Missed a GLP-1 Dose? What the Labels Say for Ozempic, Wegovy, Zepbound and Mounjaro

A missed GLP-1 dose is common, and what to do next depends on which medication you take. Each US label sets its own window for a late dose, its own minimum gap between doses, and, for a few products, a rule about restarting at a lower dose after several misses. This guide collects those rules in one place, as of September 2026. Use it to prepare for a quick call with your prescriber or pharmacist, not to replace one.

What should you do if you miss a GLP-1 dose?

Find your product in the table below and check how much time has passed. The US labels allow most weekly injections to be taken within roughly 4 to 5 days of the missed day; after that, they say to skip it and keep your usual day. Missed daily semaglutide pills are skipped. Never take two doses close together to catch up.

Step by step:

1. Write down the date and time of the dose you missed and of your next scheduled dose.
2. Find your product in the table. For Ozempic, Zepbound and Mounjaro, count the time since the missed dose. For Wegovy injection and Trulicity, count the time until your next dose.
3. If you are inside the window, the labels say to take the dose and then return to your usual day. If you are outside it, they say to skip the dose and take the next one on your usual day.
4. If you have missed more than one dose, stop and read the section on missed doses in a row before you inject.
5. Log what you did, on paper or in a tracker such as GLP Calendar, so your next decision is based on real dates rather than memory.

What does each US label say about a missed dose?

The rules differ by product. The US labels allow a late Ozempic dose within 5 days and a late Zepbound or Mounjaro dose within 4 days, allow a late Wegovy or Trulicity shot only while the next dose is more than 2 or at least 3 days away, and say to skip a missed semaglutide pill. Each rule below comes from the current US label; confirm with your prescriber or pharmacist before acting on it.

A few details the table cannot hold:

• Wegovy's restart rule is new. The version revised in May 2026 still said patients could "resume dosing as scheduled or, if needed, reinitiate" the escalation schedule. The June 2026 revision says to restart escalation at a lower dose "to reduce the risk of gastrointestinal adverse reactions." It does not name the dose, so your prescriber chooses it.
• Liraglutide restarts differ slightly. Saxenda restarts at 0.6 mg and follows the usual escalation schedule; Victoza restarts at 0.6 mg and is then adjusted at the prescriber's discretion.
• Foundayo has no cutoff for a late dose, but its Medication Guide says not to take 2 doses in the same day.

How do EU labels differ?

Semaglutide is the main difference. The EU Wegovy label uses a simple 5-day window, like Ozempic, and says a lower restart dose "should be considered" if more doses are missed. Both the EU Wegovy and EU Ozempic labels require at least 3 days (more than 72 hours) between doses when you change your dosing day, compared with 2 days in the US. If you fill a prescription outside the US, follow the leaflet in that pack.

Why are the missed-dose windows different?

Because the drugs last different lengths of time in the body. The US labels give a half-life of about 1 week for semaglutide, about 5 days for tirzepatide and dulaglutide, 29 to 49 hours for orforglipron and about 13 hours for liraglutide. The longer the half-life, the more medicine is still active when a dose is late.

A weekly drug fades slowly. The Ozempic label says semaglutide stays in the circulation for about 5 weeks after the last dose, so a shot taken a few days late lands on top of medicine that is still working.

Each weekly window also ends where the next dose would come too soon. A Zepbound dose taken 4 days late leaves 3 days (72 hours) before the next scheduled dose, the label's minimum gap. An Ozempic dose taken 5 days late leaves 2 days, again the minimum.

Daily drugs fade within a day or two, so several missed days leave much less medicine on board. The liraglutide labels restart at 0.6 mg after more than 3 days off "to reduce the risk of gastrointestinal adverse reactions associated with reinitiation," and Foundayo re-escalates after 7 missed doses for the same stated reason. More in how long GLP-1 medications stay in your body.

What if you missed two or more doses in a row?

Only three US labels give a rule. Wegovy injection (2 or more weekly doses in a row) and Foundayo (7 or more daily doses in a row) say to restart dose escalation at a lower dose, and liraglutide restarts at 0.6 mg after more than 3 days. The Ozempic, Zepbound, Mounjaro and Trulicity labels do not address repeated missed doses.

The patient-facing wording is useful here:

• Wegovy: "If you miss doses of WEGOVY for 2 or more consecutive weeks, contact your healthcare provider to talk about how to restart your treatment."
• Foundayo: if you miss it "for 7 or more days in a row," call your healthcare provider about how to restart.
• Saxenda: if you miss your dose "for 3 days or more," call your healthcare provider about how to restart. (The prescribing information uses "more than 3 days" as the restart point.)

