Wash and completely dry the affected area. Gently rub the medicine in until it is evenly distributed. The area may be left uncovered, or you may cover it with a sterile bandage. Wash your hands immediately after using Polysporin ointment, unless your hands are part of the treated area. Polysporin ointment works best if used at the same time each day. To clear up your infection completely, use Polysporin ointment for the full course of treatment. Keep using it even if you feel better in a few days. If you miss a dose of Polysporin ointment, use it as soon as you remember. Continue to use it as directed by your doctor or on the package label.
