Patient Education


Hormone Replacement Therapy

Menopause is the time in a woman's life when her period stops. It is a normal part of aging. In the years before and during menopause, the levels of female hormones can go up and down. This can cause symptoms such as hot flashes, night sweats, pain during sex, and vaginal dryness. For some women, the symptoms are mild, and they go away on their own. Other women take hormone replacement therapy (HRT), also called menopausal hormone therapy, to relieve these symptoms. HRT may also protect against osteoporosis.

HRT is not for everyone. You should not use HRT if you:

There are different types of HRT. Some have only one hormone, while others have two. Most are pills that you take every day, but there are also skin patches, vaginal creams, gels, and rings.

Taking HRT has some risks. For some women, hormone therapy may increase their chances of getting blood clots, heart attacks, strokes, breast cancer, and gallbladder disease. Certain types of HRT have a higher risk, and each woman's own risks can vary, depending upon her medical history and lifestyle. You and your health care provider need to discuss the risks and benefits for you. If you do decide to take HRT, it should be the lowest dose that helps and for the shortest time needed. You should check if you still need to take HRT every 3-6 months.
