About Silver nitrate and how it works

This medicine is used to treat warts and verrucas. The main ingredient silver nitrate is corrosive and destroys skin cells and is useful for treating these types of skin growths.

This medicine is available in the form of a stick which is moistened and applied directly to the wart or the verruca. You must protect the surrounding areas of healthy skin.

You should first moisten the tip of the stick with clean water. Ideally, you should use distilled water because chlorine or fluorine in household tap water can make this medicine ineffective. After moistening the tip you should hold the stick in contact with the wart or verruca for one or two minutes. You should apply the medicine once a day only. You should use no more than a total of three applications on a wart, or six applications on a verruca.

You must keep this medicine away from your eyes and other areas of sensitive skin. This medicine is not suitable for use on genital warts.

Speak to your doctor if your symptoms do not improve or if they get worse during treatment with this medicine.
