Estrogens, with or without progestins, should not be used for the prevention of cardiovascular disease or dementia (decline in memory or thinking skills). Estrogen and progestin therapy has shown an increased risk of breast cancer, heart attack, and blood clots. Estrogen therapy, with or without progestins, increases the risk of stroke and dementia. Estrogen therapy alone increases the risk of cancer of the uterus (womb).

Elestrin should not be used if you have unusual vaginal bleeding; currently have or have had certain cancers, including cancer of the breast or uterus; had a stroke or heart attack in the recent past; currently have or have had blood clots; currently have or have had liver problems; or think you may be or know that you are pregnant.

The most frequently reported adverse events in clinical trials were nose and throat irritation, breast tenderness, upper respiratory tract infection, and irregular menstrual bleeding.

You and your healthcare provider should discuss whether Elestrin is right for you or whether you still need treatment with Elestrin.

Estrogens, with or without progestins, should be prescribed at the lowest effective doses and for the shortest duration consistent with treatment goals and risks for the individual woman.
