After going through 4 Cdiff infections in 2018, I'm leery of taking any antibiotics. I too have had numerous UTI's throughout my life. I was fortunate last winter that I didn't get numerous sinus infections since the Clindamycin they gave me for the one is what caused my first out with Cdiff. One of my doctors asked me during my last UTI in 2018 if I was using a PH balanced soap. At the time I was not. I've since changed to Vagasil PH balanced soap and have not had a single UTI in over a year. Walmart also had an Equate brand that is the same as the Vagasil and less expensive.
