Patients should avoid exposure of the photosensitive treatment sites to sunlight or bright indoor light for at least 40 hours after application of LEVULAN KERASTICK. Exposure may result in a stinging and/or burning sensation and may cause erythema or edema of the lesions. Sunscreens will not protect against photosensitivity reactions caused by visible light.
The most common side effects include scaling/crusting, hypo/hyper-pigmentation, itching, stinging, and/or burning, erythema and edema. Severe stinging and/or burning at one or more lesions being treated was reported by at least 50% of patients at some time during the treatment.
LEVULAN KERASTICK should not be taken by patients who have cutaneous photosensitivity at wavelengths at 400-450 nm, porphyria, or known allergies to porphyrins, and in patients with known sensitivity to any of the components of the LEVULAN KERASTICK for Topical Solution. LEVULAN KERASTICK has not been tested on patients with inherited or acquired coagulation defects. [...]
