Warnings

Since the tips of applicators and pencils are small and standardised, there is less of a risk of excess being applied accidentally. Silver nitrate is a hazard due to its causticity, and is toxic when taken by mouth. However, absorption of silver nitrate through intact skin is negligible. Due to its chemical reactivity and the fact that it is metabolically highly refractory, there is a low risk of systemic toxicity if applied externally.The moistened point is applied directly to the wart for one to two minutes. Treatment may be repeated after 24 hours to a maximum of 3 applications Applied topical to area to be treated.
