Pediatric Dosage Calculations: Amoxicillin

Always confirm the dosage with a doctor or pharmacist before administering amoxicillin to a child. Standard pediatric dosages are typically calculated based on the child’s weight in kilograms (kg). A common dosage is 20-40 mg/kg/day, divided into two or three doses.

Example Calculation

Let’s say a child weighs 20 kg. Using the lower end of the dosage range (20 mg/kg/day), the total daily dose would be 20 mg/kg * 20 kg = 400 mg. If this is administered in two doses, each dose would be 200 mg. If given three times daily, each dose is approximately 133 mg. Always round to the nearest available dosage form.

Amoxicillin is available in various strengths, such as 125 mg/5 mL, 250 mg/5 mL, and others. To determine the appropriate volume to administer, use this formula: (Desired dose in mg) / (Concentration in mg/mL) = Volume in mL.

Liquid Dosage Forms

Accurate measurement is crucial when using liquid amoxicillin. Use a measuring spoon or syringe designed for medicine, not a kitchen spoon. Follow the instructions on the medication label carefully, paying close attention to the concentration.

Remember, these are examples; individual dosage may vary depending on factors such as the child’s age, medical condition, and the specific infection being treated. Always consult the prescribing information and a healthcare professional for guidance.
