How to Use Debrox (Carbamide Peroxide) for Earwax Removal

Debrox (carbamide peroxide) ear drops should be used twice daily for up to four days, followed by gentle irrigation with warm water using a soft rubber bulb syringe if needed to remove softened earwax. 1

Proper Application Technique

For adults and children over 12 years of age:

  1. Preparation:

    • Allow drops to reach room temperature
    • Wash hands thoroughly before application
  2. Application:

    • Tilt head sideways with affected ear facing up
    • Place 5-10 drops into ear canal
    • Keep the applicator tip from entering the ear canal to prevent contamination
    • Maintain head tilted position for several minutes to allow drops to penetrate
    • Optionally place cotton in ear to prevent drops from leaking out
  3. Treatment Schedule:

    • Use twice daily for up to four days 1
    • After treatment period, any remaining softened wax can be removed by gently flushing the ear with warm water using a soft rubber bulb ear syringe

Effectiveness and Mechanism

Carbamide peroxide works by releasing oxygen when it comes in contact with earwax, creating a foaming action that helps break down and soften impacted cerumen 2. This chemical action makes the wax easier to remove either naturally or through gentle irrigation.

Research shows that:

  • Carbamide peroxide produces visible degradation of earwax almost immediately upon contact 3
  • Water-based cerumenolytics like carbamide peroxide have success rates of 5-22% when used alone 2
  • When followed by irrigation, success rates increase to 68-92% 2

Important Precautions

  • Do not use if:

    • You have ear pain
    • Discharge from the ear
    • Ear injury or perforation
    • Had ear surgery
    • Have ear tubes 4
  • Stop use and consult a doctor if:

    • Irritation or pain develops
    • Symptoms persist after 4 days of treatment
  • Children under 12 years: Consult a doctor before use 1

Common Mistakes to Avoid

  1. Never insert cotton swabs or other objects into the ear canal - This can push wax deeper and cause impaction or injury 2

  2. Avoid using alcohol-based solutions - These can be painful and potentially ototoxic if the tympanic membrane is not intact 4

  3. Don't use if tympanic membrane is perforated - Cerumenolytics can enter the middle ear and cause infection 4

  4. Don't skip the irrigation step - Using drops alone may not completely remove impacted wax; gentle irrigation after softening is often necessary 2

  5. Don't use water that's too hot or cold - Water for irrigation should be body temperature to prevent dizziness 4

Follow-up and Prevention

  • If symptoms persist despite treatment, seek professional evaluation as other conditions may mimic earwax impaction 4

  • For prevention of recurrent impaction, monthly application of carbamide peroxide drops followed by gentle irrigation may be recommended 2

  • Remember that some earwax is normal and protective - only treat when symptoms are present or when wax is visibly obstructing the ear canal 2
