Side effects? The most experienced side effects of all hormonal therapy are menopausal symptoms (ie. Hot flashes, etc). There is a small increased risk of blood clots similar to hormone replacement therapy, in women with an intact uterus, there can be irreg bleeding and thickening of the uterine wall. If ignored this can rarely progress to uterine cancer that can be cured with a hysterectomy.
