In the Clinical Challenge, “Treatment of First-Episode Schizophrenia in a Young Woman,”1 published online October 30, 2019, there was an error in a quiz answer choice. Answer A was corrected to “Consider the risk of adverse events and which drugs are approved for use” instead of “Commence treatment with oral amisulpride.” In addition, the Discussion and Patient Outcome sections have been corrected to note that the drug amisulpride is not approved for use in the United States but is approved for use in the United Kingdom where the patient was treated. This article has been corrected online.
