? Is it okay to store Lantus in airtight ziploc bag? Mine has particles in it....

[katiesmom]

I have a vial of Lantus that is less than 3 weeks old. It has been refrigerated of course, I have a temperature gauge in the fridge sitting right next to the Lantus so I know it doesnt get too cold. I am extremely careful, never shoot insulin back into the vial, I dont even shoot air in the vial. it's not left out any longer than than it takes to do a up an injection.

This vial definitely has particles floating around in it. I noticed it a week ago, and I thought they were little air bubbles, but after looking closer with a flashlight I am sure they are particles.

How would this happen? The only other thing I do, which I dont know if its a good idea, I store the insulin in it's original box, in a airtight "ziploc" type baggy. Is that ok? Maybe it needs to "breathe"? I notice condensation on the bottle after it's out on the counter for a few minutes, so moisture build up degrading the insulin or the stopper? I dont know... I stored it like that because thought it would keep out any bacteria circulating about in the air.
Thoughts?

Putting the vial in an airtight ziplock bag will not have any effect

Even according to the manufacturer, Lantus is supposed to be good for 28 days when left at room temperature once open. I would talk to whoever you got the insulin from and try to get them to give a replacement. Although the manufacturer does not say so , Lantus stored in the fridge should be able to last 3-6 months once open. Once there are particles in the vial there is nothing you can do to stop the degragation
