Combining medications can lead to unexpected and potentially dangerous interactions, particularly when they affect the central nervous system, cardiovascular function, or metabolic processes. This is especially true for Contrave and codeine drug interactions, which pose significant health risks due to their opposing mechanisms of action.

Contrave, a prescription medication used for chronic weight management for compatible individuals, contains naltrexone and bupropion, both of which can impact neurotransmitter activity and opioid receptors. Codeine, an opioid analgesic, is commonly prescribed for pain relief and cough suppression, but it also has sedative effects and carries the potential for physical dependence and respiratory depression.

When taken together, these medications can interact in ways that may lead to serious adverse reactions, including an increased risk of seizures, precipitated opioid withdrawal symptoms, and elevated blood pressure. Understanding these interactions is crucial for patients and healthcare providers to prevent potentially life-threatening complications. So, is Contrave the right fit for your weight loss journey?

This article will explore the effects of Contrave and codeine drug interactions, detailing the risks, symptoms, and necessary precautions to ensure safe medication use.

Key Takeaways

Increased Risk of Seizures: Combining Contrave with codeine may elevate the risk of seizures due to bupropion’s effect on the seizure threshold.
Potential for Opioid Withdrawal: Naltrexone in Contrave can precipitate withdrawal symptoms in individuals dependent on opioids like codeine.
Elevated Blood Pressure: The combination may lead to increased blood pressure, necessitating careful monitoring.

What Is Contrave?

Contrave is a prescription medication combining two active ingredients: naltrexone and bupropion. It is primarily used for chronic weight management in certain adults with a body mass index (BMI) of 30 kg/m² or greater (obese) or 27 kg/m² or greater (overweight) with at least one weight-related condition, such as high blood pressure or type 2 diabetes.

Contrave is intended to be used alongside a reduced-calorie diet and increased physical activity.

Naltrexone: An opioid antagonist that blocks the effects of opioids in the brain.
Bupropion: A norepinephrine-dopamine reuptake inhibitor commonly used to treat depression and assist with smoking cessation.

Together, these components influence the central nervous system to reduce appetite and control cravings, aiding in weight loss efforts.

What Is Codeine?

Codeine is an opioid analgesic used to treat mild to moderately severe pain and to reduce coughing. It works by converting to morphine in the body, binding to opioid receptors in the brain to decrease the perception of pain and suppress cough reflexes.

As an opioid, codeine carries risks of physical dependence, respiratory depression, and potential for misuse. It is metabolized in the liver by the enzyme CYP2D6 into its active form, morphine.

Key Risks of Contrave and Codeine Interactions

Risk	Description
Seizures	Bupropion in Contrave lowers the seizure threshold, increasing seizure risk when combined with codeine.
Opioid Withdrawal	Naltrexone in Contrave blocks opioid receptors, triggering withdrawal symptoms in opioid-dependent individuals.
Elevated Blood Pressure	Both Contrave and codeine can raise blood pressure, posing a risk for individuals with hypertension.
Respiratory Depression	Codeine can slow breathing, and combining it with Contrave increases the risk of respiratory failure.
Allergic Reactions	Combining these drugs may increase the risk of allergic reactions, including rash, swelling, and breathing difficulties.

Dangers of Combining Contrave and Codeine

Using Contrave and codeine together can lead to several adverse reactions due to their pharmacological interactions:

Risk of Seizures

Bupropion, a component of Contrave, is known to lower the seizure threshold, increasing the likelihood of seizures. Combining bupropion with other drugs that also lower the seizure threshold or with substances that affect the central nervous system can further increase the risk of seizures.

Therefore, concurrent use of Contrave and codeine may elevate this risk.

Opioid Withdrawal Symptoms

Naltrexone in Contrave is an opioid antagonist that blocks opioid receptors. In individuals who regularly use opioids like codeine, naltrexone can precipitate opioid withdrawal symptoms.

These symptoms may occur rapidly and can be severe, including agitation, nausea, vomiting, sweating, and abdominal cramps.

Increased Blood Pressure

Contrave has been associated with increases in blood pressure and heart rate. Combining it with codeine, which can also affect cardiovascular function, may lead to further elevations in blood pressure. Additionally, Contrave and Metoprolol drug interactions can pose similar cardiovascular risks, particularly for individuals managing hypertension with beta-blockers.

This is particularly concerning for individuals with pre-existing high blood pressure or other cardiovascular conditions.

