I have been told that I have a blood clot in my leg and have been given warfarin. How long should I remain on this medicine?

If you have blood clots in your legs, you need to be on a blood thinner –which is warfarin. It is sold as Coumadin and is an excellent drug for people with blood clots. If blood clots are not treated, they may break off and fly off to the lung. In most cases of a first time blood clot in the leg, you need to take the medication for at least 6 -9 months.
