Why is this medication prescribed?

Psyllium, a bulk-forming laxative, is used to treat constipation. It absorbs liquid in the intestines, swells, and forms a bulky stool, which is easy to pass.

This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.

How should this medication be used?

Psyllium comes as a powder, granules, and wafer to take by mouth. It usually is taken one to three times daily. Follow the directions on the package or on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take psyllium exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.

The powder and granules must be mixed with 8 ounces (240 milliliters) of a pleasant tasting liquid, such as fruit juice, right before use. Chew wafers thoroughly. For psyllium to work properly and to prevent side effects, you must drink at least 8 ounces (240 milliliters) of liquid when you take it.

Do not take psyllium for longer than 1 week unless your doctor tells you to.

Are there other uses for this medicine?

Your doctor also may prescribe psyllium to treat diarrhea or high cholesterol. Talk to your doctor about the possible risks of using this drug for your condition.