Symptoms of Interaction

When Contrave and codeine are taken together, several symptoms may manifest due to their pharmacological interactions. These symptoms can range from mild discomfort to severe, life-threatening conditions. Understanding these potential effects is crucial for patients taking bupropion and opioids, as some interactions may require immediate medical intervention.

Each symptom is outlined below in detail:

Seizures

The combination of bupropion in Contrave and codeine may significantly lower the seizure threshold, increasing the seizure risk.

Bupropion naltrexone is known to have pro-convulsant properties, which can increase the risk of seizures, especially in individuals with seizure disorders or other risk factors, such as a history of brain tumors or eating disorders.

Symptoms of seizures may include:

Convulsions or involuntary muscle contractions
Loss of consciousness
Sudden confusion or disorientation
Uncontrolled jerking movements
Aura (sensory disturbances before a seizure)

People taking other drugs that lower the seizure threshold, such as tricyclic antidepressants, may face an increased risk when using Contrave and codeine together.

Opioid Withdrawal Symptoms

Because naltrexone is an opioid antagonist, it blocks the effects of opioids like codeine. For individuals who have opioid dependence, Contrave can trigger opioid withdrawal symptoms, which may occur suddenly and may be severe.

Patients treated with opioids for chronic pain or opioid withdrawal management should avoid taking Contrave, as the combination can result in rapid and life-threatening withdrawal effects.

Symptoms of opioid withdrawal may include:

Extreme anxiety or restlessness
Muscle aches and joint pain
Profuse sweating and chills
Nausea, vomiting, or diarrhea
Abdominal cramps
Tremors or shaking
Rapid heart rate and high blood pressure

In severe cases, withdrawal symptoms can lead to cardiovascular complications, including severely high blood pressure or heart arrhythmias.

Elevated Blood Pressure

Both bupropion and naltrexone in Contrave have been linked to increased blood pressure, which can be further exacerbated by codeine’s effects on the cardiovascular system.

Patients with high blood pressure or those taking medications to regulate blood pressure should be especially cautious.

Signs of elevated blood pressure may include:

Persistent headaches
Dizziness or feeling lightheaded
Blurred vision
Shortness of breath
Nosebleeds
Chest pain in severe cases

A dosage adjustment or close monitoring of blood pressure may be required when taking naltrexone bupropion alongside other medications that impact cardiovascular function.

Respiratory Depression

Codeine is a central nervous system depressant that can slow down breathing. When combined with Contrave, especially in individuals with pre-existing respiratory conditions, there is an increased risk of severe respiratory depression, which may occur suddenly.

This risk is even higher for individuals taking other medications that suppress respiration, such as benzodiazepines.

Symptoms of respiratory depression may include:

Slow or shallow breathing
Difficulty breathing or gasping for air
Extreme drowsiness or unresponsiveness
Blue tint to lips or fingernails (cyanosis)
Confusion or mental fog

If respiratory depression progresses, it can lead to coma or even death, requiring immediate emergency medical attention.

Allergic Reactions

Taking Contrave and codeine together may increase the risk of an allergic reaction, especially in individuals with hypersensitivity to either medication.

A serious allergic reaction could lead to anaphylaxis, a life-threatening emergency that requires immediate medical intervention.

Symptoms of an allergic reaction may include:

Skin rash, redness, or itching
Swelling of the face, lips, or throat
Severe dizziness or fainting
Difficulty breathing or wheezing

Patients with a history of serious allergic reaction to bupropion, naltrexone, or opioids should not take Contrave and codeine together due to the heightened risk of anaphylaxis.

Understanding Contrave

What is Contrave?

Contrave is a combination drug designed to support weight loss treatment for compatible individuals struggling with obesity or a high body mass index (BMI). It contains two active ingredients: bupropion hydrochloride and naltrexone, both of which serve distinct roles in weight management.

Bupropion hydrochloride is commonly used as an antidepressant drug and is also prescribed for smoking cessation, while naltrexone is typically used to treat alcohol and opioid dependence. When combined, these two components help reduce food cravings and increase the likelihood of long-term weight loss success.

Contrave is intended for individuals who have been unable to lose weight through diet and exercise alone. To enhance its effectiveness, it is typically prescribed alongside a reduced-calorie diet and lifestyle interventions.

Healthcare professionals carefully assess a patient’s health history before prescribing this weight loss drug, as it carries risks related to blood pressure, mental health changes, and seizure disorders.

How Contrave Works

Contrave primarily influences the central nervous system to help regulate appetite and food cravings.

