I have been a diabetic for 55 years, and was never concerned about using insulin for just 28 days. I use it longer, and check the bottle to make sure it is OK. Does anyone else do this? Also, found out that Lantus losses about 1% potency each month. If you can't keep it in the refrigerator for over a month…how come the 2010 experation date? I think this is all just to sell more insulin!

My doctor told me if insulin is kept in the fridge, it should last up to 3 months. If I take it out often, then it should be used within 30 days.

If the insulin is kept could and sealed it is supposedly good until the expiration date only after it out of the refrig and warm than the 28 days come into play

I take Novalin 70/30 and Novalog. I keep them in the refrigerator and have never had a problem with them. I sometimes keep them for a couple of months before I use them. I hadn't been aware that it was a problem. Thanks for making that info available.

This doesn't really apply to insulin that's kept in the refrigerator. It's when you take it out and start to use it, like pens or people who leave vials in use out.

It depends on the type. For instance Lantus is known for pretty much turning to water after 28 days, others can go as long as 42. Best to check how quickly the type(s) you use break down.