Silence in the other labels is not permission to pick up where you left off; the restart plan is a clinical decision. A practical rule of thumb: after two or more missed weekly doses, the point at which the Wegovy label asks for a lower restart, call your prescriber before your next injection, whatever GLP-1 you use.

Do you have to restart Zepbound at 2.5 mg after 14 days?

Not according to the US label. Many websites say the FDA requires a restart at 2.5 mg after 14 days without Zepbound, but the current Zepbound and Mounjaro labels (revised August 2026) contain no such rule. They cover a single missed dose (the 4-day window) and the 3-day minimum gap when changing your day, and nothing about longer breaks.

That does not mean your old dose is right after a long break. Your prescriber may choose a lower one based on how long you were off and how you tolerated each step. The tirzepatide dose steps start at 2.5 mg, which is one option a prescriber may pick, not a label requirement. Ask before the next injection rather than guessing.

Can you change your weekly injection day?

Yes. The US labels allow a new day as long as doses stay far enough apart: at least 2 days (more than 48 hours) for Ozempic and Wegovy, and at least 3 days (72 hours) for Zepbound, Mounjaro and Trulicity. After the switch, keep injecting on the new day each week. The EU semaglutide labels require 3 days.

A worked example, for someone on Zepbound who injects on Mondays and wants to move to Thursdays:

1. Count from the last dose. Monday to Thursday is 3 days, which meets the 72-hour minimum, provided the Thursday shot is not earlier in the day than the Monday one.
2. Take the next dose on Thursday.
3. Keep Thursday as the injection day from then on.

Count hours, not just dates, if you inject at different times of day: Monday evening to Thursday morning is less than 72 hours. And after a late dose, the labels say to return to your usual day; keeping the new day instead counts as a day change, so the same spacing rule applies.

What should you never do after a missed dose?

Never double up or squeeze two doses close together to catch up. The Zepbound, Mounjaro and Trulicity Medication Guides say not to take 2 doses within 3 days of each other, the Foundayo and liraglutide labels say not to take an extra dose, and the pill labels allow only one tablet a day.

• Do not take two weekly doses closer together than your label's minimum gap.
• Do not add an extra daily shot or pill, or raise the dose, to make up for one you missed.
• Do not take a missed Wegovy, Rybelsus or Ozempic pill later in the day. Skip it.
• Do not restart at your previous dose after several missed weeks without asking your prescriber.
• Do not dial a partial dose by counting pen clicks to "ease back in." Pen instructions say not to count clicks, and there is no clinical evidence for this kind of microdosing. See how multi-dose pens work.

If you did take two doses too close together, the labels say to call your healthcare provider or Poison Help at 1-800-222-1222, or go to the nearest emergency room right away.

When should you call your prescriber?

Call before your next dose if you have missed two or more weekly doses in a row, 7 or more Foundayo doses, or more than 3 days of Saxenda or Victoza, or if you are unsure which dose to restart on. Get help right away for the red-flag symptoms the labels list, especially after restarting.

The Zepbound label says most nausea, vomiting and diarrhea "occurred during dose escalation and decreased over time," and the Wegovy label ties its lower-dose restart to the same risk. The Medication Guides list these warning signs:

• Severe pain in your stomach area that will not go away, with or without vomiting, sometimes spreading to your back. The guides say to stop the medicine and call your provider right away.
• Nausea, vomiting or diarrhea that does not go away, which can cause dehydration and kidney problems.
• Swelling of your face, lips, tongue or throat, problems breathing or swallowing, severe rash or itching, fainting or dizziness, or a very rapid heartbeat. The guides say to get medical help right away.

Bottom line

• Weekly shots, per the US labels: Ozempic within 5 days, Zepbound and Mounjaro within 4 days, Wegovy if the next dose is more than 2 days away, Trulicity if at least 3 days remain. Otherwise the labels say to skip it and keep your usual day.
• Daily pills: the labels say to skip a missed semaglutide pill, and to take a missed Foundayo tablet as soon as possible but never two in one day.
• Several misses: Wegovy (2 or more weeks), Foundayo (7 or more days) and liraglutide (more than 3 days) restart lower. The other labels are silent, so ask before restarting.
• Never double up, and confirm any plan with your prescriber or pharmacist.
