Why the doctor may not prescribe antibiotics for your child’s ear
A child with earache, a fever and a bad night is the commonest reason a parent expects an antibiotic and is surprised not to get one. It is worth explaining properly rather than leaving it as a doctor's whim, because the evidence behind it is strong and the decision is made on defined criteria.
Most acute middle ear infections resolve without antibiotics. The eardrum is inflamed behind the pain, the immune system deals with it, and the majority of children are better in two to three days regardless of what is prescribed. Antibiotics shorten the illness modestly in the average case, and bring diarrhoea, rash and thrush in a meaningful minority.
So guidelines, led by the American Academy of Pediatrics, set out **watchful waiting** for 48 to 72 hours in non-severe disease where follow-up is reliable — with the crucial condition that pain is treated properly throughout.
Non-severe means: mild ear pain present for less than 48 hours, temperature under 39°C, and no discharge from the ear.
By age, watchful waiting is appropriate for children **6 to 23 months with infection in one ear only**, and for children **24 months and older with one or both ears** affected, provided in each case the illness is non-severe.
The practical mechanism is the **delayed prescription** — sometimes called a safety-net prescription. You leave with the antibiotic in hand and instructions not to start it, then fill it only if your child is not improving, or is getting worse, at 48 to 72 hours. It gives the illness a chance to resolve on its own without leaving you stuck if it does not. The AAP's own journals note that watchful waiting remains under-used in practice, largely because it takes longer to explain than to prescribe.
None of this means an ear infection is nothing, or that you should stay home and hope. It means the antibiotic decision is made on criteria, and that being examined is what determines which side of them your child falls.
When antibiotics are given without waiting
The criteria run the other way too, and these children are treated straight away.
Antibiotics are indicated when the illness is **severe**: a temperature of **39°C or above**, moderate-to-severe ear pain, or ear pain that has already lasted **48 hours or more**.
They are also given without waiting for **infants under 6 months**, who are outside the watchful-waiting discussion entirely. A baby under six months with a suspected ear infection is assessed and treated, not observed, and any fever under three months of age needs same-day assessment regardless of the ears.
Immediate treatment also applies where there is **discharge from the ear**, indicating the drum has perforated; where **both ears** are affected in a child aged 6 to 23 months; where the child has an underlying condition such as immunodeficiency, cleft palate or Down syndrome; and where reliable follow-up is not achievable — if you cannot easily get back to a clinic in 48 hours, waiting is not the right strategy for your family.
If an antibiotic is prescribed, complete the course even after your child brightens up on day two, which they usually do.
Come back sooner than planned if there is swelling or redness **behind** the ear, if the ear looks pushed forward, if there is new facial weakness, severe headache, neck stiffness, drowsiness or repeated vomiting. Those suggest spread beyond the middle ear — mastoiditis or worse — and need urgent assessment rather than a scheduled review.
Treating the pain, which matters more than parents are told
Whether or not an antibiotic is given, pain relief is the part that actually changes your child's night, and it is routinely under-done.
Give paracetamol or ibuprofen at the correct weight-based dose, and give it **regularly** for the first day or two rather than waiting for the crying to restart. Under-dosing is common, usually because the dose was calculated for a younger, lighter child months ago. Check it against current weight.
A warm compress held against the ear helps. Keeping the child slightly upright, including propping the head of the cot mattress rather than the pillow, often eases night pain.
Do not put oil, breast milk, onion juice or any traditional preparation into the ear canal. If the eardrum has perforated — and you may not know it has — introducing anything into the middle ear risks real harm. This comes up often enough locally to be worth stating plainly rather than politely.
Do not use cotton buds. They push wax inward, and in an already inflamed ear they can perforate the drum.
Ear drops for pain are not a substitute for oral analgesia, and must not be used if there is any discharge or suspected perforation.
Keep the ear dry while it is infected — no swimming, and take care in the shower.
If your child suddenly stops complaining and you find fluid or pus on the pillow, that is usually the drum perforating. It is alarming to see and it typically relieves the pain immediately, and it needs review rather than panic: most heal, but it should be checked, and the ear must be kept dry.
Glue ear, and the hearing problem that hides behind it
After an ear infection settles, fluid frequently remains behind the eardrum. This is otitis media with effusion — glue ear — and it is not an infection. It causes no pain and no fever, and it commonly persists for weeks or a few months before clearing on its own.
What it does cause is **hearing loss**, typically mild to moderate, and that is where the harm sits. A child who cannot hear clearly does not usually say so. Instead they turn the television up, ask "what?" repeatedly, seem inattentive, fall behind in class, or become frustrated and badly behaved. Glue ear is a well-recognised and frequently missed cause of apparent behaviour and learning problems in young children.
Because it usually resolves, the standard approach is a period of watchful waiting with a hearing assessment rather than immediate intervention. Antibiotics do not clear it. Decongestants and antihistamines do not clear it. Where it persists beyond about three months with demonstrable hearing loss, or where speech and language development is being affected, referral to ENT is appropriate — grommets are the usual next step and they work.
Two things reduce recurrence and are worth acting on. Avoid smoking anywhere near the child; second-hand smoke is one of the strongest modifiable risk factors for recurrent middle ear disease. And do not feed a baby lying completely flat.
If your child has had repeated infections or you suspect they are not hearing well, ask for a hearing check rather than assuming it will sort itself out. We can arrange assessment.
Adults, swimmer’s ear, and when it is not the middle ear at all
Middle ear infection is far less common in adults, and when it happens the question of *why* matters more than in children.
Persistent one-sided middle ear fluid in an adult, particularly with hearing loss and no preceding cold, is not something to treat and forget. It needs examination of the nasopharynx, because a blockage at the back of the nose can cause it — and in this region, nasopharyngeal carcinoma is a recognised cause that presents exactly this way. It is uncommon, it is treatable when found early, and it is missed when one-sided ear fluid in an adult is dismissed. Add a persistent neck lump, one-sided nasal blockage or blood-stained nasal discharge and it becomes urgent.
Most adult ear pain, though, is **otitis externa** — infection of the ear canal rather than the middle ear. It is common in this climate, and it behaves differently: the outer ear is tender to touch, pulling on the earlobe hurts, the canal is swollen and often itchy, and there may be discharge, but hearing is affected mainly by swelling rather than by fluid behind the drum.
Otitis externa is driven by moisture and by damage to the canal skin. Swimming, humidity, and above all cotton buds — which strip the protective wax layer and scratch the skin — are the usual causes. Treatment is topical ear drops, keeping the canal dry, and stopping whatever is traumatising it. Oral antibiotics are usually unnecessary. Diabetic and immunosuppressed patients need lower thresholds for review, because a severe form of this infection can spread to bone.
The simplest prevention: nothing smaller than your elbow goes into your ear. Wax protects the canal, migrates out naturally, and does not need removing unless it is causing symptoms.
