Mounjaro (tirzepatide) is administered once weekly. Treatment normally begins with a low dose and is gradually increased according to the prescribed dosing schedule.

What is the starting dose of Mounjaro?

The recommended starting dose is 2.5 mg once weekly for 4 weeks.

This dose is intended for treatment initiation and is not intended for glycemic control.

When is Mounjaro increased to 5 mg?

After four weeks at 2.5 mg, the recommended dosage increases to 5 mg once weekly.

The dose should not be increased faster than recommended unless specifically directed by a healthcare professional.

What Mounjaro doses are available?

Mounjaro is available in several dose strengths, including 2.5, 5, 7.5, 10, 12.5 and 15 mg.

If additional dose escalation is appropriate, the dosage can be increased in 2.5 mg increments after at least four weeks on the current dose.

What is the maximum Mounjaro dose?

The maximum recommended dosage for adults is 15 mg once weekly. Not everyone needs to reach the maximum dose.

Does a higher dose mean faster weight loss?

The dose should not be increased simply to try to lose weight faster. Dose selection depends on treatment response, medical goals and tolerability.

Increasing the dose too quickly may also increase gastrointestinal side effects such as nausea, vomiting and diarrhea.

Can someone remain on a lower dose?

A healthcare professional may decide not to increase the dose immediately depending on treatment response and side effects. The appropriate dose can therefore differ between patients.

Conclusion

Mounjaro generally starts at 2.5 mg once weekly for four weeks, followed by 5 mg weekly. Further increases can occur in 2.5 mg steps after at least four weeks on the current dose, with a maximum adult dosage of 15 mg weekly.

Medical notice: Do not increase or reduce your Mounjaro dose without instructions from your healthcare professional.
