Carac comes in cream form only.
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).
Efudex is available in cream and solution forms.
If it is necessary to cover the treated area, use a porous gauze dressing to avoid skin reactions.
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.
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.

Superficial Basal Cell Carcinomas
Twice a day, apply enough cream or solution to cover the affected area.
For this condition, use only the 5% strength of Efudex.
Continue the treatment for at least 3 to 6 weeks it may take 10 to 12 weeks of application before the lesions are gone.
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.
The usual length of treatment is from 2 to 4 weeks.
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.
You may not see complete healing of the affected area for 1 to 2 months after ending the treatment.
Your doctor will want to monitor your condition to make sure it has been cured.
Although no specific information is available on Efudex overdosage, any medication prescribed in excess can have serious consequences.
If you suspect an overdosage, seek medical attention immediately.
