I take yeast infection no more at the first sign of a yeast infection. It is the only product I have used that starts to relieve symptoms right away. Most over the counter products work eventually, but you don’t see any relief for a few days. That is entirely too long to wait for relief. Yeast infections are very uncomfortable, and if there is a product that will start to relieve symptoms right away, I am going to use it. The itching and burning is enough to drive me crazy. It’s nice to get some relief right away.
