DoseTrackerMissed your GLP-1 dose? Here's what to do
It happens to almost everyone eventually: a trip, a chaotic week, a pen left in a different fridge — and suddenly you're not sure whether to inject late, skip, or wait. Here's the general picture, and the habit that makes this page unnecessary next time.
The general late-dose windows
Each medication's official prescribing information defines a window during which a missed weekly dose can still be taken:
- Semaglutide (Ozempic®, Wegovy®): a missed weekly dose can generally be taken up to 5 days late. If more time has passed, skip it and take the next dose on your regular day.
- Tirzepatide (Mounjaro®, Zepbound®): the window is generally shorter — up to about 4 days (96 hours). Past that, skip and resume your normal schedule.
Important: these are the general rules from public prescribing information, not personal advice. Your prescriber or pharmacist may direct you differently based on your situation — when in doubt, ask them before injecting.
What never to do
- Never take two doses at once or two doses within a couple of days of each other to "catch up." Doubling up sharply raises the risk of nausea, vomiting and other side effects.
- Don't restart at a high dose after a long gap. If you've missed several weeks, your tolerance may have reset — prescribers often restart at a lower dose. Call before injecting.
Why missed doses matter
Weekly GLP-1s maintain a steady level of medication. A single late dose is usually a non-event, but repeated misses mean fluctuating levels — which can bring back appetite and food noise, and can make side effects worse when you resume. Knowing exactly when your last shot was is the difference between a calm decision and a guess.
How DoseTracker keeps you on schedule
DoseTracker gives you three layers of defense against a missed shot: a reminder on shot day at the hour you choose, a home-screen widget showing your next dose so the countdown is always visible, and a logged shot history — so if you ever do slip, you know precisely how many days late you are before you call your prescriber. When your dose is overdue, the app quietly surfaces it on the home screen.
After a missed dose: reset the rhythm
- Log the late shot (date and dose) so your history stays honest.
- If your prescriber moves your shot day, update your reminder to match.
- Expect a slightly bumpier cycle — a little more nausea than usual is common after a gap; track it and see the nausea timing guide.
