"I thought I had a UTI. I felt the urgency to urinate. I remember having one tablet of Phenazopyridine Hcl 100 mg Tab Ecip left , so I took it. In about 1/2 hour I felt my stomach swell bad and then got this horrendous back pain in my lower left back side. I took these before and didn't remember this reaction.  I thought I might ride it out until I could get to the Urgent Clinic the next day. The pain became so intense, that I couldn't lay, sit or stand. I realized something was wrong with me and I needed help. I phoned the local police department. While I had the dispatcher on the phone, I began to vomit profusely. Turned out I had a kidney stone. Did this medicine cause these reactions, or was this a coincidence. I wouldn't take again."
