urinary tract infection
"Please don't be scared to take this medication.   I read the reviews and was horrified, but honestly the drug was very tolerable.  I went through 2 other medications for UTI before I was prescribed this one. First it was Bactrim, which a few hours after taking 3rd dose I got hives.  Second was Ciprofloxacin Hcl 500mg and I ended up with tendinitis in both legs.  Thirdly is Macrobid 100mg 2x a day for 7 days.  My advice is to take it with a full meal.  Only side effects I get is slight drowsiness, and nausea close to the 12 hours mark of my next dose.  Eat large meals before taking Macrobid and then snack throughout the day and drink lots of fluids.  You'll be ok."
