Zithromax is an inferior antibiotic for use in a survival setting. I would suggest Tequin which is a once a day quinolone (antibiotic class) that is effective against urinary tract, upper respiratory infections. It does have an FDA approved indication for treatment of soft tissue infections. I have never used it for that purpose. <br>If your concern is skin and soft tissue (wound) infections, then an anti-staph drug like Keflex or Duricef would be superior. <br>There is no primary indication for using Zithromax except in the treatment of community acquired pneumonia.<br>I have added both drugs to my military survival vest as well as the kit I fly with in general aviation aircraft.<br><br>Jeffery S.