Bupropion hydrochloride, the initial active ingredient, elevates dopamine and norepinephrine levels in the brain. This action aids in treating depression, assists with smoking cessation, and diminishes hunger signals. The second active ingredient, naltrexone, acts as an opioid antagonist to curb cravings by preventing the brain’s reward system from reinforcing overeating behaviors.

By addressing both appetite suppression and food cravings, Contrave treatment aims to assist with long-term weight loss in individuals who struggle with emotional eating or binge eating tendencies.

However, because bupropion hydrochloride affects neurotransmitters in the brain, there is a risk of seizures, particularly in individuals with a history of seizure disorders, eating disorders, or those who have suddenly stopped drinking alcohol.

Contrave Interactions and Risks

Because Contrave contains bupropion hydrochloride, it has the potential to interact with a variety of other medications.

Patients should always tell their doctor about any other drugs they are taking to minimize potential drug interactions. Some of the key Contrave interactions and risks include:

Antidepressant drugs: Combining Contrave with SSRI antidepressants, tricyclic antidepressants, or monoamine oxidase inhibitors (MAOIs) may increase the risk of seizures, suicidal thoughts, and other mental health changes. Since bupropion hydrochloride is an antidepressant drug, and doctors often prescribe Contrave for depression, it can interact negatively with other medications in the same drug class.
Opioids (narcotic pain relievers): If taking both Contrave and tramadol, drug interactions can occur. The same is true of the drug interactions between Contrave and Codeine. Tramadol and codeine are opioid medications. This and other opioids should never be combined with Contrave unless under a healthcare provider’s guidance.
Blood pressure concerns: Contrave treatment can increase blood pressure, making it risky for individuals with high blood pressure or heart disease. Patients with a history of hypertension should be closely monitored when taking this medication. See our guide for a more detailed explanation of this and other symptoms and whether the side effects of Contrave go away.
Mental health effects: A boxed warning alerts doctors about the potential for suicidal thoughts and behaviors, particularly in young adults. Those with a history of mental health conditions should use Contrave treatment with caution.
Seizure risk: Bupropion hydrochloride is known to increase the risk of seizures, especially in individuals with a seizure disorder or those who are taking other drugs that affect the central nervous system.
Allergic reactions: Patients may experience allergic reactions, including rash, hives, dark urine, or difficulty breathing. If any of these symptoms occur, patients should seek immediate medical emergency assistance.
Abrupt discontinuation: Stopping Contrave treatment suddenly can lead to withdrawal symptoms, including mood swings, dizziness, and an increased risk of seizures. Patients should always follow a licensed healthcare professional’s guidance when adjusting their dosage.

Understanding Phentermine

What is Phentermine?

Phentermine is a weight loss drug classified as a stimulant. It is commonly prescribed for short-term weight loss treatment in certain individuals struggling with obesity or severe weight gain. Unlike Contrave, which combines two active ingredients, Phentermine is a single central nervous system stimulant that helps suppress appetite.

Because Phentermine is similar to amphetamine-based drugs, it is classified as a controlled substance in many regions due to its potential for abuse and dependence.

Healthcare providers typically prescribe it for no longer than 12 weeks, as long-term use may lead to adverse effects, including increased blood pressure, insomnia, and heart disease risks.

How Phentermine Works

Phentermine stimulates the central nervous system to increase norepinephrine levels. This helps suppress appetite by reducing hunger signals in the brain, making it easier for individuals to adhere to a reduced-calorie diet. Additionally, Phentermine can increase energy levels, which may help individuals engage in more physical activity to support their weight loss goals.

Although Phentermine is effective in promoting short-term weight loss for compatible individuals, it does not address food cravings like Contrave. Patients who struggle with emotional eating or binge eating disorder may not find Phentermine as effective as other weight loss drugs that specifically target food addiction behaviors.

Risks of Phentermine

While Phentermine is effective in reducing body weight, it is associated with various health risks that should be carefully considered before starting treatment.

