Oculogyric crisis in patients taking cetirizine.
PURPOSE: To report oculogyric crisis in patients receiving cetirizine and inform clinicians on the characteristics of this drug-induced ocular side effect. METHODS: For this retrospective, observational case series, case reports were collected from the National Registry of Drug-Induced Ocular Side Effects (Casey Eye Institute, Portland, Oregon). The World Health Organization Causality Assessment Guide of Suspected Adverse Reactions was used to categorize the cases. RESULTS: Nine cases were reported, with eight occurring in the pediatric age group. Dosage ranged from 5 to 10 mg orally and onset of symptoms ranged from 3 to 184 days. Six cases of oculogyric crisis had positive rechallenge data. Eight cases had complete neurologic consultation including radiographic studies. CONCLUSIONS: Cetirizine can cause oculogyric crisis, especially in the pediatric age group. Extensive neurologic workups may be avoided if clinicians recognize this drug-induced ocular side effect.[1]References
