Tranexamic acid

Tranexamic Acid is a blood clot-inducing medication derived from snake venom and used for heavy menstrual flow. It has several drawbacks: it can only be used for five days, the dose  needs to be adjusted for a person’s body size, and it is taken three times a day. It also carries risks of blood clotting. It is less effective at controlling heavy flow than the levonorgestrel-releasing IUD, and similar to non-steroidal anti-inflammatories or short duration progestins.
