Hypersensitivity reactions resulting in rash and pruritus have been reported in up to 1% of patients treated with lomefloxacin. Photosensitivity can occur in up to 2.4% of treated patients.

Moderate to severe phototoxic reactions have occurred in patients exposed to direct or indirect sunlight or to artificial light during or following lomefloxacin treatment. These reactions have also occurred in patients exposed to shaded or diffuse light, including exposure through glass. Rarely, phototoxic reactions have occurred several weeks after discontinuation of lomefloxacin. Exposure to sunlight should be avoided during lomefloxacin therapy, even when a sunscreen is used. Exposure should also be avoided for several days after lomefloxacin is discontinued. Patients should be advised to discontinue lomefloxacin use at the first sign of a phototoxic reaction.
