Long-acting injectable (LAI) antipsychotic medications are significantly underused. In light of their documented efficacy for treatment of psychotic symptoms and robust effect on relapse prevention, their relative lack of use is unfortunate. There are several reasons for this therapeutic neglect, including clinical settings where injections are not part of the usual routine; a belief that LAI medications are reserved for acute intervention or for aggressive or nonadherent patients; and the perception of stigmatization associated with their use. Moreover, randomized clinical trials (RCTs) comparing oral antipsychotic medications with LAI medications have often failed to document the expected advantage of assuring adherence with LAI medications because study participant selection often excludes those who are unable to adhere to the study protocol. Finally, physicians routinely overestimate patients’ adherence to oral medication regimens. In this context, 2 articles1,2 in JAMA Psychiatry regarding the use of LAI medications may stimulate reconceptualization of this aspect of pharmacotherapy for treating schizophrenia.
