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
Wegovy is injected once a week, on the same day each week, at any time of day, with or without food. The pre-filled FlexTouch pen is injected under the skin of the stomach area, thigh or upper arm, rotating sites. The day can be changed if needed, as long as at least two days pass between doses; your provider and the leaflet cover the technique.
If you miss a dose
The leaflet's rule: take a missed dose as soon as possible within five days of the scheduled time, then continue on your usual day. If more than five days have passed, skip it and take the next dose on the usual day. Never double up. After a longer break, ask your prescriber before restarting: resuming may need a lower step.
Storage
Unused pens are stored in the fridge at 2-8°C, never frozen. Once in use, follow the leaflet's in-use window and temperature limit for your pen. Heat is the enemy: no cars, no direct sun. Travel rules: travelling with GLP-1 medicines.
Sharps
Used needles go in a sharps bin, never household waste; providers supply bins and your pharmacy or council handles disposal locally.

Frequently asked questions
Can I change the time or day I take Wegovy injection?
Yes, within the leaflet's rules: the injection day can move as long as the minimum gap between doses is respected. Your prescriber can confirm what fits your schedule.
What if I take too much Wegovy injection?
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.
