That is the protocol that is mostly used Flagyl 450 MG three times a day and Cipro 450 MG two times a day. I have been on that so many times and can barely function while taking it. It’s like they are trying to kill you in the process of getting rid of the diverticulitis flareup. Every time I have to go on the antibiotics to treat the diverticulitis can barely stand it. Hope you can get rid of the flareups without having to take this crap.
