WHAT IS THE MOST IMPORTANT INFORMATION I SHOULD KNOW ABOUT CENESTIN (synthetic conjugated estrogens)
(SYNTHETIC ESTROGEN MIXTURE)?

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

Report any unusual vaginal bleeding right away while you are taking estrogens. 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.

What is Cenestin (synthetic conjugated estrogens) ?

What is Cenestin (synthetic conjugated estrogens) used for?

Cenestin (synthetic conjugated estrogens) is used after menopause to:

  •  reduce moderate to severe hot flashes.
    Estrogens are hormones made by a woman's ovaries. The ovaries normally stop making estrogens when a woman is between 45 to 55 years old. This drop in body estrogen levels causes the "change of life" or menopause (the end of monthly menstrual periods). Sometimes, both ovaries are removed during an operation before natural menopause takes place. The sudden drop in estrogen levels causes "surgical menopause".
    When estrogen levels begin dropping, some women develop very uncomfortable symptoms, such as feelings of warmth in the face, neck, and chest, or sudden strong feelings of heat and sweating ("hot flashes" or "hot flushes"). In some women, the symptoms are mild, and they will not need estrogens. In other women, symptoms can be more severe. You and your healthcare provider should talk regularly about whether you still need treatment with Cenestin (synthetic conjugated estrogens) .
  •  treat moderate to severe dryness, itching, and burning in and around the vagina.
    You and your healthcare provider should talk regularly about whether you still need treatment with Cenestin (synthetic conjugated estrogens) to control these problems.
