Anticoagulants are blood thinning agents that decrease the blood's ability to form clots.
They do not dissolve already-formed clots, but they can keep the clot from getting larger. Anticoagulants are used to treat certain heart, lung, and blood vessel conditions. Do not make any major dietary changes without consulting the health care provider who prescribed the anticoagulant. Be careful not to injure or cut oneself, as bleeding may be prolonged. Vitamin K has an important effect on anticoagulant therapy.
