Miconazole
"-1 -- do not purchase this OTC yeast meds. I got 3-day M. for a self diagnosed yeast infection. 3 day prefilled applicators. First two days were not as bad as tonight, the 3rd dose. I completely agree with every entry here "MY VAG IS ON FIRE" insane burning feeling. No relief. I tried to pee, and it hurts - it's definitely after applying the meds. And this happens immediately. 
Dropped to the floor from the burn and discomfort. I don't believe any medicine in the world should cause so much suffering before it works or gets better. Do not try this unless you are trying to hurt yourself. 
Sincerely - Oakland CA."
