Missed your weekly Zepbound or Wegovy shot? Here are the missed-dose rules from each label, and what to do with compounded medicines.
Life happens. Travel, illness, a pen that didn’t arrive. Here’s what to do.
| Time since missed dose | What the label says |
|---|---|
| Within 4 days (96 hours) | Take the missed dose as soon as possible |
| More than 4 days | Skip it. Take your next dose on your regular day |
Then carry on with your usual weekly schedule. Don’t take two doses to catch up.
The Wegovy label works from how many days remain until your next scheduled dose. If that’s more than 2 days away, take the missed dose as soon as you can. If it’s less than 2 days away, skip it and go back to your regular day. If you miss 2 or more doses in a row, the label says to restart the step-up schedule at a lower dose — so that one is a call for your prescriber, not something to work out yourself.
Missing a few weeks can mean restarting at a lower dose, because your body may no longer be used to the higher one and side effects can come back strongly. Call your prescriber before restarting.
Compounded medicines aren’t FDA-approved and don’t have an FDA label. Ask your prescriber or pharmacy what to do, and write down their advice so it’s ready next time.
If you take the pill with tirzepatide and your prescriber has you restart or change dose after a gap, a new 4-week backup window may apply. Ask when you call.
Beth, 39, usually injects on Sunday. She’s traveling and forgets until Wednesday evening, 3.5 days later. That’s within the 4-day window, so she takes it right away and returns to her usual Sunday the following week. The next time she travels, she sets two reminders.
| It’s been… | Do |
|---|---|
| Less than 4 days | Take it now, then your usual day |
| More than 4 days | Skip it, then your usual day |
| Several weeks | Call your prescriber before restarting |
Yes. The label says you can take it as soon as possible within 4 days of the missed dose.
The label allows changing your dose day as long as doses are at least 3 days (72 hours) apart.
Contact your prescriber or Poison Control (1-800-222-1222 in the U.S.) for advice.
One missed dose is unlikely to make a big difference. Getting back on schedule matters most.
Not by itself. If your prescriber restarts you or changes your dose, ask whether a new window applies.
