complications. This occurs because both drugs elevate norepinephrine levels, which can overstimulate the cardiovascular system.
2. Trigger severe seizures.
Bupropion lowers the seizure threshold, particularly at higher doses or when combined with interacting drugs. When taken with an MAOI, this risk is amplified, especially in people with predisposing conditions like eating disorders, bipolar disorder, or a history of substance abuse.
3. Lead to suicidal thoughts or sudden or strong feelings.
The risk of suicidal thoughts is already heightened when taking naltrexone and bupropion, especially in young adults or people with mental illness. Adding an MAOI may intensify mood swings, emotional instability, or behavioral agitation.
4. Cause chest pain, agitation, or severe nausea.
People may experience a cluster of distressing symptoms such as rare chest pain, racing heart, dizziness, or severe nausea. These could indicate serotonin syndrome, autonomic instability, or other acute reactions that require immediate medical attention.
The U.S. Food and Drug Administration (FDA) provides specific guidelines regarding the interaction between monoamine oxidase inhibitors (MAOIs) and bupropion. According to the FDA, a minimum 14-day washout period should occur between discontinuing an MAOI intended to treat depression and starting therapy with bupropion. Conversely, at least 14 days should also elapse after stopping bupropion before initiating an MAOI. This washout period is necessary due to the increased risk of hypertensive reactions when bupropion is used concurrently with MAOIs.
“Even a single overlapping dose of Nardil and bupropion could lead to serious neurological or cardiovascular events,” warns Dr. Matthew Olesiak. “It’s not just about avoiding a bad reaction—it’s about preventing a true medical emergency.”
Side Effects to Watch For
Even if you’re not taking Contrave and Nardil together, being prescribed them close in time—or switching from one to the other—requires extra caution. These medications can cause overlapping or compounding side effects. Some may be mild at first, but others may signal a more serious issue developing under the surface.
Be Especially Alert For These Symptoms:
• Headache, irritability, and lack of energy
Often mistaken for fatigue or stress, these could be early signs of a reaction to naltrexone and bupropion, or signs your brain chemistry is being disrupted.
• Lips, stomach pain
This vague cluster can be a symptom of gastrointestinal upset, but when paired with skin flushing or chest pressure, it may indicate an early allergic reaction or autonomic issue.
• Allergic reaction (e.g., hives, swelling of the face, lips, or throat)
These reactions may seem minor at first but can escalate quickly into anaphylaxis. Seek immediate medical attention if you notice swelling, rashes, or trouble breathing.
• Bowel symptoms like nausea, vomiting, or diarrhea
Nausea is a common side effect of extended-release tablets, especially in the first weeks of starting Contrave treatment, but if paired with dizziness or frequent pulse issues, it may signal something more serious.
• Common bladder pain, bloody urine
Unusual urinary symptoms could point to an adverse renal reaction—especially in people with kidney disease or those taking high doses of naltrexone and bupropion.
• Chest pain or rare chest pain
Both medications can affect the heart. Any sensation of tightness, heaviness, or radiating pain in the chest should not be ignored, especially if you’re also feeling faint, dizzy, or nauseous.
If you experience any of the above, contact a medical professional immediately. These symptoms may indicate a severe risk of side effects, ranging from hypertensive crises to serotonin syndrome or even life-threatening reactions.
“No side effect should ever be dismissed as minor if it feels out of place for your body or your baseline,” notes Dr. Olesiak. “The key is to talk with your doctor early—before things escalate.”
Special Precautions
You should always talk with your doctor before starting Contrave treatment, stopping, or combining medications. This is critical to reduce the risk of side effects, particularly in individuals with preexisting health conditions or those taking other medications.
Here are some scenarios where increased risk is likely—and where extreme caution and medical oversight are required:
1. You Have Bipolar Disorder, Mental Disease, or a History of Suicidal Thoughts
People with mood disorders or mental disease, including bipolar disorder, are at greater risk for emotional instability and suicidal thoughts when taking naltrexone and bupropion.
These medications affect brain chemicals linked to mood regulation and can trigger sudden or strong feelings, mood swings, or even psychosis in sensitive individuals.
