Treatment for Open Sores from Diaper Rash in Babies

For open sores on your baby's bottom from diaper rash, use a barrier cream containing zinc oxide or petroleum jelly, keep the area clean and dry, and allow diaper-free time to promote healing. 1

Immediate Treatment Plan

1. Barrier Protection

  • Apply a thick layer of barrier cream containing zinc oxide or petroleum jelly to create a protective barrier between the skin and moisture
  • For open sores specifically, petroleum jelly (Vaseline) or dimethicone-based products work well to form a moisture barrier 2
  • Apply barrier cream after each diaper change to promote comfort and long-lasting protection

2. Cleaning Techniques

  • Clean the diaper area gently with mild cleanser or plain water
  • Pat dry thoroughly or allow to air dry completely before applying barrier cream 2
  • Avoid commercial baby wipes that contain alcohol or fragrances which can irritate open sores
  • Consider using emollient ointment for cleaning instead of water or commercial wipes 1

3. Diaper Management

  • Change diapers frequently (every 2-3 hours and immediately after bowel movements)
  • Use superabsorbent disposable diapers with gelling material in their core to keep moisture away from skin 3
  • Consider trimming the inner elastic of disposable diapers to reduce friction 1
  • Line the diaper with a soft cloth liner coated with emollient or petroleum jelly 1

4. Air Time

  • Allow for diaper-free time several times daily (15-20 minutes, 2-3 times per day)
  • Place baby on a clean towel or waterproof pad during this time
  • This helps the sores dry out and heal faster

For Persistent Sores (after 3 days of treatment)

If the sores don't begin to heal after 3 days of the above treatment:

Add Antifungal Treatment

  • Add an over-the-counter antifungal cream containing clotrimazole or miconazole
  • Apply a thin layer to affected areas, especially if you notice satellite lesions (small red spots separate from the main rash area) 3
  • Continue using the barrier cream on top of the antifungal cream

Consider Low-Potency Corticosteroid

  • A low-potency (1% hydrocortisone) cream can help reduce inflammation 3
  • Apply sparingly to affected areas twice daily for no more than 7 days
  • Always apply barrier cream over the corticosteroid cream

When to See a Doctor

Seek medical attention if:

  • The rash worsens or doesn't improve after 7 days of home treatment
  • The sores appear infected (increased redness, swelling, warmth, pus, or red streaks)
  • Your baby develops a fever
  • The rash spreads beyond the diaper area
  • Your baby seems to be in significant pain

Prevention Strategies

  • Change diapers frequently, especially after bowel movements
  • Clean and dry the diaper area thoroughly at each change
  • Apply barrier cream preventatively at each diaper change
  • Give regular diaper-free time
  • Avoid tight-fitting diapers and plastic pants
  • Consider switching diaper brands if you suspect sensitivity to dyes 4
  • Use dye-free diapers if allergic contact dermatitis is suspected 4

Common Pitfalls to Avoid

  • Don't scrub the affected skin when cleaning - pat gently instead
  • Avoid using talcum powder which can irritate the skin and has health concerns
  • Don't use adult products containing benzocaine or other numbing agents
  • Avoid using multiple products simultaneously which can further irritate the skin
  • Don't use harsh soaps or bubble bath products
  • Don't secure diapers too tightly which can cause friction and worsen the rash

By following these steps consistently, the open sores from diaper rash should begin healing within a few days. The key is creating a clean, dry environment with appropriate barrier protection to allow the skin to heal naturally.
