Tioconazole
"This was the WORST product I have ever used!  Within an hour of using Monistat 1, I had severe itching and burning.  I was frantic to get it out and resorted to a vinegar wash and a few warm water washes.  I’ve probably now just given myself a bacterial infection on top of everything else, but the itching and pain were SEVERE!!!  I would never recommend this product for anyone.  STAY AWAY!!!!"
