Nystatin worked for me the first time I had candida but not the second or third time. A couple of my doctors told me that it is not as strong as some of the natural anti-fungals like olive leaf extract, caprylic acid, GSE. I was told by one candida specialist that olive leaf extract is the most potent of all but it should have a strong % of oleuropein. It is a natural herbal antibacterial, antiviral, antiparasitical, & antifungal.
It is fine to take nystatin along with the natural antifungals.
