urinary tract infection
"I know this is about nitrofurantoin but I wanted to talk about the other drug I took before. 
Last week I noticed I had a UTI so I called my GP for an appointment they tested a sample and said there was some sort of urine infection so they prescribed me Trimethoprim (which I had taken previously before, 3 day course) this time the drug did not work at all if anything it made me worse, this also included vomiting so I called the GP very early this morning and was seen within 2 hours. I told them my symptoms and what had happened so I sent off a sample and they prescribed me nitrofurantoin 50mg capsules for 7 days, I've taken 2 doeses today (I have 4 pills a day) and I can honestly say it has already started to work."
