I just saw in a post that this person had to inject Dex unexpectedly. First, I don't even know what Dex is?! And it sounds like I should have it here in case I need it. But I don't know when to give it!? UGH. It was mentioned along with EPI so I'm assuming it is for an allergic reaction...
So, what is it, how do I get it and when do I use it?
I don't even think it's on the vet kit list.

You are correct, Dex (dexamethasone) is not on a typical vet kit list. It is a corticosteroid and is used to treat allergic reactions. There is some concern that steroid use can trigger a bout of laminitis though it's used fairly often in horses and studies haven't shown that laminitis can be a side effect.

Thanks for the info!

Sounds like if a horse tries any new medication, it would be good to have around. And if only used in an emergency situation, risk of laminitis would be the least of your worries.
Great information. Thanks so much.

You can only get it from a vet as far as I know and not to be used lightly. If/when you must give your horse vaccines or antibiotics via a hypodermic needle you should always check with your vet concerning what you may need to have on hand to counteract bad reactions. Simple allergic reactions like hives are best dealt with using something like Benedryl. Again, consult with your vet.
