Alvimopan is used to help the bowel recover more quickly after bowel surgery, so that you can eat solid foods and have regular bowel movements. Alvimopan is in a class of medications called peripherally acting mu-opioid receptor antagonists. It works by protecting the bowel from the constipation effects of opioid (narcotic) medications that are used to treat pain after surgery.
Alvimopan comes as a capsule to take by mouth. It is usually taken once shortly before bowel surgery. After the surgery, it is usually taken twice a day for up to 7 days or until hospital discharge. Your nurse will bring your medication to you when it is time for you to receive each dose.
This medication should not be prescribed for other uses; ask your doctor or pharmacist for more information.
