Progesterone

Progesterone levels decline faster than estrogen levels during peri-menopause and menopause, resulting in irregular cycles, heavy periods, headaches and mood swings. As a result, progesterone treatment is often preferred over estrogen treatment as the initial therapy for menopausal symptoms. Progesterone has a complimentary effect to estrogen. Progesterone prevents endometrial proliferation induced by estrogen and it is recommended that both be prescribed together.
