Note

  • Using a product with incorrect amoxicillin-clavulanate could result in sub-therapeutic clavulanate concentrations or severe diarrhea.

  • If possible, limit clavulanate to less than 6.4 -10 mg/kg/24h to reduce GI side effects.

  • Based upon usual dosing in pediatric patients less than 35 kg, use of the 7:1 ratio suspension provides 6.4-8.6 mg/kg/24h of clavulanate and 4:1 ratio suspension provides 11.2-15 mg/kg/24h of clavulanate.