2. You Suffer from Liver Disease, Kidney Disease, or Age-Related Kidney Problems
Naltrexone and bupropion are metabolized by the liver and excreted through the kidneys. If you have liver disease, kidney disease, or age-related kidney problems, the drugs can build up in your system and lead to toxicity.
In these cases, your healthcare professional may need to adjust your dose or avoid Contrave altogether.
3. You Use Alcoholic Beverages or Drink Alcohol Regularly
Alcohol lowers the seizure threshold and may worsen side effects like dizziness, drowsiness, and nausea pain. It also increases the chances of experiencing accidental overdose or withdrawal-related symptoms if you’re taking naltrexone and bupropion to help reduce alcohol use.
“People with a history of alcohol abuse or dependency should be especially cautious,” says Dr. Matthew Olesiak. “Drink alcohol in moderation if at all, and never combine it with these medications unless cleared by your medical doctor.”
4. You Take Narcotic Drugs, Other Narcotic Medicine, or Other Habit-Forming Painkillers
Naltrexone is an opioid antagonist, meaning it blocks the effects of opioids. If you are taking narcotic drugs, other narcotic medicine, or other habit-forming painkillers, Contrave could cause sudden withdrawal symptoms or reduce the effectiveness of your pain medication.
You should never combine these without direct supervision by a healthcare professional.
5. You Have Eating Disorders Like Bulimia or Anorexia
Individuals with eating disorders often have electrolyte imbalances and a history of purging behaviors, which significantly increases the risk of severe seizures when taking bupropion, one of the active ingredients in Contrave.
This population is generally advised not to take Contrave due to the elevated seizure risk.
Drug Interactions to Watch For
Naltrexone and bupropion should not be taken with certain anxiety medicines (Xanax), antidepressant medications (Paxil, Lexapro, Effexor, Prozac, Cymbalta, Zoloft), over-the-counter sleep aids, or cold remedies containing stimulants (Ephedrine) or serotonin-affecting ingredients without the approval of your healthcare professional.
These combinations can lead to serious skin reactions, serotonin syndrome, or an increase in blood pressure.
Contrave Dosage and Safety Tips
Contrave comes as extended-release tablets, which are designed to maintain a steady release of naltrexone and bupropion in your system over time. According to the FDA-approved prescribing information, using these tablets as directed can reduce the risk of side effects and improve overall success in weight loss and weight management.
Here are key tips to ensure safe use:
Follow Your Doctor’s Instructions Carefully
Your medical doctor will start you on a gradually increasing dose to minimize side effects such as nausea pain, dizziness, or headaches. You should never adjust your dose on your own or take more than prescribed, even if you feel your progress has stalled.
“Many of the more severe issues we see stem from misuse,” warns Dr. Olesiak. “People often think more medication means faster weight loss, but it just increases the risk of complications.”
Never Take Double Doses If You Miss a Missed Dose
If you forget to take your dose, skip it and continue with your next scheduled one. Do not take double doses—taking extra to “make up” can trigger severe seizures, headache irritability lack, or confusion. Always follow your prescribed schedule.
Avoid High-Fat Meals
High fat meals can increase the absorption rate of bupropion, raising the chance of side effects like chest pain, discomfort nausea pain, or dizziness. Stick to a reduced calorie diet that supports your weight loss goals without compromising drug safety.
Sit or Stand Slowly
Some people may experience lightheadedness or muscle cramps in the sitting position when rising too quickly from sitting. This can be a result of fluctuating blood pressure, which is a known side effect of naltrexone and bupropion.
Should You Ever Take Contrave and Nardil Together?
In almost all cases, taking Contrave and Nardil together is not recommended due to the increased risk of life-threatening reactions. Most healthcare professionals will avoid prescribing them together unless absolutely necessary—and even then, only under tightly controlled conditions.
If you’re switching from one medication to another (e.g., stopping Nardil to begin starting Contrave treatment), you may need to wait 14–28 days, depending on your personal medical history.
Additional Safety Reminders
Even if you are following your prescribed dosage of Contrave, maintaining open communication with your healthcare team and staying vigilant about symptoms can help prevent serious complications.
Below are essential precautions to follow throughout your Contrave treatment, especially if you’re managing coexisting conditions or taking other medications.
