Wording differs between labels, and the full indications section on this page takes precedence when it is present.

1 INDICATIONS AND USAGE RISPERDAL is an atypical antipsychotic indicated for: Treatment of schizophrenia ( 1.1 ) As monotherapy or adjunctive therapy with lithium or valproate, for the treatment of acute manic or mixed episodes associated with Bipolar I Disorder ( 1.2 ) Treatment of irritability associated with autistic disorder ( 1.3 ) 1.1 Schizophrenia RISPERDAL (risperidone) is indicated for the treatment of schizophrenia. Efficacy was established in 4 short-term trials in adults, 2 short-term trials in adolescents (ages 13 to 17 years), and one long-term maintenance trial in adults [see Clinical Studies (14.1) ] . 1.2 Bipolar Mania Monotherapy RISPERDAL is indicated for the treatment of acute manic or mixed episodes associated with Bipolar I Disorder. Efficacy was established in 2 short-term trials in adults and one short-term trial in children and adolescents (ages 10 to 17 years) [see Clinical Studies (14.2) ] . Adjunctive Therapy RISPERDAL adjunctive therapy with lithium or valproate is indicated for the treatment of acute manic or mixed episodes associated with Bipolar I Disorder. Efficacy was established in one short-term trial in adults [see Clinical Studies (14.3) ] . 1.3 Irritability Associated with Autistic Disorder RISPERDAL is indicated for the treatment of irritability associated with autistic disorder, including symptoms of aggression towards others, deliberate self-injuriousness, temper tantrums, and quickly changing moods. Efficacy was established in 3 short-term trials in children and adolescents (ages 5 to 17 years) [see Clinical Studies (14.4) ] .

May increase to dosages above 1.5 mg twice daily at intervals of one week or longer. Recommended daily dosage: Initial Dose Target Dose Effective Dose Range Schizophrenia: adults ( 2.1 ) 2 mg 4 to 8 mg 4 to 16 mg Schizophrenia: adolescents ( 2.1 ) 0.5 mg 3 mg 1 to 6 mg Bipolar mania: adults ( 2.2 ) 2 to 3 mg 1 to 6 mg 1 to 6 mg Bipolar mania: in children and adolescents ( 2.2 ) 0.5 mg 1 to 2.5 mg 1 to 6 mg Irritability associated with autistic disorder ( 2.3 ) 0.25 mg (Weight < 20 kg) 0.5 mg (Weight ≥20 kg) 0.5 mg (<20 kg) 1 mg (≥20 kg) 0.5 to 3 mg Severe Renal or Hepatic Impairment in Adults: Use a lower starting dose of 0.5 mg twice daily. May increase to dosages above 1.5 mg twice daily at intervals of at least one week. ( 2.4 ) Oral Solution: Can be administered directly from calibrated oral dosing syringe or mixed with beverage (water, coffee, orange juice, or low-fat milk). ( 2.6 ) M-TAB Orally Disintegrating Tablets: Open the blister only when ready to administer, and immediately place tablet on the tongue. Can be swallowed with or without liquid. ( 2.7 ) 2.1 Schizophrenia Adults Usual Initial Dose RISPERDAL can be administered once or twice daily. Initial dosing is 2 mg per day. May increase the dose at intervals of 24 hours or greater, in increments of 1 to 2 mg per day, as tolerated, to a recommended dose of 4 to 8 mg per day. In some patients, slower titration may be appropriate. Efficacy has been demonstrated in a range of 4 mg to 16 mg per day. However, doses above 6 mg per day for twice daily dosing were not demonstrated to be more efficacious than lower doses, were associated with more extrapyramidal symptoms and other adverse effects, and are generally not recommended. In a single study supporting once-daily dosing, the efficacy results were generally stronger for 8 mg than for 4 mg. The safety of doses above 16 mg per day has not been evaluated in clinical trials [see Clinical Studies (14.1) ] . Adolescents The initial dose is 0.5 mg once daily, administered as a single-daily dose in the morning or evening. The dose may be adjusted at intervals of 24 hours or greater, in increments of 0.5 mg or 1 mg per day, as tolerated, to a recommended dose of 3 mg per day. Although efficacy has been demonstrated in studies of adolescent patients with schizophrenia at doses between 1 mg to 6 mg per day, no additional benefit was observed above 3 mg per day, and higher doses were associated with more adverse events. Doses higher than 6 mg per day have not been studied. Patients experiencing persistent somnolence may benefit from administering half the daily dose twice daily. Maintenance Therapy While it is unknown how long a patient with schizophrenia should remain on RISPERDAL, the effectiveness of RISPERDAL 2 mg per day to 8 mg per day at delaying relapse was demonstrated in a controlled trial in adult patients who had been clinically stable for at least 4 weeks and were then followed for a period of 1 to 2 years [see Clinical Studies (14.1) ] . Both adult and adolescent patients who respond acutely should generally be maintained on their effective dose beyond the acute episode. Patients should be periodically reassessed to determine the need for maintenance treatment. Reinitiation of Treatment in Patients Previously Discontinued Although there are no data to specifically address reinitiation of treatment, it is recommended that after an interval off RISPERDAL, the initial titration schedule should be followed. Switching From Other Antipsychotics There are no systematically collected data to specifically address switching schizophrenic patients from other antipsychotics to RISPERDAL, or treating patients with concomitant antipsychotics. 