Tioconazole
"Prior to using this product I was actually afraid because of so many of the reviews talking about the extreme pain they experienced. The first time I used Monistat 1 was in college and I was desperate for relief. I went into it fully expecting to be in pain but was really happy to find that none existed whatsoever. It cleared up my symptoms in about 48 hours. I have use it 3 times since the first and not once had any pain. I really think it's about knowing your body and what you can and can't handle. I'm sure there are chemicals that many people might be allergic to. All I can say is this product is great if you want a quick fix and relief."
