Ear infections are one of the most common reasons parents take young children to the GP, and one of the conditions where the antibiotic prescribing debate is most practically relevant. The majority of acute middle ear infections in children are caused by bacteria and would theoretically respond to antibiotics — yet the evidence shows that most resolve without them, and the benefit of antibiotics for most children is modest at best while the harms of overuse (antibiotic resistance, disruption of gut microbiome) are real.
Understanding when ear infections require treatment, how to manage them at home, and what the indicators are for when antibiotics genuinely help allows parents to navigate GP appointments and treatment decisions with appropriate expectations.
Healthbooq provides parents with evidence-based guidance on common childhood illnesses and the evidence base for when treatment is and isn't needed.
What an Ear Infection Is
Acute otitis media (AOM) is infection and inflammation of the middle ear — the space behind the eardrum. It typically follows a viral upper respiratory infection: the virus causes swelling of the Eustachian tube (which connects the middle ear to the back of the throat), trapping fluid in the middle ear, where it becomes infected. In young children, the Eustachian tube is shorter and more horizontally oriented than in adults, which makes it easier for fluid and infection to travel upward — explaining why ear infections are so common in this age group.
In babies who are not yet verbal, the signs of an ear infection may be non-specific: irritability, difficulty sleeping, pulling or batting at the ear (though this is an unreliable sign in isolation, as babies handle their ears for many reasons), fever, and general unwellness following a cold. Older toddlers may report ear pain or complain about noise.
The Evidence on Antibiotics
Multiple randomised controlled trials and systematic reviews have assessed whether antibiotics improve outcomes in acute otitis media. The findings are consistent: for most children over two years with one-sided infection and no perforation, antibiotics provide a small reduction in duration and severity of symptoms compared to placebo, but the majority of children in both groups recover without complications. Given this modest benefit, UK guidance (NICE guideline NG91) recommends a "watchful waiting" approach for most children — managing pain, monitoring for deterioration, and prescribing antibiotics only when needed.
Antibiotics are recommended without delay for: children under two years with bilateral (both ear) infection; children with ear discharge (otorrhoea) indicating perforated eardrum; children who are systemically very unwell; and those with symptoms worsening or not improving after forty-eight to seventy-two hours of watchful waiting. Many GP practices provide a delayed prescription — a prescription to be filled only if symptoms have not improved within forty-eight to seventy-two hours — which has been shown to reduce antibiotic use without worsening outcomes.
Pain Management
Adequate pain relief is the most important immediate management, regardless of whether antibiotics are prescribed. Paracetamol and ibuprofen at appropriate doses for age and weight are effective for ear pain and fever. Ibuprofen may have slightly better analgesic effect for ear pain specifically. Olive oil ear drops are sometimes recommended for ear discomfort but have no evidence of benefit for otitis media specifically.
Glue Ear
Glue ear (otitis media with effusion) is a separate condition from acute ear infection: it involves persistent fluid in the middle ear that is not infected but causes hearing loss. It is very common in young children — affecting around thirty percent at some point — and typically resolves spontaneously within three months. Persistent glue ear causing significant hearing loss may require grommets (small tubes inserted into the eardrum to allow fluid to drain). Speech and language development should be monitored in children with confirmed glue ear, as hearing loss affects language acquisition.
Key Takeaways
Acute otitis media (middle ear infection) is one of the most common bacterial infections in young children, affecting around four in five children at least once before age five. In most healthy children over two years, it resolves within three to four days without antibiotics. NICE guidance recommends a watchful waiting approach for most children, with antibiotics reserved for children under two, those with bilateral infection, those with discharge, or those who are not improving after forty-eight to seventy-two hours. Pain relief with paracetamol and/or ibuprofen is the most important immediate management.
