You may need to gradually reduce the dose. Only stop taking risperidone on your prescriber's advice.
If you notice an increased hunger or thirst, different from your normal hunger or thirst, or if you find that you must frequently use the restroom (excessive urination), you should contact your health care provider as soon as possible. You may need to have your blood sugar monitored.
You may get dizzy or drowsy. Do not drive, use machinery, or do anything that needs mental alertness until you know how risperidone affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells. Alcohol can increase dizziness and drowsiness. Avoid alcoholic drinks.

Do not treat yourself for colds, diarrhea or allergies. Ask your prescriber or health care professional for advice, some nonprescription medicines may increase possible side effects.
