THE APPROVED USE

Mounjaro is FDA-approved as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes — the trial program supporting that approval showed A1C reductions of roughly 2.0% to 2.3% depending on dose.

Per FDA prescribing information for tirzepatide (Mounjaro) and the SURPASS clinical trial program, Eli Lilly. Not medical advice.

What the trials found

F—01

A1C reduction

In SURPASS-2, tirzepatide reduced A1C by 2.01% to 2.30% depending on dose over 40 weeks, all three doses outperforming semaglutide 1mg's 1.86%.

F—02

Weight loss as a secondary benefit

Trial participants with diabetes also saw meaningful weight loss, though typically less than in trials of people without diabetes.

F—03

Add-on to existing therapy

Trials studied tirzepatide added to metformin and other diabetes medications, not as a first-line standalone treatment for everyone.

Q & A

Is Mounjaro FDA-approved for type 2 diabetes?Q—01 +
Yes — it's Mounjaro's actual FDA-approved indication: an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes. Weight loss for people without diabetes is a separate indication under the brand name Zepbound.
How much does Mounjaro lower A1C?Q—02 +
In the SURPASS-2 trial, tirzepatide reduced A1C by 2.01% to 2.30% depending on dose over 40 weeks, versus 1.86% for semaglutide 1mg.
Is Mounjaro insulin?Q—03 +
No. Mounjaro is a GIP/GLP-1 receptor agonist, a different drug class from insulin. It can be used alongside insulin in some cases, but it isn't a form of insulin itself.
Can Mounjaro be used for type 1 diabetes?Q—04 +
No. Mounjaro is approved for type 2 diabetes only and has not been studied for use in type 1 diabetes.
Does Mounjaro replace metformin?Q—05 +
Not necessarily — in trials like SURPASS-2, tirzepatide was studied as an add-on to metformin, not a replacement. Whether to adjust other diabetes medications is a decision for your prescriber.
