Macrobid, or nitrofurantoin, is very good for UTI treatment and the methods it does so makes bacteria unlikely to build resistance to it. Macrobid should be the first option before general antibiotics for this reason.

Macrobid works very well and usually is taken twice daily (breakfast, dinner). For me, I had fatigue and headaches but they left after two days. After that, I felt fine for the remaining 8 days. And it worked!"
