Treatment of Blocked Ear
The treatment depends on the cause: if the blockage is from earwax (cerumen impaction), use cerumenolytic ear drops (such as carbamide peroxide or oil-based drops) for 3-5 days followed by irrigation or manual removal if needed; if symptoms suggest infection (otitis externa) rather than wax, use topical antibiotic drops instead. 1
Step 1: Determine the Cause of Blockage
The first critical step is identifying whether the blocked ear is due to:
- Cerumen (earwax) impaction - characterized by decreased hearing, fullness, tinnitus, or changes to hearing aid function 1
- Otitis externa (ear canal infection) - presents with ear pain, drainage, itching, or tenderness 1
- Other causes - fluid behind the eardrum (otitis media), sudden hearing loss, or eustachian tube dysfunction 1
Seek immediate medical evaluation if you have ear pain, drainage, or bleeding, as these are NOT typical symptoms of simple wax impaction and require different treatment. 1
Step 2: Treatment for Cerumen Impaction (Earwax Blockage)
Home Treatment with Cerumenolytic Drops
For adults and children over 12 years, apply 5-10 drops of carbamide peroxide (Debrox) or hydrogen peroxide twice daily for up to 4 days. 2, 3
Proper administration technique is critical (only 40% of patients do this correctly): 4
- Tilt head sideways with affected ear upward 2, 3
- Fill the ear canal completely with drops 4
- Keep head tilted for 3-5 minutes to allow penetration 4, 5
- Perform gentle to-and-fro movement of the outer ear to eliminate trapped air 4, 5
- Do NOT insert the applicator tip into the ear canal 2, 3
Alternative options include oil-based drops (olive oil, almond oil) or water-based solutions (sodium bicarbonate), though evidence shows no clear superiority of one type over another. 6
When Home Treatment Fails
If drops alone don't clear the wax after 4 days, seek medical attention for professional removal. 1 The clinician can perform:
- Irrigation with warm water using a bulb syringe (only after softening with drops) 6
- Manual removal with appropriate instruments under direct visualization 1, 5
- Aural toilet (professional cleaning) if the canal is obstructed 1, 5
Critical Warnings for Cerumen Treatment
Do NOT use these methods if you have: 1
- Had previous ear surgery
- A perforated eardrum
- Tympanostomy tubes in place (unless cleared by your ENT surgeon)
Never use ear candles - they provide no benefit and can cause serious harm including burns, canal obstruction, and eardrum perforation. 1
Avoid cotton swabs - they push wax deeper and can cause impaction, canal trauma, or eardrum perforation. 1
Step 3: Treatment for Otitis Externa (Infected Ear Canal)
If the blockage is accompanied by pain, drainage, or signs of infection:
Use topical antibiotic ear drops (ofloxacin or ciprofloxacin-dexamethasone) twice daily for 7-10 days as first-line treatment. 1, 4
Administration technique for antibiotic drops: 1, 4
- Have another person administer drops if possible 4
- Lie with affected ear upward 1
- Fill ear canal completely 1
- Stay in position for 3-5 minutes 1, 4
- Press the tragus (cartilage flap in front of ear) in and out to help drops penetrate 1
Keep the ear dry during treatment - avoid swimming and use cotton with Vaseline to protect during bathing. 1, 4
Do NOT use oral antibiotics for uncomplicated otitis externa - they are ineffective, promote resistance, and cause unnecessary side effects. 4
When to Seek Medical Attention
Return to a clinician if: 4
- No improvement after 48-72 hours of proper treatment
- Worsening symptoms
- High fever or spreading redness
- Drops don't easily enter the ear canal (suggests obstruction needing professional cleaning)
- Drainage continues more than 7 days 1
Step 4: Special Populations
Children under 12 years: Consult a doctor before using over-the-counter cerumenolytic drops. 2, 3
Patients with tympanostomy tubes: If the tube is blocked, hydrogen peroxide can be used to clear it (85% success rate), but this should be done under medical supervision. 7
High-risk patients (diabetic, immunocompromised): Require closer monitoring and may need earlier medical intervention. 5
Common Pitfalls to Avoid
- Undermedicating as symptoms improve - complete the full treatment course 4
- Missing the ear canal when administering drops - proper positioning is essential 4
- Allowing water exposure during treatment - this promotes bacterial growth 4
- Discontinuing treatment early - use drops for the full prescribed duration even if symptoms resolve 4
- Overcleaning ears - excessive cleaning irritates the canal and increases impaction risk 1
What NOT to Do
Never insert foreign objects into the ear canal - this includes cotton swabs, bobby pins, keys, or any object smaller than your elbow, as they cause trauma and worsen impaction. 1
Most people do not need routine ear cleaning - earwax is protective and naturally expelled; only treat if symptomatic or obstructing. 1
