What happens if you miss a dose of Alvimopan?

Short answer

**Alvimopan is a hospital-only medicine handed to you by nursing staff, so a missed or late dose is something your care team manages, not something you correct on your own.**

It is dispensed under a restricted FDA program to inpatients recovering from bowel surgery, and it is not sent home with you. The usual pattern is one capsule before surgery, then one capsule twice a day starting the day after, with a hard cap of 15 total doses and no more than 7 days. If a dose is late, staff give it when they can and continue the regular schedule instead of doubling up. A single skipped dose does not cause withdrawal and does not undo the earlier doses, though the return of normal bowel function may take slightly longer. Speak up if a scheduled dose never arrives, since the count and the calendar both matter here.

What to do about a missed alvimopan dose

1Ask your nurse first:If a dose seems to have been skipped, tell the nurse caring for you rather than waiting for the next round.
2Never double up:Two capsules at once is not the fix for a late dose, and the total is capped at 15 doses.
3Watch the 7 day limit:Treatment stops at 7 days or at discharge, whichever comes first, so late doses are not added to the end.
4Do not expect a home supply:Alvimopan is not prescribed for use after you leave the hospital, so there is nothing to refill or restart.
5Mention your opioid history:Tell the team if you took opioids daily for more than 7 days right before surgery, since that changes whether this drug is safe for you.
6Report new symptoms:Call the team for chest pain, severe belly pain, or bowel function that stalls, and get urgent care for chest pain that does not ease.

Common questions

What happens if you miss a dose of Alvimopan?

Alvimopan (Entereg) is dispensed only inside hospitals under a restricted FDA program, so you do not manage the schedule at home. If a dose is late, nursing staff give it when they can and keep the twice daily pattern going. Doses are never doubled to catch up. The course is capped at 15 doses over no more than 7 days and ends at discharge, so a skipped dose is not made up later. Missing one dose does not cause withdrawal, and it may only slow the return of normal bowel function a little. Tell your nurse if a scheduled dose was not given, and ask your surgical team where you are in the course.
