Clinical Context

A typical adult patient with schizophrenia or schizoaffective disorder presents for scheduled long-acting injectable antipsychotic therapy. The patient arrives at an outpatient behavioral health clinic or specialty psychiatry clinic that administers intramuscular injections. After verification of identity, current medications, allergies, and a brief assessment of mental state and injection site, a registered nurse or trained medical assistant prepares the dose of aripiprazole lauroxil in accordance with manufacturer guidance. The clinician documents indication, consent, medication lot number, and injection site (typically gluteal or deltoid). The patient is observed in the clinic for a short period for adverse reactions and discharge instructions are provided for expected side effects and next scheduled dose.

Common sites of service include outpatient behavioral health clinics, psychiatric specialty clinics, community mental health centers, and hospital outpatient departments. The typical workflow includes medication reconciliation, injection preparation and administration, post-injection observation, and documentation in the electronic medical record.
