When the dose changes mid-vial

Dose changes rarely line up neatly with vial boundaries. You step up on a Tuesday and the vial you are drawing from is two thirds gone, which creates a small bookkeeping problem that is easy to get wrong.

The concentration has not changed. That is the important thing to hold on to. What changes is the volume you draw, and therefore how many doses remain in the vial, which is now a different and smaller number than the one you calculated when you mixed it.

So the run-out projection needs redoing at the moment of the dose change, not at the next refill. This is the single most common reason people are caught short: the projection was correct when made and silently stopped being correct the day the dose went up.

In the log itself, the thing to avoid is editing history. The doses before the change were what they were. Add a new row with the new dose from the date it started, and leave the earlier rows alone. A log that has been tidied up retroactively cannot answer questions about timing.

It also helps to note the reason for the change alongside it, in three or four words. Planned titration, tolerability, clinician advice. Six months later the sequence of doses is still legible but the reasoning behind each step is not, unless it was written down.

Having the vial, the doses drawn from it and the remaining count in one Peptide Tracker & Calculator means the recalculation is automatic rather than something you have to remember to do at the worst possible moment.
