Generic Name: tranexamic acid (TRAN-ex-AM-ik AS-id)
Brand Name: Lysteda
Tranexamic acid is used for:
Treating heavy menstrual bleeding.
Tranexamic acid is an antifibrinolytic. It works by preventing blood clots from breaking down too quickly. This helps to reduce excessive bleeding.
Do NOT use tranexamic acid if:
- you are allergic to any ingredient in tranexamic acid
- you have blood clots (eg, in the leg, lung, eye, brain), a history of blood clots, or conditions that may increase your risk of blood clots (eg, certain heart valve problems, certain types of irregular heartbeat, certain blood clotting problems)
- you have bleeding in the brain, blood in the urine, or bleeding related to kidney problems
- you have a disturbance of color vision
- you have irregular menstrual bleeding of unknown cause
- you are using medicine to help your blood clot (eg, factor IX complex concentrates or anti-inhibitor coagulant concentrates)
Contact your doctor or health care provider right away if any of these apply to you.