1. Always Disclose Other Medicines or Other Medications You Take Regularly
Whether prescription, over the counter, or herbal supplements, every substance you take can potentially lead to certain drug interactions. Some may increase the risk of side effects, while others may reduce the effectiveness of naltrexone and bupropion.
Make a full list of all your other medications and share it with your healthcare professional at each appointment.
2. Notify Your Provider About Any Medical Tests You Have Scheduled
Both naltrexone and bupropion can interfere with lab test results, especially those measuring liver function or hormone levels.
Always talk with your doctor ahead of time if you have blood work, imaging, or any medical tests coming up, so they can advise you appropriately or adjust your treatment plan if needed.
3. Be Alert for Symptoms of Accidental Overdose
Taking too much Contrave—either intentionally or due to taking double doses after a missed dose—can lead to dangerous outcomes. Signs of an accidental overdose include tremors, severe seizures, confusion, blurred vision, and agitation.
These symptoms can escalate quickly and require immediate medical attention, so it’s vital to use the medication exactly as prescribed.
4. Don’t Mix Contrave with Narcotic Medicines Unless Your Medical Doctor Has Cleared It
Naltrexone, one of the active ingredients in Contrave, blocks the effects of opioids. If you’re taking narcotic medicines, narcotic drugs, or other narcotic medicines (codeine, methadone, morphine, fentanyl), combining them with Contrave could cause sudden withdrawal, intense pain, or a life-threatening reaction.
Your medical doctor must assess whether it’s safe for you to use Contrave in these circumstances.
5. Monitor Blood Sugar Closely, Especially if You Have Diabetes
Both naltrexone and bupropion can affect blood sugar regulation. You may experience episodes of low blood sugar, particularly if you’re on insulin or other glucose-lowering drugs. Keep a log of your blood sugar readings and report any unusual patterns to your healthcare professional.
Adjustments to your diabetes regimen or diet may be needed.
6. Report Any Skin Reactions or Severe Acne
Watch for signs of skin reactions, such as redness, blistering, rash, or severe acne. These could indicate an allergic reaction or even serious skin reactions that require stopping the medication.
If you notice any changes to your skin, no matter how minor, talk with your doctor right away.
7. Stay Hydrated and Monitor for Digestive Discomfort
Contrave may cause indigestion, nausea, or bloating, particularly during the early phases of treatment. Drinking enough water, eating smaller meals, and avoiding high-fat meals can help minimize symptoms like nausea, pain, stomach upset, or decreased appetite.
8. Use Contrave Only as Part of a Reduced Calorie Diet and Lifestyle Changes
Contrave is not a magic pill—it works best when combined with a reduced-calorie diet, increased physical activity, and healthy behavioral habits. If your goal is to lose weight or improve long-term weight management, following your full treatment plan is essential.
Taking Contrave without lifestyle changes may increase the risk of side effects without delivering the intended weight loss benefits.
Frequently Asked Questions (FAQ)
When it comes to prescription medications like Contrave and Nardil, understanding how they interact with other substances is key to staying safe.
Below are answers to some of the most common questions people ask about combining these drugs with other treatments, especially when managing weight loss, mood disorders, or chronic conditions.
1. What medications should not be taken with Contrave?
Several medications can interact dangerously with Contrave, especially those that affect the brain, liver, or blood pressure. Monoamine oxidase inhibitors (MAOIs) like Nardil must not be taken with Contrave due to the risk of extremely high blood pressure, severe seizures, and other life-threatening side effects.
In addition, narcotic drugs, other habit-forming painkillers, and drugs that lower the seizure threshold, like antipsychotics or certain anxiety medicines, can increase the risk of side effects. Over-the-counter products containing decongestants or stimulants may also raise blood pressure and should be avoided.
Always talk with your doctor before adding new medications while on Contrave.
2. What can you not take with Nardil?
Nardil is a powerful MAOI, and it comes with a long list of restricted substances. You should avoid all other antidepressants (especially SSRIs, SNRIs, and tricyclics), naltrexone and bupropion (found in Contrave), and any drugs that affect serotonin, dopamine, or norepinephrine.
Common cold medications, over-the-counter decongestants, and certain pain relievers like meperidine or tramadol can also cause serious skin reactions, serotonin syndrome, or dangerously high blood pressure. Even certain foods high in tyramine can trigger hypertensive episodes.
