Dexamethasone

Dex is a cortisteroid. It will reduce inflamation and counteract allergic reactions. Like any cortisone or steroid, it's not good to over do it. I would only use it for injury and poison bites. That way there is little chance of side effects. I used it on race horses pre race 24 hours out for several years with no ill effects but that was usually only once a month or so and only 5cc's for a big horse. If I had a dog come up sore after a hard hunt, I gave them an asprin a day for two or three days and it worked good.
I had to take dex during chemo to help counter the effects of the chemo drugs. Nowhere could I find that it would affect your kidneys. I know if you take alot of it, you have to tapper off of it slowly or it can cause side effects from withdrawle.
