I had a bout of diverticulitis was given ciprofloxacin and metronidazole ended up with cdiff?I'm allergic to penicillin. When given Ciprofloxacin and metronidazole for 2 days in the hospital and 10 days more at home, I ended up with cdiff. What can I take when I get sick with ear infection/sinius infection, etc, or if the diverticulitis returns? Could two 300 mg of clidamycin before a dental cleaning cause cdiff?
