Good evening Dr. I require your kind advice regarding my mom's medication. You see my mom had persistent uti & e-coli infection for almost a year throughout 2018-2019. Her health deteriorated due to which she had a fall last year & got fractures in her spine & right shoulder, for which she was operated with screws & rod insertions i.e. Dorsal spine fixation & proximal humerus plating. However she had incidents of granulation tissue pouring out on the spine suture area twice after the initial surgery, due to which she had been operated two more times to sort out the problem. The reason for the granulation tissue pouring out was described as the Dr. As being due to high uti & e-coli infection. She took iv antibiotics for 7 weeks and was also prescribed nitrofurantoin 100 mg for 1 year which would completely eliminate her uti & e-coli. My mom however had for only 5 months & quit. It's been 4 months now since she quit, & now suddenly she's experiencing frequent urination, overactive bladder and urine incontinence since 3 days. Also there is inflammation during urination. Kindly suggest me if there is no harm if she starts nitrofurantoin 100 again and so for how long i.e. Remaining 7 months or any other period?
