Hi everyone, my cat has diabetes and uses 4 units of Lantus insulin per day. I don’t even get through a single pen (300 units) before it is technically expired. Pharmacies won’t sell me a single pen because they do not want to break the box. Does it make sense for me to buy a box of 5 pens? Are all the pens considered contaminated once the box is opened, as in do they all expire 28 days after the box is opened? Or can I use one pen at a time, and discard each pen after 1 month of use?
I would really appreciate any help with this question. I hope this isn’t something that has already been answered. I did search through the sub and couldn’t find anything that answers this.