2.2 Bipolar Mania Usual Dose Adults The initial dose range is 2 mg to 3 mg per day. The dose may be adjusted at intervals of 24 hours or greater, in increments of 1 mg per day. The effective dose range is 1 mg to 6 mg per day, as studied in the short-term, placebo-controlled trials. In these trials, short-term (3 week) anti-manic efficacy was demonstrated in a flexible dosage range of 1 mg to 6 mg per day [see Clinical Studies (14.2 , 14.3) ] . RISPERDAL doses higher than 6 mg per day were not studied. Pediatrics The initial dose is 0.5 mg once daily, administered as a single-daily dose in the morning or evening. The dose may be adjusted at intervals of 24 hours or greater, in increments of 0.5 mg or 1 mg per day, as tolerated, to the recommended target dose of 1 mg to 2.5 mg per day. Although efficacy has been demonstrated in studies of pediatric patients with bipolar mania at doses between 0.5 mg and 6 mg per day, no additional benefit was observed above 2.5 mg per day, and higher doses were associated with more adverse events. Doses higher than 6 mg per day have not been studied. Patients experiencing persistent somnolence may benefit from administering half the daily dose twice daily. Maintenance Therapy There is no body of evidence available from controlled trials to guide a clinician in the longer-term management of a patient who improves during treatment of an acute manic episode with RISPERDAL. While it is generally agreed that pharmacological treatment beyond an acute response in mania is desirable, both for maintenance of the initial response and for prevention of new manic episodes, there are no systematically obtained data to support the use of RISPERDAL in such longer-term treatment (i.e., beyond 3 weeks). The physician who elects to use RISPERDAL for extended periods should periodically re-evaluate the long-term risks and benefits of the drug for the individual patient. 2.3 Irritability Associated with Autistic Disorder – Pediatrics (Children and Adolescents) The dosage of RISPERDAL should be individualized according to the response and tolerability of the patient. The total daily dose of RISPERDAL can be administered once daily, or half the total daily dose can be administered twice daily. For patients with body weight less than 20 kg, initiate dosing at 0.25 mg per day. For patients with body weight greater than or equal to 20 kg, initiate dosing at 0.5 mg per day. After a minimum of four days, the dose may be increased to the recommended dose of 0.5 mg per day for patients less than 20 kg and 1.0 mg per day for patients greater than or equal to 20 kg. Maintain this dose for a minimum of 14 days. In patients not achieving sufficient clinical response, the dose may be increased at intervals of 2 weeks or greater, in increments of 0.25 mg per day for patients less than 20 kg, or increments of 0.5 mg per day for patients greater than or equal to 20 kg. The effective dose range is 0.5 mg to 3 mg per day. No dosing data are available for children who weigh less than 15 kg. Once sufficient clinical response has been achieved and maintained, consider gradually lowering the dose to achieve the optimal balance of efficacy and safety. The physician who elects to use RISPERDAL for extended periods should periodically re-evaluate the long-term risks and benefits of the drug for the individual patient. Patients experiencing persistent somnolence may benefit from a once-daily dose administered at bedtime or administering half the daily dose twice daily, or a reduction of the dose. 2.4 Dosing in Patients with Severe Renal or Hepatic Impairment For patients with severe renal impairment (Clcr< 30 mL/min) or hepatic impairment (10–15 points on Child Pugh System), the initial starting dose is 0.5 mg twice daily. The dose may be increased in increments of 0.5 mg or less, administered twice daily. For doses above 1.5 mg twice daily, increase in intervals of one week or greater [see Use in Specific Populations (8.6 and 8.7) ]. 2.5 Dose Adjustments for Specific Drug Interactions When RISPERDAL is co-administered with enzyme inducers (e.g., carbamazepine), the dose of RISPERDAL should be increased up to double the patient's usual dose. It may be necessary to decrease the RISPERDAL dose when enzyme inducers such as carbamazepine are discontinued [see Drug Interactions (7.1) ] . Similar effect may be expected with co-administration of RISPERDAL with other enzyme inducers (e.g., phenytoin, rifampin, and phenobarbital). When fluoxetine or paroxetine is co-administered with RISPERDAL, the dose of RISPERDAL should be reduced. The RISPERDAL dose should not exceed 8 mg per day in adults when co-administered with these drugs. When initiating therapy, RISPERDAL should be titrated slowly. It may be necessary to increase the RISPERDAL dose when enzyme inhibitors such as fluoxetine or paroxetine are discontinued [see Drug Interactions (7.1) ] . 2.6 Administration of RISPERDAL Oral Solution RISPERDAL Oral Solution can be administered directly from the calibrated oral dosing syringe, or can be mixed with a beverage prior to administration. RISPERDAL Oral Solution is compatible in the following beverages: water, coffee, orange juice, and low-fat milk; it is NOT compatible with either cola or tea. 2.7 Directions for Use of RISPERDAL M-TAB Orally Disintegrating Tablets Tablet Accessing RISPERDAL M-TAB Orally Disintegrating Tablets 0.5 mg, 1 mg, and 2 mg RISPERDAL M-TAB Orally Disintegrating Tablets 0.5 mg, 1 mg, and 2 mg are supplied in blister packs of 4 tablets each.

