Calculating Amoxicillin Dosage for Children: A Step-by-Step Guide

Always consult your pediatrician before administering any medication to your child. Amoxicillin dosage is weight-based. First, determine your child’s weight in kilograms (kg). If you only know their weight in pounds (lbs), convert it using the formula: kg = lbs / 2.2.

Standard Dosage

The typical amoxicillin dosage for children is 20-40 mg/kg/day, divided into two doses (every 12 hours). For example, a 20 kg child might receive 400 mg total per day (20 mg/kg x 20 kg = 400 mg), split into 200mg doses twice daily. The doctor might prescribe a different dosage based on the infection’s severity.

Calculating the Dosage

Example: A child weighs 15 kg. The prescribed dosage is 30 mg/kg/day.

1. Calculate the total daily dose: 30 mg/kg x 15 kg = 450 mg/day.

2. Divide the daily dose by the number of doses per day: 450 mg/day / 2 doses = 225 mg per dose.

3. Administer 225 mg every 12 hours.

Available Forms and Considerations

Amoxicillin comes in various forms, including liquid suspensions and chewable tablets. Follow the instructions carefully. Measure liquid medications using a calibrated oral syringe or medicine cup to ensure accuracy. Note that suspension concentrations vary; the instructions on the label specify the amount to use to get the correct dose.

Monitoring and Safety

Closely monitor your child for any allergic reactions (rash, swelling, difficulty breathing) and report them immediately to the doctor. If you notice any side effects, contact your pediatrician. Store amoxicillin appropriately as directed on the label.
