Functional uterine bleeding is abnormal uterine bleeding, i.e., the interval, duration and amount of bleeding of menstruation are different from normal menstruation due to uterine diseases and other reasons. Commonly used drugs in clinical practice include progestins, compound oral contraceptives, and androgenic drugs, etc. 1. Progestogens: such as progesterone and dydrogesterone are used for patients with certain hormone levels in the body, which can achieve the effect of stopping bleeding by promoting the transformation of the endometrial cycle, and may have side effects such as nausea and vomiting, breast distension and pain, and may cause withdrawal of bleeding after discontinuing the medication. 2. Compounded oral contraceptives: such as ethinyl estradiol and cyproterone tablets, can be used for long-term and severe anovulatory abnormal uterine bleeding. There may be side effects such as weight gain, high blood pressure, hair loss, and they are contraindicated in people with a history of blood clots and cardiovascular disease. 3. Androgenic drugs: Used to assist in hemostasis, they can strengthen uterine smooth muscle tone, slow down the speed of abnormal uterine bleeding, and have a certain hemostatic effect. There may be side effects such as endocrine disorders, thickening of voice, acne and beard growth after taking them. Be sure to choose the right medication for your condition under the guidance of a professional doctor.
