What this interaction means in plain words
Ethinyl estradiol-norgestimate and Tranexamic acid are not normally used together. Taking them at the same time is expected to cause harm or make one of them unsafe, so a different medicine is usually chosen for one of the two.

Why it happens
Additive prothrombotic effects from estrogen-induced coagulation changes and antifibrinolysis.
