What should you know about Duofilm for warts?

Duofilm is a liquid applied to the wart surface. Its keratolytic ingredients loosen thickened skin so treated tissue can shed over time. Warts are caused by a virus and may recur or spread to nearby skin, especially when picked. A rough bump is not automatically a wart: corns, calluses, moles, and other lesions can look similar. Diagnosis is especially useful when the spot bleeds, changes colour, hurts, or sits on the face or genitals.

Follow the product label or your clinician’s instructions. Keep the surrounding skin protected, apply only to the wart, let the liquid dry, and wash your hands afterward. Do not use it on broken, infected, or inflamed skin unless a clinician advises it. Stop and seek advice if burning, swelling, blistering, or persistent soreness develops. Do not share towels, nail tools, or footwear, and avoid picking the lesion. A clinician can discuss [Wart Removal](/treatments/surgical-dermatology/wart-removal/) or alternatives such as [Cryotherapy (Lesion Removal)](/treatments/surgical-dermatology/cryotherapy-lesion-removal/).

Have the lesion examined before treating it if it is on the face, near the eye, on genital skin, or if you have diabetes, poor circulation, reduced sensation, or a weakened immune system. Seek care for spreading redness, pus, increasing warmth, severe pain, or bleeding that does not settle. Arrange review when several treatment attempts fail or the diagnosis is uncertain; options may include [Electrosurgery](/treatments/surgical-dermatology/electrosurgery/) or [Imiquimod Treatment](/treatments/medical-dermatology/imiquimod-therapy/) when appropriate.

Is this definitely a wart? Is Duofilm suitable for its location and my health conditions? How should I protect nearby skin? When should I stop treatment and return? Which alternative would you consider if it persists?
