Therapeutic indications

Duofilm is a medication for the topical treatment of warts. The 15 ml glass bottle, with brush applicator, contains the active ingredients salicylic acid (16.7 %) and lactic acid (15 %). Applied topically, salicylic acid acts on the surface layer of the skin to promote shedding (desquamation). Lactic acid suppresses the wart skin thickening process. The elastic colloidal film provides a viscous vehicle for accurate application and the penetration of active ingredients into warts. The lactic acid also forms a film that helps keep the skin moisturised, facilitating the elimination of warts.

How to use it

Apply to the wart once a day, preferably in the evening before going to bed, according to the following instructions:

  • 1. Soak the affected area in warm water for around 5 minutes, and then dry thoroughly with a clean towel.

  • 2. Rub the wart with a nail file, pumice stone, emery board or rough cloth, taking care not to cause any bleeding.

  • 3. With the special applicator brush, apply Duofilm directly onto the wart, taking care not to spread it onto the surrounding healthy skin, in order not to irritate it.

  • 4. Allow the Duofilm to dry completely. Cover localised foot or extensive areas with a plaster to facilitate absorption of the active ingredients.

Treatment Duration

The treatment should be repeated every day until the wart has completely disappeared, and normal skin texture has been restored.

In the case of warts, a visible improvement should be observed in 1 to 2 weeks, but the maximum effect is generally seen after 4 to 8 weeks. In any case, it is recommended you consult your doctor or pharmacist if the wart persists beyond 12 weeks of treatment


Duofilm should not be applied to large areas, the face or the anogenital area.

If the product comes into contact with mucous membranes or the eyes, rinse immediately and abundantly with water, remove any colloidal film that has formed, and continue rinsing with water for at least a 15 minutes.

Duofilm is not recommended for warts that cover an area of the body more than 5cm2 (approximately the size of a postage stamp)

Duofilm should only be used when clearly needed, and under direct medical supervision. Application on children must be fully supervised by an adult.
