Miconazole
"Well I had a YI about 8 months ago and decided to use Monistat 7. Yes, it burns like hell!! But only because it's working. As the days go by the burning and itching will diminish. By day 5 I hardly felt anything. And on day 7 I was back to normal. About a week ago I started with another YI and decided to use the 3 day. Didn't work. Had to go back and get the 7 day treatment. Again, it burns and itches like crazy, but because I've used it before I know it will pass. It is very uncomfortable, but hang in there. It does work if you use it everyday the way it says. "
