Tablet dosage

Dose ordered / amount on hand X quantity = amount needed

Injectable dosage

Dose ordered / amount on hand X mL = amount needed

Weight Based Dosages

dose ordered / amount on hand X kg = amount needed

IV flow rate (gtt/min)

mL of solution / time (minutes) X drop factor = gtt/min

IV Flow rate (mL/hr)

Dose ordered / amount on hand X mL

IV flow rate (weight based)

Dose ordered x kg x time (min) x mL / amount on hand

IV flow rate (mcg/min)

dose ordered X 60 X mL / amount on hand
