This is response is to expound on Noreen's post regarding ulcers. I agree you should always consult your vet before giving any medications, but a healthy horse can tolerate a minimum dose of bute for extended periods without any problems.
The key word is "pre-existing" ulcers. It's not a given that long term use of bute given in the proper amounts will "cause" ulcers or any of the other problems such as kidney failure. If you have a bleeder, or one with renal problems then bute may not be for them, but if there are no pre-existing problems it's a good long tem solution for some pain issues.
That said, foals are in the high risk category and bute should be used with extreme caution.