Because of these risks, it’s critical to talk with your doctor and review any other medications or supplements before using Nardil.
3. Can I take Contrave and Zoloft together?
Combining Contrave with Zoloft (sertraline), a selective serotonin reuptake inhibitor (SSRI), is not typically recommended without close medical supervision. Both medications influence brain neurotransmitters, and using them together may raise the risk of serotonin syndrome, severe seizures, and worsening mental disease symptoms like anxiety or suicidal thoughts. In some cases, a doctor may decide the benefits outweigh the risks, but this requires regular monitoring.
Be sure to talk with your doctor about any history of bipolar disorder, liver disease, or eating disorders, which may increase the likelihood of complications.
4. Can Contrave worsen depression?
Yes, Contrave can worsen symptoms of depression in some individuals, particularly those with a history of mood disorders or mental disease. The bupropion component is sometimes used to treat depression, but when combined with naltrexone, the emotional response can vary, especially during the initial weeks of treatment. There’s a boxed warning that alerts doctors about the possibility of suicidal thoughts, especially in young adults.
If you notice a change in mood, increased anxiety, or sudden or strong feelings, it’s important to talk with your doctor immediately. Monitoring and possible dosage adjustments can help reduce the risk of side effects.
Final Thoughts
The combination of Contrave and Nardil together can be dangerous without proper oversight. Given the potential for serious side effects, it’s crucial to talk with your doctor and follow up regularly.
“I advise patients to always keep an open line with their healthcare professional,” says Dr. Olesiak. “Even minor side effects can sometimes signal something bigger, especially with complex medications like naltrexone and bupropion or MAOIs.”
Always prioritize safety and long-term health outcomes over short-term weight loss goals. Remember, medications are tools—not substitutes for a broader weight management plan.

Taking Contrave and Rybelsus Together Drug Interactions
Combining medications for weight loss has become increasingly common, particularly as more people seek medically-supported strategies to manage body weight and improve metabolic health. Two such medications—Contrave and Rybelsus—are gaining attention for their potential effectiveness when taken together. But before combining these weight loss drugs, it’s essential to understand the possible drug interactions, side effects, and risks.
This guide explores what happens when you take Contrave and Rybelsus together, drug interactions, the science behind each medication, their approved uses, potential interactions, and important safety considerations.
Key Takeaways
- Contrave and Rybelsus target weight loss through different mechanisms, but combining them may increase the risk of low blood sugar, nausea, and other side effects.
- The combination may be effective for certain individuals, especially when used with a reduced-calorie diet and lifestyle changes, but only under close medical supervision.
- Your healthcare provider should evaluate your health history, current medications, and risk factors before prescribing both medications together.
Understanding Contrave and Rybelsus
Contrave is a combination medication that includes two active ingredients: naltrexone, which affects the brain’s reward system, and bupropion, which is commonly used to treat depression and aid smoking cessation. Together, they work on appetite and reward centers in the brain to reduce hunger and cravings.
Contrave is available as an extended-release tablet and is FDA approved for chronic weight management in certain adults with a BMI ≥30 or ≥27 and a weight-related condition such as type 2 diabetes or high blood pressure.
Rybelsus, on the other hand, contains the active ingredient semaglutide, a GLP-1 receptor agonist. It mimics a hormone that helps regulate blood sugar and slows gastric emptying, which can promote weight loss and improve blood sugar control.
Rybelsus is also an FDA-approved prescription medication used to manage type 2 diabetes and aid in weight loss in a subset of overweight or obese patients.
Can You Take Contrave and Rybelsus Together?
The combination of Contrave and Rybelsus is not explicitly contraindicated, but it’s not officially approved by the Food and Drug Administration (FDA) for use together, either.
However, doctors may prescribe both under certain conditions based on your health history and risk profile.
“Combining Contrave and Rybelsus may be effective for certain patients struggling with obesity or uncontrolled type 2 diabetes, but it must be approached with caution,” says Dr. Matthew Olesiak, MD, Chief Medical Director at SANE MD. “The potential for drug interactions and overlapping side effects—especially low blood sugar and nausea—requires close monitoring by a healthcare professional.”
This off-label combination targets different mechanisms: Contrave affects neurotransmitters in the brain, while Rybelsus enhances insulin production and slows digestion. For individuals with weight-related conditions, this dual approach may offer added benefit—but only when carefully monitored.
