This medication is used to treat chronic constipation. It is used when other medications used to treat constipation (such as laxatives) have not provided relief. Prucalopride works by improving how well your stomach and intestines move food through the bowels during digestion.

Read the Patient Information Leaflet if available from your pharmacist before you start taking prucalopride and each time you get a refill. If you have any questions, ask your doctor or pharmacist.

Take this medication by mouth with or without food as directed by your doctor, usually once a day. The dosage is based on your age, medical condition, and response to treatment. The usual dose is 2 milligrams per day.

Use this medication regularly to get the most benefit from it. To help you remember, take it at the same time each day.

Tell your doctor if you do not get relief of constipation after 3 to 4 days. Your doctor may recommend you temporarily take additional medication (such as a stimulant laxative) along with prucalopride for fast relief of constipation. If additional medication is recommended, carefully follow your doctor's directions for use. Ask your doctor how long you should keep taking this and/or other medications for constipation.

Nausea, abdominal pain, diarrhea, or headache commonly occur during the first 1 to 2 days of treatment. Dizziness or tiredness may also occur. If any of these effects last or get worse, tell your doctor or pharmacist promptly.

Remember that this medication has been prescribed because your doctor has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
