2 DOSAGE AND ADMINISTRATION Establish tolerability with oral risperidone prior to initiating treatment with RYKINDO . ( 2.1 ) Administer RYKINDO by intramuscular (IM) injection in the gluteal muscle by a healthcare provider. Do not administer by any other route. ( 2.1 ) Recommended dosage of RYKINDO is 25 mg intramuscular (IM) every 2 weeks. Patients not responding to 25 mg may benefit from 37.5 mg or 50 mg. Dosage titration should not be made more frequently than every 4 weeks. The maximum recommended dosage should not exceed 50 mg every 2 weeks. ( 2.2 , 2.3 ) Administer the first dose of RYKINDO along with 7 days of oral risperidone. ( 2.2 , 2.3 ) Renal or Hepatic Impairment: Titrate with oral risperidone up to at least 2 mg prior to initiating treatment with RYKINDO. ( 2.6 ) See Full Prescribing Information for important preparation and administration instructions. ( 2.8 ) 2.1 General Administration Information For patients who have never taken oral risperidone, establish tolerability with oral risperidone prior to initiating RYKINDO. RYKINDO should be administered every 2 weeks by intramuscular (IM) gluteal injection. Each injection should be administered by a health care professional. Do not administer by any other route. Alternate injections between the two buttocks. Do not combine two different dose strengths of RYKINDO in a single administration. For detailed preparation and administration instructions, see Dosage and Administration (2.8) . 2.2 Dosage Recommendations for the Treatment of Schizophrenia The recommended dosage of RYKINDO for the treatment of schizophrenia is 25 mg every 2 weeks. Administer the first dose of RYKINDO along with 7 days of oral risperidone. Patients not responding to 25 mg may benefit from a higher dose of 37.5 mg or 50 mg. The maximum dose should not exceed 50 mg every 2 weeks. No additional benefit was observed with dosages greater than 50 mg of risperidone long-acting injection (intramuscular); however, a higher incidence of adverse reactions was observed. Dose titration should not be made more frequently than every 4 weeks. 2.3 Dosage Recommendations for Maintenance Treatment of Bipolar I Disorder The recommended dosage of RYKINDO for monotherapy or adjunctive therapy to lithium or valproate for the maintenance treatment of bipolar I disorder is 25 mg every 2 weeks. Administer the first dose of RYKINDO along with 7 days of oral risperidone. Some patients may benefit from a higher dose of 37.5 mg or 50 mg. Dosages above 50 mg have not been studied in this population. Dose titration should not be made more frequently than every 4 weeks. 2.4 Patients Currently Receiving Risperidone Long-acting Injection 2-week Intramuscular Formulation (e.g., Risperdal Consta) The RYKINDO dose for patients receiving a risperidone long-acting injection (intramuscular) every two week formulation (e.g., Risperdal Consta) should be the same as that of the previous treatment. The first injection of RYKINDO should be given 4 weeks (no later than 5 weeks) after the last injection of the previous treatment. Supplementation with oral risperidone is not recommended [see Clinical Pharmacology (12.3) ] . Titration should not be made more frequently than every 4 weeks. 2.5 Reinitiation of Treatment in Patients Previously Discontinued There are no data to specifically address reinitiation of treatment. When restarting patients who have had an interval off treatment with RYKINDO, the previously established dosage should be reinitiated if there has been no change in the patient's general medical condition. Supplementation with oral risperidone is also required. 2.6 Dosage Recommendations for Patients with Renal or Hepatic Impairment Patients with renal or hepatic impairment should be treated with titrated oral risperidone prior to initiating treatment with RYKINDO [see Use in Specific Populations (8.6 , 8.7) and Clinical Pharmacology (12.3) ] . The recommended starting dose is 0.5 mg oral risperidone twice daily during the first week, which can be increased to 1 mg twice daily or 2 mg once daily during the second week. If a total daily dose of at least 2 mg oral risperidone is well tolerated, RYKINDO 25 mg can be administered every 2 weeks with oral supplementation for 7 days following the first injection [see Dosing and Administration (2.2 , 2.3) ] . In some patients, slower titration may be appropriate. 