[A case of allergic cross reaction between tricyclic antidepressants and maprotiline].
Although a 76-year-old woman with a diagnosis of depression began a course of maprotiline, the drug was discontinued after 14 days when she developed a rash. She was started on lofepramine in substitution for maprotiline. Four years later, lofepramine treatment was stopped and to amoxapine treatment introduced due to the aggravation of depressive symptoms. On the second day of this regimen, she developed a pruritic rash. She stopped the medication immediately. Because the rash disappeared gradually, lofepramine treatment was restarted. But her recovery was restrained and new skin lesions developed. Again, she stopped the medication, and the rash cleared within several days. This case suggests the existence of cross-allergenicity between tricyclic antidepressants and maprotiline.
