[Agranulocytosis under metapramine. A "well-known" effect without bibliographical data].

Metapramine (Timaxel) is a tricyclic antidepressant drug devoid of anticholinergic properties. As other psychotropic drugs, it may induce hyperthermia and several case-reports have been published. Agranulocytosis is an exceptional side-effect of this drug. Even if several cases have been reported to Pharmacovigilance structures in France, as far as we know there is no publication of this unwanted effect. The authors reported the case of an old woman who has presented two episodes of fever and asthenia. Blood formula was both times characterized by agranulocytosis without anemia nor thrombocytopenia. The accidental rechallenge of metapramine permitted to conclude to a causal relationship between these hematological events and metapramine intake.
