Photolocalized purpura during levofloxacin therapy
Abstract
Side-effects associated with levofloxacin treatment include phototoxicity, hypersensitivity and skin disorders. Purpuric eruptions have rarely been reported. We describe the case of a 75-year-old woman who was prescribed a 15-day course of levofloxacin (500 mg twice a day) for hemorrhagic cystitis. On exposure to sunlight, the patient developed a pruritic purpuric eruption on the lower extremities. The acute reaction differed from a classical sunburn, manifesting as confluent petechiae limited to sun-exposed areas and accompanied by pruritus. This was a rare case of solar capillaritis. Purpuric eruptions on photoexposed skin should be considered another unusual side effect of levofloxacin.
How strong is the evidence?
Evidence Hub reads this as a case report, done in people. Its evidence level is 5 of 5 (Very low · case / narrative / animal / in vitro / in silico). Case reports, narrative reviews, and animal, cell or computer-model studies give the weakest evidence for human health.
