Substance Name
Salicylic Acid
Dosage Form
Patch - A drug delivery system that often contains an adhesive backing that is usually applied to an external site on the body. Its ingredients either passively diffuse from, or are actively transported from, some portion of the patch. Depending upon the patch, the ingredients are either delivered to the outer surface of the body or into the body. A patch is sometimes synonymous with the terms ‘extended release film’ and ‘system’.
Administration Route
Topical - Administration to a particular spot on the outer surface of the body. The E2B term TRANSMAMMARY is a subset of the term TOPICAL.
Active Ingredient(s)
SALICYLIC ACID 400 mg/g
Usage Information
This medication is used on the skin to treat common skin and foot (plantar) warts. Salicylic acid helps cause the wart to gradually peel off. This medication is also used to help remove corns and calluses. This product should not be used on the face or on moles, birthmarks, warts with hair growing from them, or genital/anal warts. Salicylic acid is a keratolytic. It belongs to the same class of drugs as aspirin (salicylates). It works by increasing the amount of moisture in the skin and dissolving the substance that causes the skin cells to stick together. This makes it easier to shed the skin cells. Warts are caused by a virus. Salicylic acid does not affect the virus.
