Wound infections are treated with Puradine M ointment. An antimicrobial called Puradine M Ointment is used to treat and prevent wound infections. By killing and stopping the growth of bacteria that cause infections, Puradine M Ointment keeps cuts, abrasions, and other skin breaks from becoming infected. The gradual release of iodine is what gives it its antibacterial properties. Use the medication as directed by your physician and keep the afflicted region clean.
