Efudex

Pronounced: EFF-you-decks
Generic name: Fluorouracil
Other brand name: Carac

Why is Efudex prescribed?

Efudex and Carac are prescribed for the treatment of actinic or solar keratoses (small red horny growths or flesh-colored wartlike growths caused by overexposure to ultraviolet radiation or the sun). Such growths may develop into skin cancer. When conventional methods are impractical--as when the affected sites are hard to get at--the 5 percent strength of Efudex is useful in the treatment of superficial basal cell carcinomas, or slow-growing malignant tumors of the face usually found at the edge of the nostrils, eyelids, or lips. Efudex is available in cream and solution forms. Carac comes in cream form only.

Most important fact about Efudex

If you use an airtight dressing to cover the skin being treated, there may be inflammatory reactions in the normal skin around the treated area. If it is necessary to cover the treated area, use a porous gauze dressing to avoid skin reactions.
