Missed a Mounjaro or Wegovy dose? What the leaflets say.
There's a grace window for a late dose, and a point where the leaflet says skip instead.
There's a grace window for a late dose, and a point where the leaflet says skip instead.
Missing a weekly dose happens: travel, a delayed delivery, a forgotten Sunday. Both leaflets give you a window.
Mounjaro
If it's within 4 days (96 hours) of the missed dose, take it as soon as you can, then continue on your normal day. If more than 4 days have passed, skip it and take the next dose on schedule. Never double up.
Wegovy
The window is 5 days: within that, take the dose and carry on; beyond it, skip to the next scheduled day. Again, never take two doses to catch up. If you are unsure what your pen holds per dose, the Wegovy click calculator on iGovy shows it pen by pen.
Daily tablets
For the Wegovy pill or Foundayo, the rule is the familiar one: if you miss a day, skip it and take the next tablet at the usual time, no doubling.
Repeated missed doses, or a gap of more than a couple of weeks, is a prescriber conversation, you may be advised to restart lower. Sources: the official patient leaflets at the electronic medicines compendium.
