What is it used for?
Tranexamic acid is used to prevent or treat bleeding in the following situations:
- Abnormally heavy bleeding during and after the surgical removal of the prostate gland (prostatectomy).
- Abnormally heavy bleeding during and after surgery on the bladder or cervix.
- Abnormally heavy periods (menorrhagia).

- A hereditary condition called angioneurotic oedema.
How does it work?
- Cyklokapron tablets contain the active ingredient tranexamic acid, which is a type of medicine called an antifibrinolytic. It can be used reduce severe unwanted bleeding, such as heavy menstrual bleeding, bleeding after bladder surgery or heavy nosebleeds. Tranexamic acid tablets are also available without a brand name, ie as the generic medicine.
- Blood clots are made of red blood cells and platelets bound together with a substance called fibrin. Once they have fulfilled their normal purpose of stopping bleeding, the body dissolves clots by producing another substance called plasmin. Plasmin breaks down the fibrin and allows the clots to break up.
- Tranexamic acid stops the production of plasmin by blocking the action of the enzymes that produce it. This reduces the breakdown of fibrin and stops clots dissolving, which in turn helps to reduce bleeding.
- In women who have heavy menstrual bleeding there are higher than normal levels of the enzymes that produce plasmin in the lining of the womb. This causes blood clots in the womb lining to dissolve and increases the volume of blood that is shed with each period. Tranexamic acid stops these blood clots dissolving and so reduces the volume of blood loss. It can reduce menstrual blood loss by up to 58 per cent.
- Tranexamic acid is also used in other conditions where severe bleeding needs to be reduced.