Potential Drug Interactions and Side Effects
Low Blood Sugar (Hypoglycemia)
One of the most notable concerns is the increased risk of low blood sugar, especially in people who take other diabetes medications or insulin. Both Rybelsus and other diabetes medications work to lower blood sugar, which can be compounded when taking additional weight loss medications.
Common symptoms of low blood sugar include dizziness, sweating, confusion, shakiness, and, in severe cases, loss of consciousness. Patients with a personal or family history of diabetes or hypoglycemia may be especially vulnerable.
Gastrointestinal Distress
When taking Contrave and Rybelsus together drug interactions can include nausea, vomiting, constipation, and diarrhea, particularly when first starting. These side effects may be intensified when combining Contrave and Rybelsus.
“Start low and go slow—titration is key when combining multiple weight loss drugs,” says Dr. Olesiak. “Most adverse effects occur early on, and careful adjustment can help patients tolerate the combination better.”
Increased Blood Pressure
Contrave, particularly the bupropion component, can increase blood pressure and heart rate. For individuals with high blood pressure or heart disease, this may raise the risk of serious cardiovascular events.
While some studies have indicated that bupropion may have a neutral or even cardioprotective effect, there is evidence suggesting that bupropion can lead to increases in blood pressure and heart rate, particularly at higher doses.
For instance, a study published in The American Journal of Psychiatry observed that bupropion caused a rise in supine blood pressure among depressed patients with heart disease, although it did not lead to significant conduction complications or exacerbate ventricular arrhythmias. Additionally, the FDA prescribing information for Contrave notes that patients may develop elevated blood pressure or heart rate during treatment, with the risk potentially being greater during the initial three months of therapy.
Therefore, monitoring blood pressure regularly and informing your healthcare provider of any history of heart disease or hypertension is critical.
Suicidal Thoughts and Mental Health
Contrave contains bupropion, which has a boxed warning for suicidal thoughts, especially in younger populations. Patients with a personal or family history of mental illness should proceed with caution and inform their healthcare provider of any mood changes.
Risk Factors to Consider
Before prescribing Contrave and Rybelsus together, a healthcare provider will carefully evaluate a patient’s medical conditions, health history, and current medication regimen. While this combination may be beneficial for certain individuals seeking weight loss, it can also increase the potential for serious adverse effects if not properly monitored.
Several specific factors may make the combination riskier for some people.
1. History of Seizure Disorders
Contrave contains bupropion, a prescription medication known to increase the risk of seizures, particularly in individuals with a personal or family history of seizure disorders. Taking Contrave in combination with other prescription drugs that lower the seizure threshold—such as Suboxone, or in high doses—can be dangerous.
People with conditions like epilepsy, severe head trauma, or those withdrawing from alcohol or sedatives should not take Contrave.
2. Thyroid Tumors or Family History of Medullary Thyroid Carcinoma
Rybelsus (semaglutide) carries a boxed warning for the potential development of thyroid tumors, including medullary thyroid carcinoma, based on findings from animal studies. Individuals with a personal or family history of this rare cancer—or those with multiple endocrine neoplasia syndrome type 2 (MEN 2)—should avoid taking Rybelsus.
Regular monitoring and clear communication about thyroid-related symptoms, such as neck swelling or difficulty swallowing, are essential during treatment.
3. Existing Liver Problems
Both Contrave and Rybelsus are metabolized through the liver. Individuals with moderate to severe liver problems may experience impaired drug clearance, which can lead to accumulation and increased risk of side effects.
Your doctor may adjust dosages or recommend alternative weight loss drugs depending on liver function tests and overall liver health.
4. History of Suicidal Thoughts or Mental Health Disorders
Because Contrave includes bupropion—an antidepressant—there is a most solemn warning regarding the risk of suicidal thoughts and behaviors, especially among young adults and those with mood disorders. Patients with a known personal or family history of depression, anxiety, or past suicide attempts should be closely monitored.
Any emerging mood changes, agitation, or worsening mental health should be reported immediately to a healthcare professional.
