Factor Xa inhibitor (blood thinner)

SAVAYSA (edoxaban) is a prescription medicine used to lower the risk of stroke and blood clots in people with certain heart conditions. It is also used to treat blood clots in the legs (deep vein thrombosis) or lungs (pulmonary embolism). Because it thins the blood, it can increase your risk of serious bleeding.

How it worksSAVAYSA works by blocking a specific protein in your body called Factor Xa. This protein is necessary for blood clotting, so by blocking it, the medicine helps prevent dangerous blood clots from forming.

BreastfeedingDo not breastfeed while taking SAVAYSA because it may cause serious bleeding in nursing infants.

PediatricThe safety and effectiveness of SAVAYSA have not been established for children.

GeriatricStudies show that the safety and effectiveness of SAVAYSA in elderly patients (65 and older) are similar to those seen in younger patients.

Talk to your doctor
