 Aim: We conducted a chart review to investigate the detailed outcomes of patients with schizophrenia who discontinued long-acting injectable second-generation antipsychotic (LAI-SGA) therapy due to adverse events (AEs). Methods: The study included patients with schizophrenia and related psychotic disorders who commenced LAI-SGA therapy between January/1//2009 and March/31/2020 at Fujita Health University Hospital in Toyoake, Japan. Results: We conducted a chart review of 157 patients with schizophrenia. At the time of this survey, 4 (6.9%), 5 (12.2%), and 10 (17.2%) of the patients in the aripiprazole once monthly, paliperidone palmitate, and risperidone-LAI groups, respectively, discontinued due to AEs since the start of LAI-SGA therapy. Three patients required hospitalization for AE treatment. Conclusion: The severity of these AEs in most patients is moderate (ie, no hospital treatment required). Due to the small sample size, a larger study is needed to confirm/replicate our study results. © 2021 The Authors.
