Full Prescribing Info
Dosage/Direction for Use
Posology: For patients who have never taken aripiprazole, tolerability with oral aripiprazole must occur prior to initiating treatment with Abilify Maintena.
The recommended starting and maintenance dose of Abilify Maintena is 400 mg.
Titration of the dose of this medicinal product is not required. It should be administered once monthly as a single injection (no sooner than 26 days after the previous injection).
After the first injection, treatment with 10 mg to 20 mg oral aripiprazole should be continued for 14 consecutive days to maintain therapeutic aripiprazole concentrations during initiation of therapy.
If there are adverse reactions with the 400 mg dosage, reduction of the dose to 300 mg once monthly should be considered.
Missed doses: (See Table 3.)

Special populations: Elderly patients: The safety and efficacy of Abilify Maintena in the treatment of schizophrenia in patients 65 years of age or older has not been established (see Precautions).
Renal impairment: No dosage adjustment is required for patients with renal impairment (see Pharmacology: Pharmacokinetics under Actions).
Hepatic impairment: No dosage adjustment is required for patients with mild or moderate hepatic impairment. In patients with severe hepatic impairment, the data available are insufficient to establish recommendations. In these patients requiring cautious dosing, oral formulation should be preferred (see Pharmacology: Pharmacokinetics under Actions).
Known CYP2D6 poor metabolisers: In patients who are known to be CYP2D6 poor metabolisers, the starting and maintenance dose should be 300 mg. When used concomitantly with strong CYP3A4 inhibitors the dose should be reduced to 200 mg (see Interactions).
Dose adjustments due to interactions: Dosage adjustments should be done in patients taking concomitant strong CYP3A4 inhibitors or strong CYP2D6 inhibitors for more than 14 days. If the CYP3A4 inhibitor or CYP2D6 inhibitor is withdrawn, the dosage may need to be increased to the previous dose (see Interactions). In case of adverse reactions despite dose adjustments of Abilify Maintena, the necessity of concomitant use of CYP2D6 or CYP3A4 inhibitor should be reassessed.
Concomitant use of CYP3A4 inducers with Abilify Maintena should be avoided for more than 14 days because the blood levels of aripiprazole are decreased and may be below the effective levels (see Interactions). (See Table 4.)

Paediatric population: The safety and efficacy of Abilify Maintena in children and adolescents aged 0-17 years have not been established. No data are available.
Method of administration: Abilify Maintena is only intended for intramuscular use and should not be administered intravenously or subcutaneously. It should only be administered by a healthcare professional. The suspension should be injected immediately after reconstitution but can be stored below 25°C for up to 4 hours in the vial. The suspension should be injected slowly as a single injection (doses must not be divided) into the gluteal or deltoid muscle. Care should be taken to avoid inadvertent injection into a blood vessel. Sites of injections should be rotated between the two gluteal or deltoid muscles.
The recommended needle for gluteal administration is a 38 mm (1.5 inch), 22 gauge hypodermic safety needle. For obese patients (Body mass index > 28 kg/m2), a 51 mm (2 inch), 21 gauge hypodermic safety needle should be used.
The recommended needle for deltoid administration is a 25 mm (1 inch), 23 gauge hypodermic safety needle. For obese patients, a 38 mm (1.5 inch), 22 gauge hypodermic safety needle should be used (see Special precautions for disposal and other handling under Cautions for Usage).
The powder and solvent vials are for single-use only.
For instructions on reconstitution of the medicinal product before administration, see Special precautions for disposal and other handling under Cautions for Usage.
