Objective：To determine the types of drugs which caused photosensitization drug eruption and the clinical features of the patients. Methods： The data of patients with photosensitization drug eruption was analyzed retrospectively. Results： Out of 68 patients, 37 patients were caused by thiazine diuretics, 19 by quinolones, 3 by doxycycline, 2 by viaminate, 2 by Simvastatin, 2 by colchicine, 1 by chlorpromazine, 1 by diltiazem and 1 by amiodarone. The lesions were located on exposed area only and mainly manifested as edem-atous erythema in 62 patients. The lesions were located on both exposed and unexposed areas and manifested as various lesions in 6 patients. All patients stopped the suspicious drugs, kept away from the sun exposure and were given oral antihistamines, nicotinamide, low-medium doses of glucocorticoid and topical calamine lotion and corticosteroids cream. Six five patients were cured after the treatment of 4 weeks. Conclusion：Thia-zine diuretics and quinolones are the most common drugs inducing the photosensitization drug eruption in our patients.
