About This Calculator
Ibuprofen (sold as Advil, Motrin, and generic brands) is a nonsteroidal anti-inflammatory drug (NSAID) used for pain, fever, and inflammation. Proper weight-based dosing ensures both safety and effectiveness. This calculator uses the standard 5-10 mg/kg dosing guideline.
How It Works
Enter the patient's weight and select the dosing intensity (5-10 mg/kg). The calculator computes the appropriate dose in milligrams and converts it to the volume of liquid medication. For safety, single doses are capped at 800mg and daily doses at 3200mg (or 40mg/kg/day for children).
