Which antibiotic is preferred for treating a lower urinary tract infection during pregnancy?

• A. Cefpodoxime
• B. Ciprofloxacin
• C. Trimethoprim-sulfamethoxazole
• D. Nitrofurantoin

Answer: (A)

Treating a lower urinary tract infection in pregnancy hinges on choosing an antibiotic with a strong safety profile for the fetus while still being effective against common urinary pathogens. Cefpodoxime fits this goal because it’s a cephalosporin with good fetal safety data and reliable activity against typical UTI organisms, making it a safer, well-tolerated option during pregnancy. Ciprofloxacin, a fluoroquinolone, is avoided in pregnancy due to potential effects on fetal cartilage development, so it’s not preferred. Trimethoprim-sulfamethoxazole is generally avoided, especially in the first trimester and late pregnancy, because of risks to the fetus from folate interruption and potential neonatal jaundice or kernicterus. Nitrofurantoin can be problematic late in pregnancy due to a risk of neonatal hemolysis, and its safety profile is less favorable for a pregnant patient with a UTI compared with cephalosporins. So, the best choice is the antibiotic that combines effectiveness with the strongest safety data for both mother and developing fetus in this scenario.
