What should you know about tranexamic acid for period cramps?

Tranexamic acid supports clot formation where the womb lining is shedding. This can lessen blood loss during a heavy period. Cramps come from womb muscle contractions, so the medicine does not target the usual mechanism behind cramping.

If cramps are intense, last beyond the bleeding, or have changed from your usual pattern, the cause deserves separate attention. Conditions such as endometriosis, adenomyosis, or fibroids can cause troublesome period symptoms and may need a different assessment.

Keep a brief cycle record: pain location, start and end time, bleeding heaviness, clots, missed activities, and medicines used. This helps a clinician distinguish bleeding control from pain control. Take tranexamic acid only as prescribed and do not use leftover tablets for a new symptom.

Mention any history of blood clots, kidney disease, clotting problems, visual symptoms, pregnancy, or hormonal contraception. Read [Tranexamic Acid](/materials/tranexamic-acid/) for background, and see [Tranexamic Acid for Heavy Bleeding](/treatments/medical-gynaecology/tranexamic-acid-for-heavy-bleeding/) for its gynaecology use.

Get urgent help for chest pain, breathlessness, coughing blood, a painful swollen leg, or sudden visual disturbance. Seek prompt care for severe pelvic pain, fainting, fever, vomiting, pregnancy with pain or bleeding, or bleeding that feels unmanageable.

What is the best option for my cramps? Could another condition explain my symptoms? How should I use tranexamic acid when bleeding and pain occur together?
