Debrox Dosing for Ear Wax Removal

For adults and children over 12 years: apply 5 to 10 drops into the affected ear twice daily for up to 4 days, keeping the drops in the ear for several minutes by tilting the head or placing cotton in the ear. 1

Specific Dosing Instructions

  • Tilt the head sideways and place 5 to 10 drops of Debrox (carbamide peroxide 6.5%) into the ear canal 1
  • Apply twice daily for up to 4 days 1
  • The tip of the applicator should not enter the ear canal 1
  • Keep drops in the ear for several minutes by maintaining head tilt or placing cotton in the ear 1
  • Children under 12 years should consult a doctor before use 1

Treatment Algorithm After Initial Drops

  • After 3-5 days of cerumenolytic treatment, if wax persists, proceed to irrigation with body-temperature water using a bulb syringe or large syringe 2, 3
  • The American Academy of Otolaryngology-Head and Neck Surgery found that cerumenolytic followed by self-irrigation at home is the most cost-effective protocol 2
  • Any wax remaining after the 4-day treatment period may be removed by gently flushing the ear with warm water using a soft rubber bulb ear syringe 1
  • If drops and irrigation both fail, manual removal by a healthcare provider is the third-line option 3

Absolute Contraindications - Do NOT Use If:

  • Perforated tympanic membrane (current or history of perforation) 2, 3
  • History of ear surgery (unless cleared by ENT) 2, 3
  • Tympanostomy tubes in place 3
  • Active otitis externa or ear infection 2, 3
  • Ear canal stenosis or exostoses 2, 3

Modifying Factors Requiring Caution

  • Patients on anticoagulant therapy require careful assessment 2, 3
  • Immunocompromised state warrants additional caution 2, 3
  • Diabetes mellitus may affect management approach 2, 3
  • Prior radiation therapy to head and neck requires consideration 2

Expected Outcomes and Safety Profile

  • Carbamide peroxide causes instant degradation of cerumen, with grade 3 degradation evident after 20 minutes at body temperature 4
  • The American Academy of Otolaryngology-Head and Neck Surgery notes that adverse effects are generally mild and rare, including transient hearing loss, dizziness, discomfort, or local skin irritation 2
  • No serious adverse effects have been reported with carbamide peroxide use 4

Critical Safety Points

  • Never use cotton-tipped swabs to remove wax, as they push cerumen deeper and can cause canal laceration, tympanic membrane perforation, and ossicular dislocation 2, 3
  • Strongly avoid ear candling due to lack of efficacy and potential for serious injury including burns and perforation 2, 3
  • Before irrigating after drops, obtain detailed history to identify contraindications, as the eardrum is frequently not visualized due to cerumen impaction 2
  • Use body-temperature water (37°C/98.6°F) for irrigation to avoid caloric effects causing dizziness 2, 3

When to Refer

  • If multiple treatment attempts with drops and irrigation are unsuccessful, refer to otolaryngology for manual removal with specialized equipment 2
  • Refer if contraindications to drops or irrigation are present 2
  • If symptoms persist despite resolution of impaction, evaluate for alternative diagnoses 2
