Tioconazole
"Oh my let me just say if you want to feel like your are wearing a jalapeno pepper as a tampon then this product is for you. This was by far the worst product out there for yeast infections. I had to run to the shower use the shower head and put cold water on my vagina just to cool it off. The next day she was sore and felt no  more burning sensation, but boy was that horrible the day before. Next time I am doing a 7 day. Not worth the burn."
