Why is my blood still too thick after my dr upping my Coumadin (warfarin) from 2.5 mg to 10 mg?

Why is my blood still too thick after my dr upping my Coumadin (warfarin) from 2.5 mg to 10 mg?

Other issues: First, no such thing as "thick" or "thin" blood. If you need to have blood that does not make clots easily, we give Coumadin (warfarin) because it is "defective vitamin k". Your liver tries to use the Coumadin (warfarin) to make things necessary to make clots. Since the liver is getting defective vitamin k, it makes less things to make clots. If you eat a lot of k. Or have some other cause for clots, Coumadin (warfarin) fails. ...Read more

Is xarelta as effective in treating blood clots as warfarin?

Is xarelta as effective in treating blood clots as warfarin?

Xarelto: Yes. Xarelto (rivaroxaban) is equally effective as coumadin (warfarin). Initially it was given only for irregular heart beat atrial fibrillation. Now the use is expanded to leg clot DVT and lung clot pe. The advantage of xarelto over Coumadin is that there is no periodic blood checkup for pt/ inr just like coumadin. It can be expensive & inconvenient. Can't monitor level & no antidote. ...Read more

I am on warfarin. What blood thinning foods should I avoid? I know vit k thickens the blood. Was never told what thinning foods to avoid.

I am on warfarin. What blood thinning foods should I avoid? I know vit k thickens the blood. Was never told what thinning foods to avoid.

Take Vit K with Warf: I'm not a fan of warfarin because nearly every food, drug ; herb affects it, making its effects very variable. It's not that vit k "thickens blood"- it's needed for blood to clot; warfarin works by inhibiting it, but blocking vit k increases risk of cardiovascular disease, osteoporosis ; maybe cancer- better to take some k ; adjust warfarin dose accordingly- this improves outcomes! See comment:. ...Read more

I know the normal range for Des Gamma Carboxy (DCP) blood count is up to 7.5. If I am taking warfarin what would be considered a "normal" range?

Almost never used: I have been a hematologist for 30 years, and I have never ordered this test. Warfarin is dosed according to the widely available prothrombin time test. All the guiding clinical trials are based on that measurement. ...Read more

I am currently on warfarin for a blood clot disorder. Anyone know about umbrellas?

I am currently on warfarin for a blood clot disorder. Anyone know about umbrellas?

Yes: By umbrellas, I assume you mean a vena caval filter. This is an umbrella shaped device placed into the inferior vena cava to catch any clots from the legs that may break and potentially go to the lungs. These devices are not for all patients with DVT or pe. They have their own potential complications. Usually they are reserved for people with blood clots in the legs/lungs who cannot take coumadin (warfarin). ...Read more

I'm on Coumadin (warfarin) and everyweek I loose blood could this make me dhydrated if so what do I drink?

I'm on Coumadin (warfarin) and everyweek I loose blood could this make me dhydrated if so what do I drink?

Just liquids: Coumadin (warfarin) is a blood thinner, it reduces clotting: how are you losing blood? Only trauma (a cut, bruise etc) would allow the effects of Coumadin (warfarin) to reduce blood volume. Your dosage may need to changed. Speak to an md, especially a hematologist. Hydration has no effect on how the medication works, other than it is healthy to stay hydrated. ...Read more

Can I take Coumadin (warfarin) with simvastatin? I read where it thins the blood so could be dangerous. Thanks.

Can I take Coumadin (warfarin) with simvastatin? I read where it thins the blood so could be dangerous. Thanks.

Drug interaction: When you take more than one drug you do have an interaction. Simvastatin and coumadin (warfarin) are very often given together. Though now with newer blood thinners less coumadin (warfarin) is being used. Studies have shown that some statins increase risk and some decrease risk of bleeding. So if you have no increased signs of bruising and bleeding you may be still okay. ...Read more

What do you advise if I'm currently on warfarin for a blood clot disorder. Anyone know about the progress on replacements?

Novel anticoagulants: There have been 3 "warfarin substitutes" since 2010 that have FDA approval for venous thromboembolism prevention, treatment of venous thromboembolism, or stroke prevention in atrial fibrillation. They include the oral direct thrombin inhibitor dabigatran, and the oral direct factor Xa inhibitors rivaroxaban and apixaban. All agents have predictable pharmacokinetic profiles and do not require monitoring ...Read more

So Coumadin (warfarin) thins the blood to prevent new clots from forming --is there anything in Coumadin (warfarin) to actively dissolve clot that are already formed or are?

So Coumadin (warfarin) thins the blood to prevent new clots from forming --is there anything in Coumadin (warfarin) to actively dissolve clot that are already formed or are?

No: Coumadin (warfarin) keeps more clots from forming and thus facilitates the working of the body's clot breakdown system. Nothing in Coumadin (warfarin) actively breaks down clot...Only fibrinolytic agents like tpa do this and are given intraarterially or intravenously. ...Read more

Blood thickened even though food/lifestyle was unchanged (inr dropped to 1.3). Upping warfarin 3mg to 7mg did nothing. Now on 9mg and also daily heparin injections. Inr still 1.3. Why no improvement

Blood thickened even though food/lifestyle was unchanged (inr dropped to 1.3). Upping warfarin 3mg to 7mg did nothing. Now on 9mg and also daily heparin injections. Inr still 1.3. Why no improvement

Coumadin (warfarin) resistance: 95% of people get adequate response to Coumadin (warfarin) with dosage between 1-9mg. Thus leaving about 5% of people need above 9mg--because of several posible causes: poor absorption (drug such as Cholestyramine can cause this), too rapid elimination, xcessivevit k intake, hyperlipidemia, certain drugs, or hereditary resistance (rare), and at times unknown. Consult doc for adjustment. Good luck. ...Read more

Does warfarin blood thinner block k1 and k2 vitamins? M

Does warfarin blood thinner block k1 and k2 vitamins? M

Vitamin K antagonist: In medical school, we memorized clotting cascade. Warfarin works by blocking (formation of) vitamin K dependent factors (http://goo. Gl/LP1DwM). Therefore, the more vitamin K rich foods eg dark leafy greens that you consume, the greater the dose of warfarin that you'll need. That's why it's also important to eat same am't daily (or none at all) to keep blood thinness just right (as measured by INR) ...Read more

Can I have cataract surgery if I am using blood thinners like Coumadin (warfarin) for another condition?

Yes: Most cataract surgery is performed through the cornea which does not have blood vessels. This means that there is no bleeding. The cataract itself also does not have blood vessels. It has been studied and found that stopping blood thinners before cataract surgery is much more dangerous than having the surgery on them. ...Read more
