What are Warts?

Warts are small, rough, and hard growths that appear on the skin. They are caused by the human papillomavirus (HPV) and are highly contagious. Warts can appear on any part of the body, but they are most commonly found on the hands, feet, and face.

What is 5-fu Salicylic Acid?

5-fu Salicylic Acid is a topical medication used to treat warts. It is a combination of 5-fluorouracil (5-fu) and salicylic acid. 5-fu is an anti-cancer drug that works by stopping the growth of abnormal cells. Salicylic acid is a keratolytic agent that softens and loosens the outer layer of the skin.

How Does 5-fu Salicylic Acid Work?

When applied to warts, 5-fu salicylic acid works by destroying the abnormal cells that make up the wart. The salicylic acid softens the outer layer of the skin, allowing the 5-fu to penetrate deeper into the wart. Over time, the wart will gradually shrink and disappear.

How to Use 5-fu Salicylic Acid?

Before using 5-fu salicylic acid, wash the affected area with soap and water. Dry the area thoroughly. Apply a small amount of the medication to the wart, making sure to cover the entire area. Cover the wart with a bandage or tape. Leave the medication on for at least 8 hours, then remove the bandage and wash the area with soap and water. Repeat this process daily for up to 12 weeks, or until the wart disappears.

Who Should Not Use 5-fu Salicylic Acid?

5-fu Salicylic Acid should not be used by pregnant or breastfeeding women. It should also not be used on warts that are bleeding, infected, or located on the face or genital area.

Side Effects of 5-fu Salicylic Acid

Common side effects of 5-fu salicylic acid include redness, swelling, and skin irritation at the site of application. These side effects are usually mild and go away on their own. In rare cases, more serious side effects such as allergic reactions and skin discoloration may occur.

Preventing Warts

To prevent warts, it is important to practice good hygiene. Wash your hands regularly, especially after touching warts or objects that have come into contact with warts. Wear flip flops or sandals in public showers and pools. Avoid sharing towels, razors, or other personal items with others.
