Lubiprostone (Oral)

Lubiprostone increases the release of fluid in the intestines to make bowel movements (passing of stool) easier.


Lubiprostone is a prescription medicine that helps relieve abdominal discomfort and bloating, improve the texture of stools, decrease the strain of passing stools, and decrease the feeling that you've not fully relieved yourself.

Lubiprostone belongs to the class of drugs called laxatives, which work by releasing more fluid in the intestines, making bowel movements (passing of stool) easier.

Lubiprostone is prescribed for treating idiopathic constipation in adults. The term idiopathic means that the constipation has no known cause and factors like diet, side effects from drugs, or underlying illness have been ruled out.

This medication may be prescribed for the treatment of constipation caused by opioids or narcotic pain medicines. In some situations, low doses of Lubiprostone are prescribed for the treatment of irritable bowel syndrome along with constipation in women aged 18 and over.

Lubiprostone is a capsule and is normally taken twice each day with water and food. You should swallow the capsule whole. Don't chew, break, or crush it.

The FDA approved Lubiprostone in 2006. It's made by Takeda and marketed under the brand name Amitiza.

Common Lubiprostone side effects include stomach pain, diarrhea, and nausea.

Take this medication exactly as ordered by your physician. The recommended dose of this medication varies based on the medical disorder being treated and other medical disorders you may have.

The recommended doses of Lubiprostone are as follows:

  • 24 micrograms taken twice daily for chronic idiopathic constipation
  • 8 micrograms taken twice daily for irritable bowel syndrome along with constipation
  • 24 micrograms taken twice daily for opioid-induced constipation

If you've been using Lubiprostone for 14 days and your symptoms haven't improved at all, let your physician know.

Lubiprostone is available as a capsule and should be taken orally (by mouth) with water and food. It's normally 2 times daily. Please swallow the capsules whole. Don't break, crush, or chew them.

It's advisable to take this medication with water and food to reduce the chances of suffering nausea.

Take at least 6-8 glasses of fluid daily. This will help soften your stool.

If you've missed a Lubiprostone dose, just skip it. Don't take two capsules to compensate for your missed dose.

A healthy diet consisting of fiber (e.g. wholegrain cereals and breads, bran, green leafy vegetables, and fruit) with 6-8 glasses of water daily and exercising every day are vital for keeping healthy bowel function. People with constipation problems should avoid foods like pastries, sugar, puddings, cheese, cake, and sweets as they can worsen their problem.

Lubiprostone may help ease symptoms but is not a cure for constipation. Keep taking Lubiprostone even if you start to feel well and don't stop taking it without consulting your healthcare provider.

If you've taken excess Lubiprostone, get in touch with your poison control agency or seek emergency medical care right away.


Research shows that there's little chance of medications interacting with Lubiprostone.

However, there's some evidence to show that using opioid-type medications like Dolophine (Methadone) may make Lubiprostone less effective.

You may feel dizzy after taking Lubiprostone. Taking alcohol may worsen this effect.

Lubiprostone may interact with other drugs, such as over-the-counter and prescription drugs, herbal products, and vitamins. Tell all your healthcare professionals about all drugs you're using and any drug you begin or stop using.


Before you take Lubiprostone:

Tell your pharmacist and doctor if you have allergies to Lubiprostone, any ingredients in Lubiprostone capsules, or any other medications. Tell your pharmacist to give you the list of Lubiprostone ingredients.

Tell your pharmacist and doctor what other medications (nonprescription and prescription), dietary supplements, herbal products, and vitamins you're using or intend to use. Make sure to name any of these:

  • Methadone (Methadose, Dolophine)
  • Medicines for high blood pressure

Your physician may need to adjust your doses of medicines or carefully check you for side effects.

Some severe side effects may occur after taking Lubiprostone, such as shortness of breath. Usually, this side effect doesn't go beyond three hours but may occur again with repeat use.

Fainting, lightheadedness, or dizziness may happen, especially when you suddenly get up from a lying/sitting position. The above symptoms are very likely to develop when you start taking Lubiprostone or if you get dehydrated. It may help to get up slowly. Additionally, lying down for some time may help relieve lightheadedness or dizziness.

Lubiprostone may cause severe diarrhea, nausea, or difficulty with breathing. If your conditions and symptoms become worse, or if they don't get better within a matter of days, see your doctor.

The FDA warns that a few patients develop difficulty with breathing (dyspnea) when taking Lubiprostone. When this occurs, patients report problems with taking a breath and chest tightness within half an hour to an hour of having their first dose.

If you've had certain intestinal or stomach problems before, particularly blockages in the bowels or stomach, liver disease, or severe diarrhea, make sure to report them to your doctor before using Lubiprostone.

Also inform your healthcare professional if you've ever had Crohn's disease, gallstones, Hirschsprung's disease, a hernia, polyps, diverticulitis, or impacted bowel movements.

Inform your healthcare professional if you have very serious liver disease or diarrhea.

If you're planning to get pregnant or are pregnant, tell your healthcare professional before you start taking Lubiprostone. Lubiprostone may affect the fetus and should be taken only when the benefits are greater than the risks. Your healthcare professional may help you make a decision if you're planning to get pregnant or if you're already pregnant.

Ask your pharmacist or doctor how you should discard any medicine you don't use.
