Miconazole
"I got a yeast infection and so I bought this hoping it would clear it up quickly. I usually take diflucan, but it was a weekend and I couldn't get to the doctor.  Inserted the ovule at 11pm and by 3 am my hoo-ha was on FIRE! It was the most excruciating pain and burning I have ever felt down there. I wiped it all away as much as possible and flush/rinsed with warm water. I took some Benadryl and put diaper cream on my inflamed lady bits. The burning has gone down quite a bit, but I am still in a lot of pain. I will never take monistat again! Their website says a "small percentage" of women are allergic. I think it's more than they are telling us! DO NOT use this for a YI. You will be sorry!"
