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.
Slight burning, skin redness, and peeling may occur. These effects are expected. If any of these effects worsen, tell your doctor or pharmacist promptly.
If your doctor has directed you to use this medication, remember that he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.
Tell your doctor right away if any of these unlikely but serious side effects occur: spreading skin redness around the treated area, signs of infection (e.g., pus, milky/bloody discharge), formation of a deep sore (ulcer) at the treatment site.
A very serious allergic reaction to this drug is rare. However, seek immediate medical attention if you notice any symptoms of a serious allergic reaction, including: rash, itching/swelling (especially of the face/tongue/throat), severe dizziness, trouble breathing.

If you are going to have an MRI test, tell testing personnel if you are using the patch. Some patches may contain metals that can cause serious burns during an MRI. Ask your doctor whether you will need to remove your patch before the test and apply a new patch afterward, and how to do so properly.
Caution is advised when using this drug in the elderly because they are more likely to have blood circulation problems that may make it more difficult for the skin to heal.
