Tioconazole
"After about an hour of having this medicine applied I was experiencing the worst burning sensation of my life. I had to rush home from work to try and get it off of and out of me. I was shaking in pain and was so swollen the next day I was unable to wear pants, and struggled to walk. From what I can tell this kind of reaction is not uncommon with this medicine. Why it is still sold in stores is beyond me. I would never recommend this medicine to anyone."
