Relistor Tablets and Sulfatrim

• Generic Name: methylnaltrexone

Methylnaltrexone blocks the effects of opioid medication. An opioid is sometimes called a narcotic.

Methylnaltrexone 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.

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

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

Methylnaltrexone may also be used for purposes not listed in this medication guide.
