Tranexamic acid is a medication used to treat or prevent excessive bleeding in various situations by helping the blood to clot more effectively[1]. Its primary medical uses include treating heavy menstrual bleeding, reducing bleeding following major trauma, during surgeries with a high risk of blood loss, for nosebleeds, and to decrease bleeding after childbirth[1].
For heavy menstrual bleeding, tranexamic acid is commonly prescribed in tablet form and taken during the period to reduce the amount of blood loss. It is usually taken three times a day for up to five days, starting when menstruation begins[2][5][4]. This use is supported by studies showing improvements in quality of life and effectiveness comparable to other treatments for abnormal uterine bleeding[1].
In trauma care, tranexamic acid is important for reducing the risk of death caused by significant bleeding, especially if administered within the first three hours after injury. It has proven benefits after major trauma and in cases of traumatic brain injury[1].
Tranexamic acid is also used post-surgically, after dental procedures (such as mouthwash after tooth extraction), and for hereditary or acquired conditions that increase bleeding risk[4].
The drug is available in various forms, including tablets, mouthwash, and intravenous injections—though injections are usually reserved for hospital use. Popular brand names include Lysteda and Cyklokapron[1][3][2].
Tranexamic acid works by slowing or stopping the breakdown of blood clots, thereby reducing or preventing hemorrhagic episodes, particularly in cases involving hyperfibrinolytic disorders[3][6][7]. Most people do not experience serious side effects, but rare risks include blood clots, vision changes, or allergic reactions[4][6].
