A recommendation from a ND I once saw about taking Antibiotics : If you end up having to take Antibiotics , take Sachromyces Boulardi at the same time. S. Boulardi, a transient, good yeast, will take up space in the intestines and compete with Candida during the time you are taking Antibiotics (you don't want to leave Candida unopposed). Also, do take probiotics while on antibiotics, just space them 2 hours away from when you take a dose of antibiotics. And, obviously, when you you are done with the antibiotics take plenty of probiotics.
