Conjugated Estrogens
Summary
Conjugated Estrogens are used to treat symptoms of menopause like hot flashes and vaginal dryness. They are also used to prevent osteoporosis in postmenopausal women, manage symptoms of low estrogen in young women, and for palliative treatment in certain types of breast and prostate cancer.
Conjugated Estrogens work by replacing the estrogen that the body no longer produces after menopause. They bind to estrogen receptors in various tissues, helping to regulate hormonal balance, reduce menopausal symptoms, and maintain bone density.
For adults, the starting dose for menopausal symptoms is typically 0.3 mg daily, which may be adjusted based on individual response. The medication is usually taken orally, with or without food.
Common side effects include nausea, vomiting, headache, and breast tenderness. Serious adverse effects can include blood clots, stroke, and increased risk of certain cancers.
Conjugated Estrogens increase the risk of endometrial cancer, blood clots, stroke, and breast cancer. They should not be used by people with a history of these conditions, or by pregnant women. Regular monitoring by a healthcare provider is essential.
