Miconazole
"I've used Monistat before with good results. I was a little weary of using it without being 100% sure I had a yeast infection. But I'd had moderate symptoms of itchy and red irritation for a week and I really wanted some relief without spending a butt ton of money. Worst decision of my life. Despite having an okay reaction before, the moment I inserted the first dose of Monistat 7 the itchiness and burning increased horribly. It's now been over 3 hours and it hasn't gotten any better. I can't sleep and the pain is WAY worse than the infection I had before. Never again. I don't know if they changed what was in it or what but I'm sitting here wondering if I can wait the 6 hours until my doctor's office opens or if I need to go the ER."
