Azithromycin oral dose is 12 mg/kg/day with a maximum of 500 mg; how often is it given?

Dividing the daily mg/kg dose into two equal portions is used to meet the weight-based target while staying within the maximum daily limit. Azithromycin’s long tissue half-life allows reliable exposure from divided doses, and giving two doses 12 hours apart keeps each administration below the 500 mg ceiling while still delivering the 12 mg/kg per day total. For example, a child who weighs 25 kg would have a 300 mg per day target, which can be given as 150 mg every 12 hours. In heavier children, splitting the daily amount helps ensure you don’t exceed the 500 mg per day cap while maintaining the prescribed daily total.
