SN instructed patient how Lovenox is used to reduce the chance of blood clots when another blood thinner is held for a short time. When you take an oral blood thinner and need a procedure/surgery, your doctor asks you to temporarily stop taking your usual blood thinner and instead take enoxaparin to help prevent blood clots before the procedure/surgery. After the procedure/surgery, your doctor will tell you when it is safe to start taking your regularly prescribed oral blood thinner again. This is called bridge therapy it allows for continued blood thinning without the blood being too thin for too long as oral blood thinners stay in the body for a much longer time.
