Alvimopan and Atarax

Alvimopan reduces certain side effects of narcotic medicines that are often used to prevent pain caused by surgery. Narcotic medicine can cause stomach pain, bloating, nausea, vomiting, and constipation. These side effects can delay recovery in patients undergoing gastrointestinal surgery.

Alvimopan helps prevent these side effects without reducing the pain-relieving effects of the narcotic.

Alvimopan is used to help restore normal digestive functioning after surgery to remove a portion of your intestine.

Alvimopan is available only under a special program for short-term use (no more than 15 doses). You must be registered in the program and understand the risks and benefits of taking alvimopan.
