Hi I take care of my 88 yr old mother who had a UTI , they gave her cipro, but had to take her back to the er, the next dr said cipro wouldn't work so he pesrcribed Bactrim , which she had a bad reaction to not sleeping , confused, shaking, sorry she has Dementia, I stoped giving the Bactrim but im afraid she still has the UTI, is there another drug she can use
