I don’t know. You may want to get someone more knowledgable to answer that. I take a probiotic with 50 million in it, but I don’t take that one so I don’t know. I think you should definitely be taking a probiotic if you are taking diflucan. To tell you the truth, I think MOST of us should be taking a probiotic, even healthy people. We just take so many medicines and eat so many foods that damage our systems.
