Monistat actually causes serious pain and burning against my skin. I always thought it was just the infection getting pissy from the irritated skin and that the pain was somehow normal and that all women had to deal with it. I finally discussed it with my doctor and it's apparently a rare skin allergy to the medication. So imagine having the normal pain/itch of the irritation followed by OMFGMYCOOCHISONFIREGETITOUTGETITOUTGETITOUT!!!

I now have to have the doctor's office call in a prescription whenever a yeast infection even begins to rear it's ugly head. I don't know if it's the same stuff you've mentioned, but it does the trick.
