Key Points

  • Preferred antibiotics for acute cystitis are nitrofurantoin, or trimethoprim-sulfamethoxazole (TMP-SMX) if local resistance rates are < 20%.
  • In patients suspected of pyelonephritis, a urine culture and susceptibility testing should always be performed.
  • Preferred antibiotics for outpatient pyelonephritis are a fluoroquinolone or TMP-SMX. Consider an initial single-dose IV ceftriaxone or an aminoglycoside if community resistance is > 10% or, for TMP-SMX, if susceptibility unknown.
  • Women with pyelonephritis requiring hospitalization should be initially treated with an IV antimicrobial regimen such as a fluoroquinolone, an aminoglycoside with or without ampicillin, an extended-spectrum cephalosporin or extended-spectrum penicillin with or without an aminoglycoside, or a carbapenem.
