When I finally read it, I started drinking lots of water, but by that time, I had started having
bladder infection symptoms, burning, urgency, frequency. Strange, since Bactrim is used for Bladder infections. I asked the doctor today if the fact that I didn't drink enough for the first week on Bactrim could have contributed to the bladder symptoms I'm having, and he said possibly. He told me to keep taking the Bactrim, and prescribed Urogesic Blue.
