The rules
Three scenarios, three clear answers.
Within 4 days (96 hours)
Take it now
Inject as soon as you remember. Resume your regular schedule the following week. For example, if you inject on Tuesday and remember on Friday (3 days), inject Friday and go back to Tuesday next week.
4 days or more past your usual day
Skip it entirely
Wait for your next regular day. Taking a late dose too close to your next one risks overlapping medication levels, which can worsen stomach side effects.
Missed 2+ consecutive doses
Call your prescriber
You may need to drop back one or two dose levels and work back up gradually. Jumping back to 10mg or 15mg after a break is a common cause of severe nausea.
Decision flow
Step through this to figure out what to do right now.
The cutoff is 96 hours (4 days). This is shorter than semaglutide's 5-day window.
Take the missed dose immediately. Resume your regular schedule the following week.
Do not inject. Wait for your next regular day. Do not try to compensate by injecting sooner.
Restarting at a lower dose may be needed to avoid severe side effects.
Never double-dose
Whether you are on a weekly injection or a daily pill, taking two doses to make up for one missed dose increases the risk of severe nausea, vomiting, and — if you also take insulin or sulfonylureas — dangerously low blood sugar. One missed dose is always better than a double dose.
