Glutaraldehyde (Glutarol)

Glutarol is a liquid medication containing the active ingredient glutaraldehyde. This substance is used primarily as a wart paint and a verruca treatment. Glutaraldehyde kills bacteria and viruses on the skin so that warts and other issues have a chance to heal.

What is glutaraldehyde?

Glutaraldehyde is a wart and verruca medication often sold under the brand names Glutarol and Cidex. Glutaraldehyde is a disinfectant as well as a medication and a preservative. As a disinfectant, it can sterilize surgical equipment. As a medication, it treats the warts that appear on the bottom of the feet.

Glutaraldehyde (Glutarol) solution works by killing the bacteria, viruses and other dangerous substances that cause warts and verrucas to appear on the skin.

When applied to the skin, this substance will harden the upper layer of epidermis, often making it tough and whitening the flesh. This might seem strange at first, but the glutaraldehyde (Glutarol) solution medication is actually helping to kill the wart, so that it can simply wear away like any dead skin over time. The hardening of the skin that is caused when you apply glutaraldehyde (Glutarol) also means that it is less likely that the virus causing the infection will spread on the skin or infect other people.

The new skin will continue to grow underneath the verruca or wart. This new skin should be free from any presence of the previous virus.

Although glutaraldehyde (Glutarol) can work quite quickly, it sometimes takes a while for the wart or verruca to disappear altogether. If several weeks pass and you do not see any difference, then you may need to speak to your doctor about using a different form of treatment.

Once you have read through the leaflet, wash your hands and the area of skin to be treated before applying the medication.

Soak your foot and the wart in hot soapy water for a period of two or three minutes to help loosen the hard skin around the wart or verruca. You can rub any of the loose skin around the area away with a pumice stone if necessary. Once your skin is dry, use the applicator provided with this liquid to apply two light layers of the medication. Give the first layer time to dry before you start applying the second. Try to avoid letting the liquid spread to other parts of skin as much as possible.
