Reconstituting a multi-strength kit without mixing yourself up posts 121–124

This is a continuation of a long topic, addressed by post number rather than by page. Start at post 1.

t.vasquez, post #73: Preservative effectiveness is tested against a defined microbial challenge under defined conditions. It is not a licence to treat an entered vial as sterile indefinitely, and no supplier claims otherwise. Go to post

Picking up post #118: that is the part I would want checked first.

Reconstituting a multi-strength kit is worth one more sentence than it usually gets, and the sentence is the one about how the number was arrived at.

i.boateng, post #101: Reconstituting the whole vial when you will use a quarter of it is a decision to store the rest in solution, which is the least stable state it will ever be in. Sometimes that is the right trade and it should be a decision. One more caveat and then I will stop qualifying: the sample selected itself. Go to post

This is the first time the answer has come with its own limits attached. Appreciated.

Reconstituting a multi-strength kit sits at the boundary between what this community can usefully discuss and what it cannot, and I think it falls on the discussable side, narrowly.

Coming back to post #120, because the follow-up matters more than the original answer.

Reconstituting a multi-strength kit: if a kit contains 5 mg, 10 mg, 15 mg vials and you are reconstituting all of them, writing the concentration on each vial in permanent marker as you go is the single most useful thing you can do to avoid dose errors later.

Adding the caveat now so it does not have to be extracted later.
