Parent Instructions for DeBrox (Carbamide Peroxide) Drops in Young Children

DeBrox drops should be used twice daily for up to 4 days, with 5-10 drops instilled per application while the child lies with the affected ear upward, remaining in this position for 3-5 minutes to ensure proper penetration. 1

Age-Specific Dosing and Safety

  • Children under 12 years require physician consultation before use 1
  • The American Academy of Otolaryngology-Head and Neck Surgery supports cerumenolytic use in children as young as 6 months, though evidence is strongest for children over 2 years 2
  • DeBrox (carbamide peroxide) is classified as a non-water, non-oil-based cerumenolytic that works through mechanisms not fully defined but appears effective for wax dissolution 2

Step-by-Step Application Instructions

Positioning

  • Have the child lie down with the affected ear facing upward 2
  • For young children who resist lying still, use a timer to mark the 3-5 minute waiting period—this helps facilitate cooperation 2

Drop Administration

  • Tilt the child's head sideways with the affected ear upward 1
  • Place 5-10 drops into the ear canal (the exact amount varies with the child's age and ear canal size) 1, 2
  • The applicator tip should NOT enter the ear canal—run drops along the side of the canal until filled 1, 2
  • Perform gentle to-and-fro movement of the outer ear (pinna) to eliminate trapped air and ensure the drops fill the canal completely 2
  • Alternative technique: use "tragal pumping" (gentle pressing on the tragus) to help drops penetrate deeper 2

Waiting Period

  • Keep the child's head tilted for 3-5 minutes after drop instillation 1, 2
  • You may place a cotton ball loosely at the ear opening to prevent drops from running out, but do NOT push it into the canal 1
  • After the waiting period, leave the ear canal open to dry—avoid trapping moisture 2

Treatment Duration and Follow-Up

  • Apply drops twice daily for up to 4 days 1
  • After completing the 4-day treatment course, any remaining wax may be removed by gently flushing the ear with warm water using a soft rubber bulb ear syringe 1
  • If wax persists after home treatment, professional removal may be necessary 2, 3

Critical Safety Warnings

Absolute Contraindications

  • Do NOT use if the child has active ear infection (otitis externa) 2
  • Avoid use if there is known ear drum perforation or ear drainage 2
  • Stop immediately if allergic reaction or severe irritation develops 2

What NOT to Do

  • Never use cotton-tipped swabs to clean the ear canal—they push wax deeper and can cause canal laceration, eardrum perforation, or damage to the tiny bones of hearing 2, 3
  • Do not use ear candles—they have no proven efficacy and can cause burns, canal occlusion, and eardrum perforation 2, 3
  • Do not insert bobby pins, paper clips, or any other objects into the ear canal 2

Expected Side Effects and When to Seek Help

Common, Mild Effects

  • Temporary discomfort, mild irritation, or slight pain may occur 2
  • Transient hearing loss (from the drops filling the canal) is normal and resolves after treatment 2
  • Brief dizziness can occur but should be minimal 2

When to Contact Your Doctor

  • If pain becomes severe or worsens 2
  • If skin irritation or rash develops around the ear 2
  • If symptoms persist after completing the 4-day treatment course 1
  • If the child develops fever, drainage, or signs of infection 2

Important Context About Effectiveness

  • No cerumenolytic agent (including DeBrox) has been proven superior to plain water or saline in clinical trials 2, 4
  • However, any cerumenolytic treatment is generally better than no treatment at all 2
  • Water-based agents like carbamide peroxide have the lowest risk of allergic skin reactions compared to oil-based products 2
  • Studies in children ages 6 months to 5 years showed no statistical difference between different cerumenolytic agents when followed by irrigation 2

Special Considerations

  • Children with hearing aids are at higher risk for wax impaction and may need regular professional ear checks 2, 3
  • If your child has diabetes, immunocompromised state, or abnormal ear canal anatomy, consult your physician before using any ear drops 3
  • Having another person administer the drops (rather than the child self-administering) significantly improves treatment adherence and effectiveness 2
