Tioconazole
"I got a mild yeast infection 2 weeks after I had finished an antibiotic for bv.. I inserted the Monistat 1 at around 11pm and went to bed directly following insertion.. I was rudely awaken at 2am with intensive itching and burning more so than I had before I had used the product. I was literally sobbing in so much pain. I proceeding to soak in a cool bath which seemed to help the itching and burning"
