A clinical trial published in the New England Journal of Medicine has found that the antibiotic azithromycin did not reduce wheezing symptom severity compared to a placebo in young children treated in emergency departments.
The AZ-SWED trial examined whether azithromycin — a commonly prescribed antibiotic — helps preschool-age children treated in emergency departments (EDs) for wheezing episodes. According to the New England Journal of Medicine (NEJM), children in this age group are frequently given antibiotics during these visits, yet earlier studies have not consistently shown benefit from azithromycin in this population.
Wheezing in young children — a whistling or rattling sound when breathing, often linked to viral infections or early asthma — is one of the more common reasons families bring toddlers to emergency departments. But whether antibiotics actually help in these cases has long been debated among clinicians.
The NEJM summarised the trial’s findings in a short video format, described as a Quick Take. The trial found no meaningful clinical benefit from azithromycin over placebo, with the results not supporting its routine use in this setting.
For parents in Kent, the practical takeaway is straightforward: if your child is wheezing, seek medical advice rather than assuming antibiotics are needed. The NHS advises that most wheezing in young children is caused by viruses, against which antibiotics have no effect.
Key information
- If your child is wheezing or struggling to breathe, call NHS 111 for advice or 999 in an emergency
- Do not request or administer antibiotics without a GP or clinician confirming they are appropriate
- NHS 111 is available 24 hours a day, seven days a week by phone or online
