Look on the top of the box for the expiration date. Don't use beyond that date unless you show with control solution they are still in range.

Expiery date? If you mean how long do they last, mine last 6 days. The expiration date is the time manufacturer says they are safe to use them.

I don't see expiration date, but I do see the packaging has copyright ©2012. I can tell you when it runs out if you want.

I think the expiration date is the one in the package but you don't know it until you buy the product, if that is what you are asking.

Check the back label. In the lower right hand corner there is an EXPIRATION DATE. Generally the potency is good for thirty days after the expiration date.

I don't think it is the expiration date. I am not sure that the stuff in this decays and the dates have the wrong format in anybodies date notation.

I believe it's the date of manufacture. I don't see how such an item could have a product expiration date. Hope this is helpful.

That is expiration date. You will get the best result by using the product before that date.

I'm not sure that I have ever seen an expiration date on mine. Have you purchased it yet? If so, look on the package. If not, I wouldn't worry about it expiring. It is sealed really well.

Expiration date is about a year. You just have to make sure that you refrigerate after opening.
