Short answer Alvimopan and dependence: what to know Common questions Related questions Sources**No, alvimopan is not addictive, and it does not cause cravings, tolerance, or withdrawal.**
Alvimopan is an opioid receptor blocker that works almost entirely in the gut and does not meaningfully reach the brain, so it produces no high and no dependence. It is used in the hospital after bowel surgery to help the intestines start moving again, and dosing is capped at 15 doses over a maximum of 7 days. That cap comes from a cardiovascular safety concern seen with long term use in a different setting, not from any risk of addiction. The medicine you may worry about is the opioid pain reliever given alongside it, since that class can cause dependence. Ask your surgical team how they plan to taper opioid pain medicine once you are eating and moving.
Alvimopan and dependence: what to know
Common questions
Is Alvimopan addictive?
Alvimopan (brand name Entereg) blocks opioid receptors in your gut rather than in your brain, so it does not cause euphoria, tolerance, cravings, or withdrawal. It is given in the hospital to help your bowels start working again after bowel resection, and the FDA limits treatment to 15 doses over no more than 7 days. That limit reflects a cardiovascular safety signal seen with long term use, not an addiction risk. You do not take alvimopan home and there is no taper. If you are also getting opioid pain medicine, that drug carries the dependence risk, so ask your team about stepping down from it.
