The optimal daily dose of risperidone for most patients is now recommended at 4 mg/day, a decrease from previous guidelines. Lower doses and slower titration may be beneficial for specific patient groups, including the elderly and adolescents.

Area of Science:

  • Psychopharmacology
  • Clinical Psychiatry

Background:

  • Clinical trial dosages may not reflect real-world patient populations.
  • Original risperidone trials used higher doses (6 mg/day) in specific patient groups.

Purpose of the Study:

  • To re-evaluate and recommend optimal risperidone dosing strategies based on current clinical evidence.
  • To provide updated dosing guidelines for risperidone in diverse patient populations.

Main Methods:

  • Comprehensive literature search including MEDLINE, clinical abstracts, and real-world data.
  • Analysis of naturalistic studies, clinical audits, phase 4 trials, and PET data.

Main Results:

  • The current recommended target dose for risperidone is 4 mg/day for most patients.

  • Less rapid dose titration is now advised compared to initial recommendations.

    • Conclusions:

    • Updated risperidone dosing (4 mg/day) is supported by extensive clinical data and experience.
    • Lower doses and slower titration are suggested for elderly, young, and first-episode patients.
