A 43-year-old female had been taking loflazepate ethyl (Meilax
®) and sulpiride (Dogmatyl
®) for one year and milnacipran (Toledomin
®) for 6 months for depressive psychosis. Since these drugs were not very effective, Toledomin
® was replaced by maprotiline (Ludiomil
®). Two weeks later, at the beginning of October 2004, erythema developed on her dorsal hands. The following day, the erythema spread over her body, and facial edema appeared. She was referred to our hospital. At the first examination, we noted erythema multiforme over her entire body and conjunctival congestion of both eyes with facial edema. Examination of biopsy specimen taken from erythema of the left forearm showed dermal edema and infiltrates of lymphocytes and eosinophils around the vessels in the upper dermis. First, we assigned the diagnosis of drug eruption due to Ludiomil
®. After admission, the eruption improved by systemic steroid therapy; however, upon gradual reduction of prednisolone, erythema recurred. The only positive results of the patch test and DLST were for Meilax
®. Finally we diagnosed the patient as having drug eruption due to Meilax
®, which she had been taking for one year.
