What do I do with the unopened ball?

I continue with my "honeymoon" puncturing the 4 units of NPH when I went to bed and using the humalog only in the event that after eating I was more than 160. The fact is that I have had a ball without opening outside theRefrigerator waiting at the time of having to use it for a month and I have not needed (my educator told me that it was what I could keep it once open).Now I doubt between throwing it or not.What do you advise me?

If you have used it, it should only be maintained for 1 month.
So discard it.

But you have used anything, not once, you can keep it up to the expiration date that puts you.

I have not used it, but I had it out of the fridge just in case I needed it.

You can use it without problem then.
Since the Boli "opens" (for the first time the needle is put) there are 30 days to use it.
After that time you have to discard it, according to manufacturers.

Thank you
