Delayed menstruation can be induced by oral medication, such as progestin or progestin combined with estrogen.
1. Progestogens, such as progesterone capsules and dydrogesterone tablets. These drugs can make the proliferative phase of the endometrium into the secretory phase, which can encourage the endometrium to shed, and therefore can play a role in promoting menstruation.
2. Progesterone combined with estrogen, recommended oral combination of estrogen tablets combined with dydrogesterone tablets, or estradiol valerate tablets combined with progesterone capsules. After stopping the medication, the endometrium can shrink and shed due to the loss of hormonal support, and menstruation can come.
Oral progestin alone is suitable for women who have some estrogen in their body, and it is effective only when the thickness of endometrium reaches more than 0.8 cm; if the estrogen is low and the endometrium is less than 0.8 cm, it is necessary to take the combined treatment of estrogen and progestin.
The above medicines should be used under doctor’s instruction, and contraindications such as pregnancy, abnormal liver and kidney functions should be excluded before taking medicines. Some women may have nausea, loss of appetite, edema, etc. during the period of taking the medicine, but the symptoms can disappear after stopping the medicine.
