Is pancreatitis a common side effect of Mounjaro?

Pancreatitis is not common, but it is a recognised serious risk listed in the warnings for GLP-1 medicines. Knowing the warning signs matters more than how often it happens. Check the Patient Information Leaflet and speak to your prescriber if you have concerns.

Should I stop Mounjaro because of pancreatitis?

Do not stop or change your treatment without speaking to your prescriber, unless you have symptoms that need urgent care, such as severe persistent stomach pain. Your prescriber may suggest staying on your current dose for longer, adjusting your dose or other measures. You can also report suspected side effects to the MHRA Yellow Card scheme.
