Mortality associated with clozapine: what is the evidence?

Br J Psychiatry. 2024 Sep;225(3):357-359. doi: 10.1192/bjp.2024.88.

Abstract

While clozapine has risks, relative risk of fatality is overestimated. The UK pharmacovigilance programme is efficient, but comparisons with other drugs can mislead because of reporting variations. Clozapine actually lowers mortality, partly by reducing schizophrenia-related suicides, but preventable deaths still occur. Clozapine should be used earlier and more widely, but there should be better monitoring and better management of toxicity.

Keywords: Clozapine; adverse drug reactions; education and training; mortality; safety.
