Miconazole
"WHERE'S THE LAWYERS?! Over the years I've had YI, and have used Monistat each time (or a generic of it) without issue. This time was unbelievably awful. After inserting the ovule, two hours later I woke up to unholy itching, much much worse than the YI! The burning wasn't quite as extreme as some of the other users, but it did burn! There was no sleep to be had, so I took two Benadryl in hopes it would work...and it did thank God! After an hour I was finally able to return to bed and fall asleep. Throughout the next day I have had some swelling, but the pain and itch are nearly gone."
