  • What is the most important information I should know about Estrasorb?

    Estrogens increase the chances of getting cancer of the uterus. Report any unusual vaginal bleeding right away while you are using Estrasorb. Vaginal bleeding after menopause may be a warning sign of cancer of the uterus (womb). Your healthcare 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 attack, stroke, or dementia. Using estrogens with or without progestins may increase your risk of heart attack, stroke, breast cancer, and blood clots. Using estrogens with or without progestins may increase your risk of dementia, based on a study of women age ≥65 years. You and your healthcare provider should talk regularly about whether you still need treatment with Estrasorb.

  • Who should not take Estrasorb?
