Tranexamic acid is used to prevent or reduce excessive bleeding for a short period of time in many different conditions such as heavy menstrual bleeding (menorrhagia) or in those with certain disorders like haemophilia (a rare bleeding disorder in which the blood does not clot properly).
This medication belongs to a class of drugs known as anti-fibrinolytics, which prevents blood clots from breaking down and hence, reduces the amount of blood lost.
