urinary tract infection
"I am 60 and taking nitrofurantin for the first time. My urinary tract infection was totally out of control. In two days I feel a lot better not 100% I FEEL VERY TIRED, A BIT CONFUSED like I am sleepy after getting 8 hours sleep. I am avoiding exercise today. I do have asthma so my breathing is more stressed from this. I had a headache and vision problems."
