Tioconazole
"Ladies, please be advised some of the ingredients in Monistat 1 may be what you are allergic to. So sorry to hear of all the bad experiences. This is my third time using Monistst 1 and each time it has cleared up my yeast infection. This time, I just got done taking 10 days of antibiotics and I was popping pro biotic 8 to counter the antibiotics killing both my good and bad bacteria. Probiotics are excellent to keep from getting a yeast infection while taking antibiotics. However, yesterday I had a Colposcopy and Biopsy after I had an abnormal pap. Next day, yeast infection. :( Popped this Monistat1 in and it's practically and instant relief."
