Note: These are general examples only. Always follow prescriber's specific instructions.
Multiply the patient's weight in kilograms by the prescribed mg/kg dose. For example, a 70 kg patient receiving 10 mg/kg would need 700 mg.
Weight-based dosing ensures appropriate medication levels, especially critical for pediatric patients, where standard adult doses would be dangerous.
Divide pounds by 2.2 to get kilograms. For example, 154 lbs ÷ 2.2 = 70 kg. Use our kg to lbs converter for accurate conversions.
