Extreme caution on Excede!!
My twenty five year quarter horse was given 16cc of Excede six days ago and seemed fine until about the second day, started with loose stools and some swelling of his neck. I refused to give second dose after four days and soooo glad I did as of today the swelling in neck has now gotten so bad that both sides are huge and very hard all the way down to his chest area. The time release of the drug is the scariest part due to the length of time in the system so if a reaction happens it takes days to peak and up to eighteen days to clear out. I truly believe my horse would have died if I would have given the second dose. I have always been leary of new drugs and will always follow my gut instinct from now on. Hope this helps anyone else that might have to make the decision.
