Recommended Usage of Debrox (Carbamide Peroxide) Ear Drops

For adults and children over 12 years of age, Debrox (carbamide peroxide) ear drops should be used by tilting the head sideways, placing 5-10 drops into the ear canal, keeping the drops in for several minutes, and using twice daily for up to four days. 1

Administration Instructions

  • Tilt head sideways with the affected ear facing up 1
  • Place 5 to 10 drops into the ear canal, ensuring the applicator tip does not enter the ear canal 1
  • Remain in this position for 3 to 5 minutes to allow the drops to penetrate the ear canal (using a timer may be helpful) 2, 1
  • A gentle to-and-fro movement of the ear or pressing with an in/out movement on the tragus (small piece of cartilage in front of the ear) can help the drops reach their intended destination 2
  • After waiting, you may get up and wipe off any excess drops 2
  • Use twice daily for up to four days if needed 1

After Treatment

  • Any wax remaining after treatment may be removed by gently flushing the ear with warm water using a soft rubber bulb ear syringe 1
  • Do not attempt to clean the ear yourself with cotton swabs or other objects as this may damage the ear canal or eardrum 2

Important Precautions

  • For children under 12 years of age, consult a doctor before use 1
  • Do not use if you have an active ear infection, dermatitis of the ear canal, or a perforated eardrum 2
  • Avoid use if you have had allergic reactions to any component of the product 2
  • Keep the ear dry during treatment 2
  • If you taste the ear drops, it may indicate a hole or perforation in the eardrum - inform your doctor 2

Effectiveness and Mechanism of Action

  • Debrox contains carbamide peroxide (urea-hydrogen peroxide), which is classified as a non-water, non-oil-based cerumenolytic agent 2
  • Cerumenolytics work by disintegrating earwax through hydration and fragmentation of corneocytes within the cerumen 2
  • Evidence suggests that cerumenolytic agents are generally more effective than no treatment for removing ear wax 3
  • However, studies have not consistently demonstrated that one cerumenolytic agent is superior to another, and some research indicates that saline or water alone may be as effective as commercial preparations 2, 4

Potential Side Effects

  • Cerumenolytic agents are generally well-tolerated with minimal side effects 2
  • Some people may experience local rash, itching, irritation, or discomfort 2
  • Rare side effects may include dizziness, unpleasant smell, tinnitus, or temporary hearing loss 3
  • If drops become painful or you develop unexpected symptoms, contact your doctor 2

When to Seek Medical Attention

  • If symptoms persist after the recommended treatment period of four days 1
  • If you experience severe pain, dizziness, or hearing loss 2
  • If you have a history of ear surgery, perforated eardrum, or ear tubes 2
  • For children under 12 years of age, as they require medical supervision 1

Remember that while Debrox and other cerumenolytics can be effective for many cases of earwax buildup, some patients may require professional ear irrigation or manual removal by a healthcare provider for complete resolution 2.
