Side effects & support
Plain-English information about common side effects of the weight-loss medications compared on Health Compare UK — for Mounjaro, Wegovy, Wegovy Pills and Foundayo Pills — with a clear difference between everyday effects, symptoms to discuss with a clinician, and signs that need urgent help.
Information only — not medical advice. This page summarises publicly available UK information from the NHS, the MHRA and the official Patient Information Leaflets. It is general information, not a diagnosis, a recommendation, or a substitute for professional advice. Side effects vary between people and the lists are not exhaustive. Always read the leaflet supplied with your medicine and speak to your GP, prescribing clinician or pharmacist about anything that concerns you. In an emergency, call 999.
If you have severe symptoms — such as swelling of the face or throat, difficulty breathing, or severe stomach pain spreading to your back with vomiting — call 999 straight away or go to your nearest A&E.