2.7 Dosage Recommendations for Concomitant Use of RYKINDO with Strong CYP2D6 Inhibitors and Strong CYP3A4 Inducers Co-administration of carbamazepine and other CYP3A4 enzyme inducers (e.g., phenytoin, rifampin, phenobarbital) with risperidone would be expected to cause decreases in the plasma concentrations of the sum of risperidone and 9-hydroxyrisperidone combined, which could lead to decreased efficacy of RYKINDO treatment. The risperidone dose needs to be titrated accordingly for patients receiving these enzyme inducers, especially during initiation or discontinuation of therapy with these inducers [see Drug Interactions (7.1) ]. At the initiation of therapy with carbamazepine or other known CYP3A4 hepatic enzyme inducers, patients should be closely monitored during the first 1 to 2 months because the dose of RYKINDO may need to be adjusted. A dose increase, or additional oral risperidone, needs to be considered. On discontinuation of carbamazepine or other CYP3A4 hepatic enzyme inducers, the dosage of RYKINDO should be re-evaluated and, if necessary, decreased. Patients may be placed on a lower dose of RYKINDO between 2 to 4 weeks before the planned discontinuation of carbamazepine or other CYP3A4 inducers to adjust for the expected increase in plasma concentrations of risperidone plus 9-hydroxyrisperidone. For patients treated with the recommended dose of 25 mg RYKINDO and discontinuing from carbamazepine or other CYP3A4 enzyme inducers, it is recommended to continue treatment with the 25-mg dose unless clinical judgment necessitates either lowering the dose to 12.5 mg, in which case a different risperidone long-acting injection intramuscular formulation should be used, or interruption of RYKINDO treatment. Fluoxetine and paroxetine, CYP2D6 inhibitors, have been shown to increase the plasma concentration of risperidone by 2.5 to 2.8-fold and 3 to 9-fold, respectively. Fluoxetine did not affect the plasma concentration of 9-hydroxyrisperidone. Paroxetine lowered the concentration of 9-hydroxyrisperidone by about 10%. The dose of risperidone needs to be titrated accordingly when co-administering fluoxetine or paroxetine. When either concomitant fluoxetine or paroxetine is initiated or discontinued, the physician should re-evaluate the dose of RYKINDO. When initiation of fluoxetine or paroxetine is considered, patients may be placed on a lower dose of RYKINDO between 2 to 4 weeks before the planned start of fluoxetine or paroxetine therapy to adjust for the expected increase in plasma concentrations of risperidone. When fluoxetine or paroxetine is initiated in patients receiving the recommended dose of 25 mg RYKINDO it is recommended to continue treatment with the 25 mg dose unless clinical judgment necessitates either lowering the dose to 12.5 mg, in which case a different risperidone long-acting injection intramuscular formulation should be used, or interruption of RYKINDO treatment. The effects of discontinuation of concomitant fluoxetine or paroxetine therapy on the pharmacokinetics of risperidone and 9-hydroxyrisperidone have not been studied [see Drug Interactions (7.1) ]. 2.8 Preparation and Administration Instructions Read the instructions for preparation and administration below and consider referring to the separate Healthcare Provider "Instructions for Use" for additional preparation and administration considerations. For gluteal intramuscular injection only. Do not inject by any other route. Alternate injections between the two buttocks.

The safety of RYKINDO for the treatment of schizophrenia in adults and as monotherapy or as adjunctive therapy to lithium or valproate for the maintenance treatment of Bipolar I Disorder in adults is based on adequate and well-controlled studies of risperidone long-acting injection (intramuscular). The data described in this section are derived from a clinical trial database consisting of 2,392 patients exposed to one or more doses of risperidone long-acting injection (intramuscular) for the treatment of schizophrenia. Of these 2,392 patients, 332 patients received risperidone long-acting injection (intramuscular) while participating in a 12-week double-blind, placebo-controlled trial. Two hundred two (202) of the 332 were patients with schizophrenia who received 25 mg or 50 mg risperidone long-acting injection (intramuscular). The conditions and duration of treatment with risperidone long-acting injection (intramuscular) in the other clinical trials 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 4 years) exposures. In addition to the studies in patients with schizophrenia, safety data are presented from a trial assessing the efficacy and safety of risperidone long-acting injection (intramuscular) when administered as monotherapy for maintenance treatment in patients with bipolar I disorder. Safety data are also presented from a trial assessing the efficacy and safety of risperidone long-acting injection (intramuscular) administered as adjunctive maintenance treatment in patients with bipolar disorder (intramuscular). The most common adverse reactions in clinical trials of risperidone long-acting injection (intramuscular) in patients with schizophrenia (≥ 5%) were headache, parkinsonism, dizziness, akathisia, fatigue, constipation, dyspepsia, sedation, weight increased, pain in extremity, and dry mouth. The most common adverse reactions in the double-blind, placebo-controlled periods of the bipolar disorder trials of risperidone long-acting injection (intramuscular) were weight increased (5% in the monotherapy trial) and tremor and parkinsonism (≥ 10% in the adjunctive treatment trial). Table 4 lists the adverse reactions reported in 2% or more of risperidone long-acting injection-treated patients with schizophrenia in one 12-week double-blind, placebo-controlled trial. Table 4.

