Approved uses

What is Mounjaro approved to treat?

Adults with type 2 diabetes, together with diet and exercise, to improve blood sugar.

Labeled maintenance: No named set — the label steps up in 2.5 mg increments while blood sugar needs more help, to a ceiling of 15 mg

Children age 10 and older with type 2 diabetes, together with diet and exercise.

Labeled maintenance: The same step pattern, stopping at 10 mg rather than 15 mg

Not an approved use: The Mounjaro label covers neither weight loss nor sleep apnea. Its trials measured weight change, but that is not what the label approves it for.
