Very sad indeed. Does anyone know whether the vet wrote the wrong amount of selenium or the pharmacy prepared it incorrectly? Either way, I would think the pharmacy should have caught it. I think selenium would have to be given in a ridiculously high amount to be that toxic that rapidly. If there is a vet or someone who knows more about selenium on this board, I'd like to hear your thoughts. My working horses are supplemented with selenium, as are many racehorses, for 2 reasons. I am in a low-selenium area, and the amount of selenium added to commercial horse feeds is at such a low dose as to be completely inadequate for a working horse. I have my horses tested at Michigan State every so often to make sure I'm on track with the selenium.
