Vial supply planner
See how many doses one vial gives, how long it lasts on your schedule, the date it runs out, and how many vials a full run needs.
Vial by vial
How it works
Doses per vial is the vial's total amount divided by your dose, rounded down. The schedule sets how fast you use them.
Mixed vials only keep for a limited time. If a vial would outlast its use-by window, it has to be finished early, and you need more vials than the maths alone suggests. This planner accounts for that.
This tool does arithmetic on numbers you enter. It does not suggest or check doses. Your dose and how to mix it come from your healthcare professional.
