The most common adverse reactions observed in all clinical trials

with RISPERDAL occurring at a rate of at least 10% were somnolence,

increased appetite, fatigue, rhinitis, upper respiratory tract

infection, vomiting, coughing, urinary incontinence, increased

saliva, constipation, fever, tremors, muscle stiffness, abdominal

pain, anxiety, nausea, dizziness, dry mouth, rash, restlessness, and

indigestion.

Neuroleptic Malignant Syndrome (NMS) is a rare and potentially fatal

side effect reported with RISPERDAL and similar medicines. Call your

doctor immediately if the person being treated develops symptoms such

as high fever; stiff muscles; shaking; confusion; sweating; changes

in pulse, heart rate, or blood pressure; or muscle pain and weakness.

Treatment should be stopped if the person being treated has NMS.

Tardive Dyskinesia (TD) is a serious, sometimes permanent side effect

reported with RISPERDAL and similar medications. TD includes

uncontrollable movements of the face, tongue, and other parts of the

body. The risk of developing TD and the chance that it will become

permanent is thought to increase with the length of therapy and the

overall dose taken by the patient. This condition can develop after a

brief period of therapy at low doses, although this is much less

common. There is no known treatment for TD, but it may go away

partially or completely if therapy is stopped.

RISPERDAL and similar medications can raise the blood levels of a

hormone known as prolactin, causing a condition known as

hyperprolactinemia. Blood levels of prolactin remain elevated with

continued use. Some side effects seen with these medications include

the absence of a menstrual period; breasts producing milk; the

development of breasts by males; and the inability to achieve an

erection. The connection between prolactin levels and side effects is

unknown.

High blood sugar and diabetes have been reported with RISPERDAL and

similar medications. If the person being treated has diabetes or risk

factors such as being overweight or a family history of diabetes,

blood sugar testing should be performed at the beginning and

throughout treatment. Complications of diabetes can be serious and

even life threatening. If signs of high blood sugar or diabetes

develop, such as being thirsty all the time, going to the bathroom a

lot, or feeling weak or hungry, contact your doctor.

RISPERDAL should be used cautiously in people with a seizure

disorder, who have had seizures in the past, or who have conditions

that increase their risk for seizures.

Some people taking RISPERDAL may feel faint or lightheaded when they

stand up or sit up too quickly. By standing up or sitting up slowly

and following your healthcare professional's dosing instructions,

this side effect may be reduced or it may go away over time.

Extrapyramidal Symptoms (EPS) are usually persistent movement

disorders or muscle disturbances, such as restlessness, tremors, and

muscle stiffness. If you observe any of these symptoms, talk to your

healthcare professional.

Some medications interact with RISPERDAL. Please inform your

healthcare professional of any medications or supplements that you

are taking. Avoid alcohol while taking RISPERDAL.

Inform your healthcare professional if you are pregnant or if you are

planning to get pregnant while taking RISPERDAL. Do not breast-feed

if you are taking RISPERDAL.

RISPERDAL may affect your driving ability; therefore, do not drive or

operate machinery before talking to your healthcare professional.

RISPERDAL may affect alertness and motor skills; use caution until

the effect of RISPERDAL is known.
