Although it is standard procedure for some people to give anitbiotics, I think it is a bad one. I definitely think it is bad to use it. That said, it's up to you. Lots of people do use it and lots of people think it's more harmful than good. Do a search on the site about antibiotics and you will find endless discussions on the topic. In general, antibiotics are over-prescribed for humans, and are present in far too much of our food supply. To me, giving antibiotics "just in case" is like taking your only bandaid and sticking it on your arm "just in case" you get a cut. Now, when you actually do get a cut, and it is on your leg, you have to reuse your only bandaid by peeling it off your arm and sticking it on your leg. Only now the adhesive doesn't work so well because it's been peeled off your arm. That bandaid did nothing on your arm and now it's less useful on your truly cut leg. That is the same thing as with antibiotics. Give it to people or animals when they don't need it and we build up our own and the bacteria's resistance to them and when we really need them, they don't work.
