The majority of tranexamic acid tablets do not affect menstruation. Tranexamic acid is mainly a hemostatic drug that shortens the clotting time, so it will stop bleeding. The effects on menstruation are often due to endocrine reasons, or due to certain diseases such as polycystic ovary syndrome, pelvic tuberculosis or uterine malformations, which may affect menstruation. Therefore, once the menstrual cycle changes, the time of menstruation changes or the volume of menstruation changes, it is recommended to have a timely examination, such as sex hormone six, thyroid function test, ultrasound, etc. to understand the cause of menstrual disorders, and if necessary, it is also recommended to have a diagnostic curettage to understand the cause of menstrual disorders before giving treatment.
