    Can anybody direct me to some info/posts re the use of Silver Nitrate 75% on the treatment of VPs?

    Hi there,

    Personally i have found sillver nitrate to be more effective in the treatment of hard corns than VPs as its application can be exact and penetrate deep hyperkeratotic tissue. I often opt for the use of 60% salicylic acid for VPs as in my opinion it provides a better outcome. None the less, i would take into consideration site, size, pain threshold and social factors. Hope you find what you need. Thanks

    Kirsty :)

    Blue 123,

    Not found it effective on clearing VP’s but handy tool for cauterising and for small amount of hyper-granulation, don't use on corns myself as can be very painful.


    Hazard Corrosive substance

    Health Risks Use gloves, eye protection and wear plastic apron.

    Spillage Wash area thoroughly with water after transferring spillage into containers of water to dissolve then run to waste.

    First Aid
    Inhalation - remove to fresh air. If breathing difficulties give oxygen and seek medical attention.

    Eyes - Wash thoroughly with water or Saline solution. Obtain medical attention.

    - Wash affected area with soap and water. Remove contaminated clothing. Obtain medical attention.

    - Wash mouth thoroughly with water and give plenty of water to drink. Obtain medical advice.

    Extinguisher media - any

    Risk Assessmen
    t Used as caustic in treatment of granulation tissue, warts etc.

    It`s a protein precipitant, not anti-viral. Thus, pretty useless for VP`s unless you`re going for the placebo effect (which I sometimes do for kids).

    Mode of action of silver nitrate does render it as anti-bacterial. It is well documented that silver ions can inhibit growth of both gram positive and negative bacteria. These ions, combined with chloride in the skin form silver chloride, resulting in the brownish eschar....but there is stops. Unless used on broken skin. Which smarts, but does produce an obvious inflammatory reaction. So COULD, in theory, induce resolution of the VP.

    I reckon the myth of efficacy in VP treatment stems from it`s application to reduce granulation tissue, including warts. Pt observes `change` in wart appearance = believes it is `working`.....

    Hi all, I've been looking around for direction as to the toxicity of silver nitrate when applied to skin. There isnt many hard and fast guidelines (even on product information) for the applicator sticks (we use 75%) and I was wondering if there was any possibility of getting a toxicity reaction from repeated use of the applicator sticks to isolated problem HDs? In managing deep and resistent HDs in deformed feet (once all pressure reducing avenues have been exhausted) could a 2-monthly application of silver nitrate following enucleation (which I have found particularly useful for certain patients) accumulate over time or am I being too cautious!?
    Thanks for any advice,

    As blinda has stated the protein precipitant (eschar) discolours in the presence of light which gives a better opportunity to observe the pattern of the skin's striations. This allows easier identification and of a circumscribed lesion (VP) as opposed to a rudely interrupted destruction more consistent with pressure and shearing stress. Hence the Agno3 application to the skin aids a differential diagnosis only.

    houseThe application of silver nitrate post enucleation is commonly used to form an eschar which helps with subsequent scalpel work (usually within 21 days). Protein precipitant help firm up maceration post enucleation and can be used very successfully on interdigital lesions as well as fibrous corns. Although stypic pencils (which usually contain high percentages of silver nitrate) are in common use in boxing to stem blood flow particularly over the eyes, authors like PJ Read cautioned against using silver nitrate over broken skins on the foot because of the risk of infection. Whilst there is no actual evidence to support this other than perhaps anecdotal it may be the resultant eschar might prevent healing by first intention and therefore increase the risk of contamination.
