Miconazole
"18 years old and dealing with my second YI. The first time I went straight to Monostat 3 and it worked great without any pain. This time I went for the generic expecting the same experience and boy was I wrong. This is the first night and 5 minutes after hopping into bed the burning began. When it didn't stop after 10 minutes I jumped to google and found this page. I'm glad to know I'm not the only one with this issue but VERY angry they didn't say this could happen on the box! A nice "if you're willing to go through fire to get rid of your YI, then this is for you" would have sufficed. I'm wondering if it has something to do with the product being generic? Has anybody else encountered this?"
