Clozapine rechallenge following clozapine-induced pericarditis.

To the Editor: There are many reports describing the development of myocarditis and cardiomyopathy following treatment with clozapine. Fewer reports exist about the development of pericarditis, and reports of successful rechallenges with clozapine following the development of pericarditis are particularly rare. We report the case of a patient successfully resumed on clozapine treatment following the development of pericarditis and propose an approach to following up such patients.
