bladder infection
"I have taken this medication tons of times and every time without side effects. It is the only thing I can take to take care of my UTIs.
I took it off and on in the past for UTIs due to having 4 urether instead of two. Then I had to take it for 9 months while I was pregnant (one a day for prevention), never had a problem. 
Now years later, Just had a hysterectomy and had a UTI again. Asked for macrobid and within two days the pain is gone and I am getting better. Couldn't live without this medicine. I don't know what these people are talking about."
