Your doctor may increase your weekly dose further until it provides desired blood sugar levels. Additional increases in your weekly dose will be made at least 4 weeks apart.

The maximum Mounjaro dosage is 15 mg once per week.

Long-term treatment

Mounjaro is meant to be used as a long-term treatment. If you and your doctor determine that Mounjaro is safe and effective for you, you’ll likely take it long term.

The Mounjaro dosage your doctor prescribes will depend on several factors. These include:
