Which Antibiotics Treat a UTI (and Which Don't)
Compare the antibiotics commonly used for different UTI contexts and understand why drugs like flucloxacillin, penicillin V, and benzylpenicillin are not standard empirical choices.
Can Flucloxacillin Treat a UTI?
No — flucloxacillin is not used for a typical UTI because it targets Gram-positive bacteria, not the usual Gram-negative urinary pathogens.
Can Phenoxymethylpenicillin (Penicillin V) Treat a UTI?
No — penicillin V is not a recommended UTI treatment because it is a narrow-spectrum oral penicillin and does not reliably cover the usual urinary pathogens.
Can Benzylpenicillin (Penicillin G) Treat a UTI?
Usually no — benzylpenicillin is not standard therapy for a typical UTI, although a culture-confirmed Group B Streptococcus urinary infection is a specific exception.
