Gallerani M, Imberti D, Mari E, Marra A, Manfredini R. Risperidone and pulmonary embolism: a harmful association? Case series and review of the literature.
Objective: Risperidone is an atypical antipsychotic drug used to treat a number of psychiatric diseases, such as schizophrenia, schizoaffective and bipolar disorders and irritability in children with autism. Moreover, it is also often administered for short-term treatment of persistent aggression in people with moderate-to-severe Alzheimer's dementia. A possible association between risperidone and venous thromboembolism (VTE) has been described. We intended to verify the dimension of the problem in our hospital setting.
Methods: We considered all consecutive patients hospitalised in our Internal Medicine Department from January 2004 to December 2010, who were treated with risperidone and presented pulmonary embolism (PE).
Results: Four cases of patients, apparently free from the well-known major risk factors for VTE (i.e. cancer, prolonged immobilisation, acute cardiac and respiratory failure, infections), who presented PE associated with risperidone therapy, were reported in details.
Conclusions: A review of the available literature, discussing the possible different pathogenic reasons for this increased risk of VTE, is provided.
