I am confused because you say inject orally? Orally means in the mouth? Injections are done under the skin on the first(front) third of body. I have used baytril for years and have never had a reaction like mentioned in the post about the rectic. That vet probably didnt mix the baytril correctly, not sure but I have given many many shots and at worse have seen a minor bruise(and thats when I was a rookie).
I think you are fine give or take a few hours. Sounds like its more of a preventative measure. Best of luck![]()
