Warts are growths on
the skin caused by viruses (germs that can only be seen with a special microscope). They vary in size and appearance. Warts are most often found on the hands and feet but can be anywhere on the skin. They are spread from one person to the next by touching. Warts are more common in children and young adults but may appear at any age. Sometimes they go away in weeks or months with no treatment but others last for years. Your child's wart can be treated with
liquid nitrogen. Liquid nitrogen freezes and destroys both the wart and a small area of normal skin around the wart.What to Expect
What to Do
- Keep the area clean and dry. Do not break the blister. Wash it every day with soap and water. Dry well and cover it with a Band-Aid®.
- When the blister breaks, wash the area daily with soap and water. Apply double antibiotic ointment such as Polysporin® and cover the area with a Band-Aid®.
- Give acetaminophen (Tylenol®) or ibuprofen (Advil® or Motrin®) as needed for pain. Read the label to know the right dose for your child. Do not give aspirin
When to Call the Doctor
The risk of infection after treatment is small. Call the doctor if:
- Your child has a fever over 101 degrees F .
- The blister opens after treatment and does not heal.
- The blister is red, swollen, feels hot or drains pus.
Remember, one treatment with liquid nitrogen may not remove the wart completely. The skin doctor (dermatologist) will decide if it needs to be treated again.
