Bleeding, whether it's caused by heavy menstruation, surgical procedures, or trauma, poses health risks if left uncontrolled. Unlike other treatments like puberty blockers or progestin-only pills (POP), tranexamic acid operates specifically on blood flow, making it a distinct option in bleeding management.
How it works
Tranexamic acid, often abbreviated as TXA, is an antifibrinolytic agent. It works by blocking the breakdown of blood clots, helping to stabilise and maintain clots which control bleeding. This makes it particularly useful when excessive bleeding can lead to complications.
Uses
Menstrual bleeding: TXA reduces bleeding without interfering with the hormonal processes driving menstruation, so it provides a targeted solution to alleviate symptoms. This can be prescribed to people who have heavier-than-usual periods, known as menorrhagia.
Post-surgery: People are at a greater risk of bleeding after surgery, which can slow healing and increase the risk of complications.
Accidents and injuries: Accidents and injuries can cause heavy bleeding, so TXA is used to prevent shock and organ damage. It gets to work quickly, so is excellent in an emergency situation.
TXA to stop menstruation
TXA effectively reduces bleeding, but it doesn't stop menstruation altogether. Unlike puberty blockers or progestin-only pills, which affect the hormones responsible for menstruation, TXA only affects bleeding. Because of this, it's not suitable for long-term management of suppressing periods for gender-affirming care.
