[Pulmonary eosinophilic infiltration with pneumothorax during trimipramine treatment].

Three weeks after starting treatment with the antidepressant trimipramine a 55-year-old man developed increasing cough, fatigue and lack of appetite. The blood count revealed marked eosinophilia (15%) and the chest X-ray showed bilateral pulmonary infiltrates. Later a left spontaneous pneumothorax occurred. When trimipramine was discontinued (as the suspected cause of the described changes) the symptoms quickly subsided and the infiltrate as well as the eosinophilia quickly disappeared.
