The recommended dose of Amoksiklav ES for paediatric children weighing less than 40 kg is (90 + 6.4 mg)/kg body weight/day in two divided doses. For a child weighing 14 kg, it will be 1260 + 90 mg/day in two divided doses.

In the case of a dosage of 2 x 5.25 ml, the daily dose will be 1260 + 90 mg, which is exactly as recommended.

To sum up, the dose of Amoksiklav ES antibiotic selected by your doctor is correct.

In addition, I would like to remind you that too low a dose of an antibiotic may be ineffective and contribute to the development of bacterial resistance, while too high a dose may be harmful and cause side effects. I encourage you to read the following articles:
