    • What is this medication and its most common uses?

      Efudex is a topical medicine (applied directly on the skin) used to treat multiple actinic or solar keratoses (small, rough, raised area of skin that has often been exposed to the sun for a long period). It is also used to treat a type of skin cancer called superficial basal cell carcinoma when usual treatment cannot be used. Efudex is available as a cream and a solution.

      Efudex works by interfering with the growth of abnormal cells found in actinic keratoses and basal cell carcinoma.

      What are the beneficial effects of this medication and when should I begin to have results?

      What: By treating your lesions, Efudex may help prevent the development or worsening of skin cancer.

      When:

      Actinic or Solar Keratoses: Complete healing of your lesions may be seen 1-2 months after completing treatment with Efudex.
