About
Pediatric dosing is not simply a fraction of an adult dose; it requires calculation based on milligrams per kilogram (mg/kg) of body weight. This tool helps clinicians and parents determine the safe volume of medication for children. It incorporates a database of common pediatric formulations (e.g., Amoxicillin, Ibuprofen, Acetaminophen) and triggers safety alerts if the calculated dose exceeds the recommended daily maximum or safe therapeutic window.
