Coumadin and altitude

[GOOGLEFREETEXTUNIQ-5-7vitamin cottage natural grocers albuquerque]

I have a titanium aortic valve. I sometimes experience atrial fibrillation afib. I take 5 mg daily of warfarin. One day per week I take 7. I also take a baby aspirin 81 mg daily as per the cardiologist. Today my PT was 2, coumadin and altitude. I am aware of most of the foods high in vitamin K and try to use them sparingly and consistently. I live at sea level. I will be up aroundfeet for a week! What will happen to the value upon return home? I also consume alcohol in the form of beer and wine.

I sometimes consume more when on vacation. The last time we went to Colorado, we were there for one week and did consume beer at the various breweries. When I came home, I was working in the yard and developed a hematoma on my wrist.

Any advice for my next trip? Here is my answer to the inquirer: Hello and thank you for your question. Alcohol is a more likely culprit. Chronic long-term alcohol consumption at a level that can damage the liver is a known cause of bleeding, as liver damage reduces the production of the coagulation factors. Consequently, there is really no firm answer to your question, coumadin and altitude.

Please respond here if you have seen this. May 16, 7: Aug 15, I normally live on the Pacific coast of Mexico, and take 2 mg of acenocumarol a warfarin nightly. This keeps my INR between 2. I have a titanium aortal valve. When I visit my other home, in San Miguel de Allende, at ft. I therefore increase my nightly dose to 3 mgs, which puts my INR back in the correct range. If, however I continue the 3 mg dose while at the beach, my INR goes to over 5, so I reduce the dose again to 2 mg.

Aug 18, This again raises the possibility that the INR is affected by altitude, however it is more likely that interlaboratory variation is the culprit, despite the claim that the INR should be the same everywhere. Rather than adjusting your dosage, you may wish to try different laboratories in either location.

Aug 22, coumadin and altitude, I have done so, coumadin and altitude. Since I was originally operated on at over ft and dosed with acenocumarol for several weeks before returning to sea anti-inflammatory drugs and high blood pressure, I was forced to lower the dose while at the beach.

Both labs, the most reputable in either area, assure me that they use the same reagent, but that the control groups could be different, thus causing the difference.

Coumadin and altitude offer this info only coumadin and altitude a report of my experience, not as a recommendation. Aug 22, 7: This is interesting and raises the question of altitude and the INR again. Given the consistency coumadin and altitude time, it would be worth studying further.
