Silver Nitrate: Uses, Side Effects, and Medication Alertness

Silver Nitrate is a versatile inorganic compound extensively used as an antiseptic and a cauterizing agent in medicine. It is commonly available as topical solutions and application sticks for conditions such as skin infections, minor cuts, and tissue removal (ablation).


How Silver Nitrate Works

The powerful germicidal action of Silver Nitrate works by destroying bacterial cell walls. When it comes into contact with moisture on the skin or wound, it releases silver ions that penetrate microbial cells and disrupt nucleic acid and protein synthesis.

It also helps control rapid fungal growth in certain wounds. At higher concentrations, it acts as a caustic agent, chemically burning (cauterizing) tissue to stop minor bleeding or remove warts and skin tags.
