Algestone is a synthetic progestin that suppresses ovulation and alters the uterine lining, while estradiol provides estrogenic effects and helps regulate the menstrual cycle. Together, they prevent fertilization primarily by inhibiting ovulation and thickening cervical mucus.
This combination should not be used by individuals with known or suspected pregnancy, history of thromboembolic disorders, or certain hormone-sensitive conditions. Patients should be monitored for cardiovascular events, mood changes, and other hormonal side effects. Not all formulations containing algestone/estradiol are available in every country.
