Monistat 1 Day Yeast Infection Treatment (6.5 percent of Tioconazole) is a single dose product that may be the perfect solution for busy women. This package contains one ready to use pre filled applicator. It is a preferred option for women who may be sensitive to the ingredients contained in creams or the high dose (1200mg of Miconazole Nitrate) offered in other Monistat 1 products. Monistat is the #1 Doctor and Gynecologist Recommended over the counter (OTC) yeast infection brand and starts working right at the site of infection. While Monistat 1 products offer the most time convenient yeast infection treatment course, most women do not experience relief from the infection in just 1 day. If you do not feel some relief within 3 days, or complete relief within 7 days, stop using the product and consult your healthcare professional.
