I used monistat 1 (tioconazole) to treat a yeast infection 4 days ago and i still have some itching and discharge. is this normal? should i use another treatment?

You could...: Try another 1 day treatment.....or you could see your doctor for confirmation that it's a yeast infection and get a dose of Diflucan (fluconazole) which works very well at eradicating yeast infections in one shot; or if you prefer a prescription cream that works a bit better than the OTC Monistat. Best wishes to you.

Use Monistat 7 for all 7 days and if that doesn't work please bring this up with your Gynecologist who knows your medical history. If you don't have confidence in your Doctor see another for a second opinion.
