Movantik

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

What is Movantik?

Movantik (naloxegol) is a prescription medicine that blocks certain effects of narcotic medicines. An opioid is sometimes called a narcotic.

Movantik is used to treat opioid induced constipation (OIC) caused by prescription pain medicines called narcotic or opiates, in adults with long-lasting (chronic) pain that is not caused by cancer. Naloxegol treats constipation without reducing the pain-relieving effects of the narcotic.

Movantik is used in people who have been taking narcotic pain medicine for at least 4 weeks, to treat chronic pain that is not caused by cancer.

Important information

You should not use Movantik if you have a blockage in your stomach or intestines.

Tell your doctor if you have symptoms of opioid withdrawal, such as anxiety, feeling irritable, sweating, chills, yawning, stomach pain, and diarrhea.

Stop using this medicine and call your doctor at once if you have severe stomach pain and/or diarrhea (which can lead to serious medical problems).

Many drugs can interact with naloxegol, and some drugs should not be used together. Tell your doctor about all medicines you use, and those you start or stop using during your treatment with Movantik.

How should I take Movantik?

Movantik is usually taken once per day. Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.

Take this medicine on an empty stomach, at least 1 hour before or 2 hours after your first meal of the day.

If you cannot swallow a Movantik tablet whole, you may crush the tablet into powder and mix it with 4 ounces of water. Stir and drink this mixture right away. To get the entire dose, add a little more water to the same glass, swirl gently and drink immediately.

Movantik can also be given through a nasogastric (NG) feeding tube. Crush the tablet into powder and mix it in a container with 2 ounces of water. Draw this mixture into a 60-milliliter syringe. Attach the syringe to the NG tube and push the plunger down to empty the syringe into the tube. Then add 2 more ounces of water to the same container in which you mixed the water and tablet powder. Draw this water into the syringe and use it to flush the NG tube and wash the contents down.

Call your doctor if your symptoms do not improve after 3 days of treatment.

After you stop using your pain medication, you should also stop taking Movantik.
