A member asked:

How long for nitrofurantoin uti antibiotics to kick in?

A doctor has provided 1 answer

UTI: The action of this antimicrobial is very rapid, but the symptoms, which are a result of inflammation due to the infection, may persist for a day or two. If they persist for a longer time period see your doctor about a possible need to change antibiotics.
