Corparin 40 is often used to treat thrombosis and prevent further clots, including after a stroke or infarct. It can help reduce the risk of clot extension and new clots in your cerebellum. However, the exact dose, duration, and monitoring need to be determined by your doctor, and it must be given under medical supervision because of the risk of bleeding. Follow your doctor's instructions closely and report any unusual bruising, bleeding, or headaches immediately.
