Missing a dose happens to almost everyone. What matters is what you do next. The right move depends on how close you are to your next scheduled dose and which drug you take, and one rule holds for all of them: never double up.
Why there's no one answer
Missed-dose rules for GLP-1 medications depend on how long it's been since the missed dose and which medication you're on. Weekly injections, daily injections and daily pills each follow different logic. Getting it wrong matters both ways. Taking a dose too close to the next one can pile up side effects, while skipping incorrectly can set back your titration progress or blood sugar control. This guide covers the general pattern; confirm the rule for your own medication in the patient information that comes with your prescription, or ask your pharmacist, because the exact windows vary by drug.
Weekly injections
For once-weekly medications (semaglutide, tirzepatide, dulaglutide), the labels follow the same pattern. If you remember within the allowed window, take the missed dose as soon as you can, then go back to your usual injection day. If you remember too late, close to your next scheduled dose, skip the missed one and take your next dose on the regular day. Don't double up. As of the current labels (checked September 2026), the windows are:
- Ozempic: take it within 5 days of the missed dose.
- Wegovy injection: take it if your next dose is more than 2 days away.
- Mounjaro and Zepbound: take it within 4 days (96 hours).
- Trulicity: take it if there are at least 3 days (72 hours) until your next dose.
Labels change, so check these against your own medication's patient information.
Wegovy has one more rule with real safety weight. If you've missed two or more Wegovy injections in a row, the label says to restart the dose climb at a lower dose to lower the risk of stomach side effects. Don't just pick up where you left off; see restarting after a gap, which lays out the rules drug by drug.
If you want to move your injection day for good, the labels allow it as long as the doses stay far enough apart: at least 2 days (more than 48 hours) for Ozempic, and at least 3 days (72 hours) for Mounjaro, Zepbound and Trulicity.
Missing a dose by accident is different from spacing doses out on purpose. If you're thinking about taking your weekly injection every 10 or 14 days deliberately, see stretching your GLP-1 dose past 7 days for what that does to drug levels and what the early evidence shows.
Daily injections
For once-daily liraglutide, the labels don't offer a catch-up window, because the drug clears quickly. If you miss a daily dose, skip it and take the next one at the usual time. Don't double up. If more than 3 days have passed since your last dose of Saxenda or Victoza, the label says to restart at the 0.6 mg starting dose and re-titrate, so a longer gap is worth a call to your prescriber. (Label wording current as of 2026; re-check your own patient information.)
Daily pills
The semaglutide pills (Wegovy tablets, Ozempic tablets and Rybelsus) use the simplest rule: if you miss a dose, skip it and take the next one the following day. Foundayo (orforglipron) is different. Take a missed dose as soon as you can, but don't double up the next one, and if you miss 7 or more doses in a row the label says to restart the dose climb at a lower dose.
Why you should never double a dose to catch up
No GLP-1 label tells you to double up to make up for a missed dose, and doing it raises the risk of significant side effects, because the dose is closely tied to how bad stomach symptoms get (see our GI side effects overview, and our guide on what to do after an accidental double dose if it has already happened).
If you're unsure
Call your pharmacist or your prescriber's office instead of guessing. It's a quick question for either of them, and getting it right is worth the call.
