5 MG Eliquis is a medication classified as a blood thinner or anticoagulant. Blood clots are both treated and prevented by it. This both prevents and treats the development of clots in the heart, lungs, brain, and legs veins. It is used to lower the risk of heart attack and stroke. The medicine is frequently used to prevent clot formation in people with abnormal cardiac rhythms (atrial fibrillation). Also, 5 MG Eliquis lowers the chance of blood clots forming in patients who have had knee or hip replacement procedures.
