This page is information, not medical advice. It never tells you which medicine, dose or format is right for you: those decisions sit with you and a qualified prescriber. Spotted an error? Tell us and we'll fix it fast.
Everything here summarises the patient information leaflet and your provider's instructions, which always take precedence. Report suspected side effects through the MHRA Yellow Card scheme.
The routine
One tablet, once a day, at any time of day, with or without food, swallowed whole with or without water. Tablets are not broken, crushed or chewed. That is the whole routine: Foundayo is a small-molecule GLP-1, so it needs none of the fasting rules the Wegovy tablet carries. A consistent time of day helps habit more than chemistry.
If you miss a dose
Follow the leaflet. The principle that holds across the class applies here: a missed day is never made up by taking two tablets in one day. If doses are missed repeatedly or treatment has lapsed for a while, ask your prescriber before restarting rather than resuming at the current dose.
Storage
Room temperature in the original pack, away from heat and moisture. No fridge, no in-use windows, no sharps. It is the simplest storage profile of the four treatments, which also makes it the easiest to travel with: travelling with GLP-1 medicines.
Dose changes
Every dose change is prescriber-led, with at least 30 days at each step: the full ladder is at Foundayo dose schedule.

Frequently asked questions
Can I change the time or day I take Foundayo?
The tablet is daily; keeping a consistent time helps but the leaflet governs any specifics. Ask your prescriber about anything beyond the leaflet's flexibility.
What if I take too much Foundayo?
Contact your prescriber or NHS 111 promptly, and 999 if you feel seriously unwell. Do not wait to see how it goes: too much of a GLP-1 medicine can cause severe nausea, vomiting and dehydration.
Where do I find the official instructions?
The patient information leaflet in the pack, also published on the electronic medicines compendium (linked below), is the authoritative instruction set. This page summarises it and never replaces it.
