Some of the antibiotics my wife gives to her patients have gone from $14 to $1400.It's not about not making the meds. It's about the FDA making the meds RX only to reduce antibiotic overuse. From my understanding this applies right now mainly to meds added to feed- and that they may be expanding it to meds added to water. Some meds are no longer allowed in combination but singally they are OK. Tylan, Penicillin, Oxytetracycline, and Tetracycline are on this list. Corid/Sulmet and Denagard are not. For now this does not affect injectable versions. I'm unsure on whether it affects powdered versions yet but I'm guessing it does. This is going to be a tough change for those of us used to treating our birds ourselves without a vet visit.
