Can you stop Mounjaro abruptly?

Yes, it’s possible to stop Mounjaro (tirzepatide) suddenly and this is not unsafe in itself. However, many UK clinicians advise planning a gradual dose reduction where possible to help appetite and weight changes stay manageable and to minimise discomfort. NICE guidance also sets clear points when stopping should be considered (for example, if less than 5% weight loss is achieved after 6 months on the highest tolerated dose), with the decision made together with a healthcare professional. If you do stop suddenly due to side effects or other reasons, be aware the medicine can remain in the body for several weeks, so effects may fade gradually rather than overnight. Before making changes, speak with a GP, prescribing pharmacist, or weight-management service for individual advice and a support plan.
