The first thing that I did and that I recommend patients do if they have to take antibiotics is, along with and immediately after doing high-dose probiotics, so let's say you have to get on antibiotics for two weeks because your life is threatened or your child's life is threatened, you want to take about 400 CFUs of probiotics daily or about a trillion daily in some cases. That's what you want to do is typically get on at least one if not two probiotics, very high doses, again, pay attention to dosage, and then you want to stay on for at least a year or two on probiotics afterwards at maybe 100 billion or so daily.
