I planned worming my horses tomorrow. I bought 2 today as had one at home. I've just discovered the 1 at home expired 08/2014. Should I use it or bin it?

It'll be fine. I have a friend who is a medical rep for vet products. He gave me a big box of out of date wormers a while ago. He said they are effective for ages after the use by date.

I would not use it.

It is not that I think it will damage your horse, but if it is less effective it may help with worm resistance.

If it were up to 3 months over I may use it, but not that far out of date.
