My son had a stool analysis done and the results show large yeast. Therefore, we are preparing to do an antifungal treatment. I am just wanting advice from anyone that has done an antifungal treatment. The main thing I am wanting to know is what was used, for how long, in what dosage and what the die-off effects were. We are looking at S. Boulardi, Nystatin, Diflucan as our main options. Thank you for any help.
