So the upper dose would be 55lbs(1 kg/2.2lbs)(50mg/kg*day)(1day/4 doses)=312.5 mg/dose correct? So the available amount doesn't come into play when trying to determine the safe amount or does it?
I have absolute no clue how to work out this problem, and i need help in working out the steps. Order: erythromycin oral suspension 300 mg q 6h PO. The child weighs 55lbs. The safe dosage range is 30 mg/kg/day-50 mg/kg/day in 4 divided doses. Available: erythromycin oral suspension 200 mg/5mL. What is the safe dose range?
