I say call the vet you took him too and ask her exactly what meds she gave him. explain your concerns and how your snake is reacting. He is your pet, your responsibility, thus you should be included in his treatment. Its like going to your family doctor for tests and then not knowing what the test results are. If the vet doesn't want to disclose the information then perhaps you should find a different vet. I know its not easy finding vets that specialize in herps, but being included in the treatment is at the top on my list.
