What is the maximum daily dose of acetaminophen for a child weighing 15 kg?

To determine the maximum daily dose of acetaminophen for a child, guidelines generally recommend a dosage of 10 to 15 mg/kg per dose, given every 4 to 6 hours as needed. For a child weighing 15 kg, the calculation for the maximum daily dose can be approached as follows:

• Using the higher end of the dosage range (15 mg/kg) for a 15 kg child:

• 15 kg × 15 mg/kg = 225 mg per dose.

Since this can be given every 4 to 6 hours, a maximum of 4 doses can be administered in a 24-hour period. Therefore, the total maximum daily dose would be:

• 225 mg/dose × 4 doses = 900 mg.

Utilizing the lower end of the dosing (10 mg/kg) gives:

• 15 kg × 10 mg/kg = 150 mg per dose.

• 150 mg/dose × 4 doses = 600 mg total daily.

Hence, the reasonable maximum daily dose falls into the range of 600 mg to 900 mg.

In cases where an emergency setting or specific guidelines apply, the accepted recommendation for treatment may allow up to 75 mg/kg daily
