<unk>  can be induced by a wide range of medications, excessive UV-A exposure, and hemodialysis. One frequently reported drug is naproxen. A frequent source of UV-A exposure is tanning booths. As recognition of<unk>  increases and the number of new medications expands, the list of etiologic agents associated with<unk>  will most likely continue to grow. Agents associated with<unk>  are as follows: * Propionic acid derivatives (NSAIDs) - naproxen, diflunisal, ketoprofen, oxaprozin, mefenamic acid, rofecoxib * Ketone NSAID-nabumetone * Antibiotics - nalidixic acid, tetracycline, oxytetracycline, ampicillin-sulbactam, cefepime, fluoroquinolones (M Poh, personal communication, June 1999) * Antifungals - voriconazole * Diuretics - furosemide, chlorthalidone, butamide, triamterene/hydrochlorothiazide * Antiarrhythmics - amiodarone * Chemotherapy - 5-fluorouracil * Immunosuppressants - cyclosporine * Sulfones - dapsone * Vitamins - brewers' yeast, pyridoxine * Vitamin A derivatives - etretinate, isotretinoin * Muscle relaxants - carisoprodol/aspirin * Nonsteroidal antiandrogens - flutamide * Other - hemodialysis, excessive UV-A, cola, oral contraceptive pills (levonorgestrel and ethinylestradiol), narrowband UV-B phototherapy (rarely)
