    Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death. PERSERIS is not approved for the treatment of patients with dementia-related psychosis and has not been studied in this population.


    PERSERIS is indicated for the treatment of schizophrenia in adults.


    PERSERIS is contraindicated in patients with a known hypersensitivity to risperidone, its metabolite, paliperidone, or to any of its components. Hypersensitivity reactions, including anaphylactic reactions and angioedema, have been reported in patients treated with risperidone or paliperidone.


    Cerebrovascular Adverse Reactions: In trials of elderly patients with dementia-related psychosis, there was a significantly higher incidence of cerebrovascular adverse reactions (e.g., stroke, transient ischemic attack), including fatalities, in patients treated with oral risperidone compared to placebo. PERSERIS is not approved for use in patients with dementia-related psychosis.

    Neuroleptic Malignant Syndrome, a potentially fatal symptom complex, has been reported with antipsychotic medications. Clinical manifestations include hyperpyrexia, muscle rigidity, altered mental status, and evidence of autonomic instability (see full Prescribing Information). Additional signs may include elevated creatine phosphokinase, myoglobinuria (rhabdomyolysis), and acute renal failure. Management should include immediate discontinuation of antipsychotic drugs and other drugs not essential to concurrent therapy, intensive symptomatic treatment and medical monitoring, and treatment of any concomitant serious medical problems.

    Tardive Dyskinesia (TD): TD may develop in patients treated with antipsychotic drugs. The risk of developing TD and likelihood that it will become irreversible are believed to increase with treatment duration and total cumulative dose. Less commonly, TD can develop after relatively brief treatment periods at low doses. Elderly patients, especially elderly women, appear to be at increased risk, but it is impossible to predict which patients will develop TD. Therefore, PERSERIS should be prescribed in a manner that is most likely to minimize the occurrence of TD. Discontinue treatment if clinically appropriate.

    Metabolic Changes that may increase cardiovascular/cerebrovascular risk, have been associated with atypical antipsychotics (APs).

    • Hyperglycemia and Diabetes Mellitus (DM), in some cases extreme and associated with ketoacidosis or hyperosmolar coma or death, have been reported in patients treated with APs, including risperidone. Patients with DM who are started on atypical APs, including PERSERIS, should be monitored regularly for worsening of glucose control. Patients at risk for DM (e.g., obesity, family history of diabetes) who are starting treatment with atypical APs, including PERSERIS, should undergo fasting blood glucose (FBG) testing at the beginning of treatment and periodically while treated. Any patient treated with atypical APs, including PERSERIS, should be monitored for symptoms of hyperglycemia including polydipsia, polyuria, polyphagia, and weakness. Patients who develop symptoms of hyperglycemia during treatment with atypical APs, including PERSERIS, should undergo FBG testing. In some cases, hyperglycemia has resolved when risperidone was discontinued; however, some patients required continuation of antidiabetic treatment despite discontinuation of risperidone.

    • Dyslipidemia has been observed in patients treated with atypical APs.

    • Weight Gain has been observed with atypical AP use. Monitoring weight is recommended.

    Hyperprolactinemia: Risperidone elevates prolactin levels, and the elevation persists during chronic administration. Risperidone is associated with higher levels of prolactin elevation than other antipsychotic agents. Hyperprolactinemia may inhibit reproductive function in female and male patients. Galactorrhea, amenorrhea, gynecomastia, and impotence have been reported in patients receiving prolactin-elevating drugs. Long-standing hyperprolactinemia, when associated with hypogonadism, may lead to decreased bone density in females and males.

    Orthostatic Hypotension: Risperidone may induce orthostatic hypotension associated with dizziness, tachycardia, and in some patients, syncope. Use with particular caution in patients with known cardiovascular disease, cerebrovascular disease, and conditions which predispose patients to hypotension, and in the elderly and patients with renal or hepatic impairment. Monitor such patients and consider a dose reduction if hypotension occurs.

    Falls: Somnolence, postural hypotension, motor instability, and sensory instability have been reported with the use of antipsychotics, including PERSERIS, which may lead to falls, and consequently, fractures or other fall-related injuries. Assess the risk of falls when initiating treatment and recurrently during treatment.

    Leukopenia, Neutropenia, and Agranulocytosis have been reported with antipsychotic agents, including risperidone. In patients with a history of a clinically significant low white blood count (WBC) or a drug-induced leukopenia/neutropenia, perform a complete blood count frequently during the first few months of therapy. Consider discontinuation at the first sign of a clinically significant decline in WBC in the absence of other causative factors. Monitor patients with clinically significant neutropenia for fever or other symptoms/signs of infection and treat promptly if such symptoms/signs occur. Discontinue PERSERIS in patients with severe neutropenia (absolute neutrophil count <1000/mm3) and follow WBC until recovery.

    Potential for Cognitive and Motor Impairment: Risperidone may impair judgment, thinking, or motor skills. Caution patients about operating machinery, including automobiles, until they are reasonably certain PERSERIS does not affect them adversely.

    Seizures have been observed in risperidone studies in adults with schizophrenia. PERSERIS should be used cautiously in patients with a history of seizures or other conditions that potentially lower the seizure threshold.

    Dysphagia: Esophageal dysmotility and aspiration can occur. Use cautiously in patients at risk for aspiration pneumonia.

    Priapism has been reported with other risperidone products. Severe priapism may require surgical intervention.

    Disruption of Body Temperature Regulation has been attributed to antipsychotic agents. Use with caution in patients who will be exposed to temperature extremes.

    Adverse Reactions:

    The most common adverse reactions in a clinical trial (≥ 5% and greater than placebo) were increased weight, constipation, sedation/somnolence, pain in extremity, back pain, akathisia, anxiety, and musculoskeletal pain. The most common injection site reactions (≥ 5%) were injection site pain and erythema. This is not a complete list of potential adverse events. Please see the full Prescribing Information for a complete list.


    • Carbamazepine and other strong CYP3A4 inducers decrease risperidone plasma concentration.

    • Fluoxetine, paroxetine, and other strong CYP2D6 inhibitors increase risperidone plasma concentration.

    • Use with other CNS drugs or alcohol may increase nervous system disorders.

    • PERSERIS may enhance hypotensive effects of hypotensive agents.

    • PERSERIS may antagonize the pharmacologic effects of dopamine agonists.


    Pregnancy: PERSERIS may cause extrapyramidal and/or withdrawal symptoms in neonates with third trimester exposure. Advise patients to notify their healthcare professional if they become or intend to become pregnant during treatment with PERSERIS. Patients exposed to PERSERIS during pregnancy may be registered with the National Pregnancy Registry for Atypical Antipsychotics (1-866-961-2388 or

    Lactation: Infants exposed to risperidone through breastmilk should be monitored for excess sedation, failure to thrive, jitteriness, and extrapyramidal symptoms.

    Pediatric Use: Safety and effectiveness of PERSERIS have not been established in pediatric patients.

    Renal or Hepatic Impairment: Carefully titrate on oral risperidone up to at least 3 mg before initiating treatment with PERSERIS at a dose of 90 mg.
