Hi, I came down with a UTI on xmas day.  It was 4 days later before I got to the drs and was prescribed antibiotics (keflex).  after taking it for 3 full days i got sick - diarrhea, nausia, and generally feeling very sick.  I stopped taking the anitibiotics but now I am getting lower grade pain in the lower abdomen, obviously I still have the UTI but wont be able to get back to see a dr for another 3 days.  should I start taking the antibiotics again?
Hello welcome to ChatDoctoryes the diarrhea, nausea are indeed the side effects of antibiotics you were prescribed, but the fact is that your UTI Won't GET RESOLVED WITHOUT TAKING APPROPRIATE COURSE OF ANTIBIOTICS FOR A SPECIFIC PERIOD...but there is another fact that it's not the correct method to take antibiotics blindly on hit and trial basis...the correct approach is to first get a test named URINE CULTURE AND SENSITIVITY which tells that to which specific antibiotics the bacteria causing infection is sensitive to...so get this test done and then start the most appropriate antibiotic to which your bacteria in the urine is most sensitive to and to prevent side effects of antibiotics ask your treating doctor to prescribe a ANTACID and PROBIOTIC so that you can prevent the undesired side effectsregardsChatDoctor
