    RE: insulin

    Some people get more than 28 days out of a vial, but after 28 days it is not guaranteed to keep it's effectiveness. You may have to start taking more and testing more to keep your blood sugars stable. And thenchange again quickly when you open a new bottle.

    RE: insulin

    I concur with cora. My dad would never allow his insulin to go to waste. But, he would never use beyond a week or two beyond expiration.
    I know nothing about your situation...how much you use, how well controlled you maintain, how steady and disciplined you are to your diet plan...so, it's impossible to suggest any advice to you. Each case is terribly unique, thus, everyone must roll their own dice (or, not roll, at all).

    Here's a few links that might help:
    Insulin Basics

    "Can I Use My Insulin Past its Expiration Date?"
    ( https://insulinnation.com/treatment/medicine-drugs/insulin-past-expiration-date/)

    Hope this helps and, in keeping with community policy, please don't say, "thank you" or extend any form of common courtesy or human decency. If you did, you'd stand out like a sore thumb. Good luck.

    RE: insulin

    Just a thought, and I do not know the cost difference between a bottle and that which come in the pen form. For example I take Lantus, and it comes in pen form. It has a much longer life than 28 days. Which is one of the things I do like about it. Because with my health plan I have to get 90 days mailed to me at a time.

    RE: insulin


    It would be nice if there was a simple answer to this question but the truth is different organic based compounds degrade at different rates.

    For example, everyone wouldn't mind eating cheese kept in a fridge for more than a month. But, how do you feel about drinking month old milk (organic vs non-organic?).

    And, the article, above, shows that different insulins have different shelf lives, therefore, making this question even more difficult to answer since the poster doesn't specify which kind of insulin they're taking.

    There are two essential rules that must be observed when taking insulin:

    1. Going "high" (hyperglycemia) is not good but it's a helluva lot safer than going "low" (hypoglycemia). A comatose diabetic is not a good state to be in (and, that's what can happen when hypoglycemic).

    2. You need to test with great frequency so you can see for yourself if your body is responding to each injection in a normal and "relatively" predictable manner. In other words, just because a vial that is being used for the very first time does not rule out the possibility that it's contents has expired, already. It's possible. But, even "if" the likelihood of this happening is remote, the only way you're going to find this out is if you test. Insulin users must be disciplined and fastidious when using this stuff! You need to be aware of the "effectiveness' of every injection you make and, if the insulin you're using is not providing the anticipated results you "expect" to see, does it matter what the hell date is written on the bottle?
