Heavy period and tranexamic acid: what to know

During a period, the lining of the uterus sheds and small blood vessels can bleed. Tranexamic acid slows the breakdown of clots at those vessels, which can lessen blood loss while you take it. It does not regulate ovulation, treat fibroids, or explain why bleeding is heavy. A clinician may ask about previous blood clots, kidney problems, vision symptoms, pregnancy plans, and medicines before recommending it.

Use tranexamic acid only as directed on the label or prescription, usually during the days when bleeding is heaviest. Do not share tablets or increase the amount because bleeding continues. Keep a record of when bleeding starts, how often you change products, clots, pain, and missed activities. Discuss other options if bleeding remains heavy, returns between periods, or causes tiredness; testing may look for anaemia or a uterine cause.

Seek urgent medical help for chest pain, sudden breathlessness, coughing blood, one-sided leg swelling or pain, or a sudden change in vision while taking tranexamic acid. Arrange prompt assessment if bleeding soaks through products repeatedly, you feel faint, or severe pelvic pain accompanies the bleeding. Heavy bleeding itself deserves review when it is new, persistent, or disrupting daily life.

Ask whether tranexamic acid fits your medical history, which days to take it, what to do after a missed dose, and how to recognise a clot-related warning sign. Ask what evaluation is needed if it does not help.
