Naloxegol

Generic Name: naloxegol (nal-OX-ee-gol)
Brand Name: Movantik

Naloxegol is used for:

Treating constipation caused by opioid medicines in certain patients. It may also be used for other conditions as determined by your doctor.

Naloxegol is an opioid antagonist. It works by decreasing the effect of opioid medicines in the stomach and bowel, which helps to decrease constipation.

Do NOT use naloxegol if:

  • you are allergic to any ingredient in naloxegol
  • you have severe liver problems or a history of stomach or bowel blockage
  • you are taking carbamazepine, clarithromycin, itraconazole, ketoconazole, rifampin, or St. John's wort
  • you are taking another opioid antagonist (eg, methylnaltrexone)

Contact your doctor or health care provider right away if any of these apply to you.

Before using naloxegol:

Some medical conditions may interact with naloxegol. Tell your doctor or pharmacist if you have any medical conditions, especially if any of the following apply to you:

  • if you are pregnant, planning to become pregnant, or are breast-feeding
  • if you are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement
  • if you have allergies to medicines, foods, or other substances
  • if you have kidney or liver problems
  • if you have nausea, vomiting, stomach pain or swelling, or stomach or bowel problems (eg, cancer, ulcer, Ogilvie syndrome)

Some MEDICINES MAY INTERACT with naloxegol. Tell your health care provider if you are taking any other medicines, especially any of the following:

  • Clarithromycin, diltiazem, erythromycin, itraconazole, ketoconazole, methylnaltrexone, or verapamil because they may increase the risk of naloxegol's side effects. The risk of opioid withdrawal symptoms may also be increased
  • Carbamazepine, rifampin, or St. John's wort because they may decrease naloxegol's effectiveness

This may not be a complete list of all interactions that may occur. Ask your health care provider if naloxegol may interact with other medicines that you take. Check with your health care provider before you start, stop, or change the dose of any medicine.

How to use naloxegol:

Use naloxegol as directed by your doctor. Check the label on the medicine for exact dosing instructions.

  • Naloxegol comes with an extra patient information sheet called a Medication Guide. Read it carefully. Read it again each time you get naloxegol refilled.
  • Take naloxegol by mouth on an empty stomach at least 1 hour before or 2 hours after the first meal of the day.
  • Swallow naloxegol whole. Do not break, crush, or chew before swallowing.
  • Do not eat grapefruit or drink grapefruit juice while you use naloxegol.
  • If you miss a dose of naloxegol, take it as soon as possible. If it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not take 2 doses at once.

Ask your health care provider any questions you may have about how to use naloxegol.

Important safety information:

  • Tell your doctor or dentist that you take naloxegol before you receive any medical or dental care, emergency care, or surgery.

  • Symptoms of opioid withdrawal have happened with naloxegol. Call your doctor right away if you have increased sweating, chills, unusual diarrhea or stomach pain, anxiety, irritability, or yawning.
  • If you are taking methadone for pain, talk with your doctor. Stomach problems (eg, diarrhea, stomach pain) may happen more often in people taking methadone with naloxegol than in people taking other opioid pain medicines.
  • PREGNANCY and BREAST-FEEDING: If you become pregnant, contact your doctor. You will need to discuss the benefits and risks of using naloxegol while you are pregnant. It is not known if this medicine is found in breast milk. Do not breast-feed while taking naloxegol.
