Why is Risperdal prescribed?
Risperdal is used to treat psychotic disorders and symptoms such as hallucinations, delusions, and hostility.
Risperidone is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
How should Risperdal be used?
Risperdal comes as a tablet to take by mouth. It usually is taken twice a day (every 12 hours). Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take Risperidone exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor. Continue to take Risperidone even if you feel well. Do not stop taking Risperdal without talking to your doctor, especially if you have taken large doses for a long time. Your doctor probably will decrease your dose gradually. Risperidone must be taken regularly for a few weeks before its full effect is felt.
What special precautions should I follow?
Before taking Risperdal, tell your doctor and pharmacist if you are allergic to Risperdal or any other drugs.
- tell your doctor and pharmacist what prescription and nonprescription medications you are taking, especially carbamazepine (Tegretol), clozapine (Clorazil), levodopa (Dopar, Sinemet), medications for high blood pressure, and vitamins.
- tell your doctor if you have or have ever had heart, kidney, or liver disease; angina, irregular heartbeat, or problems with your blood pressure; stroke; seizures; blood disorders; depression; or a history of alcohol or drug abuse.
- tell your doctor if you are pregnant, plan to become pregnant, or are breast-feeding. If you become pregnant while taking Risperdal, call your doctor.
- if you are having surgery, including dental surgery, tell the doctor or dentist that you are taking Risperdal.
- you should know that Risperidone may make you drowsy. Do not drive a car or operate machinery until you know how this drug affects you.
- remember that alcohol can add to the drowsiness caused by Risperidone.
- plan to avoid unnecessary or prolonged exposure to sunlight and to wear protective clothing, sunglasses, and sunscreen. Risperdal may make your skin sensitive to sunlight.
What should I do if I forget a dose?
Take the missed dose as soon as you remember it. However, if it is almost time for the next dose, skip the missed dose and continue your regular dosing schedule. Do not take a double dose to make up for a missed one.
