Do not receive RISPERDAL CONSTA® if you are allergic to paliperidone, risperidone, or any of the ingredients in RISPERDAL CONSTA®.
Cerebrovascular problems (stroke) that can lead to death have been reported in elderly patients with dementia-related psychosis.
Neuroleptic Malignant Syndrome (NMS) is a rare but very serious problem that can happen in people who receive RISPERDAL CONSTA®. NMS can cause death and must be treated in a hospital. Call your healthcare provider right away if you become severely ill and have any of these symptoms: high fever, severe muscle stiffness, confusion, loss of consciousness, or changes in your breathing, heartbeat and blood pressure.
Tardive Dyskinesia (TD) is a serious, sometimes permanent side effect reported with RISPERDAL CONSTA® 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. Elderly female patients appear to be at increased risk for TD, although it is impossible to predict which patients will develop the syndrome. This condition can develop after a brief period of therapy at low doses, although this is much less common. Symptoms may go away partially or completely if therapy is stopped.
Atypical antipsychotic drugs have been associated with metabolic changes that can increase cardiovascular/cerebrovascular risks. These changes may include:
High blood sugar and diabetes have been reported with RISPERDAL CONSTA® and similar medicines. If you already have diabetes or have risk factors such as being overweight or a family history of diabetes, blood sugar testing should be done at the beginning and during the treatment. The complications of diabetes can be serious and even life-threatening. Call your healthcare professional if you develop signs of high blood sugar or diabetes, such as being thirsty all the time, having to urinate or “pass urine” more often than usual, or feeling weak or hungry.
Changes in cholesterol and triglycerides have been noted in patients taking atypical antipsychotics. Check with your healthcare professional while on treatment.
Weight gain has been reported in patients taking atypical antipsychotics. Monitor weight gain while on treatment.
RISPERDAL CONSTA® 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 problems with erection.
Some people taking RISPERDAL CONSTA® 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 can be reduced.
Patients (particularly the elderly) taking antipsychotics with certain health conditions or those on long-term therapy should be evaluated by their healthcare professional for the potential risk of falls.
Blood problems such as low numbers of white blood cells have been reported in patients taking risperidone and similar medications. In some cases it has been serious and life-threatening. Depending upon your medical condition, your healthcare professional may choose to test your blood as you start therapy with RISPERDAL CONSTA®.
