Answer

Successful treatment of bacteriuria prevents pyelonephritis. Fluoroquinolones and aminoglycosides should be avoided in pregnancy. Accepted regimens for treating asymptomatic bacteriuria include the following:

  • Amoxicillin 250 mg orally 3 times a day for 3 or 7 days; or 3 g in a single dose
  • Cephalexin 2 or 3 g in a single dose
  • Nitrofurantoin 200 mg in a single dose; or 100 mg 4 times a day for 3 or 7 days
