>Then we bring in the big guns, things like Vancomycin Vancomycin used to be a big gun, but not really any longer. Source: https://en.wikipedia.org/wiki/Vancomycin https://en.wikipedia.org/wiki/Vancomycin From the article: For many years since its initial use, vancomycin has traditionally been reserved as a drug of "last resort"... Recently, however, vancomycin resistant organisms are becoming common. Thus, vancomycin is increasingly being displaced from this role by newer antibiotics >So governments limit Vancomycin use so as to not give bacteria the opportunity to evolve and develop resistance. Vancomycin actually has a high hurdle to use naturally. It possesses poor oral bioavailability; it must be given intravenously for most infections. It can't be abused as easily by doctors prescribing it for things like colds because you have to be hooked up to an IV to get it. Having said that, it is still a very old antibiotic (from 1953) and resistance has built up from its use. A few months ago I had Vancomycin + Ciprofloxacin administered intravenously for four days due to an infection following a severe puncture wound to my foot. It's still prescribed but it's not "the big guns" it used to be.
