Flagyl
"The first time I ever had diverticulitis I ended up in the hospital for three days with massive doses of flagyl through an IV. After that I had a couple of bouts of what I thought were UTI's but ended up the start of diverticulitis (which mostly happens when I travel). Because I recognize the symptoms, I am allowed to have a few pills with me at all times just in case and catching the attack soon enough usually only requires a couple of doses. It has been an absolute lifesaver!!!!! I've had to do the routine of many days and add in Cipro, so it's one of those cases where you need to be in tune with what's happening with your body to avoid getting that sick."
