<unk>  is a disorder of the embryo which occurs in a child whose mother took the medication<unk>  (brand name: Coumadin) during pregnancy. Resulting abnormalities include low birth weight, slower growth, mental retardation, deafness, small head size, and malformed bones, cartilage, and joints.<unk>  is an oral anticoagulant drug (blood thinner) used to reduce blood clots, deep vein thrombosis, and embolism in people with prosthetic heart valves, atrial fibrillation, or those who have suffered ischemic stroke.<unk>  blocks the action of vitamin K, causing an inhibition of blood clotting factors and the pro-bone-building hormone osteocalcin.<unk>  is a teratogen which can cross from the mother to the developing fetus. The inhibition of clotting factors can lead to internal bleeding of the fetus while the inhibition of osteocalcin causes lower bone growth. As well as birth defects,<unk>  can induce spontaneous abortion or stillbirth. Because of this,<unk>  is contraindicated during pregnancy.