Some of the key concerns include:

Blood pressure spikes: Phentermine can increase blood pressure, which is particularly concerning for individuals with high blood pressure or heart disease. To avoid adverse effects, patients should have their blood pressure monitored regularly while taking it.
Mental health concerns: Phentermine has been linked to an increased risk of suicidal thoughts and behaviors, particularly in individuals with a history of depression or other mental health changes. Combining Phentermine with antidepressant drugs or other medications affecting serotonin levels can lead to dangerous interactions.
Seizure risks: Because bupropion hydrochloride is present in Contrave, combining Phentermine with Contrave could increase the risk of seizures. Patients with seizure disorders or other neurological conditions should avoid taking these two weight-loss drugs together.
Allergic reactions: Some individuals taking Phentermine may experience allergic reactions, such as rashes, difficulty breathing, or dark urine. Any signs of an allergic reaction should be treated as a medical emergency.
Dependency and withdrawal risks: Since Phentermine is a stimulant, prolonged use may lead to dependency. Stopping the medication abruptly can lead to withdrawal symptoms, including fatigue, depression, and mood swings. Patients should follow a healthcare provider’s recommendations to gradually taper off Phentermine if needed.

By understanding the differences between Contrave and Phentermine, as well as their potential drug interactions, individuals can make informed decisions about their weight loss treatment.

Consulting a licensed healthcare professional before starting either medication is essential for ensuring safety and effectiveness.

Contrave and Phentermine Together: Drug Interactions

Taking Contrave and Phentermine together introduces potential drug interactions that may pose significant health risks. While both medications are prescribed for weight loss treatment, they function differently in the body.

Clinical trials have studied the interactions between Contrave and Phentermine, revealing findings such as average weight loss percentages and participant experiences. These findings underscore the importance of patient involvement in dietary and lifestyle changes during treatment.

Contrave treatment targets appetite suppression and food cravings through the combined action of bupropion hydrochloride and naltrexone, whereas Phentermine is a central nervous system stimulant that works primarily by reducing hunger signals.

Although each drug is effective on its own, taking them together can increase the risk of dangerous side effects, including high blood pressure, seizures, and mental health changes. For these reasons, healthcare professionals caution against using this drug combination unless closely monitored by a licensed healthcare professional.

Central Nervous System Effects

Both Contrave and Phentermine affect the central nervous system, which can result in severe neurological and psychiatric side effects. Bupropion hydrochloride, a component of Contrave, is classified as an antidepressant drug, meaning it alters neurotransmitter levels in the brain.

Phentermine, on the other hand, is a stimulant that increases dopamine and norepinephrine levels to suppress appetite. When taken together, these two drugs can create an overstimulated state in the brain, leading to serious complications, such as:

Seizure Disorders: Bupropion hydrochloride is known to increase the risk of seizures, particularly in patients with seizure disorders or those taking other medications that lower the seizure threshold. Since Phentermine also affects the central nervous system, the risk of a seizure disorder is heightened when these drugs are combined.
Mental Health Changes: Contrave treatment already comes with a boxed warning due to its link to suicidal thoughts and behaviors, particularly in young adults. The stimulant properties of Phentermine may exacerbate anxiety, depression, and mood instability, leading to dangerous mental health changes in susceptible individuals.
Suicidal Thoughts and Behaviors: Patients with a history of mental health conditions, including depression, bipolar disorder, or anxiety, should not take Contrave and Phentermine together. The increased risk of suicidal thoughts is a serious concern, and anyone experiencing mental health changes should tell their doctor immediately.

Because of these risks, individuals with a history of mental health disorders, seizure disorders, or substance abuse should avoid this drug combination altogether.

Blood Pressure Concerns

Taking Contrave and Phentermine together can increase blood pressure significantly. Both drugs affect cardiovascular function, which can be especially dangerous for individuals with pre-existing high blood pressure or heart disease.

Phentermine’s Effect on Blood Pressure: Phentermine is a stimulant, meaning it naturally increases blood pressure and heart rate. This makes it unsuitable for individuals with high blood pressure, hypertension, or cardiovascular disease.
Contrave’s Effect on Blood Pressure: Contrave treatment has also been linked to increased blood pressure, although the mechanism is different from that of Phentermine. Bupropion hydrochloride, a key component of Contrave, can increase blood pressure by altering neurotransmitter activity.
Compounded Cardiovascular Risks: When taken together, these two medications increase the risk of serious cardiovascular events, including stroke, heart attack, and arrhythmia. Healthcare professionals recommend that patients regularly monitor their blood pressure while taking either medication.

For individuals who already have high blood pressure or a family history of heart disease, this drug combination could pose life-threatening risks.

Patients should consult a licensed healthcare professional before starting Contrave treatment or Phentermine to assess whether their heart health can tolerate these medications.

Seizure Risks and Other Side Effects

The combination of Contrave and Phentermine presents an increased risk of seizures, particularly due to the bupropion hydrochloride component in Contrave.

