bladder infection
"First off, I have a history of having UTI.  This past one has been a real doozy and the medication was changed four times!  The last antibiotic prescribed is macrobid 100 mg 2xday.  The first day I was nauseated and delirious with bad nightmares.  It was a sick flu like feeling along with bad chills.  I kept taking them as I thought what else.?!  This sick feeling calmed by third day and two more (4 pills) left.  I feel better but my bladder has been through too much with so many infections with wrong medications.  I really wish my Dr would focus more on prevention.
Macrobid definitely gave me bad side effects compared to any other antibiotics...but it seemed to clear the infection hopefully it doesn't return!"
