I've been on Warfarin since 1993 and it does make you feel cold all the time and it has made me feel weaker too and I,m 35 years old and on 6mg's a day, I have even been up to 10mg's a day.When my blood gets to thin I get little (like niddle holes) red dots, and my head hurts but if it gets to thick my head hurts too.Can you tell when your blood is to thin or thick?And haw do you feel on the Warfarin?

I have been on warfarin since 1994 and do my own blood testing when my blood is to thin i feel very light headed and bruises appear when it is to thick i get a kick in the legs its like a flick from inside and makes you feel like a slight jolt.I find that being on furosemide does badly affect your warfarin and had to reduce my dose

yes, you get cold very easy on warfrain. bouncybouncy in answering your question asked how you feel when it is low or high. If you will watch everything you eat, not lots of vit k foods, your INR will stay close to 2-3. Keep regular checks with your doctor. I have been on warfrain 5 months and can't really tell that I am on warfrain. I work everyday, although I get tired and learn to rest. Take a good multi vit and mineral that doesn't have vit k.

I take 12.5mg/day... and I shiver a lot. Yes, that is one of the side effects.

Thanks for all the comments re freezing while on warafrin. I was cold natured before I started warafrin approximately 5 months ago, now I literally freeze all the time. The cold seems to be from within... not too cold to the touch

Hi everyone!! I have Factor V Leiden, a clotting disorder that makes the blood HYPER coaguable. I get so cold sometimes, even in a warm room.
The warfarin, depending on your
daily dose, as well as your PTT and
INR results, can certainly affect
how your body reacts to the cold or
its sensation of cold. As your blood
gets thinner... I.e., your INR number
is higher ( than perhaps the
therapeutic level set by your
physician... which is typically
between 2.0 to 3.0), your reaction to
even a slight breeze is heightened
because your blood is thinner. I
hope this answer helps. Have a
wonderful day!!

I do get chills and my feet and hands get cold. and I get very hot most of the time, my face gets real hot, I feel like I am going through the change again, I also have headaches about every day. I am 75 and started on warfarin almost a year now. I take five mg. sometimes a half pill. I have had my second blood clot in my other leg. I am getting around good right now.. free discount card
