The bute is basically the equine equivalent to Ibuprofen (Advil, Tylenol, etc.) for people. Bute can help your horse’s aches and pains, fevers, and sore muscles. But, Bute can also be detrimental if not administered properly.
Thankfully, Bute can only be obtained by a vet prescription. Because of this, vets will prescribe an exact dosage for your horse. There is no question as to what is an appropriate amount and what is not; your vet will define this for you and your horse.
