What is the most important information you should know about PREMARIN Vaginal Cream (a cream of estrogens)?

  • Estrogens increase the chances of getting cancer of the uterus.

  • Report any unusual vaginal bleeding right away while you are using PREMARIN Vaginal Cream. Vaginal bleeding after menopause may be a warning sign of cancer of the uterus (womb). Your health care provider should check any unusual vaginal bleeding to find out the cause.

  • Do not use estrogens with or without progestins to prevent heart disease, heart attacks, strokes, or dementia.

  • Using estrogens with or without progestins may increase your chances of getting heart attacks, strokes, breast cancer, and blood clots.
