Tympanic Membrane Perforation with Suspicious Discharge: What to Do When Initial Antibiotic Therapy Did Not Work

This protocol addresses the patient with a tympanic membrane perforation producing discharge suspicious of middle ear infection — with no penicillin allergy — who has not shown the expected clinical response to first-line treatment within 48–72 hours.

Clinical Scenario

Tympanic membrane perforation with discharge suspicious of middle ear infection in a patient with no penicillin allergy. Initial management including aural microsuction, ciprofloxacin ear drops, and an amoxicillin course has already been undertaken.

Why This Protocol Applies — Previous Treatment Did Not Reach Its Goal

The first-line regimen — Ciprofloxacin ear drops combined with Amoxicillin — was expected to produce clinical response of the middle ear infection within 48–72 hours. Where that response has not occurred, escalation to the next step is indicated.

Escalation Approach (Partial Overview)

When initial amoxicillin has not produced the expected response, the next step involves adding clavulanate — moving to an oral combination antibiotic regimen. Complete dosing, duration, and clinical guidance are detailed in the full structured protocol.

If discharge suspect middle ear infection, require MCS and micro-suction then Ciprofloxacin 0.3% ear drops 5 drops BD, as well as Amoxicillin (15mg/kg) up to 500mg orally 8 hourly for 5 days.

If no response to amoxicillin within 48-72 hrs (suspect Haemophilus influenzae or Moraxalla catarralis) add clavulanate: Amoxicillin+Clavulanate 22.5+3.2mg/kg up to 875+125mg orally 12 hourly for 5 to 7 days.
