2. How Does Contrave Work in the Body?
Contrave’s mechanism of action is believed to involve the combined effects of its two active ingredients on areas of the brain that control appetite and energy expenditure.
- Naltrexone: This component is an opioid antagonist, primarily used to manage alcohol and opioid dependence. Its impact on weight loss is thought to be related to its effect on the reward pathways in the brain, potentially reducing cravings and overeating.
- Bupropion: This is an antidepressant that affects neurotransmitters in the brain, such as dopamine and norepinephrine. It may help reduce appetite and increase energy expenditure, contributing to weight loss.
Together, naltrexone and bupropion work synergistically to help individuals manage their weight more effectively when combined with lifestyle modifications.
3. What Are the Potential Benefits of Taking Contrave?
Taking Contrave, when combined with a reduced-calorie diet and increased physical activity, may offer several potential benefits for individuals struggling with weight management.
- Weight Loss: Clinical trials have demonstrated that Contrave can lead to significant weight loss compared to placebo when used in conjunction with lifestyle modifications.
- Improved Health Markers: Weight loss achieved with Contrave may result in improvements in various health markers, such as blood pressure, cholesterol levels, and blood sugar control.
- Reduced Risk of Weight-Related Complications: By helping individuals lose weight and maintain weight loss, Contrave may reduce the risk of developing weight-related complications such as type 2 diabetes, heart disease, and certain types of cancer.
- Enhanced Quality of Life: Successful weight management with Contrave can improve overall quality of life by boosting self-esteem, increasing energy levels, and enhancing physical function.
4. What Are the Potential Side Effects of Contrave?
Like all medications, Contrave can cause side effects. It’s essential to be aware of these potential effects before starting treatment.
- Common Side Effects:
- Nausea
- Constipation
- Headache

8. How Long Does It Take to See Results With Contrave?
The timeline for seeing results with Contrave can vary depending on individual factors such as adherence to diet and exercise recommendations, metabolism, and overall health status. Some individuals may start to see noticeable weight loss within the first few weeks of treatment, while others may take longer to respond.
In clinical trials, significant weight loss was observed after 12 to 24 weeks of treatment with Contrave. It’s important to have realistic expectations and continue taking Contrave as prescribed, along with lifestyle modifications, to achieve the best possible results.
9. Can Contrave Be Used With Other Weight Loss Medications?
The safety and effectiveness of using Contrave in combination with other weight loss medications have not been established. Therefore, it’s generally not recommended to use Contrave with other prescription, over-the-counter, or herbal weight loss products unless specifically directed by a healthcare provider.
Combining multiple weight loss medications can increase the risk of side effects and adverse interactions. It’s essential to discuss all medications and supplements you are taking with your healthcare provider before starting Contrave.
10. What Lifestyle Changes Should Be Made While Taking Contrave?
Contrave is most effective when used in conjunction with lifestyle modifications, including a reduced-calorie diet and increased physical activity. Key lifestyle changes to consider include:
- Reduced-Calorie Diet: Focus on consuming a balanced diet that is lower in calories than your usual intake. Prioritize whole, unprocessed foods such as fruits, vegetables, lean proteins, and whole grains.
- Regular Physical Activity: Aim for at least 150 minutes of moderate-intensity aerobic exercise per week, such as brisk walking, jogging, or swimming. Incorporate strength training exercises at least two days per week to build muscle mass and boost metabolism.
- Behavioral Strategies: Adopt behavioral strategies to support weight loss, such as keeping a food journal, planning meals in advance, and avoiding mindless eating.
- Adequate Sleep: Aim for 7-9 hours of quality sleep per night, as sleep deprivation can disrupt hormones that regulate appetite and metabolism.
- Stress Management: Practice stress-reducing techniques such as meditation, yoga, or deep breathing exercises to minimize stress-related eating.
11. How Does Contrave Compare to Other Weight Loss Medications?
Contrave is one of several FDA-approved weight loss medications available on the market. Other options include:

- Semaglutide (Wegovy): Similar to Liraglutide, Semaglutide is also an injectable GLP-1 receptor agonist.
Each of these medications has its own mechanism of action, potential benefits, and risks. The choice of which medication is most appropriate depends on individual factors such as medical history, preferences, and response to treatment.
12. What Happens If You Miss a Dose of Contrave?
If you miss a dose of Contrave, take it as soon as you remember, unless it is close to the time for your next scheduled dose. In that case, skip the missed dose and continue with your regular dosing schedule. Do not double up on doses to make up for a missed one.
If you frequently miss doses of Contrave, consider using a pill organizer or setting reminders to help you stay on track.
