Since so many older people get uti’s I want to post an experience I had with Nitrofurantoin as an example of how some meds work for some people but not others.
After two pills I felt like someone had hit me all over my body with a ball bat and left me in a parking lot. My husband had to read med bottle labels since I knew there were words but they made no sense. Plus other symptoms I don't remember.
I called my regular doc’s fill-in who prescribed cipro which also has an extremely long list of side effects but has worked for me in the past.
My point is that obviously uti’s can be really bad and that meds can certainly help but we have to be aware and ready for side effects that perhaps your loved ones can't tell you about.
I was fortunate ... I can still verbalize.
