Yeast infections are common. The treatment for yeast infections is over-the-counter topical regimens, such as Gynelotrimin or Monistat, or a pill form of treatment known as Diflucan. Diflucan is available by prescription only. The over-the-counter topical treatments have all been shown to be safe during pregnancy. Diflucan, however, has not been adequately studied in pregnancy, and is not used in the pregnant patient. Therefore, it is fine to treat yeast infections with topical medications only. However, if this is your first yeast infection, it is best to see your physician and get an actual diagnosis before self-treating. Please discuss this further with your physician.
