Dosage and Administration ( 2.1 , 2.2 , 2.3 , 2.4 , 2.5 ) 3/2025 Warning and Precautions ( 5.11 ) 3/2025

1 INDICATIONS AND USAGE ABILIFY MAINTENA (aripiprazole) is indicated: for the treatment of schizophrenia in adults for maintenance monotherapy treatment of bipolar I disorder in adults ABILIFY MAINTENA is an atypical antipsychotic indicated: for treatment of schizophrenia in adults ( 1 ) for maintenance monotherapy treatment of bipolar I disorder in adults ( 1 )

2 DOSAGE AND ADMINISTRATION Only to be administered by intramuscular injection in the deltoid or gluteal muscle by a healthcare professional ( 2.1 ) For patients naïve to aripiprazole, establish tolerability with oral aripiprazole prior to initiating ABILIFY MAINTENA ( 2.1 ) Recommended dosage is 400 mg administered monthly as a single injection. 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 in …

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) ] . Antihypertensive Drugs Due to its alpha-adrenergic antagonism, aripiprazole has the potential to enhance the effect of certain antihypertensive agents. Monitor blood pressure and adjust dose accordingly [see Warnings and Precautions (5.7) ]. Benzodiazepines (e.g., lorazepam) The intensity of sedation was greater with the combination of oral aripiprazole and lorazepam as compared to that observed with aripiprazole alone. The orthostatic hypotension observed was greater with the combination as compared to that observed with lorazepam alone [see Warnings and Precautions (5.7) ]. Monitor sedation and blood pressure. Adjust dose accordingly. 7.2 Drugs Having No Clinically Important Interactions with ABILIFY MAINTENA Based on pharmacokinetic studies with oral aripiprazole, no dosage adjustment of ABILIFY MAINTENA is required when administered concomitantly with famotidine, valproate, lithium, lorazepam [see Clinical Pharmacology (12.3) ] . In addition, no dosage adjustment is necessary for substrates of CYP2D6 (e.g., dextromethorphan, fluoxetine, paroxetine, or venlafaxine), CYP2C9 (e.g., warfarin), CYP2C19 (e.g., omeprazole, warfarin), or CYP3A4 (e.g., dextromethorphan) when coadministered with ABILIFY MAINTENA. Additionally, no dosage adjustment is necessary for valproate, lithium, lamotrigine, lorazepam, or sertraline when coadministered with ABILIFY MAINTENA. [See Clinical Pharmacology (12.3) ] .

8 USE IN SPECIFIC POPULATIONS Pregnancy: May cause extrapyramidal and/or withdrawal symptoms in neonates with third trimester exposure ( 8.1 ) Lactation: Monitor the breastfed infant for dehydration and lack of appropriate weight gain ( 8.2 ) 8.1 Pregnancy Pregnancy Exposure Registry There is a pregnancy exposure registry that monitors pregnancy outcomes in women exposed to ABILIFY MAINTENA during pregnancy. For more information contact the National Pregnancy Registry for Atypical Antipsychotics at 1-866-961-2388 or visit http://womensmentalhealth.org/clinical-and-research-programs/pregnancyregistry/. Risk Summary Neonates exposed to antipsychotic drugs, including ABILIFY MAINTENA, during the third trimester of pregnancy are at risk for extrapyramidal and/or withdrawal symptoms following delivery (see Clinical Considerations ). Overall available data from published epidemiologic studies of pregnant women exposed to aripiprazole have not established a drug-associated risk of major birth defects, miscarriage, or adverse maternal outcomes. There are risks to the mother associated with untreated schizophrenia or bipolar I disorder and with exposure to antipsychotics, including ABILIFY MAINTENA, during pregnancy (see Clinical Considerations ) . Aripiprazole exposure during pregnancy may decrease milk supply in the post-partum period [see Use in Specific Populations (8.2) ] . In animal reproduction studies, oral and intravenous aripiprazole administration during organogenesis in rats and/or rabbits at doses 10 and 11 times, respectively, the maximum recommended human dose (MRHD) produced fetal death, decreased fetal weight, undescended testicles, delayed skeletal ossification, skeletal abnormalities, and diaphragmatic hernia. Oral and intravenous aripiprazole administration during the pre- and post-natal period in rats at doses 10 times the MRHD produced prolonged gestation, stillbirths, decreased pup weight, and decreased pup survival (see Data ) . The background risk of major birth defects and miscarriage for the indicated population are unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Clinical Considerations Disease-associated maternal and/or embryo/fetal risk There is a risk to the mother from untreated schizophrenia or bipolar I disorder, including increased risk of relapse, hospitalization, and suicide. Schizophrenia and bipolar I disorder are associated with increased adverse perinatal outcomes, including preterm birth. It is not known if this is a direct result of the illness or other comorbid factors. Fetal/Neonatal Adverse Reactions Extrapyramidal and/or withdrawal symptoms, including agitation, hypertonia, hypotonia, tremor, somnolence, respiratory distress and feeding disorder have been reported in neonates who were exposed to antipsychotic drugs (including oral aripiprazole) during the third trimester of pregnancy. These symptoms have varied in severity. Some neonates recovered within hours or days without specific treatment; others required prolonged hospitalization. Monitor neonates exhibiting extrapyramidal and/or withdrawal symptoms and manage symptoms appropriately. Data Animal Data In animal studies, aripiprazole demonstrated developmental toxicity, including possible teratogenic effects in rats and rabbits. Pregnant rats were treated with oral doses of 3, 10, and 30 mg/kg/day which are approximately 1 to 10 times the MRHD of 30 mg/day on a mg/m 2 basis of aripiprazole during the period of organogenesis. Treatment at the highest dose caused a slight prolongation of gestation and delay in fetal development, as evidenced by decreased fetal weight and undescended testes. Delayed skeletal ossification was observed at 3 and 10 times the oral MRHD on mg/m 2 basis. At 3 and 10 times the oral MRHD o …

12.1 Mechanism of Action The mechanism of action of aripiprazole in the treatment of schizophrenia and bipolar I disorder is unknown. The efficacy of aripiprazole could be mediated through a combination of partial agonist activity at dopamine D 2 and serotonin 5-HT 1A receptors and antagonist activity at 5-HT 2A receptors.
