Clinical Practice Guideline on the Choice of First Antipsychotic Medicine for Females Experiencing a First-Episode of Psychosis

Early intervention in first-episode psychosis (FEP) is critical for long-term outcomes with antipsychotic medicines among the primary treatment options. However, existing clinical practice guidelines (CPGs) do not provide sex-specific recommendations, despite females experiencing distinct vulnerabilities to antipsychotic side-effects. In particular, hyperprolactinemia and cardiometabolic side-effects are associated with substantial subjective distress and potential long-term physical health risks for females across the reproductive lifespan. We aimed therefore to develop a CPG on the preferred antipsychotic medicines for females experiencing FEP.
