What should you know about tranexamic acid and birth control?

Tranexamic acid and birth control should be reviewed together because some contraceptive choices and personal clotting risks can affect the safety of treatment. Do not assume that every form of birth control is interchangeable when tranexamic acid is being considered. A clinician needs to know the exact contraceptive, the reason for tranexamic acid, and your history of clots, migraine, kidney disease, pregnancy, or recent surgery.

Tranexamic acid supports clot stability, while some contraceptives can also influence clotting risk. That does not mean a serious problem will occur, but it does mean the combination should be assessed rather than self-started. Non-hormonal and progestogen-only options may have different considerations from oestrogen-containing contraception.

Bring the contraceptive packet or name, including whether it is a combined pill, patch, ring, injection, implant, or intrauterine method. Explain whether tranexamic acid is for heavy bleeding or a skin condition, and list medicines and supplements. Keep taking prescribed contraception unless the prescriber gives a different instruction. See [Tranexamic Acid](/materials/tranexamic-acid/) and [Tranexamic Acid for Heavy Bleeding](/treatments/medical-gynaecology/tranexamic-acid-for-heavy-bleeding/) for context.

Seek emergency care for chest pain, sudden breathlessness, coughing blood, one-sided leg pain or swelling, weakness on one side, or a sudden change in vision. Ask for prompt advice if you become pregnant, develop a severe headache unlike your usual pattern, or have bleeding that is not controlled.

Ask whether your contraceptive contains oestrogen, whether another option would suit your bleeding plan, how long to use tranexamic acid, and which warning symptoms matter for you.
