Estradiol didroxyprogesterone tablets can supplement the lining. Estradiol didroxyprogesterone tablets are a combination of estrogen and progestin and are taken in a cycle sequential manner. The white or red tablets in the first half of the cycle are 17-beta estradiol, and the gray tablets in the second half of the cycle contain both 17-beta estradiol and dydrogesterone. The first half of the cycle focuses on taking estrogen to repair the lining, while the second half of the cycle repairs the lining while promoting menstruation. If a woman has had an abortion or a curettage and her endometrium has been damaged, she can take oral estradiol and drospirenone tablets to repair her endometrium and adjust her menstrual cycle.
