How to Change a Diabetic Foot Ulcer Dressing at Home: Step-by-Step

Home dressing changes are safe when patients and caregivers follow a consistent sequence. This guide focuses on the mechanics of the change itself — a distinct question from the daily dry-observe-cover-seal routine.

Before you start

• Wash hands for 20 seconds with soap and water.
• Lay out supplies: clean gauze, saline or prescribed cleanser, hypoallergenic paper tape, disposable gloves, a plastic bag for used materials.
• Sit in a well-lit spot with the foot supported. Never change a dressing on a dirty floor or bed.

The step-by-step change

1. Glove up and loosen the old tape gently, pulling toward the wound so you don't tear fragile edges.
2. Lift the old dressing straight up. If it sticks, moisten it with saline first — do not yank.
3. Inspect what came off. Note drainage color, amount, and odor; take a photo if your clinician has asked you to.
4. Cleanse with saline or the solution your clinician prescribed. Do not use hydrogen peroxide or alcohol — they damage healing tissue.
5. Pat dry with clean gauze, including between the toes.
6. Apply the new dressing flat and smooth, sized to the wound with a small border.
7. Seal the edges with paper tape, leaving the center free so drainage can be seen.
8. Bag and discard old supplies; wash hands again.

When to stop and call the clinic

• Bleeding that soaks through gauze
• New black, gray, or green tissue
• Foul odor, spreading redness, or fever
• Sudden increase in pain or drainage

Clinicians reviewing home-change photos between visits can track subtle changes with a healing dashboard, and mobile teams can capture and chart each visit in the field with WoundScribe On Wheels for mobile providers.
