genuine question about stability that I am slightly embarrassed to ask
Trying to get a straight answer on this: genuine question about stability that I am slightly embarrassed to ask. Kept a vial at room temperature for eleven days by accident. Tested it out of guilt. It was fine. Ordered from the warehouse in the Netherlands instead of origin and the transit went from a fortnight to 11…
Not convinced. A warm pack on day six is expected behaviour from a pack designed for four.
Yes — reconstitution date on the vial. It is the number you will want and cannot reconstruct.
Correction: that stability figure covers the lyophilised powder, not the reconstituted solution. Different claim entirely.
How many days in transit, and which month?
Put a logger in three consecutive orders. Two never went above the range at all and the third spent four hours warm on a Friday. Cost me almost nothing to stop wondering.
Lyophilisation removes the water that drives most degradation pathways. That is why the dry cake is comparatively robust and the reconstituted solution is not.

Disagreeing with this line only: freezing a reconstituted vial is not a safe default.
