Tioconazole
"I am 19 years old and dealing with my first YI. I went to the doctor today thinking I had a UTI and when the screening came up negative they had to open me up and check for STD's and a YI (traumatic). I discovered that I had a YI and had been experiencing symptoms for a week. I was laying in bed and around 11 i decided to  get monistat. I went home and by 11:20 I inserted the bead. I then went to bed and began to read reviews. I saw that most of the users of this product had terrible burning that would bring them to tears. I was  freaked out bc i have very sensitive skin and was bracing myself for the awful experience. I woke up in the morning and had no burning, no swelling, and no side effects. maybe I am lucky but this worked 4 me"
