摘要
Oral tranexamic acid is antifibrinolytic and ethinylestradiol is prothrombotic. Together they raise the risk of venous and arterial thrombosis, and oral tranexamic acid labeling contraindicates use with combined hormonal contraceptives.
用白話說明這項交互作用的意義
Ethinylestradiol 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.
為什麼會發生
Additive prothrombotic effects of fibrinolysis inhibition and estrogen-induced increases in clotting factors.
處置方式
Avoid the combination; use non-hormonal or progestin-only contraception while taking tranexamic acid, or choose another heavy-bleeding treatment.
