What if I miss a dose?

Take within 5 days (Wegovy/Ozempic) or 4 days (Zepbound/Mounjaro). If more time passed, skip and resume normal schedule. Never double up.

Can I take two doses at once?

No. Never double up. Can cause severe nausea, vomiting, and dangerous side effects.

Will missing a dose affect weight loss?

One missed dose is unlikely to affect results. Frequent missed doses can reduce efficacy and lead to appetite return.

How to reschedule injection day?

Take next dose on new preferred day if 48+ hours since last dose. Continue on new weekly schedule.

What if I miss multiple doses?

Contact provider. May need to restart at lower dose, especially if off medication 2+ weeks.

What happens if I miss a GLP-1 dose?

If you miss a dose, take it as soon as you remember if it is within 5 days (Wegovy, Ozempic) or 4 days (Zepbound, Mounjaro) of your scheduled day. If more than 5 days have passed, skip the missed dose and take your next dose on the regular schedule. Do not double up.

Can I take two GLP-1 doses at once to make up for a missed one?

No. Never take two doses at once. This can cause severe nausea, vomiting, and potentially dangerous side effects. Always take only one dose and resume your normal schedule.

Will missing a GLP-1 dose affect my weight loss?

Missing one dose is unlikely to significantly affect your weight loss. The medication remains in your system for 4-5 weeks (semaglutide) or 5-6 days (tirzepatide). However, frequently missing doses can reduce efficacy and lead to appetite return and weight regain.

How do I reschedule my GLP-1 injection day?

You can change your injection day by simply taking your next dose on the new preferred day, as long as at least 48 hours have passed since your last dose. Then continue on the new weekly schedule.

What if I miss multiple GLP-1 doses?

If you miss 2 or more consecutive doses, contact your provider. You may need to restart at a lower dose to reduce side effects, especially if you have been off the medication for more than 2 weeks.

What to do if you miss a dose: quick reference

Medication	Take if within	If more time passed
Wegovy (semaglutide)	5 days	Skip, resume next scheduled dose
Ozempic (semaglutide)	5 days	Skip, resume next scheduled dose
Zepbound (tirzepatide)	4 days	Skip, resume next scheduled dose
Mounjaro (tirzepatide)	4 days	Skip, resume next scheduled dose
Foundayo (orforglipron)	Same day	Skip, take next day's dose

Step-by-step: what to do when you miss a dose

Check how long it has been: Count the hours/days since your scheduled injection time.
If within the window: Inject as soon as you remember. Then continue your regular weekly schedule from that point.
If outside the window: Skip the missed dose entirely. Take your next dose on the regular scheduled day.
Never double up: Do not take two doses to compensate. This can cause severe side effects.
Monitor side effects: After a missed and resumed dose, you may experience slightly more nausea than usual.
Contact your provider if: You miss 2+ consecutive doses or have been off for 2+ weeks.

Why you should never double up

Taking two GLP-1 doses at once can cause severe gastrointestinal side effects including persistent vomiting, severe dehydration, and potentially acute pancreatitis. The medication has a long half-life (semaglutide: ~1 week, tirzepatide: ~5 days), meaning your previous dose is still active in your body.
