Managing weight is a challenge for many people, especially those with obesity or related health conditions like type 2 diabetes, high blood pressure, or high cholesterol. Among the many treatment options available, Contrave and Saxenda have gained popularity as prescription weight loss medications. But how do they compare? In this blog, we’ll break down the differences between Contrave and Saxenda, including how they work, potential side effects, cost, and effectiveness—so you can make an informed decision.

Contrave is an FDA-approved prescription medication for chronic weight management in adults with a BMI of 30 or more, or 27 and above with at least one weight-related condition. It’s a combination of two drugs: bupropion (an antidepressant and smoking cessation aid) and naltrexone (used to manage alcohol and opioid dependence).
These two components work together to affect the hypothalamus (appetite control center) and the reward system in the brain. The result? A reduced appetite and lessened food cravings, helping users eat less and lose weight over time.
Saxenda, also FDA-approved for chronic weight management, contains liraglutide, a GLP-1 receptor agonist. Originally used to treat type 2 diabetes under the brand name Victoza, liraglutide regulates blood sugar and mimics an appetite-suppressing hormone that naturally occurs in the body.
Saxenda works by slowing gastric emptying, reducing hunger, and increasing feelings of fullness. It is administered via a once-daily injection.
