Miconazole
"Had a yeast infection for about 4 days when I decided to try Monistat one last time. I had used it in the past with the burning and itching but it was mild. Holy on fire vagina!!! It feels like I used a fire brand as a tampon! They have had to change the formula. I had level 3 endometriosis and a child through natural childbirth and this stuff is right up next to those pains. After 30 min I was on fire and in so much pain! Put the box down ladies call a clinic or go to your Dr and just get the yeast infection medicine - this stuff is not with it! If your like me and googling "is this normal" or "will I die" and you've already inserted the little bead from hell, grab an ice pack and breath through it."
