Coumadin Overview

Warfarin (also known by the brand names Coumadin, Jantoven, Marevan, Uniwarfin) is an anticoagulant normally used in the prevention of thrombosis and thromboembolism, the formation of blood clots in the blood vessels and their migration elsewhere in the body, respectively. It was initially introduced in 1948 as a pesticide against rats and mice, and is still used for this purpose, although more potent poisons such as brodifacoum have since been developed. In the early 1950s, warfarin was foun...

Coumadin (drug) vs Nattokinese (natural)
9 Replies RSS
COUMADIN (actually a rat poison!) is a commonly used blood thinner with some bad side effects. NATTOKINESE is a natural blood thinner with hardly ANY side effects. Any problem switching from coumadin to nattokinese? if YES how (gradually, or...) if NOT why not ? Mike ## How do I switch from COUMADIN (taking now 7mg due to an arterial blood clot, chronic arrythmya, and a small coronary artery) to natural NATTOKINESE? Has anyone done it and can I myself do it - SAFELY.My doctors are absolutelly oposing it!! Thank you for help. Mike, Toronto, Canada ## I am having hip surgery next week. The doctor insists on my taking 2.5 mg of Coumadin for 30 days to prevent blood clots. I would prefer a natural blood thinner, i.e. Vitamin K. I have no history of heart or stroke, am in exdcellent health ,...

My Father Died from Coumadin
7 Replies RSS
My father was on Coumadin. One day he hit his head. If it were not for Coumadin, the small bump on his head would have amounted to nothing unusual. However, the Coumadin resulted in a cerebral hemorraghe. Even though he had been takikng Coumadin exactly as prescribed and had gone for each of his INR checks, when he got to the hospital, the doctors found his INR was off the richter scale. To relieve the pressure on his brain from the hemorraghe, they needed to operate. But they couldn't because his INR level was too high. They said it would take 24 hours to reduce his INR to a level at which they could operate. By that time, he was dead. Subsequently, the doctors wanted to put me on Coumadin for a year. I said no. They insisted and finally said you have to go on Coumadin for at least...

RSD and Itching - 80 on one side and other
Post a Reply
Hi, I have had Avascular Necrosis, and Reflex Sympathetic Dystrophy (stage 4). I have implanted Pain pump that infuses the medication directly into the Spinal Fluid. Over the past several years, I developed extremely "violent" itching. This itching leads to bruising in very large areas. I am also on Coumadin, currently 3mgs a day. I had two bouts with BiPulmonary Embolism(s) back in 1995-1996. I have been prescribed Atarax, Benedryl, and Allegra; all for this itching. I have used virtually OTC cream, spray, and additional Benedryl when I "flare up. This itch is driving me NUTS, and has gone through the same frustration of everything NOT working. I do have a "laundry list" of Meds, as well, other Medical problems that were diagnosed after my knee surgery. I need someo...

Which brings me to my next point, if they aren't even sure that you had a...

Warfarin (Coumadin) and PT-INR levels
6 Replies RSS
I am 19 years old and have had 4 blood clots so far due to a birth control pill. I have to go every week and get my INR levels checked. Right now I am taking 4 mg on even days and 5 mg on odd days. My levels go from 1.7 to 4.4 to 3.8 to 2.4. I really dont like going every week to get my finger poked, especially at my age. Is there a recommendation that anyone can give me, like a different blood thinner, that I can talk to my doctor about? Or just any advice will help. Thanks ## Hi Julie, I'm sorry to hear about your situation, that sounds rough. I don't have any experience with blood thinners so unfortunately I can't recommend any new ones to you, but according to live, there are foods that act as natural blood thinners. Maybe you incorporate some of these foods i...

if i m on coumadin should be taking percocet or is oxycodone better to take
1 Reply RSS
i'm on coumadin for blood clots and recently had surgery they put me on oxycodone 10 mg.tabs for pain and know switched me to percocet which contains acetaminophen should i be concerned? i guess what i'm asking is which is better to take with warfin? ## John, I take Warfarin and haven't been able to add or subtract anything without doing a series of the INR so that the Warfarin could be adjusted if needed. Is the doctor who prescribed the pain medication, the same doctor who put you on Warfarin? If not, I would call the doctor who is treating the blood clots to see if you need to check (INR) or what. Even Alka Selzer can effect how thin your blood is.

coumadin and secere headaches

i am TAKING COUMADIN for one time small DVT and have had SEVERE HEADACHES! my doctor only cares about that INR Levels; as pain is not important to him! As an experiment; I stopped the coumadin for one day and ZERO HEADACHE...when i resumed the came right back!!! any one else suffering with this unwanted side effect? ## Hello, Sara! How are you? Headaches can be a side effect of Coumadin. How long have you been taking it? Usually, such side effects will taper off after about 4 to 6 weeks, once your body gets used to the medication. And honestly, if your doctor isn't listening to you, then it might be time to consult a different doctor that's going to pay attention. Are there any other questions or concerns? ## thank u for your input. i actually have been 'clear...

I am an athlete and I was diagnosed with a DVT a year ago, after waiting 5 hours at the emergency with a broken arm. I took coumadin for 3months, 5mg, the same year. Now I still train and I am very active. However, my blood pressure raised quickly and severely in the past months. My doctor doesn't know the cause. I talked with the specialist who gave the prescription of coumadin and he told me that it's possible due to the use of the medication. He told me that some people end up with high blood pressure and some with other complications. THIS MEDICATION IS EXTREMELY DANGEROUS! TRY TO AVOID IT! IT'S POISON... Opt for other medications. ## Thanks for the heads up on this medication. There seem to be many discussion threads here relating to the issues people were having with i...
