urinary tract infection
"Given this for a UTI.  This is a horrible drug!    I only took 2 pills of this drug when I started getting the shakes and terrible anxiety.  Driving home from work, I was literally praying to god to get me home safely because I was shaking with a headache and awful anxiety.  Thankfully got home and had to sit down with my head between my legs because I thought I was going to pass out.  Spent an entire evening with anxiety and it persisted, to a lesser extent, the next day even off of the drug.  Also, did a number on my stomach - lost my appetite, probably due to the anxiety.  I think these side effects are common with this drug and very dangerous.  My pharmacist wasn't even sure if they still carried it.  Take with caution."
