Bottom Line
Clozapine often is used as a last resort for patients with treatment-resistant schizophrenia, but its side-effect profile requires careful management and monitoring. If a patient taking clozapine shows tachycardia, consider cardiomyopathy. Evaluation might include lab testing, electrocardiography, and echocardiography. Symptoms often resolve when clozapine is discontinued.
