What should you know about tranexamic acid for stopping periods?

During menstruation, the womb lining sheds and small blood vessels open. Tranexamic acid helps clots remain in place by slowing their breakdown, which can reduce flow. It is generally used during the bleeding days according to a prescriber’s instructions, rather than as a way to delay a period or change the menstrual cycle.

Heavy bleeding can have several causes, including fibroids, adenomyosis, hormonal changes, bleeding disorders, medicines, or pregnancy-related problems. Reducing flow does not identify or treat the underlying cause, so recurring or new heavy bleeding deserves assessment.

Follow the prescribed dose and timing, and do not take extra tablets to make bleeding end faster. Tell your clinician about previous clots, kidney disease, vision problems, pregnancy, hormonal contraception, and all medicines. Track how often you change pads or tampons, flooding, clots, pain, and bleeding between periods; this helps guide the review. Seek advice if the medicine does not control the pattern you were told to expect.

Get urgent medical help if you are soaking through protection repeatedly, feel faint or short of breath, have severe worsening pelvic pain, or may be pregnant. Emergency symptoms after taking tranexamic acid include chest pain, trouble breathing, coughing blood, one-sided leg swelling, sudden weakness, or a new vision change.

Ask what is causing the bleeding, which days to take the medicine, how to judge whether it is helping, and whether another treatment or blood test is needed. Mention plans for pregnancy and any hormonal method you use.
