THE SHORT ANSWER

Mounjaro is technically a dual GIP/GLP-1 receptor agonist, not a pure GLP-1 drug. It activates two different gut hormone receptors — GIP and GLP-1 — while drugs like Ozempic and Wegovy activate GLP-1 alone.

Per FDA prescribing information for tirzepatide (Mounjaro), Eli Lilly. Not medical advice.

How it's different

F—01

Two receptors

GIP and GLP-1 are both incretin hormones your gut releases after eating. Tirzepatide activates both; semaglutide activates GLP-1 only.

F—02

Why it matters

The added GIP activity is believed to contribute to the larger average A1C and weight reductions seen in head-to-head trial data against GLP-1-only drugs.

F—03

Same family, different tool

Mounjaro is still commonly grouped under the broader "GLP-1 drugs" umbrella in casual use — it's just not accurate at the molecular level.

Q & A

Is Mounjaro the same as Ozempic?Q—01 +
No. Ozempic's active ingredient is semaglutide, a GLP-1-only drug. Mounjaro's is tirzepatide, a dual GIP/GLP-1 drug. They're related but not the same molecule, and come from different manufacturers.
What is Mounjaro's generic name?Q—02 +
Tirzepatide. Mounjaro is the brand name Eli Lilly uses for the type-2-diabetes indication; the same molecule is sold as Zepbound for chronic weight management.
Who makes Mounjaro?Q—03 +
Eli Lilly and Company.
What drug class is Mounjaro?Q—04 +
A GIP/GLP-1 receptor agonist — sometimes called a "twincretin" or dual incretin agonist, since it activates two different gut hormone receptors rather than one.
What is Mounjaro used for?Q—05 +
Mounjaro is FDA-approved as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes. Its twin, Zepbound, is approved for chronic weight management.
