bladder infection
"I have had years of urinary tract infections and trouble getting rid of them.  After cultures showed that the sulfa and penicillin drugs are not effective at all, Macrobid is the only one I take and sometimes it doesn't stop the infection on the first "round". Catching the infection early is important.  For some of the comments I just read, I suggest that you suggest to your Doctor, that you want a culture taken to see which drugs actually work on your particular bacteria.  I am on a new "regimen" now where I will finish up a full round of Macrobid and then take something else for a few months for prevention. Taking this drug for too long can cause lung problems."
