Why is this medication prescribed?

Movantik (generic name: naloxegol) is a medication prescribed to treat opioid-induced constipation (OIC) in adults who are taking opioid pain medications on a regular basis and are experiencing constipation as a side effect. Opioid pain medications, such as morphine, oxycodone, and others, can slow down the movement of the gastrointestinal tract, leading to constipation. Movantik works by blocking the effects of opioids in the gut, which helps to relieve constipation without reducing the pain-relieving effects of the opioids.

How should this medicine be used?

Here are general guidelines on how Movantik should be used, but always follow your doctor’s specific instructions:

  • Dosage: Movantik is typically available in tablet form, and the recommended starting dose is usually 25 milligrams (mg) taken once daily. Your doctor may adjust the dose based on your individual response to the medication.
  • Timing: It is usually taken at the same time each day, with or without food. Follow your doctor’s recommendations for the best time to take it.
  • Swallow whole: Swallow the tablet whole with water. Do not crush, break, or chew the tablet.
  • Avoid grapefruit: Avoid consuming grapefruit or grapefruit juice while taking Movantik, as it may interact with the medication.
  • Stay hydrated: Make sure to drink plenty of fluids while taking Movantik to help prevent constipation.
  • Continue opioid pain medication: Continue taking your prescribed opioid pain medication as directed by your doctor. Movantik is designed to relieve constipation without reducing the pain relief provided by opioids.
  • Monitor for side effects: Be aware of any side effects or adverse reactions while taking Movantik. Common side effects may include abdominal pain, diarrhea, nausea, and headache. If you experience severe or persistent side effects, contact your healthcare provider.
  • Follow your doctor’s advice: It’s essential to follow your doctor’s instructions and not change the dose or stop taking Movantik without consulting them.

Remember that Movantik is specifically intended to treat opioid-induced constipation, and it should not be used for other types of constipation unless recommended by your healthcare provider. If you have any questions or concerns about the use of Movantik, discuss them with your healthcare provider for personalized guidance.

What special dietary instructions should I follow?

There are no specific dietary restrictions associated with taking Movantik (naloxegol). You can generally continue with your normal diet while using this medication.

What should I do if I forget a dose?

If you forget to take a dose of Movantik, here are some general guidelines:

  • Timing: Take the missed dose as soon as you remember it.
  • Next Dose: If it’s close to the time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not double the dose to make up for the missed one.
  • Consult Your Healthcare Provider: If you frequently forget doses or have concerns about missed doses, it’s a good idea to discuss this with your healthcare provider. They can provide guidance on how to manage missed doses effectively.
