Long Term Effects of Warfarin

Ok, I have APS & am obviously on life long warfarin. Recently gone in2 a lupus flare which has so far lasted 2 years, nervous system involvement this time & wondering if it has anything 2 do with long term warfarin use. First heard rumours about long term warfarin use about 3 years ago, which my Rheumy & Haemo both deny but these rumours keep coming up & some1 else has mentioned them 2night. Like they say there's no smoke without fire :0/ Any1 else know anything about this?

  • I have been on Warfarin since 1982 and have no long term effects except that I am still alive.I was self managing.

  • what is your average daily dosage and INR for the 30 year span?

  • 5mg and 2.5 although it can be whatever I want as I am self managing using the Coaguchek. 2.5 seems to work for me although I received different views on my ideal INR from my heart surgeon, who like 2.0 to 2.5 and my GP who goes by the book at 2.5 to 3.5. At 2.5 I do not seem to have general bruising problems.

  • I have often wondered about this - and worried! Thanks armitaged, you have just put my mind at rest. I think we need to hear more positive stories about Warfarin use, there always seems to be a lot of negative ones.

  • Until recently, warfarin was considered suitable for most patients but has a high risk of bleeding if your INR is above your therapeutic range and the Gold Standard is 60% of time in range. Why not ask your provider what percentage is your INR in range?

    Now the question is whether being on long term warfarin has a long term effect. When Coumadin is taken it creates a vitamin K deficiency and the liver responds by channeling available vitamin K to clotting protein function, at the expense of other vitamin K dependent proteins. Why not look it up!

    It's my opinion that if warfarin is that good for you, why are companies developing new anticoagulants that does not react to food and most drugs. However, the new anticoagulants still creates through the liver.

    For me, it's going to be the new anticoagulant Rivaroxaban.

  • thanks 4 all the replies. There's no argument about it's ability 2 do it's job & having been on it 4 over 18 years, I know I wouldn't b here if it didn't exist. My INR has always been stable & not worried about the effect on bones etc as there r things we can do 2 help guard against that & in all honesty, every med we take comes with side effects. I just wondered if any other long term user had noticed any central nervous system/neurological effects. Just seems a little coincidental that when on clexane some of my problems disappear :0/ Maybe I'm just odd lol!

  • I don't think you are odd in the slightest, being concerned about your long term health is anything but odd. The problem that we all face is separating the correlation from the causation, this requires a lot of unbiased hard work and generally takes years after which a new set of evidence can always overturn the original verdict. Difficult.

    Good luck to you.

  • I think that we would all be wise to be concerned about the long term effects of any medication so this is a good question to raise. I can offer no clinical answers but simply relate that my mother was on warfarin for 25 years until she died at age 82 after pneumonia following a fall and fractured Femur. I have been on Warfarin for 14 years and am now 66. Neither my mother nor I have ever been aware of any side effects arising directly or indirectly from Warfarin and have had no experiences of the symptoms you have referred to. It has all been good news. In my case I have self managed for most of the time I have been on Warfarin and my mother was entirely managed by medical professionals. I wonder if you take any other medication as well as Warfarin? This can lead to complications in some cases and even taking Statins can affect the potency of Warfarin in raising the INR.

  • Don't take any other meds (except 4 pain relief) as nothing prescribed was worth the added hassle of the side effects. Cheers 4 the reply :0)
