Lysteda (tranexamic acid) is a man-made form of an amino acid (protein) called lysine. Tranexamic acid prevents enzymes in the body from breaking down blood clots.
Lysteda is used to treat heavy menstrual bleeding. This medication will not treat premenstrual syndrome (PMS).
Lysteda may also be used for purposes not listed in this medication guide.
Important information
You should not use Lysteda if you are allergic to tranexamic acid, if you have problems with the blood vessels in your eyes, or if you have ever had a stroke, blood clot, or bleeding in your brain.
Before using Lysteda, tell your doctor if you have kidney disease, leukemia, a history of endometriosis, or if your menstrual cycles are less than 21 days apart or longer than 35 days apart.
Do not start taking Lysteda until your period has started. Do not take it for longer than 5 days in a row. Talk with your doctor if your symptoms do not improve after 2 cycles of treatment.

Use a barrier form of birth control (such as a condom or diaphragm with spermicide). Hormonal contraception (such as birth control pills, injections, implants, skin patches, and vaginal rings) may increase your risk of stroke, blood clot, or heart attack if they are used at the same time as Lysteda. Do not share Lysteda with another person, even if they have the same symptoms you have.
