Tioconazole
"I haven't had a YI in years but thanks to my partner (who didn't tell me he had symptoms) I felt one coming on with mild itching. I remember monistat from my younger years and decided that I better get it/take it instead of go the usual natural route.  Back in the day it would leak out and work starts on Monday so I paid the +- 20 bucks. Well I suppose they have fixed the leaking problem and added an ingredient that I along with many others must be allergic to. I had extreme itching last night and it was no picnic. I am still itching badly after 12 hours.  I am taking a probiotic and praying I don't end up with a worse YI or a bacterial infection.  I hope it goes away because the itch/burn I don't want to have to deal with at work"
