Relistor (methylnaltrexone) blocks the effects of opioid medication. An opioid is sometimes called a narcotic.

Relistor reduces constipation caused by using narcotic medicine for 4 weeks or longer. Methylnaltrexone works by preventing constipation without reducing the pain-relieving effects of the narcotic.

Relistor is given to adults who use narcotic medicine to treat severe chronic pain that is not caused by cancer.

Relistor injection is also for use in adults who have advanced illness and are receiving palliative care (treatment to relieve suffering and improve quality of life during a serious illness).

This medicine is usually given after laxatives have been tried without successful treatment of constipation.
