Patient leaflet - Tranexamic Acid 500 mg tablets
1. What Tranexamic Acid is and what it is used for
Tranexamic Acid 500mg Tablets (hereinafter referred to as Tranexamic Acid) are an antifibrinolytic agent used to reduce bleeding. When you bleed your body forms clots or plugs as part of healing. In some people these plugs do not stay in place long enough. This can cause too much bleeding. Tranexamic acid helps these plugs to stay in place.
Tranexamic acid can be used to prevent or reduce bleeding for a short period of time in many different conditions. You could have been prescribed this medicine for one of the following reasons:
- following prostate surgery
- heavy periods
- nose bleeds
- surgery to the cervix in women
- bleeding inside the eye
- tooth removal in haemophiliacs
- a hereditary disease called angioneurotic oedema (HANO).
