This is significant because treating UTIs effectively during pregnancy is crucial for both maternal and fetal health, and fosfomycin provides a convenient single-dose regimen. This can enhance adherence to treatment since it eliminates the need for multiple doses over several days, which can be particularly beneficial for pregnant women who may experience complications or challenges in managing their medication schedules.

Moreover, fosfomycin is considered safe to use during pregnancy, as it has a low fetal risk profile. It operates through a unique mechanism that disrupts bacterial cell wall synthesis, and its effectiveness against common UTI pathogens makes it a preferred choice in this population.

Bactrim is contraindicated, especially in the first trimester and near delivery, due to its potential effects on the fetus.
