Fluorouracil interferes with the growth of skin cells. Fluorouracil works by causing the death of cells which are growing fastest, such as abnormal skin cells.
Fluorouracil topical (for the skin) is used to treat scaly overgrowths of skin (actinic or solar keratoses). Fluorouracil topical may also be used in the treatment of superficial basal cell carcinoma.
