Tioconazole
"I am 18 and experienced my first yeast infection a few days ago. I read the reviews here after I had already used the Monistat 1 and was terrified. Luckily, I have had great results. After 3 days of YI symptoms, I used Monistat 1 around midnight last night. I did experience some itching during the night but it was totally manageable. I did not experience the intense burning/itching that others described despite having sensitive skin. My skin was somewhat raw but not terrible before using the medication which may have helped. The next morning everything felt completely back to normal (besides discharge which Monistat does say is normal) and the swelling has gone down almost entirely. Only some discharge 20 hours later. Really worked for me!"
