Can you drink alcohol while taking Alvimopan?
Last updated September 7, 2026.
**Alvimopan itself has no known interaction with alcohol, but you should not drink while taking it, because it is given only in the hospital during the first days after bowel surgery.** Alvimopan is a short course, limited to 15 doses over about a week, and it is used to help your bowels start moving again after an operation. Alcohol pushes in the other direction: it irritates the stomach, adds to nausea, and can worsen the constipation that opioid pain medicine already causes. It also deepens the sedation and slowed breathing that come with opioids, which matters most in the days right after surgery. Once you are home and finished with alvimopan, ask your surgeon when drinking is reasonable again, since antibiotics, blood thinners, and liver or pancreas conditions all change the answer.
What to do
- Know the setting: Alvimopan is an inpatient medicine limited to about 15 doses over 7 days, so it is not something you take home and drink around.
- Skip alcohol while on opioids: Combining alcohol with the opioid pain medicine used after surgery increases sedation and slows breathing.
- Protect your gut recovery: Alcohol irritates the stomach and adds to nausea, working against the bowel recovery alvimopan is meant to speed up.
- Choose fluids that help: Water and clear fluids support recovery, while alcohol pulls fluid out and can worsen constipation.
- Share your full history: Tell the team if you took opioids daily for more than a week before surgery or if you drink heavily, since both change the plan.
- Ask before restarting: Check with your surgeon about when alcohol fits again, especially if you go home on antibiotics or blood thinners.
