RELISTOR (methylnaltrexone) is generally considered safe when prescribed for the right patient and used as directed. It is used to treat constipation caused by opioid pain medicines.
Common side effects include abdominal pain, diarrhea, nausea, headache, sweating, and bloating. RELISTOR should not be used if you have a known or suspected bowel obstruction because of the risk of a serious bowel perforation. People with conditions such as diverticulitis, Crohn’s disease, ulcers, or certain gastrointestinal cancers may also need extra caution.
Stop RELISTOR and seek medical advice promptly if you develop severe, persistent, or worsening abdominal pain or severe diarrhea. Symptoms of opioid withdrawal can also occasionally occur.
