LSD-Like Panic From Risperidone in Post-LSD Visual Disorder
Journal of Clinical Psychopharmacology June 1, 1996 Henry David Abraham, Anitra Mamen 50 citations
Risperidone, a medication that blocks serotonin-2 and dopamine D2 receptors, worsened symptoms in three patients with hallucinogen-persisting perception disorder (HPPD), a condition sometimes triggered by LSD that causes ongoing visual disturbances and panic. The exacerbation of LSD-like panic and visual symptoms suggests that HPPD may be a relative contraindication for risperidone use.
