Triple Antibiotic Ointment Application Frequency for Burns
Triple antibiotic ointment should be applied to minor burns 1-3 times daily with dressing changes until the burn is healed. 1, 2, 3
Recommended Application Protocol
- After initial cooling of the burn with clean running water for 5-20 minutes, gently clean the wound with tap water or isotonic saline 2, 4
- Apply a thin layer of triple antibiotic ointment (containing neomycin, polymyxin B, and bacitracin) directly to the burn 3, 5
- Cover with a clean, non-adherent dressing such as Xeroform, Mepitel, or gauze 2, 3
- Change the dressing and reapply the ointment 1-3 times daily, depending on wound characteristics 2, 6
- For small partial-thickness burns being managed at home, petrolatum-based antibiotic ointment should be applied with each dressing change 1
Evidence Supporting Triple Antibiotic Ointment Use
- Triple antibiotic ointment is active against the most common disease-causing pathogens found in wounds and on the skin 5
- In studies comparing treatment options, triple antibiotic ointment enhanced reepithelialization and reduced scar depth and contraction compared with silver-based foam dressings 6
- The formulation containing neomycin, polymyxin B and bacitracin in a petrolatum base provides both antimicrobial protection and maintains a moist wound environment 5, 6
Considerations Based on Burn Severity
For Superficial (First-Degree) Burns:
- Apply triple antibiotic ointment 1-2 times daily with a clean, non-adherent dressing 1, 3
- Continue application until the burn is healed, typically 3-7 days 2
For Partial-Thickness (Second-Degree) Burns:
- Apply triple antibiotic ointment 2-3 times daily with dressing changes 2, 6
- Wounds treated with topical antibiotic ointment should appear moist at each dressing change 6
- Continue application until complete reepithelialization, typically 10-21 days 6
Important Cautions
- Do not apply ice directly to burns as this can cause further tissue damage 2, 4
- Do not apply butter, oil, or other home remedies to burns 2, 4
- Do not break blisters, as this increases infection risk 2
- Topical antibiotics should not be used as first-line treatment for large or infected wounds but should be dedicated to preventing infection in minor burns 1, 2
- Routine systemic antibiotic prophylaxis is not recommended for burns patients 1, 7
When to Seek Medical Attention
- Seek immediate medical care for burns that involve the face, hands, feet, or genitals 1, 2
- Seek immediate medical care for partial-thickness burns covering >10% body surface area (>5% in children) 1, 2
- Seek immediate medical care for all full-thickness (third-degree) burns 2, 4
- Seek immediate medical care for burns showing signs of infection or that are very painful 2, 4
