If you’ve been prescribed a GLP-1 medication — or you’re considering one — you’ve probably heard the names Ozempic, Wegovy, and Mounjaro thrown around interchangeably. But they’re not the same drug, they don’t work the same way, and they’re not approved for the same things. This guide breaks down exactly what makes each one different.
What Are GLP-1 Medications?
GLP-1 receptor agonists mimic a hormone your body produces after eating. They slow digestion, reduce appetite, and regulate blood sugar. Originally developed for type 2 diabetes, they became widely used for weight loss after clinical trials showed dramatic results.
Ozempic — The Diabetes Drug Everyone Knows
Ozempic (semaglutide) is FDA-approved for type 2 diabetes. It’s a weekly injection that lowers blood sugar with significant weight loss as a side effect. Not officially approved for weight loss — but frequently prescribed off-label for it. Doses go up to 2mg weekly.
Wegovy — Same Molecule, Different Purpose
Wegovy is also semaglutide — the exact same ingredient as Ozempic — but FDA-approved specifically for weight management. Doses are higher (up to 2.4mg weekly) and it’s prescribed to people with BMI over 30, or over 27 with a weight-related condition.
Mounjaro & Zepbound — The New Challenger
Mounjaro (tirzepatide) targets two hormones — GLP-1 and GIP — making it a dual agonist. Clinical trials showed greater average weight loss than semaglutide. Mounjaro is FDA-approved for diabetes; Zepbound is the same drug approved for weight loss.
Quick comparison:
- Ozempic — semaglutide, FDA-approved for type 2 diabetes, widely used off-label for weight loss
- Wegovy — semaglutide, FDA-approved for weight loss, higher dose (up to 2.4mg)
- Mounjaro — tirzepatide, FDA-approved for diabetes, targets both GLP-1 and GIP receptors
- Zepbound — tirzepatide, FDA-approved for weight loss
Which one should you choose?
That decision belongs to your doctor or telehealth provider. What we can tell you is that all three are effective, all three have side effects to manage, and access through telehealth has never been easier.
