The method of taking progesterone to stop bleeding during menopause is to take it orally 12 days before the expected menstruation, 200mg/d, at bedtime, for 12 consecutive days each month, continuing until complete menopause.
Menopause, also called perimenopause, is the period of time between premenopause and one or two years after menopause, when the endometrium undergoes functional changes, the menstrual cycle is prolonged, endometrial bleeding is irregular, and progesterone levels fluctuate over a wide range. Bleeding is usually gradual and decreases, culminating in complete amenorrhea after several years of irregularity.
Progesterone, a natural progestin secreted by the corpus luteum, promotes thickening and congestion of the endometrium. Insufficient progesterone results in irregular maturation and shedding of the endometrium, and persistent bleeding occurs.
Oral progesterone and estrogen work together to promote the thickening and secretion of the endometrium, and to promote the shedding of all the endometrium during menstruation to treat irregular bleeding. Specific medication should be prescribed by your doctor.
