Deferiprone tablets are a progestin medication that can cause the endometrium to change to a secretory phase. If the medication is suddenly stopped for about a week after taking the dydrogesterone tablets, it will cause the endometrium to shed, which is medically known as pharmacological scraping, and will be able to shed the thickened endometrium and prevent the endometrium from continuing to grow. This is because if the endometrium is too thickly proliferated, it can easily cause the patient to have heavy menstrual periods and also lead to lesions of the endometrium. Therefore, if endometrial thickening occurs in menopausal or postmenopausal women, a diagnostic curettage and then a pathological examination to see what causes it is also needed.
