What if I missed a Wegovy dose?

Less than 5 days since your missed dose: take it now and resume your regular weekly schedule. More than 5 days: skip the missed dose and take your next dose on its regular day. Never double up.

What if I missed more than one week?

If you've missed 2 or more consecutive weekly doses, contact your prescriber before restarting. Many clinicians recommend stepping back one dose level to reduce GI side effects on restart.

I missed a Rybelsus tablet — what now?

Skip the missed tablet entirely. Take your next dose at the usual time the next morning. Do not take two tablets on the same day.

Can I change my regular injection day?

Yes. The FDA label allows changing your weekly dosing day as long as at least 48 hours have passed since your last dose. After changing, your new weekly schedule begins from the new day.

Missed Wegovy Dose? Here's What to Do

A quick decision tool based on the Wegovy and Ozempic FDA labels. Tell us when your dose was scheduled and we'll tell you whether to take it now or skip.

Decision tool

Which semaglutide are you taking?

When were you supposed to inject?

The day and time of your regularly scheduled dose (the one you missed).

Never double up. Taking two doses within the same week dramatically increases the risk of severe nausea, vomiting, dehydration, and in rare cases pancreatitis. Always skip rather than double.

The decision, as a flowchart

Less than 5 days (120 hours) since your missed dose?
→ Take the missed dose now. Resume your regular weekly day.

5 days or more since your missed dose?
→ Skip the missed dose. Take your next dose on its regularly scheduled day.

Missed 2+ consecutive weekly doses?
→ Contact your prescriber. You may need to restart at a lower dose to avoid GI rebound.

Based on: Wegovy prescribing information (Section 2.3) and Ozempic prescribing information (Section 2.2).

Why missing matters (and what not to do)

Semaglutide's once-weekly dosing relies on its long half-life (~1 week). That means one missed dose doesn't immediately send your blood levels crashing. A short gap is forgivable; a long one resets some of your acclimation.

What doubling does

Taking a "catch-up" dose within the same week effectively doubles your exposure. Because semaglutide accumulates slowly, this does not catch you up on weight loss — it just spikes GI side effects and dehydration risk. The FDA label is explicit: never double.

What to do if you've stopped for weeks

If you've been off semaglutide for more than two consecutive weeks, don't simply resume at your previous dose. Contact your prescriber. Many clinicians recommend stepping back one titration level (e.g., from 2.4 mg → 1.7 mg for 4 weeks) to prevent the return of acute GI effects.

Reminder: This tool handles routine single missed doses. If you've missed a dose because of a new symptom (e.g., severe abdominal pain, persistent vomiting), call your prescriber before restarting.
