Pediatric dosage Dose per administration and volume to give, from a mg/kg/day prescription. IV drip rate Convert an infusion volume and time to mL/h and drops per minute. Alligation Mix a high- and low-concentration solution to hit a target strength, by the alligation rule.

Dispensing-bench calculations: weight-based dosing, IV infusion and drip rates, and the alligation method for mixing two concentrations to a target strength.

Every result shows the formula and the substitution used, so it can be checked against the prescription before it reaches the patient.

Frequently asked questions

Do these replace checking the prescription?

No. They compute the arithmetic correctly for the values entered, but never substitute for verifying the prescription, the patient’s weight and allergies, and your institution’s protocols. A second, independent check is standard practice for any dose calculation.
