Why is this medication prescribed?

Fluorouracil topical is prescribed for the treatment of certain types of skin conditions, including actinic keratosis (precancerous skin growths caused by sun damage) and superficial basal cell carcinoma (a type of skin cancer). It works by interfering with the growth of abnormal skin cells, thus helping to eliminate them.

• Wash hands: After applying the medication, wash your hands thoroughly to avoid accidentally transferring it to other parts of your body or objects.
