Tranexamic Acid for Heavy Bleeding

Tranexamic acid helps reduce heavy menstrual bleeding by supporting clot stability during a period.

Tranexamic acid is a medicine that helps clots remain in place. During menstruation, the womb lining releases substances that break clots down; tranexamic acid slows that process, which can reduce blood loss. It does not contain hormones and is usually taken only during the days of heavy bleeding, following a clinician's directions.

The medicine is intended to reduce bleeding during the period in which you take it. Some people notice lighter flow during the first treatment cycle, while the response can be clearer after the plan has been used as directed across subsequent cycles. It does not remove a fibroid or treat the underlying cause of bleeding.

Possible effects include nausea, vomiting, diarrhoea, headache, or stomach discomfort. Taking tablets as directed can help limit problems. Seek urgent medical help for chest pain, sudden breathlessness, coughing blood, a painful swollen leg, or sudden changes in vision, because these may signal a serious clotting or other problem.

You generally take it for part of each menstrual period rather than every day, for the number of days prescribed. The treatment may continue over several cycles while the cause of bleeding is assessed. Do not take extra doses or extend the course to compensate for bleeding that remains heavy.

Take the tablets exactly as prescribed and swallow them with water. Tell the prescriber about previous blood clots, kidney problems, vision problems, pregnancy, or medicines that affect clotting. Keep a simple record of bleeding, pain, flooding, clots, and missed activities; it gives the next review useful detail.

A clinician may offer tranexamic acid to someone whose periods are unusually heavy, particularly when there is no immediate need for a hormonal treatment or while investigations continue. Heavy periods can occur with uterine fibroids or adenomyosis and may contribute to iron-deficiency anaemia. The medicine reduces bleeding but does not explain why it is happening.

Use the prescribed schedule from the start of heavy flow. Take each dose at its instructed interval, continue only for the planned days, and keep the medicine away from children. If you forget a dose, follow the product instructions or ask a pharmacist; do not take two doses together unless specifically told to do so.

There is no recovery period because tranexamic acid is taken by mouth. Many people use it only during menstruation and carry on with usual activities. Arrange review if bleeding remains disruptive, returns between periods, occurs after sex, or causes tiredness, dizziness, or breathlessness.

Get urgent help for severe weakness or fainting, very heavy bleeding with dizziness, chest pain, sudden shortness of breath, coughing blood, or one-sided leg swelling and pain. Contact your clinician about persistent nausea, troublesome headaches, or any visual change. Do not restart the medicine after a suspected clot without medical advice.

Depending on the cause and your preferences, care may include an anti-inflammatory pain medicine, hormonal treatment, an intrauterine system, or treatment directed at fibroids or adenomyosis. Blood tests may check for iron deficiency, and treating anaemia may be needed alongside reducing menstrual blood loss.

A gynaecologist or primary-care clinician can assess the pattern of bleeding, review medicines and clotting risks, and decide whether tranexamic acid fits your needs. Take a list of medicines and describe how often you change pads or tampons, whether clots occur, and whether bleeding affects sleep or work.
