Surprise use: Providing relief for itching, burning and irritation affecting your feet, or your husband's man parts, or your child's baby parts.
"Miconazole, the antifungal agent in Monistat, is an effective treatment for athlete's foot as well as jock itch," says Isaac M. Neuhaus, MD, assistant professor of dermatology at the University of California in San Francisco. The different yeasts causing these infections are all part of the same family. Feet usually take about a month to respond to twice-daily applications, while your partner should experience relief in two weeks, and your baby's diaper rash should clear up in a few days. (Keep in mind that this doesn't work both ways, and you should never use medication on your vagina that wasn't specifically formulated for that area).
