Contrave vs Qsymia: Which Prescription Weight Loss Medication Is Right for You?
Weight loss medications have become vital tools in the fight against obesity, especially when diet and exercise alone aren’t enough. If you’re exploring prescription options, chances are you’ve come across Contrave and Qsymia. Both are FDA-approved drugs designed to help people lose weight, but they work differently and come with unique benefits and drawbacks. As someone who’s spent years researching weight loss treatments and tested various options for myself and my clients, I wanted to break down these two popular medications so you can make an informed choice.
Why Prescription Weight Loss Medications Matter
Here’s the thing: lifestyle changes are fundamental, but sometimes they’re not enough. According to a 2024 study by the National Institutes of Health, less than 20% of individuals with obesity achieve significant and sustained weight loss through lifestyle changes alone[1]. That’s why medications like Contrave and Qsymia can be game-changers—they offer an extra push when you need it most.
Understanding Contrave and Qsymia: The Basics
What is Contrave?
Contrave is a combination of two drugs: naltrexone and bupropion. Naltrexone is typically used to treat alcohol and opioid dependence, while bupropion is an antidepressant. Together, they work on the brain’s reward system to reduce food cravings and control appetite. Contrave was approved by the FDA in 2014 for chronic weight management in adults with a BMI of 30 or above, or 27 with at least one weight-related condition like hypertension or type 2 diabetes.
What is Qsymia?
Qsymia is an extended-release combination of phentermine and topiramate. Phentermine is a stimulant that suppresses appetite, while topiramate, originally an anticonvulsant, helps increase feelings of fullness and may reduce food cravings. Approved by the FDA in 2012, Qsymia is prescribed under similar criteria as Contrave but works in a slightly different way.
How Do They Work? A Closer Look
Both medications target the central nervous system but through different mechanisms.
- Contrave: Influences the hypothalamus and mesolimbic dopamine circuit, reducing hunger and controlling cravings.
- Qsymia: Combines appetite suppression with enhanced satiety by altering neurotransmitter activity.
In my experience, some patients find Contrave calming due to bupropion’s antidepressant effects, while others report Qsymia’s stimulant effects give them the energy boost needed to stick to exercise routines.
Comparing Effectiveness and Weight Loss Results
Clinical trials show both drugs are effective at helping patients lose weight over 12 to 56 weeks.
- Contrave users lose an average of 5-10% of their body weight[2].
- Qsymia users tend to lose between 8-12% in clinical studies[3].
That said, individual results vary widely. I’ve seen people respond better to one medication over the other. Some attribute this to how their bodies react to stimulants or mood-altering compounds.
Side Effects: What to Expect
Side effects are an important consideration, and both drugs have their own profiles.
- Contrave: Common side effects include nausea, headache, constipation, dizziness, and dry mouth. Because of bupropion, there’s also a risk of increased blood pressure and seizure, especially at higher doses.
- Qsymia: Patients often report tingling sensations, dry mouth, constipation, insomnia, and sometimes mood changes. Phentermine’s stimulant effect can cause jitteriness or increased heart rate.
From personal and professional observation, initial side effects tend to subside after a few weeks, but it’s crucial to monitor cardiovascular health closely when using either drug.
Pricing and Accessibility
Now, price can be a big factor when deciding which medication to try.
| Product | Active Ingredients | Average Weight Loss (%) | Common Side Effects | Price (Monthly) | Best For | Action |
|---|---|---|---|---|---|---|
| Contrave | Naltrexone + Bupropion | 5-10% | Nausea, headache, constipation | $250 – $300 | Craving control, mood support | Visit Official Site |
| Qsymia | Phentermine + Topiramate | 8-12% | Tingling, dry mouth, insomnia | $200 – $275 | Appetite suppression, energy boost | Check Latest Price |
| Semaglutide (Wegovy) | Semaglutide (GLP-1 receptor agonist) | 15-20% | Nausea, gastrointestinal discomfort | $1300 – $1500 | Significant weight loss, diabetes | Learn More |
It’s clear that both Contrave and Qsymia are in a similar price range, though more expensive than older weight loss meds but still less costly than newer drugs like semaglutide-based treatments. Insurance coverage varies, so it’s worth checking with your provider.
Pros and Cons
Contrave
- Pros: Helps control cravings, may support mood, fewer stimulant side effects.
- Cons: Risk of seizures at high doses, potential blood pressure increase, gastrointestinal upset.
Qsymia
- Pros: Strong appetite suppression, energy boost, effective for many patients.
- Cons: Possible insomnia, increased heart rate, tingling or numbness sensations.
Who Is This Best For?
If you struggle primarily with food cravings and emotional eating, Contrave might be your best bet. I’ve worked with clients who found it particularly helpful in breaking the cycle of constant snacking.
But if appetite suppression combined with a little extra energy suits your lifestyle, Qsymia could be a better fit. For example, I had a client who noted better workout adherence after starting Qsymia, likely due to its stimulating properties.
And in cases where more significant weight loss is required, semaglutide-based drugs, like Wegovy, have recently become popular, though they come with a higher price tag and different side effects — you can read more about those in our Wegovy vs Saxenda article.
Additional Considerations and Tips
Using prescription medications for weight loss should always be part of a broader strategy that includes diet, exercise, and behavior changes. I also recommend checking out our guides on managing side effects and sleep optimization, as these lifestyle factors dramatically influence outcomes.

FAQ
Which medication leads to more weight loss: Contrave or Qsymia?
Qsymia generally results in slightly greater average weight loss (8-12%) compared to Contrave (5-10%), but individual responses vary.
Are there any serious risks with these medications?
Both have risks including increased blood pressure and cardiovascular effects. Contrave carries a seizure risk, and Qsymia can increase heart rate. Close medical supervision is essential.
Can these medications be used long-term?
Yes, with physician guidance. The FDA approves both for long-term use in adults meeting weight and health criteria, though regular monitoring is needed.

Semaglutide drugs often yield greater weight loss (15-20%) but are more expensive and can come with gastrointestinal side effects. They work differently by mimicking GLP-1 hormones.
Final Thoughts
Choosing between Contrave and Qsymia isn’t a one-size-fits-all decision. Both have solid evidence backing their efficacy and safety, but your lifestyle, health profile, and personal preferences matter a lot. As someone who’s navigated these waters personally and professionally, I always suggest discussing options thoroughly with your healthcare provider, weighing benefits against risks.
