Repeated occurrence of clozapine-induced myocarditis in a patient with schizoaffective disorder and comorbid Parkinson's disease.

: Myocarditis is a rare but life threatening adverse effect of clozapine. Some symptoms of myocarditis--elevated temperature, tachycardia and fatigue--appear commonly during the onset of treatment with clozapine and during the dose titration. We present a case of a patient with concurrent schizoaffective disorder and Parkinson's disease, who twice developed clozapine-induced myocarditis. All symptoms disappeared after the discontinuation of the drug. Early diagnosis, discontinuation of clozapine and supportive therapy of myocarditis lower the risk of a fatal outcome.
