Hello. I'm taking GSE, Serrapeptase, Cats Claw and Probiotic. I developed bronchitis, and have some Doxy I want to take for it because it has helped me in the past. I've read that GSE cancels the effects of Doxy. Is this true?
I have not heard that. I did put grapefruit and doxy in the drug interaction checker I use...and no interactions came up.
