urinary tract infection
"Was prescribed this for a UTI. Only took 2 pills, one in afternoon and one in the night before bed. Woke up the next morning and couldn't balance at all and had a strange headache right in the middle of my forehead.

Didn't take any more pills (thank goodness). It has been 4 days now and the side effects still are persisting.

Judging by the other people here, it won't be long before there is a class action lawsuit. I am beyond pissed and wish I would have read this before. Will never make the same mistake again. I have taken antibiotics before for UTIs and have never had any problems, so I didn't think twice this time."
