Marivanil is used to prevent and treat deep vein thrombosis, a condition that occurs when a clot forms in the deep veins, especially in the legs. It is also used to prevent pulmonary artery obstruction resulting from the movement of blood clots to the lungs. It is commonly prescribed to patients with nonvalvular atrial fibrillation, a condition that causes an irregular heart rhythm that increases the risk of clots. Marivanil treats patients who have undergone surgery to install an artificial heart valve and may need to take
Marivanil regularly to reduce the risk of clotting in the valve. It is also used to prevent recurrence of clots in patients who have previously suffered strokes or heart attacks.
