Risperidone Dosage Adjustment for Persistent Auditory Hallucinations

Monitoring and Dose Adjustment

  • If extrapyramidal symptoms (EPS) occur, consider dose reduction rather than adding anticholinergic medication, as recommended by the American Academy of Family Physicians 1

Special Considerations

  • For persistent auditory hallucinations, the therapeutic target is often higher than for other symptoms, with studies showing that risperidone can significantly reduce hallucinations, reducing distressing dreams/hallucinations from 38% to 19% after 6 weeks of treatment with doses ranging from 1-3 mg (mean 2.3 mg), according to the American Academy of Sleep Medicine 2, 3
  • Failure to recognize that non-verbal auditory hallucinations may require higher doses than the current 3 mg can lead to inadequate treatment, as noted by the American Academy of Sleep Medicine 2, 3
