Tioconazole
"So here's the deal. Don't take this unless you know you have a yeast infection! Bought this one since it seemed the least amount of time would be involved. Then I went home and read reviews. Everyone is warning about this INTENSE and HORRIBLE burning and itching they felt which actually made me hold off for a few days. If you do not have a diagnosed YI then this is going to BURN. Otherwise it's is going work like a charm. About ten minutes after putting this in before bed, I did feel a little bit of itching but not even enough to want to scratch. I fell asleep within 15 minutes and slept through the night. I had a diagnosed YI. I had NO BURNING. I had very little itching. This product is going to hurt if you don't have YI!!!!!"