The most common adverse reactions in clinical trials (>5% and twice placebo) were parkinsonism, akathisia, dystonia, tremor, sedation, dizziness, anxiety, blurred vision, nausea, vomiting, upper abdominal pain, stomach discomfort, dyspepsia, diarrhea, salivary hypersecretion, constipation, dry mouth, increased appetite, increased weight, fatigue, rash, nasal congestion, upper respiratory tract infection, nasopharyngitis, and pharyngolaryngeal pain. The most common adverse reactions that were associated with discontinuation from clinical trials (causing discontinuation in >1% of adults and/or >2% of pediatrics) were nausea, somnolence, sedation, vomiting, dizziness, and akathisia [see Adverse Reactions, Discontinuations Due to Adverse Reactions (6.1) ] . The data described in this section are derived from a clinical trial database consisting of 9803 adult and pediatric patients exposed to one or more doses of RISPERDAL for the treatment of schizophrenia, bipolar mania, autistic disorder, and other psychiatric disorders in pediatrics and elderly patients with dementia. Of these 9803 patients, 2687 were patients who received RISPERDAL while participating in double-blind, placebo-controlled trials. The conditions and duration of treatment with RISPERDAL varied greatly and included (in overlapping categories) double-blind, fixed- and flexible-dose, placebo- or active-controlled studies and open-label phases of studies, inpatients and outpatients, and short-term (up to 12 weeks) and longer-term (up to 3 years) exposures. Safety was assessed by collecting adverse events and performing physical examinations, vital signs, body weights, laboratory analyses, and ECGs. The most common adverse reactions in clinical trials (≥5% and twice placebo) were parkinsonism, akathisia, dystonia, tremor, sedation, dizziness, anxiety, blurred vision, nausea, vomiting, upper abdominal pain, stomach discomfort, dyspepsia, diarrhea, salivary hypersecretion, constipation, dry mouth, increased appetite, increased weight, fatigue, rash, nasal congestion, upper respiratory tract infection, nasopharyngitis, and pharyngolaryngeal pain.

