Antibiotic ointments are topical medications used to treat bacterial infections. They contain antibiotics, which are medications that kill or stop the growth of bacteria. Applying an antibiotic ointment directly to the affected area can help prevent the spread of infection and speed up healing. These ointments are often used for minor cuts and scrapes, burns, and other skin conditions that have opened the skin barrier and are at risk for infection. They come in various forms, including creams, gels, and ointments, and are available over-the-counter or by prescription. Some common types of antibiotic ointments include bacitracin, neomycin, and polymyxin B.
