Both miconazole (Monistat) and clotrimazole (Gyne-Lotrimin) are effective in treating yeast infections. These products, which used to be available only by prescription, are available over the counter in pharmacies and many variety stores.
Apply the medication as directed in the package insert. Complete the full course of treatment, as specified in the insert; do not stop using the medication early, even if your symptoms subside. If you find that you frequently get a yeast infection around the time of your menstrual period, try using one of these antifungal creams a few days before and/or after your menstrual period as a preventative.