13. How Should Contrave Be Stored Properly?
Contrave should be stored in a safe place, out of reach of children and pets. Keep it in its original container, tightly closed, and protected from light and moisture. Store at room temperature, away from heat and humidity.
Do not store Contrave in the bathroom, as the humidity can damage the medication. Dispose of any unused or expired Contrave properly, following the instructions on the label or as directed by your pharmacist.
14. What Are the Long-Term Effects of Taking Contrave?
The long-term effects of taking Contrave are still being studied. However, clinical trials have shown that Contrave can be effective for weight loss and weight maintenance over a period of one year or longer.
Long-term use of Contrave may also result in sustained improvements in health markers such as blood pressure, cholesterol levels, and blood sugar control. However, it’s important to continue lifestyle modifications such as diet and exercise to maintain these benefits.
15. Can You Drink Alcohol While Taking Contrave?
Drinking alcohol while taking Contrave is generally not recommended. Both naltrexone and bupropion, the active ingredients in Contrave, can interact with alcohol and increase the risk of side effects such as nausea, dizziness, and drowsiness.
In addition, bupropion can lower the seizure threshold, and alcohol can further increase the risk of seizures. Combining Contrave with alcohol may also increase the risk of liver damage or other adverse effects.
16. What Are the Potential Drug Interactions With Contrave?
Contrave can interact with a variety of other medications, including:
- MAOIs: Contrave should not be used with MAOIs or within 14 days of stopping MAOIs due to the risk of serious and potentially fatal side effects.
- Opioids: Naltrexone, one of the ingredients in Contrave, can block the effects of opioids, including prescription pain medications and street drugs. This can lead to opioid withdrawal symptoms or a reduced response to pain relief.
- Other Bupropion-Containing Medications: Contrave should not be used with other medications containing bupropion, such as Wellbutrin or Zyban, as this can increase the risk of side effects such as seizures.
- CYP2B6 Inhibitors or Inducers: Medications that inhibit or induce the CYP2B6 enzyme can affect the metabolism of bupropion and alter its blood levels.
- Other Medications: Contrave can also interact with other medications, such as certain antidepressants, antipsychotics, and beta-blockers.
17. What Is the Cost of Contrave and Is It Covered by Insurance?
The cost of Contrave can vary depending on factors such as your insurance coverage, pharmacy, and location. Contrave is a prescription medication, so you will need a valid prescription from a healthcare provider to purchase it.
Some insurance plans may cover Contrave, while others may not. Check with your insurance provider to determine whether Contrave is covered under your plan and what your out-of-pocket costs will be. You may also be able to save money on Contrave by using a discount card or manufacturer coupon.
18. What Should You Do If You Suspect an Overdose of Contrave?
If you suspect an overdose of Contrave, seek immediate medical attention. Symptoms of a Contrave overdose may include seizures, hallucinations, loss of consciousness, and irregular heartbeat.
Call your local emergency number or go to the nearest hospital emergency room right away. Provide medical personnel with information about the medication you took, the dosage, and the time it was taken.
19. Is Contrave Safe for Elderly Individuals?
Contrave should be used with caution in elderly individuals, as they may be more susceptible to its side effects. Elderly individuals may be more likely to have age-related medical conditions or be taking other medications that can interact with Contrave.
Healthcare providers should carefully assess the risks and benefits of Contrave in elderly individuals and adjust the dosage accordingly. Regular monitoring of blood pressure, heart rate, and liver function may be necessary.
20. Can Contrave Cause Hair Loss?
Hair loss is not a common side effect of Contrave. However, some individuals may experience hair loss while taking Contrave, although this is rare.
If you experience hair loss while taking Contrave, talk to your healthcare provider. They may be able to determine the cause of the hair loss and recommend appropriate treatment.
21. What Is the Difference Between Contrave and Phentermine?
Contrave and phentermine are both prescription medications used for weight loss, but they have different mechanisms of action and potential side effects.
- Contrave: This medication combines naltrexone and bupropion to affect appetite and energy expenditure.
- Phentermine: This is a stimulant medication that suppresses appetite.
Phentermine is typically used for short-term weight loss, while Contrave is approved for long-term use. Phentermine may have a higher risk of cardiovascular side effects compared to Contrave.
22. Can Contrave Affect Your Mood or Cause Depression?
Contrave contains bupropion, which is an antidepressant. While bupropion can improve mood in some individuals, it can also cause or worsen depression or anxiety in others.
Some individuals taking Contrave may experience suicidal thoughts or actions, especially in the first few months of treatment or when the dosage is changed. It’s important to monitor your mood and behavior closely while taking Contrave and report any changes to your healthcare provider.