Bupropion hydrochloride is known to lower the seizure threshold, meaning that individuals who are already prone to seizure disorders face a significantly higher risk when taking this medication.

Patients should be aware of the following high-risk factors that may contribute to seizures when using this drug combination:

Seizure Disorders: Individuals with a personal or family history of seizure disorders should not take Contrave treatment or Phentermine. The bupropion hydrochloride in Contrave directly affects neurotransmitter activity in the brain, which may trigger seizures even in those without a history of neurological disorders.
Anorexia Nervosa and Eating Disorders: Bupropion hydrochloride is contraindicated in individuals with anorexia nervosa or bulimia, as it can increase the risk of seizures due to electrolyte imbalances caused by disordered eating patterns. Since Phentermine is a stimulant weight loss drug, it may exacerbate disordered eating behaviors, leading to additional health complications.
Suddenly Stopped Drinking Alcohol: Patients who have recently suddenly stopped drinking alcohol are at a higher risk for seizures when taking bupropion hydrochloride. Alcohol withdrawal itself can trigger seizures, and combining it with Contrave or Phentermine may increase the risk of severe neurological side effects.
Other Medications That Lower Seizure Threshold: Certain antidepressant drugs, such as SSRI antidepressants, tricyclic antidepressants, and monoamine oxidase inhibitors, may interact negatively with Contrave treatment. When taken alongside Phentermine, these medications can increase the risk of seizures, especially in individuals with mental health disorders.

Increased Risk of Serotonin Syndrome

Serotonin syndrome is a potentially life-threatening condition that can occur when certain medications interact, leading to an excess of serotonin in the brain. This condition is particularly concerning when combining drugs that affect serotonin levels, such as selective serotonin reuptake inhibitors (SSRIs) and Contrave, which contains bupropion.

Serotonin syndrome symptoms include agitation, confusion, rapid heart rate, changes in blood pressure, and muscle rigidity. If you are taking Contrave and experience any of these symptoms, it is crucial to seek medical attention immediately. To minimize the risk of serotonin syndrome and other adverse effects, always inform your healthcare provider about all other medications you are taking.

Interaction with Selective Serotonin Reuptake Inhibitors (SSRIs)

Selective serotonin reuptake inhibitors (SSRIs) are a class of antidepressant drugs commonly prescribed to treat depression and anxiety disorders. Examples include fluoxetine (Prozac), sertraline (Zoloft), and paroxetine (Paxil). When taken with Contrave, which contains bupropion, SSRIs can increase the risk of serotonin syndrome, a serious condition caused by an excess of serotonin in the brain.

If you are taking an SSRI and Contrave, your doctor may need to adjust your dosage or monitor you closely for signs of serotonin syndrome. Symptoms to watch for include agitation, confusion, rapid heart rate, and changes in blood pressure. Always tell your doctor about all other medications you are taking to ensure safe and effective treatment.

Other Risks of Combining Contrave and Phentermine

In addition to the central nervous system effects, blood pressure concerns, and seizure risks, there are several other factors to consider when evaluating the safety of taking Contrave and Phentermine together:

Allergic Reactions: Some individuals may experience allergic reactions to either medication, including skin rashes, swelling, difficulty breathing, and dark urine. Severe reactions should be treated as a medical emergency.
Mental Health Changes: Combining these medications can lead to unexpected mood swings, agitation, and suicidal thoughts and behaviors. Patients with a history of mental health conditions should exercise extreme caution.
Urine Drug Test Complications: Since Phentermine is a stimulant, it may result in a false positive on a urine drug test, which could affect employment or legal situations. Patients should tell their doctor if they are required to take a urine drug test while using Phentermine.
Adverse Effects on Heart Health: The combined effects of increased blood pressure, heart rate changes, and cardiovascular strain may increase the risk of long-term heart disease.

Weight Gain After Stopping Weight Loss Drugs

Weight gain after stopping weight loss drugs is a common concern for many individuals. When you discontinue a weight loss drug, you may experience rebound weight gain, which can be both frustrating and demotivating. This rebound effect occurs because the body often returns to its previous state of metabolism and appetite regulation once the medication is stopped.

To manage weight gain after stopping a weight loss drug, it is essential to maintain a healthy lifestyle. This includes adhering to a balanced, reduced-calorie diet and engaging in regular physical activity. Consulting with a healthcare provider or a nutritionist can also provide personalized strategies to help maintain weight loss and prevent rebound weight gain. Remember, sustainable weight loss is a gradual process that involves long-term lifestyle changes.
