Marevan is used to treat and prevent blood clots in the body. This medicine is prescribed for patients who suffer from blood disorders that increase the likelihood of clots, such as atrial fibrillation or deep vein thrombosis. Marevan is also used as part of preventive treatment to prevent recurrent blood clots or blockages in the arteries that may cause serious complications such as stroke or heart attack. This medicine works by reducing the blood's ability to clot by inhibiting the mechanism of producing some important clotting factors in the body.
Marevan is often prescribed for patients after undergoing certain surgeries such as heart valve replacement, as they have an increased chance of developing serious clots.
