About DosePlan

DosePlan was created to make a calculation many people do by hand simpler and safer: how many units to draw into an insulin syringe to reach the prescribed dose in mg.

What makes it different

• Step by step: one question at a time, with help finding the concentration on the label.
• No clutter: you type the dose instead of picking from a grid of buttons.
• Complete summary: several doses and several medications in one summary.
• Made for patients: a clean printout and a read-only share link.
• Private: calculations stay on your device.

The math

Concentration (mg/mL) = mg in the vial ÷ mL of diluent. Volume (mL) = dose ÷ concentration. Units = volume × 100 on a U-100 syringe.
