What is the most important information I should know about Lysteda?
You should not use this medication 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 this medicine, 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.
Do not take more than 6 tablets in one 24-hour period.
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.
