We always go to the vets too, even though we sometimes have a supply of meds at home. I just think that the vet is better equipped at dealing with the issue ( I know not all of them are, but ours are rabbit savvy, so it's not worth taking the risk!).
We usually get given metacam, baytril, metacloprimide. Sometimes we are told to syringe feed, but we are almost always sent home with the bun, as our vets believes that there is a better chance of recovery in familiar surroundings. The bun is usually only admitted if they haven't improved overnight ( or in the unlikely event that they are in a really bad way when we take them in).
Copious amounts of smelly herbs, apple sticks, greens, pellets, hay usually do the trick, although hay and pellets don't usually get touched until a few days later. They all seem to prefer basil, mint and parsley when they're ill.
Encourage them to move about and keep them next to bonded partners ( but not with them, as you need to monitor output, as others have said).
