Aristada Initio (aripiprazole lauroxil 650 mg) is used as a long-acting, single intramuscular (IM) injection, with a single oral dose of aripiprazole, for adult patients starting or re-initiating treatment with Aristada to treat schizophrenia. Aristada Initio is not for repeat dosing. Aristada is the long-acting maintenance treatment form of aripiprazole lauroxil given by IM injection. Aristada is administered monthly, every 6 weeks, or every 8 weeks, depending on dose (441 mg, 662 mg, 882 mg or 1064 mg). The first Aristada injection may be administered on the same day as Aristada Initio or up to 10 days later. Aristada Initio is not interchangeable with Aristada due to differences in how these drugs act in the body.
