• staph:
  • doxy
  • linezolid
  • clinda (diarrhea, often high levels of resistance)

  • keflex (true q6h dosing)
  • cefadroxil (BID)
  • amoxicillin
  • augmentin (“amoxicillin plus diarrhea”)

Don’t treat UA w/o sx, unless pregnant or prior to urologic procedure. Symptomatic sterile pyuria: can challenge with abx or wait and watch.

• nitrofurantoin
• bactrim
• augmentin
• cefdinir (3rd gen)
• fosfomycin (one time dose, covers ESBL, expensive)
• don’t need a fluoroquinolone unless pyelo o/p tx (e.g. young female who is doing ok w PO intake)

• strep pneumo, H flu, moraxella, legionella, mycoplasma, staph, PsA

• azithromycin + something
  • amox
  • augmentin
• FQ

• CAP: azithromycin + CTX
• HAP: vanc + cefe, vanc + zosyn
• think about MRSA nares, though can have nares -ve/trachea +ve

• n meningitidis, strep pneumo (MCC), H flu, listeria (>50yo, immunocompromised)
• HSV

• vanc (s pneumo is sometimes resistant to CTX, not for MRSA)
• CTX
