Studies with risperidone and related medicines have shown that use in elderly patients with dementia has been associated with an increased rate of death.
Risperidone must be taken exactly the way the doctor has prescribed it. The physician may increase or decrease the dosage depending upon how you respond to the medicine. Risperidone may be taken with meals or between meals. Once a regular dose has been established, the total amount can be taken once a day or divided into two doses (morning and evening). Try to take risperidone at the same time every day. Risperidone should be swallowed with water or other liquid. It is important to continue taking risperidone even after the symptoms have subsided or disappeared. Do not stop taking risperidone with consulting a physician. If you take too much risperidone, immediately contact your doctor or go to the nearest hospital emergency room even if there are no signs of discomfort.
Do not be alarmed if you experience side effects from risperidone. Most side effects are mild and temporary. However do not hesitate to report all side effects to your doctor. The most common side effects of risperidone include sleeplessness/sleepiness, anxiety, trembling, muscle stiffness, restlessness, stuffed nose, increased heart rate, weight gain, constipation, and dizziness. Other side effects that may occur include agitation, difficulty breathing, headache, lightheadedness, and swelling of the ankles. Do not rise rapidly after sitting or lying for prolonged periods, especially when you start taking risperidone as dizziness may occur. Because risperidone can cause drowsiness, you should not drive or operate machinery until you are certain that you can carry on these activities. In women, risperidone can change the regularity of their monthly period or leakage of breast milk. In some men, there may be some diminished sexual function and breast enlargement may occur. In rare cases, tiredness, concentration difficulties, blurred vision, indigestion, nausea, vomiting, abdominal pain, and loss of urine can occur. In very rare cases, high blood sugar has been reported – see your doctor if you experience symptoms such as excessive thirst or urination.
Seek medical attention immediately if you experience muscle twitching or abnormal movements of the face or tongue, a sudden change in mental state or sudden weakness or numbness of the face, arms or legs, slurred speech or vision problems, or continuous erection of the penis.
If any other side effects occur while taking risperidone, contact your physician or pharmacist.

Studies in elderly patients with dementia have shown that risperidone taken by itself or with furosemide is associated with a higher rate of death. Tell your physician if you are taking furosemide prior to beginning therapy with risperidone. In elderly patients with dementia, a sudden change in mental state or sudden weakness or numbness of the face, legs or arms or instances of slurred speech have occurred. If this occurs, seek medical attention immediately. It is important for the doctor to have all the information regarding a patient prior to prescribing risperidone. The safety of this medicine in children under the age of 18 has not been established.
Risperidone can increase the effect of alcohol, tranquilizers, narcotics, antihistamines and certain antidepressants. Do not drink alcohol while taking risperidone.

Other interactions exist so it is important to tell your dentist, doctor and other health care professionals that you are being treated with risperidone.
