Amoxicillin and Co-Amoxiclav (High Dose Therapy) - Additional Information

Why does my child require high-dose Amoxicillin or Co-amoxiclav/ Amoxicillin-Clavulanate (Augmentin®)?

High-dose amoxicillin (i.e. 80 to 90mg/kg/day) is usually prescribed for the treatment of certain infections, such as the following:

  • Chest (pneumonia),
  • Ear (otitis media), and/or
  • Sinuses (sinusitis)

The most common bacteria that causes these infections is known as Streptococcus pneumoniae. However, over the years, the effectiveness of antibiotics (such as amoxicillin) against Streptococcus pneumoniae has been reduced, as the bacteria change or mutate (i.e. develop antibiotic resistance). This can potentially lead to treatment failures. 

Hence, it is now recommended that high-dose Amoxicillin (80 to 90 mg/kg/day) be used to overcome this antibiotic resistance, to allow a more effective treatment of these infections. As a result, the volume of antibiotics that your child has to take may sometimes be of a larger volume.
