Prescription Drug Index

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.

When Efudex is applied to affected skin the skin becomes abnormally red blisters form and the surface skin wears away. A lesion or sore forms at the affected site and the diseased or cancerous skin cells die before a new layer of skin forms.

ADULTS

Actinic or Solar Keratosis

Apply Efudex cream or solution 2 times a day or Carac cream once a day in an amount sufficient to cover the affected area. Continue using the medication until the inflammatory response reaches the stage where the skin wears away a sore or lesion forms and the skin cells die; your doctor will then have you stop using the medication. The usual length of treatment is from 2 to 4 weeks. You may not see complete healing of the affected area for 1 to 2 months after ending the treatment.

Superficial Basal Cell Carcinomas

For this condition use only the 5% strength of Efudex. Twice a day apply enough cream or solution to cover the affected area. Continue the treatment for at least 3 to 6 weeks; it may take 10 to 12 weeks of application before the lesions are gone.

Your doctor will want to monitor your condition to make sure it has been cured.
