Common Questions and Answers about Warfarin dosing based on inr

Dear Sir, Kindly advise as to what precautions my father should take for his INR fluctuation as he is daily taking WARF 5mg.
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.
37 for placebo (10). In a study of 11 patients on stable warfarin, INR increased after 4 days of taking APAP 4 g/day increasing the risk of bleeding (7). A 72-year-old man was on acenocoumarol, chronically self-medicating with APAP 1 to 2 g/day for low back pain. His INR was stable at 2.5, 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).
Based on my own personal experience I would avoid the Tikosyn and the Flecainide based on experiences that I have had, however everyone responds differently and its important that you and your doctor maintain dialog about what works and what does not work for you. I have been in Afib for 3 years straight now and I have also been on Warfarin for that same period of time.
Everyone is different regarding dose and doseage should based on a blood test called the INR (International Normalized Ratio). The amount of medication you take may change, based on the blood test.
Plavix is recommended for up to 1 year after stent implants to prevent blood clots for the DESs that have a higher record to clot. Aspirin is recommended indefinitely and there is a different pharmological pathway between the two anticoangulants.
A person on warfarin with an inr of 1.2 is not at risk of bleeding out. They are at risk for a clot. People not on warfarin normal range of about 1 because they don't have a bleeding or clotting disorder, thus 1 is normal.
I take 10 MG a day everyday and my inr was 2.2 just today. It all depends o. The reason behind taking it.
As someone who is on warfarin, I have the same impresson of an INR of 4.8 as you do -- that it is undesirable but not greatly alarming. I have never heard that the INR is interpreted any differently for an infant than for an older person. There are some "heart mom" forums on the internet for mothers of children with congenital heart disease. I don't know where to direct you, but if you can find a forum such as that, this is a question that some of the other moms might know.
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.
s body can metabolize and excrete the warfarin. That is why doctors typically give someone who is on warfarin a prescribed INR range, rather than a set dosage of warfarin, because the dose will differ from person to person.
Whatever the amount of warfarin is that you personally need -- and yes, you are your own person and not a textbook person -- for your INR to be within your prescribed range is the amount that YOU need.
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 am a 71y male, active , working medical professional, with Hx of Htn & carbamatic mechanical aortic valve in 2000 for AI. Non Eluding Stent in Nov. 2009. Although published INR range is b/w 2-3 for patients on triple anti-thrombotic therapy of 75mg clopidogrel, 80mg asprin & warfarin,I've also heard that INR of 1.5 - 2 is also acceptable. Kindly verify, confirm, advise, forward relevant studies/trials PDFs.Thank you for your timely response and effort.
