Rockey - to the best of my knowledge, all of the antibiotics in question are by prescription only. You're looking for something with Polymyxin B sulfate combined with another broad spectrum antibiotic. I can't recall off the top of my head what is and is not toxic to frogs but I have a feeling that either Bacitracin or Neomycin is toxic to amphibians and that is what is commonly available in general animal eye ointment.
