[02] How it works
The label rule, applied to your dates
Every GLP-1 label has its own missed-dose window. The checker takes the rule from the label for the medicine you pick and works out where you are against it, down to the hour.
The full rules for every medicine, including daily tablets and UK differences, are in our missed GLP-1 dose guide, with each one linked to its label.
[03] Questions
Questions
How late can I take a missed Mounjaro or Zepbound dose?
Up to 4 days (96 hours) after it was due. After that, the labels say to skip it and take the next dose on your usual day.
How late can I take a missed Ozempic dose?
Within 5 days. After 5 days, the label says to skip it and take the next dose on your usual day.
What's the Wegovy missed-dose rule?
In the US, take it if your next dose is more than 2 days (48 hours) away, and skip it if it's less. The UK label uses 5 days instead.
Should I take two doses to catch up?
No. None of the labels say to double up. Once the window has passed, skip the missed dose and carry on as usual.
I missed two weeks. What now?
Talk to your prescriber before your next dose. Some labels, like Wegovy, say a lower restart dose may be needed after missing 2 or more doses in a row.
