Just received a message from my GP surgery. Posting here as I wasn't aware. A quick Google suggests it's been known about for a while though. Not got any planned operations coming up, and they tend to ask about medicines you're taking anyway, but it might be worth knowing if your Mounjaro prescription isn't on your NHS records.
MedExpress informed my GP about the prescription from them, but The Care Pharmacy don't seem to have ever let my GP know.
"Dear xxxxxxxx,
We have received new safety information for patients taking Mounjaro (Tirzepatide) either for diabetes or weight loss. This medication has been shown to cause problems when patients undergo a general anaesthetic so it is important to inform your anaesthetist about this prior to any surgical procedure. Otherwise please carry on taking your medication as usual. Please do not hesitate to contact your Pharmacist if you have any concerns.
