Triple antibiotic ointment is a topical medication that prevents and treats minor bacterial skin infections due to scrapes, burns and small cuts, says WebMD. Individuals apply it themselves, and it does not require a prescription.
The active ingredients in triple antibiotic ointment are bacitracin, polymyxin and neomycin, according to Drugs.com. All of these ingredients are antibiotics that individuals use for first aid treatment. It is only effective as a topical treatment.
Before applying the ointment, wash hands thoroughly, instructs WebMD. Clean and dry the affected area on the skin before applying a small amount of the ointment. Bandage the area if desired, and wash hands after applying the ointment. Apply the triple antibiotic ointment one to three times a day.
