Precautions

It is very important that your doctor check your or your child's progress at regular visits to make sure this medicine is working properly. Blood tests may be needed to check for unwanted effects.

Check with your doctor right away if you or your child have any of the following symptoms while using this medicine: convulsions (seizures), difficulty with breathing, a fast heartbeat, a high fever, high or low blood pressure, increased sweating, loss of bladder control, severe muscle stiffness, unusually pale skin, or tiredness. These could be symptoms of a serious condition called neuroleptic malignant syndrome (NMS).

This medicine may cause tardive dyskinesia (a movement disorder). Check with your doctor right away if you or your child have any of the following symptoms while using this medicine: lip smacking or puckering, puffing of the cheeks, rapid or worm-like movements of the tongue, uncontrolled chewing movements, or uncontrolled movements of the arms and legs.

This medicine may increase the amount of sugar in your blood. Check with your doctor right away if you or your child have increased thirst or increased urination. If you have diabetes, you may notice a change in the results of your urine or blood sugar tests. If you have any questions, check with your doctor.

Dizziness, lightheadedness, or fainting may occur, especially when you get up suddenly from a lying or sitting position. Getting up slowly may help. If the problem continues or gets worse, check with your doctor.

Risperidone can temporarily lower the number of white blood cells in your blood, increasing the chance of getting an infection. If you can, avoid people with infections. Check with your doctor immediately if you think you are getting an infection or if you get a fever or chills, cough or hoarseness, lower back or side pain, or painful or difficult urination.

This medicine may cause drowsiness, trouble with thinking, or trouble with controlling body movements, which may lead to falls, fractures or other injuries. Do not drive or do anything else that could be dangerous until you know how this medicine affects you.

This medicine may make it more difficult for your body to cool itself down. Use care not to become overheated during exercise or hot weather since overheating may result in heat stroke. Also, use extra care not to become too cold while you are taking risperidone (the active ingredient contained in Rykindo) If you become too cold, you may feel drowsy, confused, or clumsy.

This medicine may increase your or your child's weight. Your doctor may need to check your or your child's weight on a regular basis while using this medicine.

Do not Stop taking risperidone without first checking with your doctor. Your doctor may want you to gradually reduce the amount you are taking before stopping it completely. This is to prevent side effects and to keep your condition from becoming worse.

Check with your doctor before using this medicine with alcohol or other medicines that affect the central nervous system (CNS). The use of alcohol or other medicines that affect the CNS with risperidone may worsen the side effects of this medicine, such as dizziness, poor concentration, drowsiness, unusual dreams, and trouble with sleeping. Some examples of medicines that affect the CNS are antihistamines or medicine for allergies or colds, sedatives, tranquilizers, or sleeping medicines, medicine for depression, medicine for anxiety, prescription pain medicine or narcotics, medicine for attention deficit and hyperactivity disorder, medicine for seizures or barbiturates, muscle relaxants, or anesthetics, including some dental anesthetics.

This medicine may increase prolactin blood levels if used for a long time. Check with your doctor if you have breast swelling or soreness, unusual breast milk production, absent, missed, or irregular menstrual periods, stopping of menstrual bleeding, loss in sexual ability, desire, drive, or performance, decreased interest in sexual intercourse, or an inability to have or keep an erection.

If you plan to have children, talk with your doctor before using this medicine. Some women using this medicine have become infertile (unable to have children).

Do not take other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.

In randomized placebo-controlled trials in elderly patients with dementia-related psychosis, cerebrovascular adverse events occurred more frequently in patients treated with atypical antipsychotics than those receiving placebo.

The mechanism for this risk is unknown. The risk for a cerebrovascular event was significantly higher in patients with mixed or vascular type dementia compared with Alzheimer's dementia.^[Ref]

Risperidone is associated with higher levels of prolactin elevation than other antipsychotic drugs. Hyperprolactinemia may suppress hypothalamic gonadotropin-releasing hormone (GnRH) resulting in reduced pituitary gonadotropin secretion and in turn inhibit reproductive function by impairing gonadal steroidogenesis. Galactorrhea, amenorrhea, gynecomastia, and impotence have been reported in patients receiving prolactin-elevating compounds.^[Ref]

Collective data gathered from 17 placebo-controlled clinical studies (n=5106) involving the use of atypical antipsychotic agents, including risperidone, for the treatment of behavioral disorders in the elderly patient with dementia showed a risk of death 1.6 to 1.7 times greater in the drug- treated patient than in the placebo- treated patient. The average length of duration for the trials was 10 weeks with the cause of death in the majority of cases, though not all, reported as either cardiovascular (e.g., heart failure, sudden death) or infectious (e.g., pneumonia) in nature. Similar results (i.e., increased risk of mortality with atypical antipsychotics) were reported in another meta-analysis involving elderly dementia patients that consisted of 15 randomized, placebo-controlled trials (n=3353) of 10 to 12 weeks in duration. Risperidone is not approved by the FDA for use in the treatment of behavioral disorders in elderly patients with dementia. However, in contrast, the results of another meta-analysis of 6 randomized, double-blind, placebo-controlled, clinical trials (n=1721) found a nonsignificant increase in overall mortality in elderly dementia patients treated with risperidone.

The results of a large retrospective cohort study appear to indicate that atypical antipsychotic agents (i.e., risperidone, olanzapine, clozapine, quetiapine) increase the risk of venous thromboembolism in elderly patients; however, these events seem to be rare.

Based on data from four placebo controlled trials conducted in elderly patients (n=1230), cerebrovascular adverse events (e.g., stroke, transient ischemic attack), including fatalities, have been reported in elderly patients with dementia- related psychosis. In placebo controlled trials, there was a significantly higher incidence of cerebrovascular adverse events in patients treated with risperidone compared to patients treated with placebo. Risperidone has not been shown to be safe or effective in the treatment of patients with dementia- related psychosis. Additional information on these and other clinical trials conducted in elderly patients can be obtained by calling 1-800- JANSSEN (800-526-7736). However, the association between the use of atypical antipsychotics (i.e., risperidone, olanzapine) and the risk of cerebrovascular events appears to be somewhat controversial. The results of a case-control study found no increased risk of cerebrovascular events in elderly patients treated with atypical antipsychotics.^[Ref]
