Bladder Infection
"I have a urinary tract infection and was prescribed this medication along with phenazo, which takes the burn out of urination. They warned me that Macrobid might cause slight stomach upset but I threw up four times in a row last night and feel nauseous all the time (regardless of how much I eat).

I had a UTI a few years ago and was prescribed a pill that caused no stomach upset. Why are they prescribing macrobid now?"
