Stopping Mounjaro

Explain why you want or need to stop

The reason matters because the next step may be different. Tell your prescriber if the issue is affordability, supply, side effects, pregnancy plans or a feeling that treatment has not helped. If you use Mounjaro for diabetes too, ask specifically how blood sugar and other medicines will be managed.

You do not need to wait until your final pen to raise the subject. A short message such as ‘I cannot afford another month and need a plan’ gives the team something concrete to address. This guide does not provide a taper, missed-treatment schedule or instructions for restarting after a gap.

Prepare for appetite and weight to change

NICE advises that people who stop tirzepatide are likely to regain weight, while the longer-term pattern after stopping remains uncertain. That possibility is worth discussing before treatment ends. An increase in hunger or weight is information to bring to a review, not evidence that you have failed.

Choose a few routines that remain practical without treatment: a regular shopping plan, meals that fit your budget and enjoyable activity you can continue. Ask for dietetic or behavioural support if available. Agree how you will monitor changes without becoming consumed by them, and what would prompt you to get back in touch.

Leave with a written next-step plan

Ask for the date of your next review, who to contact and what to do if hunger, weight or a health condition becomes harder to manage. If pregnancy is the reason, ask for the medicine-specific stopping and contraception advice. If treatment ended because of a suspected serious reaction, make sure that is documented for future clinicians.

Restarting later needs a new clinical decision; do not use leftover pens or resume from memory. NICE advises that tirzepatide should not be restarted after confirmed pancreatitis. If you currently have severe, persistent abdominal pain, stop the medicine and seek urgent medical help rather than waiting to discuss routine stopping.