Adverse Reactions Associated With Discontinuation in 2 or More RISPERDAL-Treated Adult Patients in Bipolar Mania Clinical Trials Adverse Reaction RISPERDAL 1–6 mg/day (N=448) Placebo (N=424) Parkinsonism 0.4% 0% Lethargy 0.2% 0% Dizziness 0.2% 0% Alanine aminotransferase increased 0.2% 0.2% Aspartate aminotransferase increased 0.2% 0.2% Bipolar Mania - Pediatrics In a double-blind, placebo-controlled trial 12% (13/111) of RISPERDAL-treated patients discontinued due to an adverse reaction, compared with 7% (4/58) of placebo-treated patients. The adverse reactions associated with discontinuation in more than one RISPERDAL-treated pediatric patient were nausea (3%), somnolence (2%), sedation (2%), and vomiting (2%). Autistic Disorder - Pediatrics In the two 8-week, placebo-controlled trials in pediatric patients treated for irritability associated with autistic disorder (n=156), one RISPERDAL-treated patient discontinued due to an adverse reaction (Parkinsonism), and one placebo-treated patient discontinued due to an adverse event. Dose Dependency of Adverse Reactions in Clinical Trials Extrapyramidal Symptoms Data from two fixed-dose trials in adults with schizophrenia provided evidence of dose-relatedness for extrapyramidal symptoms associated with RISPERDAL treatment. Two methods were used to measure extrapyramidal symptoms (EPS) in an 8-week trial comparing 4 fixed doses of RISPERDAL (2, 6, 10, and 16 mg/day), including (1) a Parkinsonism score (mean change from baseline) from the Extrapyramidal Symptom Rating Scale, and (2) incidence of spontaneous complaints of EPS: Table 16. Dose Groups Placebo RISPERDAL 2 mg RISPERDAL 6 mg RISPERDAL 10 mg RISPERDAL 16 mg Parkinsonism 1.2 0.9 1.8 2.4 2.6 EPS Incidence 13% 17% 21% 21% 35% Similar methods were used to measure extrapyramidal symptoms (EPS) in an 8-week trial comparing 5 fixed doses of RISPERDAL (1, 4, 8, 12, and 16 mg/day): Table 17. Dose Groups RISPERDAL 1 mg RISPERDAL 4 mg RISPERDAL 8 mg RISPERDAL 12 mg RISPERDAL 16 mg Parkinsonism 0.6 1.7 2.4 2.9 4.1 EPS Incidence 7% 12% 17% 18% 20% Dystonia Class Effect: Symptoms of dystonia, prolonged abnormal contractions of muscle groups, may occur in susceptible individuals during the first few days of treatment. Dystonic symptoms include: spasm of the neck muscles, sometimes progressing to tightness of the throat, swallowing difficulty, difficulty breathing, and/or protrusion of the tongue. While these symptoms can occur at low doses, they occur more frequently and with greater severity with high potency and at higher doses of first generation antipsychotic drugs. An elevated risk of acute dystonia is observed in males and younger age groups. Other Adverse Reactions Adverse event data elicited by a checklist for side effects from a large study comparing 5 fixed doses of RISPERDAL (1, 4, 8, 12, and 16 mg/day) were explored for dose-relatedness of adverse events. A Cochran-Armitage Test for trend in these data revealed a positive trend (p<0.05) for the following adverse reactions: somnolence, vision abnormal, dizziness, palpitations, weight increase, erectile dysfunction, ejaculation disorder, sexual function abnormal, fatigue, and skin discoloration. Changes in Body Weight Weight gain was observed in short-term, controlled trials and longer-term uncontrolled studies in adult and pediatric patients [see Warnings and Precautions (5.5) , Adverse Reactions (6) , and Use in Specific Populations (8.4) ]. Changes in ECG Parameters Between-group comparisons for pooled placebo-controlled trials in adults revealed no statistically significant differences between risperidone and placebo in mean changes from baseline in ECG parameters, including QT, QTc, and PR intervals, and heart rate. When all RISPERDAL doses were pooled from randomized controlled trials in several indications, there was a mean increase in heart rate of 1 beat per minute compared to no change for placebo patients. In short-term schizophrenia trials, higher doses of risperidone (8–16 mg/day) were associated with a higher mean increase in heart rate compared to placebo (4–6 beats per minute). In pooled placebo-controlled acute mania trials in adults, there were small decreases in mean heart rate, similar among all treatment groups. In the two placebo-controlled trials in children and adolescents with autistic disorder (aged 5 – 16 years) mean changes in heart rate were an increase of 8.4 beats per minute in the RISPERDAL groups and 6.5 beats per minute in the placebo group. There were no other notable ECG changes. In a placebo-controlled acute mania trial in children and adolescents (aged 10 – 17 years), there were no significant changes in ECG parameters, other than the effect of RISPERDAL to transiently increase pulse rate (< 6 beats per minute). In two controlled schizophrenia trials in adolescents (aged 13 – 17 years), there were no clinically meaningful changes in ECG parameters including corrected QT intervals between treatment groups or within treatment groups over time. 6.2 Postmarketing Experience The following adverse reactions have been identified during postapproval use of risperidone. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure. These adverse reactions include: alopecia, anaphylactic reaction, angioedema, atrial fibrillation, cardiopulmonary arrest, catatonia, diabetic ketoacidosis in patients with impaired glucose metabolism, dysgeusia, hypoglycemia, hypothermia, ileus, inappropriate antidiuretic hormone secretion, intestinal obstruction, jaundice, mania, pancreatitis, pituitary adenoma, precocious puberty, pulmonary embolism, QT prolongation, sleep apnea syndrome, somnambulism, Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS/TEN), sudden death, thrombocytopenia, thrombotic thrombocytopenic purpura, urinary retention, and water intoxication. Postmarketing cases of extrapyramidal symptoms (dystonia and dyskinesia) have been reported in patients concomitantly taking methylphenidate and risperidone when there was an increase or decrease in dosage, initiation, or discontinuation of either or both medications.
