I agree, if you think you have a serious infection, go to a doc. However, vet antibiotics ARE the same as Human antibiotics, made by the same companies, different labels. There was this big expose' on national network tv about a year ago questioning why the same drugs cost 1/4 as much for your pets. I do a lot of backpacking and traveling so I always have a supply of antibiotics on have including those commonly used for infections.
