Routes

• Antibiotics for Pseudomonas UTI may be given intravenously (IV) or orally.
  
  

Types

• Pseudomonas UTIs are typically treated with monotherapy, or a single antibiotic. If the organism spreads to your bloodstream (bacteremia) or involves your kidneys, you may need multi-drug therapy.
  
  

Identification

• IV aminoglycoside drugs such as tobramycin and gentamycin are effective forms of monotherapy for Pseudomonas UTI. Multi-drug therapy may involve aminoglycosides plus another antibiotic such as penicillin, cephalosporins like cefoxitin, or carbepenems including imipenem. Ciprofloxacin is the preferred oral drug for this infection.
  
  

Time Frame

• If your UTI is confined to your bladder, you'll need 3 to 5 days of antibiotics. Complicated infections, especially in people with indwelling urinary catheters, can take 7 to 10 days to clear up. If your kidney is involved, you may need 2 to 3 weeks of antibiotics.
  
  

Considerations

• Your doctor will order a urine culture to determine the type of organism, and a drug sensitivity test to identify appropriate antibiotics to treat your UTI.
