Tioconazole
"So I've been on penicillin the past few days for dental work and then the dread YI happened. Few years since my last one but I'm going away in 2 days & the LAST thing I need was to be uncomfortable on plane! I remember using the 3 day years ago & couldn't remember anything aside from the YI clearing up. So I bought the 1 day. Man do I wish I would've read this! Within 30 minutes I was on fire.  Annoyed at myself for giggling and being carefree just 30 mere moments before I put that egg in.  I was up & down all night in more discomfort than I began with. But 10 hours later the pain has subsided to the point I function as a normal human. Good Luck Ladies there is a light at the end of this painful tunnel."
