title: Hospital admission for xanthine toxicity.
abstract: A follow-up study of 35,909 outpatients who filled more than 220,000 prescriptions for theophylline over 9 years revealed 30 hospitalizations for xanthine toxicity. The overall estimated incidence rate of 7.8/10,000 person-years at risk indicates that in this population, hospitalization for xanthine toxicity is a relatively rare event.
