Two weeks ago, I was diagnosed with diverticulitis. I took 500 mgs of Cipro and 1500 mgs of Flagyl for 8 1/2 days and had to stop because of side effects. I felt pretty good for several days but now diarrhea seems to be getting worse. Is this because my body is still fighting the infection or could the infection be getting worse?
Could be either one or both. It's never a good idea to stop taking antibiotics, and with diverticulitis, it's even a worse idea because of all the bacteria in the colon. You definitely need to call your doctor and tell him what's happening.
