Does Macrobid Treat All Types of Utis?
Medically reviewed by Linda Girgis | MD, Girgis Family Medicine on August 20th, 2026.
Macrobid does not treat all types of UTIs effectively. This antibiotic specifically targets uncomplicated lower urinary tract infections, primarily bladder infections (cystitis) in women. Studies show Macrobid achieves cure rates of 85-95% for uncomplicated cystitis caused by E. coli and other susceptible bacteria. However, it's not recommended for kidney infections (pyelonephritis), complicated UTIs, or infections in men due to poor tissue penetration in the upper urinary tract and prostate. The medication also shows limited effectiveness against certain resistant bacterial strains like Pseudomonas and some Enterobacter species. Your healthcare provider will determine if Macrobid is appropriate based on your specific infection type, location, and bacterial culture results.
