Hormone replacement therapy (HRT) is used in menopausal women to alleviate symptoms of estrogen deficiency and may be administered in various forms, including pills, creams, and patches. Types of HRT include estrogen-only, progestin-only, and combinations aiming to prevent osteoporosis and maintain quality of life, but it carries risks such as endometrial cancer and venous thromboembolism. Nurses play a crucial role in monitoring patients for these risks and assessing their medical history prior to starting HRT.
