Short answer: If it has been 4 days (96 hours) or less since the missed dose, the Zepbound label says to take it as soon as possible. If more than 4 days have passed, skip it and take the next dose on your usual day. Do not take two doses within 3 days (72 hours) of each other.
| Situation | What the label says |
|---|---|
| Schedule | Once weekly |
| Missed by 4 days (96 h) or less | Take it as soon as possible (2.3) |
| Missed by more than 4 days | Skip it; take the next dose on the usual day (2.3) |
| Minimum time between doses | At least 3 days (72 hours) (2.3) |
| Several weeks missed | No specific rule in the Zepbound label |
| Changing your injection day | Allowed if doses stay at least 3 days apart (2.3) |
Section 2.3 of the Zepbound prescribing information ("Recommendations Regarding Missed Dose") says to take a missed dose as soon as possible within 4 days (96 hours). Then return to your regular weekly schedule.
This applies the same way to the single-dose pen, the KwikPen and the single-dose vial. The rule is about timing, not the device.
Skip the missed dose and take the next dose on your regularly scheduled day.
No. The Medication Guide says not to take 2 doses of Zepbound within 3 days (72 hours) of each other.
The Zepbound label does not give a separate rule for restarting after several missed weeks. Whether to resume your usual dose or restart at a lower one is a question for your prescriber, especially if stomach side effects were a problem when you first started.
People often expect Zepbound to have the same 2-missed-weeks rule as Wegovy. It does not: that rule is only in the Wegovy label. The Zepbound label starts at 2.5 mg weekly and steps up by 2.5 mg after at least 4 weeks on a dose. Tirzepatide's elimination half-life is about 5 to 6 days in people with overweight or obesity (section 12.3).
Yes, if necessary, as long as the time between the two doses is at least 3 days (72 hours), per section 2.3.
