UNDESIRABLE EFFECTS
Skin and subcutaneous tissue disorders
Chronic application of silver nitrate or its products to conjunctive,
mucous
membranes or open wounds may lead to a condition known as argyria, an
accumulation of silver metal or compounds in the connective tissues
which gives rise
to a local or general bluish-black appearance. This is thought to be a
completely
harmless cosmetic effect only, but it may persist indefinitely or
disappear only very
slowly.
Absorption of nitrate following reduction of nitrate by certain
bacteria in some
wounds may cause methaemoglobinaemia.
