In my ongoing quest to eliminate yeast, I ordered Threelac (a dietary probiotic supplement) for my daughter. It arrived today and I see on the box that it is says not to use if taking antibiotics. Of course, my daughter can't stop taking the antibiotics so I am not sure what to do. I believe from searching old posts that some on Cpnhelp have used Threelac. If you used it while on CAP please let me know how you dosed it. I guess what I really need to know is how many hours you took it from the antibiotics and if you feel it helped.
