Tranexamic Acid (TXA)

Tranexamic acid is used to treat heavy menstrual bleeding in women.



Tranexamic acid is an antifibrinolytic agent. It works by blocking the breakdown of blood clots. This means the blood clots you make stick around longer which means you bleed less.


It belongs to a class of drugs known as antifibrinolytics.


Tranexamic acid is not a hormone. It does not treat other menstrual or pre-menstrual symptoms. It does not stop your period. It is not a form of birth control and does not protect against sexually transmitted diseases.


Dosage:

  • two tablets (650 milligrams per tablet) three times a day in the morning, afternoon, and evening.

  • the tablets should not be taken more than 5 days in a row for each monthly period.


Don't take TXA if you have:

  • bleeding in the brain

  • blood clotting problems

  • kidney disease

Do not take this medicine with any of the following medications:

  • estrogens

  • birth control pills, patches, injections, rings or other devices that contain both estrogen and a progestin
