When Should You Stop Taking Mounjaro?

While your prescriber will always have the final word, a few scenarios come up repeatedly when people ask about pausing or stopping tirzepatide.

Before Surgery

Mounjaro slows gastric emptying — a well-documented effect of GLP-1-based medicines. During surgery that involves general anaesthesia or sedation, this can increase the risk of regurgitation and aspiration (stomach contents entering the airway), even if you have fasted in the usual way. Because of this, many anaesthetists and surgical teams ask patients to stop Mounjaro before a procedure.

How long to stop Mounjaro before surgery is something your surgical and anaesthetic team will specify based on the procedure and your individual circumstances. Guidance in various settings has referred to periods ranging from several days to a week or more, but the exact timeframe must come from your own clinical team — do not adjust or stop your dose without their instruction. If you have an upcoming procedure, raise Mounjaro specifically with your surgeon and anaesthetist well in advance so they can advise you clearly.

Before Pregnancy or When Trying to Conceive

If you are planning a pregnancy, the current advice in the prescribing information for tirzepatide recommends stopping the medicine before conception. The period recommended in the product information is typically referenced as at least one month before attempting to conceive — but always check the current leaflet that came with your pen and confirm the timing with your prescriber, as guidance can be updated. Mounjaro is not recommended during pregnancy, so this is a conversation to have with your doctor well before you start trying.

Other Circumstances

Some people consider stopping Mounjaro for other reasons — planned breaks, reaching a maintenance phase, or managing side effects. If you are thinking about pausing treatment for any reason, reading about taking a short break from Mounjaro and understanding how to approach stopping Mounjaro may be helpful background before you speak with your prescriber. There is also guidance on stopping Mounjaro gradually versus abruptly, which covers what to expect when treatment ends.

If you are approaching a planned stopping point — whether ahead of surgery, before trying to conceive, or for another reason — having a clear record of your treatment history can be genuinely useful when speaking with your healthcare team.

GLP Trackr's dose logging lets you record every injection with its date, dose strength, and site, so you have an accurate timeline to share with a surgeon, anaesthetist, or doctor at a glance. The app also generates a doctor report — a structured summary of your journey covering doses, weight changes, side effects, and more — that you can bring to an appointment rather than trying to recall everything from memory.

If you have been tracking symptoms, the side-effect log can show how your body has responded over time, which may be relevant context for your clinical team when they are advising on timing.

Keeping an accurate log now makes those conversations easier later. Download GLP Trackr on the App Store or Google Play and start a free 7-day trial — no commitment needed while you are still planning.

Any decision about when to stop, pause, or change your Mounjaro dose must be made with your prescriber or doctor — never on your own. If you have a surgical procedure coming up, tell your anaesthetic and surgical team about Mounjaro as early as possible. GLP Trackr helps you keep track of your journey; it is not a substitute for clinical advice.
