My understanding is that when you use antibiotics for sick fish in a freshwater tank, you pretty much kill all the bacteria, both good and bad, in the tank and the biofilter. Does this mean that the tank now has to go thru another 4-6 week period to cycle as was the case when the tank was new?
Tank cycling duration after using antibiotics

Many antibiotics (along with other meds) will kill the bio filter requiring another 4-6 week "cycling" process. If you have not yet treated the tank you might consider Maracyn and Maracyn II. They are formulated so that the nitrifying bacteria is not killed.

Also, FuranII says it will not harm the good bacteria.
However, when I medicate a sick fish I'll move him to a hospital tank to avoid this kind of problem. I have a small filter I use only for this tank and I use new filter floss each time I set it up. Since the fish will not stay long in that tank, and constant water changes are used when using antibiotics, there won't be any need for biological filtration in the hospital tank.

I used erythromycin EM tablets from Aquarium Products (which someone told me today is not very good stuff).
If I have killed off the good bacteria in my tank and biofilter, I am quite pissed since I just got my tank cycled a few weeks ago (it took 10.5 weeks to cycle this tank!!!) at the expense of a few of my fish. The idea of buying more "sacrificial lambs" in order to cycle the tank once is quite frustrating and frankly sucks!
