Qsymia vs. Wegovy for Weight Loss: 6 Differences to Consider
Qsymia (phentermine / topiramate ER) and Wegovy (semaglutide) are both FDA-approved weight-loss medications. Wegovy requires a weekly injection under the skin, while Qsymia is an oral capsule taken once daily.
Wegovy may start working faster and result in more weight loss overall than Qsymia. But both medications have led to significant weight loss after 8 to 12 weeks in most people.
Both medications have different drug interactions and side effects to consider. Your healthcare team can review your medication list and personal history to help you decide which medication is best for you.
There are ways to save on Qsymia and Wegovy which are both only available as brand-name medications. If you’re eligible, manufacturer savings cards can help make your prescription more affordable. Patient assistance programs are also available.
