How do I use this medicine?

Your child’s healthcare provider or nurse will explain how and when to give this medicine to your child.  If you have questions, ask your child’s healthcare provider, nurse, medical assistant, or pharmacist.

1. Soak the area with the wart in warm water for 20 to 30 minutes.  Your child may take a bath instead of soaking.  Keep the area being treated in the water when taking a bath.  After the bath, dry the area well and then put the salicylic acid on.
2. Make sure that the medicine only touches the wart and does not get onto the surrounding skin.
3. Cover the salicylic acid with adhesive tape.
4. If using a patch, it can be left on for up to 48 hours.
5. After 48 hours, repeat soaking the affected area.  Then use an emery board, pumice, or foot file to remove any dead skin before you apply the medicine.  This is important to allow the medicine to penetrate deep enough in the skin to reach the wart.   
Do not let anyone else take this medicine.
It may be easiest to put this medicine on before bed and remove in the morning.
