I was actually taking a proton pump inhibitor (omeprazole) for 6 mo before and while taking clindamycin. I had been wanting to get off it so when I started having my “issues” before I was diagnosed with c diff I just quit the omeprazole cold turkey. I believe that it can contribute to getting c diff as it blocks the acid production. I have changed my diet since so not having the acid reflux as much. I am 3 weeks post Dificid and so far ok. 🤞 I must say that I worry every day that it is going to come back though.
