My Dad who is 77 has been on Coumadin since 2005 after a DVT following surgery, He also has Afib and has had it for years, due to a thyroid condition. he also has a pacemaker. He's been on Armour thyroid for at least 4 years, and tried Armour instead of Synthoid to see if he would feel better on Synthoid's alternative. Which he does actually feel better emotionally on the Armour.
hi st142 , I assume DVR stands for "Double Valve Replacement"; the fact that you are on Warfarin and monitoring your PT/INR indicates that you are on therapy to prevent embolism from a mechanical/bio-prosthetic valve in the heart.
While you are on Warfarin - and this would be life-long for you - you are at risk from both under-dosing, which would lead to embolism, and over-dosing, when you could have bleeding from some part of your body, including the brain.
5, but when APAP was stopped his INR dropped to 1.62. Two weeks later, he restarted APAP and the INR climbed to 2.0 over 4 weeks (5). A 77-year-old woman who developed a 2-fold increase in INR while receiving APAP with concomitant acenocoumarol (8), and a 74-year-old man experienced a 3-fold increase in INR when APAP was added to his stable warfarin regimen (6). Fluindione has also been implicated in this interaction (9).
A drastic change in diet can alter INR also, but in my own personal experience, it has usually been other meds that caused me to need to change my warfarin dosage and not my diet. An INR that is consistently out of range is dangerous. Don't worry about maintaining the same dose of warfarin. Worry about maintaining an INR that is consistently within range. Whatever dose of warfarin you have to take to stay in range is okay.

My son has been on warfarin since he was 7 weeks old due to having a mechanical Mitral valve replacement. His INR today is 4.8. The highest it's ever been.He is six months now and just starting solids which may be why the INR has been all over the place. I have been instructed to withhold his dose tonight and I'll test him again tomorrow. I've been doing some reading that INR of 4.8 is undesirable but not overly dangerous. Is that the case for babies as well?
I take Warfarin as follows: 3mg 2xda for 2 da and 4mg 2xda rest of week. Can't seem to get my levels even. Is the dosage too little or not enough?
Until 2 months back I was taking 150mg Ecosprin and 5mg Warfarin daily, then I was diagnosed with Hepatitis E and my INR value increased suddenly, so my doctor cut on the warfarin for few days until it dropped to <1.5 and then I started taking my warfarin again but my INR didn't increase. 2 weeks back my doctor increased my dose from 5 to 6mg but still my INR value is 1.4 and it is not increasing from past 2 months.
Please help.
You have a lot going on in your body that could make you feel bad, beside taking warfarin, and the warfarin is probably the least likely culprit.
The amount of warfarin that any given individual has to take to stay within an INR range of 2.0 to 3.0 (which is probably what the doctors mean when they tell you they want you at 2.5) will vary, depending on how rapidly that person's body can metabolize and excrete the warfarin.
I was on warfarin for 6 months and a dvt in the popliteal vein. when my inr went up due to being on anti inflammotories- I had severe neck pain and nothing else helped- my inr nurse told me to increase my vitamin k veggies and this worked well to keep it even. When it went down my dose was increased and or I was told to skip green veggies that day and take an extra dose. I went for testing nearly every week during the time I was on warfarin due to lots of fluctuations.
I test my own blood and adjust my dosage of warfarin. Usually I'm right in range 2.5 to 3.5 (2 art heart valves). About 6 to 8 weeks ago, I took augmentin for 10 days, 2 weeks ago, I took another antibiotic for 5 days. Since then, my PT/INR has been too low, 2.0. My diet and meds have stayed the same. I've been increasing my dose, yet it's still too low. Is it normal for this change? Please see my profile! Can it indicate my lupus activity?
I'm not a doctor, just a patient who has been on warfarin for the past eight years. I had a mechanical heart valve implanted in 2004. I'm medically literate, and I've tried to read as much as I can about warfarin along the way. I even went to a day-long CEU workshop for medical professionals on warfarin management and got the certificate. But I'm still not an expert.
I am 53 and just had my 2nd open heart surgery 2 months ago. 3 years ago a bovine aortic valve was put in and there was major scarring that occured. So in December they replaced it with a mechanical valve. I'm now on Warfarin 7.5 and have been maintaining an INR of 2.5-2.8. Last week I had a severe stomach virus and became very dehydrated. I went in for my draw yesterday and recieved a call last night from my cardiologist.
