What should clinicians know about Aristada Initio (aripiprazole lauroxil LAI)?

Aristada Initio (aripiprazole lauroxil) is a long-acting, one-time loading dose injectable (LAI) formulation of aripiprazole used to avoid the necessity of oral Abilify (aripiprazole). It is FDA-indicated to treat adults with schizophrenia when initiating Aristada (aripiprazole lauroxil).

Establishing Tolerability

  • Establish tolerability with oral aripiprazole prior to initiating Aristada or Aristada Initio for patients who are aripiprazole naïve.


  • A 675 mg single dose (injection volume of 2.4 ml) is given to initiate (or re-initiate) Aristada with one oral dose of Abilify (aripiprazole). One Initio injection  and one 30mg oral dose of Abilify (aripiprazole) results in serum concentrations comparable to 21-days of oral aripiprazole.
    • Initiate treatment on day 1 with:
      • Aristada Initio injection PLUS
      • A single dose of 30mg oral aripiprazole PLUS
      • The first dose of Aristada (441, 662, 882, or 1064 mg). The first dose of Aristada can be given on same day as Initio or up to 10 days later.
    • A subsequent dose of Aristada will next be given either 4, 6, or 8 weeks later, depending on prescribed dose and frequency regimen. See the clinical tip on Aristada.
    • Aristada Initio cannot be used for maintenance treatment, only for one-time initiation

Practical issues (including administration)

  • Aristada Initio is only to be administered as an IM injection by a healthcare provider.
    • It can be administered in deltoid or gluteal muscle.
    • Avoid injecting Aristada and Aristada Initio concomitantly in the same muscle.
