I just noticed last night that our back up Lantus is expired. In 3 years we've only needed it once (her PDM got lost/stolen) and then she was out of town and didn't have it with her. Plus I didn't' realize then that the basal would still work so we really didn't need it. Luckily that time she was with another T1 and just borrowed some till the new PDM came. So I'm kind of thinking I don't really need to keep a back up. I can always call into a 24/hr pharmacy if I did. If she were going out of the country I definitely would but she's not. Thoughts? It just seems like kind of a waste.
