Patient leaflet - Occlusal 26% w/w cutaneous solution
1. What Occlusal is and what it is used for
Occlusal is used to treat and remove raised warts (usually found on the hands, elbows or knees) and verrucas (warts on the feet). Occlusal is a special solution which can be easily applied to the wart, dries quickly, needs no plasters and if used properly should cause minimal irritation.
Warts, or verrucas as they are often called, are found most commonly on the hands, feet and knees. They are commonest amongst children of school age.
Warts are caused by a virus which gets into the upper layers of the skin. The body then reacts to the virus, which leads to the formation of the wart or verruca. Warts are most frequently transmitted by contact, e.g. swimming pools and communal changing rooms are often associated with infection. Warts can occur singly or in groups and can be transferred from one part of the body to another, e.g. from one foot to the other.
Occlusal contains a high concentration of salicylic acid which when used regularly removes the dead cells from the outer layer of the skin and steadily reduces the size of the wart.
