Diabetic Foot Ulcers Aren’t Paper Cuts: When Triple Antibiotic Is Not Enough

This episode traces the history and science behind triple antibiotic ointment—its three ingredients (bacitracin, neomycin, polymyxin B), how they attack different bacteria, and why it became a household staple for minor cuts. It explains why diabetic foot ulcers are fundamentally different from everyday wounds—driven by neuropathy, poor blood flow, chronic inflammation, biofilm, and deeper infection—and why a topical ointment cannot address these underlying problems. The episode also covers risks of using ointment on diabetic ulcers (maceration, contact dermatitis, altered wound microbiome), the difference between colonization and infection, and the importance of prompt medical assessment, vascular evaluation, offloading, debridement, glucose control, and specialized wound care.
