What is polysporin?

Polysporin is a brand of over-the-counter antibiotic ointment that is used to prevent and treat bacterial infections of the skin. The active ingredients in Polysporin are polymyxin B sulfate and bacitracin zinc, both of which are antibiotics that work to kill bacteria. It comes in various forms, such as ointment, cream, and eye and ear drops, and is commonly used for wound care, burns, cuts, and other skin infections. Polysporin is intended for external use only and should not be ingested or used on open wounds that are deep or punctured. It is available without a prescription in most pharmacies. As with all medications, it is important to read and follow the instructions on the label, and to consult a healthcare professional if there are any concerns or questions about its use.
