Agranulocytosis after long-term clozapine use: a case report.
Neutropenia and the more severe, potentially life-threatening agranulocytosis are recognized side effects of clozapine that require regular, mandatory, and life-long blood monitoring. However, most cases of haematological adverse effects occur in the first few months of treatment; therefore, there are now increasing calls for the termination of the mandatory monitoring after this initial period. In this report, we present a patient with treatment-resistant schizophrenia who was successfully treated with clozapine yet developed neutropenia after 9 years. This soon evolved into agranulocytosis requiring the use of granulocyte colony-stimulating factor and eventual clozapine cessation. Such late-onset cases of agranulocytosis are isolated and rare but should not impede the drive to relax mandatory clozapine haematological monitoring, but patients and carers must be aware of potential symptoms of agranulocytosis.
期刊介绍:
International Clinical Psychopharmacology provides an essential link between research and clinical practice throughout psychopharmacology. It reports on studies in human subjects, both healthy volunteers and patients, which relate the effects of drugs on psychological processes.
A major objective of the journal is to publish fully refereed papers which throw light on the ways in which the study of psychotropic drugs can increase our understanding of psychopharmacology. To this end the journal publishes results of early Phase I and II studies, as well as those of controlled clinical trials of psychotropic drugs in Phase II and IV. Other topics covered include the epidemiology of psychotropic drug prescribing and drug taking, the sociology of psychotropic drugs including compliance, and research into the safety and adverse effects of these compounds.
