How It Works
Why It Is Used

- Is an inexpensive and safe home treatment.
- Causes minimal or no pain.
- May only be effective when used regularly over a period of time.
Salicylic acid should not be used:
How Well It Works
Nonprescription salicylic acid is as effective as or more effective than other treatments, with minimal risk and pain.1
- A recent review of research suggests that salicylic acid is a safe treatment that effectively eliminates warts up to 75% of the time. By comparison, placebo or no treatment produced an approximate clearance rate of 50%.2
- There is currently no evidence that cryotherapy is any more effective than salicylic acid.1
Salicylic acid can irritate or damage healthy skin surrounding the wart. As a prevention measure, cover the surrounding skin with a doughnut-shaped pad or bandage when applying salicylic acid. If you experience discomfort with salicylic acid treatment, try applying it less often.
Rarely, salicylic acid treatment causes scarring.

What To Think About
- Avoid getting salicylic acid on your unaffected skin. Salicylic acid should touch only the wart.
- Dead tissue contains living wart virus, so dispose of the dead skin carefully. The pumice stone or file will also have living wart virus on it. Don't use the file or pumice stone for any other purpose, or you may spread the virus.
- If treatment causes the area to become too tender, stop using the medication for 2 to 3 days.
- If your warts do not go away after 2 to 3 months of treatment with salicylic acid, or if they recur, consider a stronger preparation, another type of treatment, or no treatment.
