Does taking coumadin REALLY make you feel cold? With no change in body temp?

26 Jun 2010

Hello Latricia1, I have been on Coumadin for 8+ years and will be on it for life. I have been told by a Hematologist (blood specialist) that once in a great while that can be expected, unfortunately there is no specific tests that have been run for that to verify it. I have on occassion have gotten cold sometimes when my levels were too high, and they keep them high as it is because of my blood clotting disorder, but not very frequently. This may be an individual reaction for your dad. I suggest keeping a record of how he is feeling for about a week to 10 days and then asking his doctor about it. But I don't think it is anything to get too worried about at this point. I wish you and your dad the best of luck with the Coumadin it can be a tricky drug sometimes. marjorie zych

Marjorie is absolutely right. I have been on blood thinners for 6 years.
Being cooled is from your blood being thinner, like when people from Florida come here in the spring when the temperature is 65 and they freeze when we think it nice out. People who live in warmer climates have thinner blood because they live were it's warmer.warmer.Coumadin thins the blood out.
Sometimes I freezing when my wife is comfortable. It's just the Coumadan. Also like she said becareful that your INR "blood level" is not to thin. You may want to get it checked at Dr. offices.

I agree with the other 2 individuals. It needs to be because the blood is thinner. I have been on coumadin for a little over a month and will be for life and I am always uncomfortably cold when everyone else is warm. I have two pairs of socks and warm winter boots on with 2 blankets all the time to take the edge off, the nurse told "you will get used to it" :(

Hello - I was 33 when I began coumadin in 2005 due to having a mechanical heart valve. I immediately noticed I am a little more sensitive to cold weather and cold things (ice, frozen food, etc.) It's not terribly bothersome, however. But yes, in my case, I seem to get colder than I used to!

Coumadin is an anticoagulant that changes the clotting factors in the blood so as to prevent clotting. It does not "water-down" or physically "thin" the blood. That is an misnomer.

I firmly believe Coumadin can make you feel cold. I have been on it for nearly 8 years. When my level gets above 4.0 I tend to have chills even though I have no temperature. The temperature inside my home or outside does not affect it.
