Warfarin can cause birth defects, but preventing blood clots may outweigh any risks to the baby.
Warfarin is used primarily as a blood thinner to prevent the formation of blood clots.
Drugs that compete as substrates for these cytochromes or inhibit their activity may increase warfarin plasma concentrations and INR, potentially increasing the risk of bleeding.
Blood clots can also occur in the atria of the heart during atrial fibrillation and around artificial heart valves. In addition, the INR may be assessed when initiating, discontinuing, or changing doses of medications that are known to interact with warfarin. Use this medication regularly to get the most benefit from it.
Vitamin K - Eating an increased amount of foods rich in vitamin K can lower the PT and INR, making warfarin less effective and potentially increasing the risk of blood clots. The goal of warfarin therapy is to decrease the clotting tendency of blood, not to prevent clotting completely.
