At-home wart removal: what to know

Non-prescription salicylic acid products gradually remove thickened wart tissue. Treatment often requires repeated application according to the package directions, and the surrounding healthy skin should be protected. Do not cut, burn, or pick at a suspected wart yourself because this can cause injury, infection, or spread.

Warts are skin growths caused by human papillomavirus entering the outer skin. Common warts may feel rough and can interrupt normal skin lines, while plantar warts form on pressure-bearing areas of the foot and may be covered by callus. Other growths can resemble warts, so uncertainty about the diagnosis is a reason to avoid self-treatment.

Products intended for ordinary hand or foot warts are not appropriate for the face, genitals, broken skin, moles, or birthmarks. People with diabetes, reduced circulation, numbness, or a weakened immune system need professional advice before treating a foot or skin lesion at home.

Choose a product labelled for the wart's body location and follow its instructions exactly. Wash your hands after touching the area, keep personal nail tools and towels separate, and cover the wart when friction or shared surfaces could spread viral skin cells. Stop if treatment causes marked pain, an open wound, or significant irritation.

Avoid shaving across the growth because small skin injuries can transfer the virus nearby. If home care is unsuitable or has not helped after the full labelled course, a clinician can confirm the diagnosis and discuss professional wart removal options.

Seek prompt assessment if the growth bleeds without being picked, changes rapidly, develops irregular colour, becomes very painful, drains pus, or has spreading redness. A clinician should also examine a lesion when you are unsure it is a wart, when several growths appear quickly, or when it is on the face or genital area.

Ask whether the appearance and location fit a wart, whether your medical conditions or medicines affect treatment choice, and which method is least likely to injure the surrounding skin. You can also ask what change should prompt an earlier review and how to reduce spread at home.
