expired lantus

[christie]

i thought that i had read somewhere that after a certain time after being opened lantus is not good anymore. can someone let me know if that is the case and how long an opened vial lasts,thanks

Christie,

According to the manufacturers, performance of Lantus starts detriorating 28 days after the seal on a vial has been broken. Some people find that this happens sooner - at about 23 days. I found that my control was OK for about 6 weeks. During week seven after opening the vial, my blood sugars went all over the place. I started a new vial and they settled down again.

Cheers,

Mark

After it's been open/used for about 30 days my sugars start going screwy. My endo said 28 days.

[christie]

so then do you just keep track of the 28 days and then toss it?i thought i had heard of it not working after awhile ,when mine started going high for no reason i thought mine was expired,it was over 5 weeks opened.

I keep my insulin vials in their boxes. I just make a note on the box what date I opened it and so I know when it's time to open a fresh vial.

same with me, I write the day the vial was opened on the box, but I start watching morning B/G readings at 28 days and when readings go up, bottle goes in trash

I used to do that, but then I got lazy, and now I just replace the vial each month.
