Dose can be reduced to 300 mg in patients with adverse reactions ( 2.2 ) There are two ways to initiate treatment with ABILIFY MAINTENA 1-day initiation: Administer two separate intramuscular injections of ABILIFY MAINTENA 400 mg and a single oral dose of aripiprazole 20 mg ( 2.2 ) 14-day initiation: In conjunction with first ABILIFY MAINTENA 400 mg dose, take 14 consecutive days of concurrent oral aripiprazole (10 mg to 20 mg) or current oral antipsychotic ( 2.2 ) Dosage adjustments are required for missed doses ( 2.3 ) Known CYP2D6 poor metabolizers: Recommended starting and maintenance dose is 300 mg administered monthly as a single injection ( 2.4 ) See full prescribing information for ABILIFY MAINTENA dosage modifications due to drug interactions ( 2.4 ). ABILIFY MAINTENA comes in two types of kits. See instructions for reconstitution/injection/disposal procedures for 1) Pre-filled Dual Chamber Syringe ( 2.6 ), and 2) Vials ( 2.7 ). 2.1 Important Administration Information For patients who have never taken aripiprazole, establish tolerability with oral aripiprazole prior to initiating treatment with ABILIFY MAINTENA. Due to the half-life of oral aripiprazole (i.e., 75 hours and 94 hours for aripiprazole and dehydro-aripiprazole, respectively), it may take up to 2 weeks to fully assess tolerability. ABILIFY MAINTENA must be administered by intramuscular injection by a healthcare professional. Do not administer by any other route. For detailed preparation and administration instructions, [see Dosage and Administration (2.6 , 2.7) ] . 2.2 Recommended Dosage for ABILIFY MAINTENA The recommended dose of ABILIFY MAINTENA is 400 mg monthly (no sooner than 26 days after the previous injection). There are two ways to initiate treatment with ABILIFY MAINTENA in patients receiving oral antipsychotics: 1-day initiation: Administer two intramuscular injections of ABILIFY MAINTENA 400 mg in two different injection sites (in either the deltoid or gluteal muscle), and one dose of oral aripiprazole 20 mg on the first day of treatment with ABILIFY MAINTENA. Do not administer both injections into the same muscle. 14-day initiation: When ABILIFY MAINTENA injection is initiated in patients receiving oral aripiprazole administer one intramuscular injection of ABILIFY MAINTENA 400 mg in either the deltoid or gluteal muscle and continue treatment with oral aripiprazole (10 mg to 20 mg) for 14 consecutive days to achieve therapeutic aripiprazole concentrations during initiation of therapy. For patients already stable on another oral antipsychotic (and known to tolerate aripiprazole), administer one intramuscular injection of ABILIFY MAINTENA 400 mg in either the deltoid or gluteal muscle and continue treatment with the oral antipsychotic for 14 consecutive days to maintain therapeutic antipsychotic concentrations during initiation of therapy. If there are adverse reactions with the 400 mg dosage, the dosage may be reduced to 300 mg once monthly. 2.3 Missed Doses If the second or third doses are missed: If more than 4 weeks and less than 5 weeks have elapsed since the last injection, administer the injection as soon as possible . If more than 5 weeks have elapsed since the last injection, restart treatment with either 1-day initiation or 14-day initiation with ABILIFY MAINTENA [see Dosage and Administration (2.2) ] . If the fourth or subsequent doses are missed: If more than 4 weeks and less than 6 weeks have elapsed since the last injection, administer the injection as soon as possible. If more than 6 weeks have elapsed since the last injection, restart treatment with either 1-day initiation or 14-day initiation with ABILIFY MAINTENA [see Dosage and Administration (2.2) ] . 2.4 Dosage Modifications for Cytochrome P450 Considerations Refer to Table 1 and Table 2 for dosage modifications for patients who are CYP2D6 poor metabolizers and/or in patients taking concomitant CYP3A4 inhibitors or CYP2D6 inhibitors for greater than 14 days. If the CYP3A4 inhibitor or CYP2D6 inhibitor is withdrawn, the ABILIFY MAINTENA dosage may need to be increased to the previous dose [see Dosage and Administration (2.2) ] . Avoid the concomitant use of CYP3A4 inducers with ABILIFY MAINTENA for greater

Monitoring
- • 5 WARNINGS AND PRECAUTIONS Cerebrovascular Adverse Reactions in Elderly Patients with Dementia-Related Psychosis: Increased incidence of cerebrovascular adverse reactions (e.g., stroke, transient ischemic attack, including fatalities) ( 5.2 ) Neuroleptic Malignant Syndrome: Manage with immediate discontinuation and close monitoring ( 5.3 ) Tardive Dyskinesia: Discontinue if clinically appropriate ( 5.4 ) Metabolic Changes: Atypical antipsychotic drugs have been associated with metabolic changes that may increase cardiovascular/cerebrovascular risk.
