Abstract

We report on a patient on clozapine treatment who was admitted to our hospital with pneumonia. He had stopped smoking a few weeks before admission. The serum clozapine rose to a toxic level, most likely due to the combination of infection and smoking cessation. Physicians and pharmacists are often not aware of risk factors for decreased metabolism of clozapine.
