Application Tips

How Much to Use

  • Apply a thin layer that just covers the wound
  • The ointment should appear as a light coating, not a thick glob
  • A small amount (about the size of the wound) is typically sufficient
  • More ointment does not mean faster healing or better protection

Proper Technique

  1. Always start with clean hands — Wash thoroughly with soap and water
  2. Clean the wound first — Remove debris and bacteria before applying antibiotic
  3. Use clean applicators — If concerned about contaminating the tube, use a cotton swab
  4. Don’t touch the tube tip to the wound — This can contaminate the ointment
  5. Replace cap immediately — Keep the product clean for future use

Bandaging

  • Small cuts in clean areas may not need a bandage
  • Cover wounds that:
    • Are in areas prone to dirt or friction
    • Are on hands or feet
    • May get wet
    • Are still bleeding slightly
  • Change bandages daily or when wet/dirty

Do not use bacitracin for extended periods without medical guidance. Prolonged use may:

  • Increase risk of allergic sensitization
  • Delay identification of wounds that need medical attention
  • Contribute to antibiotic resistance

  • Ensure children don’t put treated fingers in mouth
  • Same dosing as adults—thin layer to affected area

  • Monitor for allergic reactions, which may be more common with age
