Actikerall is a skin solution containing fluorouracil and salicylic acid used to treat actinic keratosis (a pre-cancerous skin condition) in adults.
Apply Actikerall once a day, unless your doctor has instructed otherwise.
Clean and dry the affected area. Gently peel off any film from the previous day's application. Apply a thin layer of Actikerall directly onto the skin lesion with the brush once daily, let it dry to form a film, and do not cover it with a dressing.
Do not apply Actikerall to a total skin area larger than 25 cm² (5 cm x 5 cm) at one time.
