Tioconazole
"I get yeast infections pretty frequently because I have a compromised immune system. I have used this product several times, and this is the second time I have had a bad reaction to it. About an hour and a half after insertion I started experiencing deep itching/stabbing feelings... Basically REALLY intense itching and a small amount of burning. To the point I wanted my fiancé to knock me out until it was over. I don't know what my other options are, but I don't think I'm going to use this product anymore. It's been 4 hours now (about) and I'm able to at least think and move, but it is still itching/burning. Really miserable. Will be telling my ob about this on Friday. I think I'm pregnant. I hope this doesn't mess with anything."
