IMPORTANT SAFETY INFORMATION ABOUT MOVANTIK

  • MOVANTIK may cause serious side effects, including:
    • Opioid withdrawal. You may have symptoms of opioid withdrawal during treatment with MOVANTIK, including sweating, chills, diarrhea, stomach pain, anxiety, irritability, and yawning. Patients taking methadone to treat their pain may be more likely to experience stomach pain and diarrhea. Tell your doctor if you have any of these symptoms
    • Severe Stomach Pain and/or Diarrhea. This can happen within a few days of starting MOVANTIK and can lead to hospitalization. If either of these side effects occurs, stop taking MOVANTIK and call your doctor immediately
    • 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
  • MOVANTIK can interact with other medicines and cause side effects, including opioid withdrawal symptoms (see symptoms above). Tell your doctor or pharmacist before you start or stop any medicines during treatment with MOVANTIK
  • Before you take MOVANTIK, tell your doctor about all of your medical conditions, including if you:
    • have any stomach, bowel (intestines), 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
  • If you stop taking your opioid pain medicine, stop taking MOVANTIK and tell your doctor
  • Avoid eating grapefruit or drinking grapefruit juice during treatment with MOVANTIK
  • The most common side effects of MOVANTIK include: Stomach (abdomen) pain, diarrhea, nausea, gas, vomiting, headache, and excessive sweating

APPROVED USE FOR MOVANTIK

MOVANTIK is a prescription medicine used to treat constipation that is caused by prescription pain medicines called opioids, in adults with long-lasting (chronic) pain that is not caused by active cancer.

IMPORTANT SAFETY INFORMATION ABOUT MOVANTIK

  • MOVANTIK® (naloxegol) is contraindicated in:
    • Patients with known or suspected gastrointestinal (GI) obstruction and patients at increased risk of recurrent obstruction, due to the potential for GI perforation
    • Patients receiving strong CYP3A4 inhibitors (eg, clarithromycin, ketoconazole) because these medications can significantly increase exposure to naloxegol which may precipitate opioid withdrawal symptoms
    • Patients with a known serious or severe hypersensitivity reaction to MOVANTIK or any of its excipients
  • Symptoms consistent with opioid withdrawal, including hyperhidrosis, chills, diarrhea, abdominal pain, anxiety, irritability, and yawning, occurred in patients treated with MOVANTIK. Patients receiving methadone as therapy for their pain condition were observed in the clinical trials to have a higher frequency of GI adverse reactions that may have been related to opioid withdrawal than patients receiving other opioids. Patients with disruptions to the blood-brain barrier may be at increased risk for opioid withdrawal or reduced analgesia. These patients (eg, multiple sclerosis, recent brain injury, Alzheimer’s disease, and uncontrolled epilepsy) were not enrolled in the clinical studies. Take into account the overall risk-benefit profile when using MOVANTIK in such patients. Monitor for symptoms of opioid withdrawal when using MOVANTIK in such patients
  • Severe abdominal pain and/or diarrhea have been reported, generally within a few days of initiation of MOVANTIK. Monitor and discontinue if severe symptoms occur. Consider restarting MOVANTIK at 12.5 mg once daily
  • Cases of GI perforation have been reported with the use of another peripherally acting opioid antagonist in patients with conditions that may be associated with localized or diffuse reduction of structural integrity in the wall of the GI tract. Monitor for severe, persistent, or worsening abdominal pain; discontinue if this symptom develops
  • Avoid concomitant use of moderate CYP3A4 inhibitors (eg, diltiazem, erythromycin, verapamil) because they may increase the risk of adverse reactions. Use of strong CYP3A4 inducers (eg, rifampin, carbamazepine, St. John’s Wort) is not recommended because they may decrease the efficacy of MOVANTIK. Avoid concomitant use of MOVANTIK with another opioid antagonist due to the increased risk of opioid withdrawal
  • The use of MOVANTIK during pregnancy may precipitate opioid withdrawal in the pregnant woman and the fetus. Because of the potential for adverse reactions, including opioid withdrawal in breastfed infants, advise women that breastfeeding is not recommended during treatment with MOVANTIK
  • The most common adverse reactions with MOVANTIK as compared to placebo in clinical trials were: abdominal pain (21% vs 7%), diarrhea (9% vs 5%), nausea (8% vs 5%), flatulence (6% vs 3%), vomiting (5% vs 4%), headache (4% vs 3%), and hyperhidrosis (3% vs <1%)
