PDI - Povidone-Iodine Swabsticks Triples (3 swabs per pack) is a first aid antiseptic to help prevent the risk of skin infection in minor cuts, scrapes, and burns. Used in the preparation of the skin prior to surgery these PDI swabsticks scrub away dead skin, dirt, and oil from the effected area. Saturated with 10% USP povidone-iodine prep solution (equivalent to 1% available iodine), this swabstick provides longer germicidal activity than regular iodine.
