expired

Hello , i havent been back here in a lot of years, i assume i know the answer to this question, I have an unopened vial of bam, vials 1,2,3, expired 2106 whats the opinion on using it? Not life or death but have a buck with about 15 feet of fence in his rack...hes not happy.

Can anyone tell me if there is any medications that are ok to use past the exp date? Penicillin, Dex, drax, etc..?

First we picked up two bred does from a farm a couple hours away, then we picked up a fawn and bred doe from another farm close by. They were all darted with BAM, put in the trailer and we woke them back up. Went out this morning and fawn doe was laying in the barn, couldn't get up, breathing...
