A yeast infection is caused by excessive growth of naturally occurring fungus in the vagina or mouth. There are no over-the counter treatments for oral yeast infections. Over-the-counter medications for vaginal yeast infections are available as tablets and creams that are inserted into the vagina. Creams are also available for the outside of the vagina to soothe external burning and irritation. The length of yeast infection treatments can vary from one to seven days. The choice of over-the-counter product depends on your preference for cream or tablets, the length of the treatment (one, three or seven days) and cost. Examples of these products include clotrimazole (brand name Gyne-Lotrimin®) and miconazole (brand name Monistat®). Contact your physician if your symptoms don’t improve after your over-the-counter treatmentâ€”this may be a sign that you have a medical problem other than a yeast infection.
