No. Wegovy is not tirzepatide. Wegovy contains semaglutide, while tirzepatide is the active ingredient in Zepbound and Mounjaro.
Last reviewed:
Semaglutide acts on the GLP-1 receptor. Tirzepatide acts on two receptors: GIP and GLP-1.
Wegovy vs. Tirzepatide
| Medication | Active ingredient | Main drug action | Common U.S. brand use |
|---|---|---|---|
| Wegovy | Semaglutide | GLP-1 receptor agonist | Chronic weight management |
| Zepbound | Tirzepatide | GIP and GLP-1 receptor agonist | Chronic weight management |
| Mounjaro | Tirzepatide | GIP and GLP-1 receptor agonist | Type 2 diabetes |
Wegovy and tirzepatide are different prescription medications. Both can reduce appetite and support weight loss, but they work through different hormone pathways. Semaglutide activates the GLP-1 receptor, while tirzepatide activates both the GIP and GLP-1 receptors.
Is Wegovy a GLP-1 Medication?
Yes. Wegovy is a GLP-1 receptor agonist. Its active ingredient, semaglutide, mimics the effects of the naturally occurring hormone GLP-1.
Tirzepatide is often grouped with GLP-1 medications because it activates the GLP-1 receptor. It is also a dual GIP/GLP-1 receptor agonist, so it is different from semaglutide.
Can You Take Wegovy and Tirzepatide Together?
Do not combine Wegovy with tirzepatide unless a qualified healthcare professional specifically tells you to do so. FDA prescribing information does not recommend combining Zepbound with another GLP-1 receptor agonist. Wegovy should not be used with other semaglutide-containing products or GLP-1 medications.
Wegovy and tirzepatide are not interchangeable on a milligram-for-milligram basis. If you are switching from Wegovy to Zepbound, or from tirzepatide to Wegovy, your prescriber should determine the timing and starting dose.
Bottom Line
If you are considering a switch, ask your prescriber which medication, timing and starting dose fit your treatment plan. Do not switch between Wegovy and tirzepatide or take them together without medical guidance.
