When the First Antibiotic for Your Ear Infection Has Not Worked, and a Long-Haul Flight Is Coming
Patients walk into our clinic on Aldermans Hill expecting a 10 minute fix. Sometimes they leave with the answer to a question they did not know they needed to ask. This was one of those days. An adult patient returned for follow-up of a blocked ear that had not settled despite a previous course of antibiotics, with a long-haul flight in the diary in the near future. The diagnosis underneath was straightforward. The reason the first treatment had not worked was the right question. And the flight was not a footnote; it was the fulcrum of the management plan.
The presentation
A two-week history of one ear feeling blocked, beginning around Easter, suspected to have started with a small cut in the canal that became infected. An audiologist seen the previous week noted the eardrum appeared infected but could not see through to the ossicles, advising GP review. A different GP prescribed a course of antibiotics that improved the discharge and the pain. The tinnitus, the constant ringing, persisted. The sensation of blockage persisted. The patient described a feeling of “something behind the eardrum that cannot be accessed”.
The patient was due to fly long-haul in the near future for work, and was understandably worried about the condition deteriorating during the flight, particularly the risk of eardrum perforation during take-off and landing. Working in the travel sector, the patient was familiar with the calculus of in-flight medical events, and was asking the right question.
Why the first antibiotic did not work
The diagnosis on otoscopy today was unambiguous. Significant pus in the ear canal, consistent with otitis externa. The eardrum was partly visible, inflamed, but the pathology localised to the canal, not behind the drum. That is the key clinical point. Otitis media is behind the drum. Otitis externa is in the canal. The two share symptoms, and they do not share organisms.
The previous antibiotic had been prescribed in a class targeted at common upper respiratory pathogens. Those organisms are not the typical flora of the external ear canal. The improvement that the patient experienced on the first course was real but partial: the pain settled and the discharge improved, but the underlying canal infection did not resolve because the antibiotic class did not cover the relevant organisms in the relevant niche. NICE NG91, the antimicrobial prescribing guideline for otitis externa, frames the management here, and the recommendations are specific: a different antibiotic class for the canal flora, plus a topical antibiotic and steroid combination delivered to the canal directly.
Clinical anomaly: what was almost missed
First, what was almost missed. The diagnosis is not the issue. Otitis externa is a clinical diagnosis on otoscopy, and it was made today on otoscopy. What was almost missed is treatment-organism mismatch. A patient with persistent symptoms after a course of treatment can easily be told the infection is “just slow to settle”. The actual issue here was that the first antibiotic chosen was targeted at the wrong organisms. Repeating the same class, or extending it for longer, would have continued the mismatch. The right answer is escalation to a class that covers the canal flora, alongside a topical preparation that delivers antibiotic and steroid directly into the canal.
Second, where the standard NHS pathway would have gone. Standard primary care, on a busy day, can fall into the pattern of repeating or extending the same antibiotic when the first course has not resolved the symptoms. Same day private GP access here meant the time to re-examine carefully, the time to read the audiologist’s note in full, the time to explain why a different antibiotic class is being chosen, and the time to counsel for the flight in detail. The flight changes the calculus: an unresolved canal infection plus pressurised cabin air is a known combination for eardrum perforation. Same day access on the right day gives the patient several days of treatment before they fly, which is what makes the difference.
Third, what differentials were ruled out. Otitis media was reduced by otoscopy; the pus was visible in the canal, not behind the drum. A foreign body was excluded by direct visualisation. Cholesteatoma was kept on the differential and the ENT review threshold was lowered explicitly: if the new course does not resolve symptoms, ENT review is the next step, especially if hearing loss develops during or after the flight. A perforated drum from a forceful Valsalva manoeuvre was raised proactively as a counselling point, because the patient may try Valsalva on the flight and needs to know the risk.
The plan, in clinic, on the same visit
A new antibiotic class was prescribed for 10 days, targeting the canal flora. A topical antibiotic and steroid ear drop combination was prescribed, four drops in the affected ear twice daily. Drop technique was counselled in detail: lie on the affected side or wait several minutes after instillation, so that the drops reach the canal depth where they need to act. A clear safety net was agreed: ENT review if hearing loss develops, particularly during or after the flight.
The pre-flight counselling was the second half of the visit, and arguably the part that mattered most. Eardrum perforation is a real risk during take-off and landing, particularly with a canal infection that has not fully resolved. Analgesia is available on board, and good travel insurance is non-negotiable. The Valsalva manoeuvre, pinching the nose closed and gently blowing, can help equalise pressure across the eardrum, but it itself carries a small perforation risk and should be done gently, never forcefully. Long-haul carriers carry a medical team on board for in-flight assistance, and the patient was reassured that asking for help during the flight is the right thing to do, not an over-reaction.
What ear drops actually do, and how to use them properly
Topical antibiotic and steroid ear drops are designed to deliver medication directly to the inflamed canal. The antibiotic addresses the infection. The steroid reduces the canal swelling, which is what makes drops uncomfortable in the first 24 to 48 hours of treatment. Two practical points. First, the drops only work if they reach the right depth. Tilt the head, drop the prescribed number of drops, and remain in that position for several minutes, allowing the drops to track down the canal under gravity. Second, the canal swelling can make the first applications feel as if the drops are not getting in. They often are. Persistence in the first 48 hours is part of the treatment, unless pain is severe or new.
The Valsalva manoeuvre: useful, with a known risk
It is worth being clear. The Valsalva manoeuvre is a useful technique for equalising pressure across the eardrum during ascent and descent. It is also, in an inflamed and weakened eardrum, a manoeuvre that can produce a perforation if performed forcefully. The right counselling is to teach the technique, name the risk, and let the patient choose. Pinch the nose. Close the mouth. Gently blow. If pressure equalises with a small click sensation, stop. If it does not equalise, do not push harder. Yawning, swallowing, and chewing all help equalise pressure too, often more safely.
When to see a same day private GP for an ear infection
Several thresholds should move a patient towards a same day private GP appointment rather than waiting it out at home. Persistent ear pain, with or without discharge, that has not improved within 48 to 72 hours of starting a treatment. Persistent tinnitus or sensation of blockage after a course of antibiotics has been completed. Any hearing loss that does not resolve as the infection settles. Imminent travel, particularly long-haul, with an unresolved ear infection. Any history of cholesteatoma or recurrent ear infections in the same ear. The reason same day access matters in this picture is the timeline; an ear infection that needs a different antibiotic class and topical drops needs the change today, not in 6 days when the appointment becomes available.