Schizophrenia Approximately 11% (22/202) of risperidone long-acting (intramuscular)-treated patients in the 12-week double-blind, placebo-controlled schizophrenia trial discontinued treatment due to an adverse reaction, compared with 13% (13/98) who received placebo. The adverse reactions associated with discontinuation in two or more risperidone long-acting injection (intramuscular)-treated patients were agitation (3%), depression (2%), anxiety (1%), and akathisia (1%). Bipolar Disorder In the 24-month double-blind, placebo-controlled treatment period of the trial assessing the efficacy and safety of risperidone long-acting injection (intramuscular) monotherapy for maintenance treatment in patients with bipolar I disorder, 1 (0.6%) of 154 risperidone long-acting injection (intramuscular)-treated patients discontinued due to an adverse reaction (hyperglycemia). In the 52-week double-blind phase of the placebo-controlled trial in which risperidone long-acting injection (intramuscular) was administered as adjunctive therapy to patients with bipolar disorder in addition to continuing with their usual treatment, approximately 4% (3/72) of risperidone long-acting injection (intramuscular)-treated patients discontinued treatment due to an adverse event, compared with 1.5% (1/67) of placebo-treated patients. Adverse reactions associated with discontinuation in risperidone long-acting injection(intramuscular)-treated patients were hypokinesia (one patient) and tardive dyskinesia (one patient). Dose Dependency of Adverse Reactions in Clinical Trials Extrapyramidal Symptoms (EPS) Two methods were used to measure EPS in the 12-week double-blind, placebo-controlled trial comparing three doses of risperidone long-acting injection (intramuscular) (25 mg, 50 mg, and 75 mg) with placebo in patients with schizophrenia: (1) the incidence of spontaneous reports of EPS symptoms; and (2) the change from baseline to endpoint on the total score (sum of the subscale scores for parkinsonism, dystonia, and dyskinesia) of the Extrapyramidal Symptom Rating Scale (ESRS). The overall incidence of EPS-related adverse reactions (akathisia, dystonia, parkinsonism, and tremor) in patients treated with 25 mg risperidone long-acting injection (intramuscular)was comparable to that of patients treated with placebo; the incidence of EPS-related adverse reactions was higher in patients treated with 50 mg risperidone long-acting injection (intramuscular) ( Table 4 ). The median change from baseline to endpoint in total ESRS score showed no worsening in patients treated with risperidone long-acting injection (intramuscular) compared with patients treated with placebo: 0 (placebo group); -1 (25-mg group, significantly less than the placebo group); and 0 (50-mg group). Dystonia Symptoms of dystonia, prolonged abnormal contractions of muscle groups, may occur in susceptible individuals during the first few days of treatment. Dystonic symptoms include neck muscle spasms, 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. Changes in ECG The ECGs of 202 patients with schizophrenia treated with 25 mg or 50 mg risperidone long-acting injection (intramuscular) and 98 schizophrenic patients treated with placebo in the 12-week double-blind, placebo-controlled trial were evaluated. There were no statistically significant differences in QTc intervals (using Fridericia's and linear correction factors) during treatment with either risperidone long-acting injection (intramuscular)or placebo. The ECGs of 227 patients with Bipolar I Disorder were evaluated in the 24-month double-blind, placebo-controlled period. There were no clinically relevant differences in QTc intervals (using Fridericia's and linear correction factors) during treatment with risperidone long-acting injection (intramuscular) compared to placebo. The ECGs of 85 patients with bipolar disorder were evaluated in the 52-week double-blind, placebo-controlled trial. There were no statistically significant differences in QTc intervals (using Fridericia's and linear correction factors) during adjunctive treatment with either risperidone long-acting injection (intramuscular) (25 mg, 37.5 mg, or 50 mg) or placebo in addition to treatment as usual. Pain Assessment and Local Injection Site Reactions The mean intensity of injection pain reported by patients with schizophrenia using a visual analog scale (0 = no pain to 100 = unbearably painful) decreased in all treatment groups from the first to the last dose of risperidone long-acting injection (intramuscular) (placebo: 16.7 to 12.6; 25 mg: 12.0 to 9.0; 50 mg: 18.2 to 11.8). After the sixth injection (Week 10), investigator ratings indicated that 1% of patients treated with 25 mg or 50 mg risperidone long-acting injection (intramuscular) experienced redness, swelling, or induration at the injection site. 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of risperidone. Because these reactions are reported voluntarily from a population of uncertain size, it is not possible to reliably estimate their frequency or establish causal relationship to a drug exposure.
