Tioconazole
"I got my first yeast infection when I was 16, my mom went and bought me monistat 7 and it worked great I felt better within a day. About two months ago I got the symptoms of a yeast infection but without the discharge. Unsure of what I had I went and bought monistat 7 again and it burned and itched worse than anything I've felt. I bawled my eyes out and it didn't stop for hours. I continued to take it for 2 more nights with the same symptoms and then went to the gyno that Monday. Turns out I had a bacterial infection and that is why it was burning so horribly. If it burns you to the point where you are In tears GO TO THE DOCTOR! It is probably not a yeast infection!"
