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.
Actikerall 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 Actikerall 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 Actikerall if it dries out or forms any crystals.
Actikerall 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.
Many things can affect the dose of medication that a person needs, such as body weight, other medical conditions, and other medications. If your doctor has recommended a dose different from the ones listed here, do not change the way that you are taking the medication without consulting your doctor.
It is important to use Actikerall exactly as prescribed by your doctor.
If you miss a dose, skip the missed dose and continue with your regular dosing schedule. Do not take 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 or pharmacist for advice.
Store Actikerall at room temperature, protect it from light and moisture, and keep it out of the reach of children. Actikerall is flammable. Keep it away from fire or flames. If there is any medication left in the bottle 3 months after opening it, safely discard the remaining medication.
