Reintroduction of clozapine after clinical recovery of induced pericarditis
Keywords:
pericarditis, pericardial effusion, clozapine, adverse reactionAbstract
Introduction: Clozapine is recommended for treatment-resistant schizophrenia. Albeit infrequently, clozapine may cause severe cardiology adverse reactions, such as myocarditis and pericarditis, in which case it must be stopped. Nevertheless, if the clinical course of the mental illness gets worse, reintroduction of clozapine may be weighed.Case presentation: We present a case report of a patient diagnosed with pericarditis associated to clozapine, who experienced a remarkable worsening of the course of illness after stopping it. One year later clozapine was successfully reintroduced under hospitalization and strict monitoring of several parameters, and patient clinically improved.
Discussion: Although pericarditis is a rare side effect of clozapine, in those cases in which there is a worsening of psychotic symptoms, its reintroduction is a major dilemma for which there are no specific guidelines.
Conclusion: It’s suggested considering the reintroduction of clozapine (adequately monitored) in clinical cases with similar physical and psychiatric symptoms. Protocols and guidelines for clozapine reintroduction after severe cardiological adverse events are needed.
