    • Opioid withdrawal. You may have symptoms of opioid withdrawal during treatment with MOVANTIK, including sweating, chills, diarrhea, stomach pain, anxiety, irritability, and yawning. If you take methadone to treat your pain, you may be more likely to have stomach pain and diarrhea than people who do not take methadone. Tell your healthcare provider if you have any of these symptoms
    • Severe stomach (abdominal) pain and/or diarrhea. Severe stomach pain and diarrhea can happen when you take MOVANTIK. These problems can happen within a few days after you start taking MOVANTIK and can lead to hospitalization. Stop taking MOVANTIK and call your healthcare provider right away if you have severe stomach pain or diarrhea, or both severe stomach pain and diarrhea
    • Tear in your stomach or intestinal wall (perforation). Stomach pain that is severe can be a sign of a serious medical condition. If you get stomach pain that gets worse or does not go away, stop taking MOVANTIK and get emergency medical help right away
  • Do not take MOVANTIK if you:
    • Have a bowel blockage (intestinal obstruction) or have a history of bowel blockage
    • Are allergic to MOVANTIK or any of the ingredients in MOVANTIK

    • Have any stomach or bowel (intestines) problems, including inflammation in parts of the large intestine (diverticulitis), or inflammation and injury of the intestines caused by reduced blood flow (ischemic colitis), or cancer of the stomach or bowel
    • Have had recent surgery on the stomach or intestines
    • Have any kidney or liver problems
    • Are pregnant or plan to become pregnant. Taking MOVANTIK during pregnancy may cause opioid withdrawal symptoms in you or your unborn baby. Tell your healthcare provider right away if you become pregnant during treatment with MOVANTIK
    • Are breastfeeding or plan to breastfeed. It is not known if MOVANTIK passes into your breast milk. Taking MOVANTIK while you are breastfeeding may cause opioid withdrawal in your baby. You and your healthcare provider should decide if you will take MOVANTIK or breastfeed. You should not breastfeed if you take MOVANTIK
  • Tell your doctor about all of the medicines you take, including prescription and over-the-counter medicines, vitamins, and herbal supplements. Other medicines may affect the way MOVANTIK works
