What Is Contrave?
Contrave is an FDA-approved oral weight management medication combining two drugs:
- Bupropion, often used to treat depression and support smoking cessation.
- Naltrexone, commonly used to manage alcohol or opioid dependence.
Together, these medications act on the hypothalamus and reward centers in the brain to help reduce food cravings and support appetite control.
Typical Use: Oral extended-release tablet, taken twice daily alongside lifestyle changes.
Common Side Effects:
- Nausea
- Headache
- Constipation
- Insomnia
Black Box Warning: Contrave includes a warning related to the risk of suicidal thoughts associated with bupropion, particularly in individuals with a history of depression or mood disorders. Providers may recommend psychiatric screening before prescribing (Christou & Kiortsis, 2015).
What Is Semaglutide?
Semaglutide is a GLP-1 receptor agonist that mimics a gut hormone involved in appetite and insulin regulation. It is the active ingredient in several FDA-approved medications, including::
- Ozempic (type 2 diabetes)
- Wegovy (chronic weight management)
- Rybelsus (oral tablet for type 2 diabetes)
In clinical studies and FDA-approved use, semaglutide has been shown to support metabolic health by:
- Reducing hunger signals
- Delaying stomach emptying
- Promoting a sense of fullness
- Supporting improved insulin sensitivity
Note: Semaglutide may help regulate appetite and promote healthier eating patterns when used as part of a provider-supervised plan.
Comparing Weight Outcomes
In a 68-week clinical trial using an FDA-approved dose of semaglutide (2.4 mg weekly), participants with overweight or obesity lost an average of 14.9% of their body weight under structured medical and lifestyle supervision (Wen et al., 2024). (Wen et al., 2024).
Clinical studies on Contrave showed average weight reductions between 4% and 8%, depending on adherence and baseline characteristics (Padwal, 2009).
These results were observed under trial conditions involving intensive lifestyle support. Real-world outcomes may vary and should be discussed with a provider.

Final Thoughts
Contrave and semaglutide are both FDA-approved options for weight management that work through different mechanisms and may be suited to different individuals. While semaglutide has been studied in trials with notable weight outcomes, Contrave may appeal to those who prefer an oral medication and are medically eligible.
The right approach depends on your health history, preferences, and provider guidance. Eden helps simplify the process by connecting you with licensed medical professionals who can evaluate your needs and determine whether a prescription is appropriate.