- • These metabolic changes include hyperglycemia, dyslipidemia, and weight gain ( 5.5 ) – Hyperglycemia and Diabetes Mellitus: Monitor patients for symptoms of hyperglycemia including polydipsia, polyuria, polyphagia, and weakness.
- • Monitor glucose regularly in patients with and at risk for diabetes ( 5.5 ) – Dyslipidemia: Undesirable alterations have been observed in patients treated with atypical antipsychotics ( 5.5 ) – Weight Gain: Gain in body weight has been observed; clinical monitoring of weight is recommended ( 5.5 ) Pathological Gambling and Other Compulsive Behaviors: Consider dose reduction or discontinuation ( 5.6 ) Orthostatic Hypotension: Use with caution in patients with known cardiovascular or cerebrovascular disease ( 5.7 ) Leukopenia, Neutropenia, and Agranulocytosis: Perform complete blood counts in patients with a history of a clinically significant low white blood cell count (WBC)/absolute neutrophil count (ANC).
- • Consider discontinuation if clinically significant decline in WBC/ANC in the absence of other causative factors ( 5.9 ) Seizures: Use cautiously in patients with a history of seizures or with conditions that lower the seizure threshold ( 5.10 ) Potential for Cognitive and Motor Impairment: Use caution when operating machinery ( 5.11 ) 5.1 Increased Mortality in Elderly Patients with Dementia- Related Psychosis Elderly patients with dementia-related psychosis treated with antipsychotic drugs are at an increased risk of death.
Interaction Notes
- • 7 DRUG INTERACTIONS CYP2D6 inhibitors and CYP3A4 Inhibitors : See full prescribing information for ABILIFY MAINTENA dosage modifications when used concomitantly with CYP2D6 inhibitors and/or CYP3A4 inhibitors for greater than 14 days ( 7.1 ) CYP3A4 Inducers : Avoid concomitant use for greater than 14 days ( 7.1 ) See full prescribing information for additional clinically significant drug interactions ( 7.1 ) 7.1 Drugs Having Clinically Important Interactions with ABILIFY MAINTENA Table 9: Clinically Important Drug Interactions with ABILIFY MAINTENA: Concomitant Drug Name or Drug Class Clinical Rationale Clinical Recommendation Strong CYP3A4 Inhibitors (e.g., ketoconazole) or strong CYP2D6 inhibitors (e.g., paroxetine, fluoxetine) The concomitant use of oral aripiprazole with strong CYP3A4 or CYP2D6 inhibitors increased the exposure of aripiprazole [see Clinical Pharmacology (12.3) ].
- • With concomitant use of ABILIFY MAINTENA with a strong CYP3A4 inhibitor or CYP2D6 inhibitor for more than 14 days, reduce the ABILIFY MAINTENA dosage [see Dosage and Administration (2.4) ].
- • Strong CYP3A4 Inducers (e.g., carbamazepine) The concomitant use of oral aripiprazole and carbamazepine decreased the exposure of aripiprazole [see Clinical Pharmacology (12.3) ].
- • Avoid use of ABILIFY MAINTENA in combination with carbamazepine and other inducers of CYP3A4 for greater than 14 days [see Dosage and Administration (2.4) ] .
