Fluconazole
"I had a yeast infection. I took the 150mg Diflucan yesterday at lunch. I have no smell or itching as of this morning. It works fast BUT the side effects hit me hard. I have had stomach pains on & off all night and my heart rate has went up 3 times and stays up for around 30 minutes each time since yesterday evening. No rashes though. If you can deal with the side effects, I'd say it is an effective medicine that works fairly quick."
