What is Contrave?

Contrave (naltrexone HCL/bupropion HCL) is a U.S. Food and Drug Administration (FDA)-approved prescription medication for weight loss.


In clinical studies, participants taking Contrave lost at least 5%, and sometimes up to 10%, of their body weight in 56 weeks. If you weigh 300 pounds, that’s a loss of 15 to 30 pounds! 

Contrave is meant to be used as part of a medical weight loss program that includes a reduced-calorie diet and increased physical activity. If you take Contrave as prescribed, it can help you lose weight and keep it off.

How does Contrave work for weight loss?

Contrave contains 2 active ingredients, bupropion and naltrexone. Bupropion is an FDA-approved antidepressant and the main ingredient in brand-name drug Wellbutrin. Naltrexone is an opioid antagonist FDA-approved to treat alcohol and opioid use disorders. Together, these active ingredients are thought to work in the brain to reduce your appetite and food intake while revving up your metabolism. The overall effect is weight loss. 

In clinical trials, people with obesity or overweight who took Contrave for weight loss lost 5% to 10% of their starting body weight over 56 weeks. 

Although Contrave contains active ingredients that are approved to treat depression and alcohol or opioid dependence, it isn’t approved or recommended for these conditions. Nor are Wellbutrin or naltrexone approved for weight loss. If you have these conditions, talk to a healthcare provider about a treatment plan specific to your symptoms.

Who’s eligible to take Contrave?

Contrave is FDA-approved for adults with a body mass index (BMI) of:

— 30 or greater (obesity)
— 27 or greater (overweight) with at least 1 weight-related health condition, such as type 2 diabetes, high blood pressure, or high cholesterol

When taking Contrave, it’s important to maintain a healthy diet and to exercise regularly. You shouldn’t take it if you have uncontrolled high blood pressure, seizure disorders, or are taking another medication containing bupropion or an opioid antagonist.

How to get a Contrave prescription online

To get Contrave — whether in-person or online — you need a prescription from a licensed healthcare provider who assesses you and determines it’s the right option for your needs. Providers who can prescribe medication, like Contrave, include physicians (MDs), nurse practitioners (NPs), and physician assistants/associates (PAs). If you want to find a provider who specializes in weight loss and weight management, look for a bariatric practitioner.

To get a Contrave prescription online, find a telehealth provider licensed to practice in your state. You can find one on Klarity Health and schedule an appointment in minutes. And, you can do it all online, or in person, whichever you prefer in states that don’t require at least one in-person visit, which some do.**

How to use Contrave and Contrave dosages

Contrave is a pill you take by mouth twice a day — once in the morning and again in the evening. It’s only available in 1 strength and form — 8 milligrams/90 milligrams tablets. Tablets should be taken whole (not chewed or crushed) and with a meal. Avoid high-fat meals to prevent side effects.

When starting Contrave, you take:

— 1 tablet in the morning each day for 1 week

— A second dose in the evenings during week 2

— 2 tablets in the morning and 1 in the evening during week 3

— A maintenance dose of 2 tablets in the morning and 2 tablets in the evening starting at week 4

Your provider will evaluate how you’re doing on the Contrave maintenance dose at 12 weeks. They may recommend stopping Contrave if you haven’t lost a certain amount of weight by this point. Talk to your provider about how to take Contrave and what to do if it doesn’t work for you.

Contrave side effects and warnings

The most common side effects of Contrave include nausea, vomiting, constipation, headache, dizziness, trouble sleeping, dry mouth, and diarrhea. These tend to go away as your body adjusts. If symptoms persist or interfere with your daily life, talk to your healthcare provider about how to manage Contrave’s side effects. 

Serious side effects have been reported with Contrave use and may require immediate medical attention. These include increased blood pressure or heart rate, seizures, tremor, manic episodes, allergic reactions, visual problems, and liver damage. Contrave may also increase your risk for low blood sugar (if you have type 2 diabetes), suicidal thoughts or actions, and opioid overdose or sudden opioid withdrawal.

Learn more about Contrave side effects, warnings, and precautions. Also talk to your healthcare provider or pharmacist.

And if you take Contrave and have negative side effects, consider reporting them to the FDA by visiting MedWatch or calling 1-800-FDA-1088.

What does Contrave cost?

A 1-month supply of Contrave (120 tablets) costs around $668, according to drugs.com and with its discount card. There isn’t a cheaper generic version available. 

You’ll likely pay less if you have insurance that covers it. Also, the manufacturer, Currax Pharmaceuticals, provides a few ways to save:

— With the Contrave Coupon Savings Card program, pay as little as $20 per month if you have insurance. Without insurance, you can use the savings card to cap your out-of-pocket cost at $199 per month. 
— Currax’s CurXAccess program offers Contrave for $99 or less and free shipping if you’re eligible and use Ridgway Mail Order Pharmacy to fill your prescriptions. 

Coupons from prescription discount sites can also help you save money, with or without insurance.

How does Contrave compare to other weight loss drugs

Contrave is about as effective as other popular weight loss pills, such as Qsymia (phentermine-topiramate) and Xenical (orlistat). In individual trials, participants taking either Contrave or Qsymia lost 5% to 10% of their starting body weight in 56 weeks. In trials for Xenical, people taking it lost at least 5% body weight in 1 year.

You’ll likely lose more weight if your provider recommends a weight loss injection. In trials for Wegovy (semaglutide), participants lost 14.9% body weight on average over 68 weeks. And in trials for Zepbound (tirzepatide), people lost more on it than Wegovy, Contrave, Saxenda (liraglutide), Qsymia, Adipex-P (phentermine), and Xenical. 


When comparing costs, you’ll pay less for Contrave than for prescription weight loss injections, which typically cost more than $1,000 per month without insurance. Contrave’s cost is in the middle-of-the-road compared to other weight loss pills though.  A 1-month supply of Qsymia costs about $211, while Xenical costs around $803 per month.

Saxenda, Qsymia, Adipex-P, Xenical, Zepbound, and Wegovy are all FDA-approved for weight loss or weight management in people with obesity and overweight when combined with a reduced-calorie diet and increased physical activity. All have side effects that may include, but aren’t limited to, nausea, vomiting, constipation, diarrhea, and headaches. Phentermine in Adipex-P is a controlled substance and can increase heart rate or blood pressure and cause dependency and misuse. Contrave is not a controlled substance even though it contains phentermine.

If you’re considering weight loss medication, consult your healthcare provider. They can help you determine which, if any, is right for you.
