Expired insulin - To use or not

8 posts in this topic

I have a vial of Humalog, new and unopened, that has an expiration date of 12/07. Am I risking by using this insulin?

I wouldn’t personally use it, but that is just because I don’t want to risk a huge bg spike from lack of insulin after a meal, its not worth the risk.

I would use it and test. I might not use it in a pump (infusion set, etc) without first trying one shot to confirm viability. The stuff doesn't go from 100% perfect to useless in 3 months. It loses potency over time. The only caveat is cloudiness. It has to be clear.

Do you have an vials of humalog that are NOT expired?

 

If so, it is unnecessary to use the expired one. The viability of expired insulin is QUESTIONABLE at best.

 

I **ALWAYS** feel like I did something wrong when I have BG spikes that I am directly responsible for and feel like I should be sitting in the naughty chair for having done so..;)

 

Hey, if you have NO other choice, you do what you've got to do, but if you have insulin within it's shelf life range, stick with the "good stuff". While sticking a proverbial fly in the ointment is entertaining, guinea pigs are just that because they can't say NO.

 

And just an FYI, I am GREAT at giving advice *cough* at times lousy at taking it. :( YMMV

If the insulin has been kept in the fridge the entire time and it is within 2 or 3 months of the expiration date, I'd have no reservations about using it. Of course, I'd try to use it within 30 days of opening it, and, in this case, try to keep it cool (fridged as much as possible) unit used up. This is based on past experience. Like ALL products, the expiration date is set earlier than necessary I suppose to allow for persons who have let it overheat or not handled it properly. Of course, I have to admit that I also take various pills that are a year past expiration date (also, still effective and no harm). Just MY Opinion, and as you've seen, lots of others have very different opinions about this.

I'd use Humulin and Humalog for 8-10 weeks after opening. I'd discard once the insulin became wonky enough that I couldn't maintain satisfactory control. The last go-round, I think perhaps I should have stopped at six weeks.

 

In that sense, I frequently use expired insulin. As for past-the-expiration-date... I've never tried.
