Frequently asked questions
How long do you stay on each tirzepatide dose?
Typically four weeks per step before considering an increase, though your clinician may move slower if you have side effects.
Do you have to reach 15 mg?
No. The right dose is the lowest one that controls appetite and maintains your results. Many people never go above 10 mg.
