Efudex Cream (Flurouracil) belongs to a group of medications called antineoplastics. It is used topically to treat a type of skin cancer known as superficial basal cell carcinoma. It is also used to treat actinic keratosis, a skin condition that may lead to skin cancer. It works by killing the abnormal cells that are causing cancer or skin condition. Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful to people to use this medication if their doctor has not prescribed it.
Wash the area to be treated with soap and water, then dry the area thoroughly. Apply the cream to the affected area twice a day with a nonmetal applicator (e.g., a cotton swab) or while wearing a suitable glove. Apply a thin layer, enough to cover the entire affected area of the skin. If fingertips are used to apply, wash your hands well with soap and water immediately afterward. Avoid contact with the eyes, eyelids, corners of the nose, mouth, easily irritated areas, or other areas where treatment is not intended. If you apply the medication near the eyes, nose, or mouth, take care to avoid getting the medication in these sensitive areas.
This medication will cause the skin to become severely inflamed and irritated, but continue to use it for the length of time recommended by your doctor, usually for 2 to 4 weeks. Complete healing of the treated area may take 1 to 2 months after stopping treatment. If the area becomes severely irritated, contact your doctor.
It is important to use this medication exactly as prescribed by your doctor. If you miss a dose, apply it as soon as possible and continue with your regular schedule. If more than a few hours have passed, skip the missed dose and continue with your regular dosing schedule. Do not apply a double dose to make up for a missed one. If you are not sure what to do after missing a dose, contact your doctor for advice.
