To the editor: Mexiletine, a primary amine that resembles lidocaine in chemical structure, is a new anti-arrhythmic agent without known haematologic side effects. Adverse reactions to the drug include only one case of thrombocytopenia (1). We report the case of a patient who developed thrombocytopenia after mexiletine administration.
On 18 June 1983, a 53-year-old man was hospitalized with heart failure and ischemic heart disease. Two platelet counts obtained 2 weeks and a few days before admission were normal (greater than 200 000/mm3). There was no history of drug allergy or thrombocytopenia, and no evidence of splenomegaly. Body temperature, erythrocyte sedimentation
