Tioconazole
"I have had yeast infections before and used Monistat treatment....Although it's been a long time since I've had one. Anyways, I went to the doctor for itching and was diagnosed with a yeast infection. She gave me the pill to clear it up. A few days later I was still itching so I picked up the Monistat 1 day treatment. I inserted it at midnight and within a hour woke up burning inside. I douched with warm water and went and laid back down and now four hours later I'm sitting in hot water in the bath tub. They must have changed the ingredients on this product. I'm praying the burning eases up soon. I can't sleep and I'm on fire inside. This product will never touch my body again after today!"
