a topical antiseptic.

indications A 1% solution was traditionally prescribed for the prevention of gonococcal ophthalmia in newborns, but povidone iodine is now usually used because it is less expensive and has a broader spectrum of action. Stronger concentrations can also be used on wet dressings for cauterizing wounds, removal of granulation tissue and warts, and prophylaxis following burns.

adverse effects Among the more serious adverse effects are severe local inflammation, burns, and argyria, and staining.
