01Dosage schedule
What’s the dosing schedule?
Mounjaro is taken once a week in the form of a “Mounjaro kwikpen” injection. The specific dosage and schedule will be determined based on individual needs and medical history. However, assuming no (or mild) side effects a fairly typical treatment plan could start as follows:
Weeks 1 – 4: 2.5mg (once a week)
Weeks 5 – 8: 5mg (once a week)
Weeks 9 – 12: 7.5mg (once a week)
Weeks 13 – 16: 10mg (once a week)
Please note that progression to stronger doses will be assessed individually and your clinician may increase your dose more slowly based on how well your body tolerates the medication.

Dosage changes should always be made in conjunction with your provider’s clinicians. Remember that slow, steady weight loss is the objective, and this approach will also minimise any side effects.
