How does this medication work? What will it do for me?
Fluorouracil - salicylic acid is a combination of two medications. Together they are used to reduce the growth of skin lesions called actinic keratosis on the face, forehead, and balding scalp. These lesions are caused by sun damage to the skin. If not treated, they may become cancerous.
Fluorouracil belongs to the class of medications antineoplastics. It works by interfering with cell division and growth to slow down the growth of cells. It is most active in cells that are growing quickly, such as skin cells affected by actinic keratosis. Salicylic acid is a keratolytic: it breaks down the outer layer of the skin to allow fluorouracil to be absorbed more effectively.
This medication may be available under multiple brand names and/or in several different forms. Any specific brand name of this medication may not be available in all of the forms or approved for all of the conditions discussed here. As well, some forms of this medication may not be used for all of the conditions discussed here.
Your doctor may have suggested this medication for conditions other than those listed in these drug information articles. If you have not discussed this with your doctor or are not sure why you are taking this medication, speak to your doctor. Do not stop taking this medication without consulting your doctor.
Do not give this medication to anyone else, even if they have the same symptoms as you do. It can be harmful for people to take this medication if their doctor has not prescribed it.
How should I use this medication?
The usual adult dose of fluorouracil - salicylic acid is 1 application of the solution to the lesions, once daily. Several lesions may be treated at a time, but the area being treated should not be larger than 25 cm² (5 cm × 5 cm). A total of 10 lesions may be treated at a time.
Fluorouracil - salicylic acid should only come into contact with the lesion and a very small area of healthy skin surrounding the lesion.
Clean the affected area with warm water and wait until the skin has completely dried before applying the solution.
This medication comes in a bottle with a brush applicator attached to the cap. Wipe the brush on the neck of the bottle before applying it to the affected area. After applying the solution to the lesion, let the solution dry on the skin, uncovered. A white film will form over the affected area. This improves the absorption of the medication into the lesion and protects the lesion from dirt and debris. Do not cover the treatment area with any type of dressing. Before applying the next dose, peel the film off the lesion to expose it to the next dose of medication. Warm water may also help remove the film.
Do not allow this medication to come in contact with the eyes, the inside of the nose or mouth, or the genitals. Close the lid of the bottle tightly after using to prevent it from drying out. Do not use this medication if it dries out or forms any crystals.
This medication usually starts to work within 6 weeks. Continue to use the medication for up to 12 weeks or until the lesions have completely cleared up. It may take up to 8 weeks after stopping the medication for the lesions to completely heal.
