Topical antibiotics are medications applied directly to the skin to treat bacterial infections. They work by killing bacteria or inhibiting their growth, helping to prevent infections in minor cuts, scrapes, and burns. Common examples include bacitracin, neomycin, and mupirocin. These antibiotics are typically available over-the-counter or by prescription, depending on their strength and intended use. While effective for localized infections, they should be used as directed to avoid potential side effects, such as skin irritation or allergic reactions. Always consult a healthcare professional if unsure about their use.
