Is warfarin a blood thinner?

Is warfarin a blood thinner?

Yes: Coumadin (warfarin) is routinely used as a chronic blood thinner. It works by inhibiting several coagulation factors (factors ii, vii, ix, and x) as well as anticoagulating factors (proteins c and s). Patients are typically "bridged" to Coumadin with another blood thinner like heparin. ...Read more

Blood Thinners (Definition)

Agents which slow ;/or break down blood clot formation in up to 3 different ways (they do not decrease blood viscosity; thickness.) (1) some inhibit platelet function (e.g. Aspirin, clopidogrel, etc.). (2) others interfere with some of the clot forming proteins (warfarin, dabigatran, rivaroxaban, etc.), (3) others stimulate the blood clot destruction ...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

While taking warfarin blood thinner is it ok to continue drinking aloe era juice?

While taking warfarin blood thinner is it ok to continue drinking aloe era juice?

Not simple: Aloe juice has no legitimate, documented health benefit. If you drink it simply because you love the taste, then keep the amount constant every day. It may prolong the prothrombin time in a dose- dependent manner. The dose of coumidin will then be adjusted downward after your blood tests. ...Read more

Does prune juice have enough vitamin K to affect my warfarin blood thinner?

Does prune juice have enough vitamin K to affect my warfarin blood thinner?

Prune juice: Vitamin K, how much prune juice are you drinking? It would take a lot to alter your INR. One cup has a bit less than 10mcg, that's not much if that's all you are ingesting. ...Read more

Can I get a tattoo after a mechanical mitral valve replacement and now on Coumadin (warfarin) (blood thinners)?

Can I get a tattoo after a mechanical mitral valve replacement and now on Coumadin (warfarin) (blood thinners)?

No: You should be on antibiotics in advance to minimize chance of infection. You also are going to bleed because of the coumadin (warfarin). I doubt your cardiologist will stop Coumadin (warfarin) for a tattoo.If you decide to do this there may be bleeding in the skin which will affect the appearance of the tattoo. ...Read more

Does Coumadin (warfarin) make you extremely fatigued? Is there a medication that is a blood thinner but you don't need an INR check?

Rivaroxaban.: Coumadin (warfarin) does not make you extremely fatigued unless you're anemic from occult bleeding because of a supratherapeutic (i.e., really high) inr. Make sure you stay on top of your inr and, if you're feeling really fatigued, to have your hemoglobin/hematocrit (which is your blood count) checked. Rivaroxaban is a blood thinner that doesn't require monitoring. Discuss with your pcp. ...Read more

I have fibromyalgia , chronic migraines & mechanical bicuspid valve replacement and am on coumadin (warfarin). Will pot affect my valve or make blood thinner?

I have fibromyalgia , chronic migraines & mechanical bicuspid valve replacement and am on coumadin (warfarin). Will pot affect my valve or make blood thinner?

YES: Discussion: marijuana may increase warfarin anticoagulant effect by inhibiting its metabolism, and to a lesser extent, displacing warfarin from protein-binding sites. Other causes (eg, nonadherence) of the patient's increased inr were ruled out. Using the horn drug interaction probability scale, our patient's warfarin/marijuana interaction appeared to be probable.Ann pharmacother. 2009 jul;43(7). ...Read more

Re stopping pradaxa: how many days in advance my scheduled x-stop spacer implant back surgery should I stop taking this blood thinner? I take a 150mg capsule twice a day. I started this prescription on 11/17/2012 and prior to that I took 7.5mg Coumadin

Re stopping pradaxa:  how many days in advance my scheduled x-stop spacer implant back surgery should I stop taking this blood thinner?
I take a 150mg capsule twice a day.  I started this prescription on 11/17/2012 and prior to that I took 7.5mg Coumadin

A week: For aspirin, Plavix (clopidogrel) or non-steroidal anti- inflammatory use recommendation is 7 days preop. When on warfarin, when INR normalizes. For this drug, INR is not affected so one should use same guidelines as Plavix (clopidogrel) which is 7 days according to manufacturer. ...Read more

Can i get a tattoo while on blood thinners? I take 4mg of warfarin and my INR is 2.7

Why chance it?: Might work out ok but then again might not. Would be a shame if you got a huge hematoma under all that pretty expensive art work. Your chances of bleeding are increased. Why not wait until after anti coagulation is discontinued? ...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

See if position.: Normally I would say that you are OK to watch and see how things go, but since you are on warfarin, you need to be more proactive. I would go to an urgent care or emergency room to get checked out. Just to be on the safe side. Good luck. ...Read more

Do blood thinners like aspirin or warfarin help in slowing down vascular dementia caused by mini strokes that is caught at a very early stage?

Do blood thinners like aspirin or warfarin help in slowing down vascular dementia caused by mini strokes that is caught at a very early stage?

Vascular Dementia : There has been no evidence to suggest that blood thinners, such an anti-platelet agents (e.g. Aspirin, plavix) or anticoagulants such as coumadin, (warfarin) slow down the progression of vascular dementia. Aspirin is good for general cardiovascular health, but there is no medical data to support it's use in preventing or slowing dementia. You could still consider Aspirin for your cv health if recommended. ...Read more

With chronic a/f and severe nosebleeds, i'm off warfarin and using aspirin. With no antidote to new anticoagulants, what are my options as i age?

See ENT doctor: In general, atrial fibrillation does not cause nose bleeds. However, anticoagulants certainly may. You need a good look at the side of the nose by a rhinologist (nose specialist) to determine whether there is a blood vessel that could be cauterized. There are several areas of the nose that are the sources of bleeding. The doctor can determine the site and hopefully stop this problem. ...Read more

Had 2 uedvts. On warfarin for life now. What are the chances of getting another clot while on anticoagulants? I'm scared of stroke, pe, heart attack..

Hypercoagulable?: Did you get workup for hypercoagulable state? Abnormal clotting factors and blood proteins (protein s, protein c) may put you at lifelong risk for stroke and thrombosis. Coumadin (warfarin) is not a 100% protection (changes with diet or diarrhea etc, and you may need to stop Coumadin (warfarin) for pregnancy or surgeries). Worthwhile getting the full workup (hematology). ...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

Anticoagulant (Definition)

Anticoagulants are any of a variety of drugs which decrease the body's ability to make or sustain blood clots. They fall, generally, into two categories. Drugs like Aspirin and clopidogrel (plavix) prevent platelets from forming the initial stages of a clot. Drugs like warfarin (coumadin) and dabigatran (pradaxa) block the later process ...Read more