5. Current Use of Other Medications
Interactions with other drugs are a key concern when combining Contrave and Rybelsus. In particular, medications that affect dopamine levels (dopaminergic drugs), other diabetes medications, antidepressants, like Paxil, and medications that can increase blood pressure or heart rate, such as Vyvanse, may increase the risk of serious complications.
It’s critical to disclose all prescription medications, over-the-counter drugs, and supplements you’re taking.
6. Use of Other Diabetes Medications or Insulin
Rybelsus is often prescribed for blood sugar control in type 2 diabetes, and combining it with other diabetes medications or insulin can increase the risk of low blood sugar. Symptoms such as shakiness, confusion, dizziness, or fainting should be taken seriously.
A tailored treatment plan that includes close monitoring of blood sugar levels is crucial when using multiple diabetes medications together.
7. Previous Allergic Reactions to Any of the Active Ingredients
Patients who have experienced allergic reactions to semaglutide, bupropion, or naltrexone should not take Rybelsus or Contrave. Reactions can range from mild rash to serious, life-threatening conditions like anaphylaxis.
Symptoms of a severe allergic reaction may include hives, difficulty breathing, chest tightness, or swelling of the face or throat. These signs require immediate emergency medical attention—patients should stop the medication and call 911 or their local emergency services number right away.
Overall, before starting any combination of weight loss drugs, it’s essential to consider your health history, medical conditions, and any other medications you’re using. A shared decision-making process with your healthcare provider ensures your treatment is safe, effective, and aligned with your long-term goals for weight management and health improvement.
Weight Loss Benefits and Effectiveness
Although combining Contrave and Rybelsus is not officially recommended by the Food and Drug Administration, some doctors prescribe both when a single medication doesn’t deliver adequate results. This approach can be especially beneficial for individuals with a high starting body weight, obesity-related medical conditions, or those already using other diabetes medications.
The goal of this combination is to influence both appetite regulation and blood sugar control, leveraging different mechanisms to more effectively promote weight loss.
A 2024 retrospective cohort study published in the International Journal of Obesity found that adding bupropion/naltrexone to GLP-1 analogue therapy led to significantly greater weight loss, even among patients who were initially non-responsive to GLP-1 therapy alone (Naude et al., 2024).
Rybelsus helps regulate insulin secretion, delay gastric emptying, and curb appetite by acting on GLP-1 receptors, which supports both aiding weight loss and controlling blood glucose levels. Contrave, meanwhile, targets the brain’s reward system and hunger cues by combining two active ingredients—bupropion and naltrexone.
When taken together under supervision, they may offer complementary benefits: Rybelsus enhances satiety and blood sugar balance, while Contrave works to reduce cravings and emotional eating triggers.
Both medications have been proven in clinical trials to support significant weight loss, particularly when paired with a reduced-calorie diet, regular physical activity, and consistent lifestyle changes. For some individuals, this combination may result in more weight loss than using either medication alone, especially when previous efforts have failed to produce sustained results.
Clinical Trial Data
- In one pivotal trial published in the New England Journal of Medicine, semaglutide (Rybelsus) led to weight loss of up to 14% of participants’ body weight over a 68-week period. These outcomes were most notable in patients who adhered to treatment guidelines and engaged in lifestyle interventions.
- Contrave’s clinical trials demonstrated an average weight loss of approximately 4–5% over one year, particularly when used alongside structured behavioral support and nutritional counseling, as reported by FDA Access Data.
- For individuals with obesity or overweight with weight-related conditions such as high blood pressure or type 2 diabetes, these medications have also shown improvements in metabolic markers, including blood sugar, triglycerides, and waist circumference, according to the New England Journal of Medicine.
It’s important to note that individual results can vary. Factors like adherence to medication, dietary patterns, physical activity levels, medical conditions, other drugs in use, and starting body weight all influence how much weight loss a person may achieve. Some patients may lose a modest amount, while others could experience more dramatic changes over time.
In summary, although not officially approved to be taken in tandem, Contrave and Rybelsus may offer enhanced benefits for weight management when used cautiously together. However, this should only be considered after consultation with a qualified healthcare provider, and with close monitoring for side effects such as low blood sugar, increased blood pressure, or gastrointestinal discomfort.
When part of a comprehensive treatment plan, this combination may be a useful option for patients struggling with obesity or weight-related conditions who haven’t had success with a single agent alone.
