Coumadin diet

 Coumadin is a medicine prescribed for people at increased risk of forming blood clots. It reduces the formation of blood clots by blocking the formation of certain clotting factors. It is used to prevent heart attacks, strokes, and blood clots in veins and arteries and also used for other medical purposes. Coumadin can prevent harmful blood clots from forming. To help coumadin work effectively, it is important that you keep your Vitamin K as consistent as possible. Sudden increase in vitamin k may decrease the effect of coumadin. On the other hand lowering your intake of vitamin k may increase the effect of coumadin. Monitoring of the Coumadin effect is performed with a blood test. This test is known as the prothrombin time and international normalized ratio. Coumadin is only available by prescription, and should only be taken under the supervision of a physician familiar with its indications and actions. Here are some of the foods you can't eat while taking Coumadin.

List of foods to avoid while taking coumadin:

1. Green leafy vegetables: Some of the green leafy vegetables include kale, collards, spinach, turnip greens, beet greens, mustard greens, dandelion greens, lettuce, brussels sprouts, sauerkraut, broccoli, green onions, parsley, green peas and asparagus. These vegetables are high in vitamin K and can decrease the action of Coumadin. If you take these vegetables, be sure to eat a consistent amount from week to week. Ask your doctor first if you have a history of blood clots and persons on blood thinning medication. Recommended dietary allowance for vitamin k is 90 micrograms per day for woman ages 19 to 70+ years and 120 micrograms per day for men ages 19 to 70+ years. Try to keep the amount of these foods in your diet about the same from week to week. Generally, the darker green vegetables have a higher vitamin K content.

Foods to avoid or carefully considered while taking Coumadin is listed here only as a reference. You should consult with your doctor as everyone's condition is different and drug interactions should be consulted with your physician.

2. Green tea: Another food you should completely avoid while taking coumadin is green tea. Green tea is extremely high in vitamin K and small amounts of green tea can cause complications. If you drink tea, you can take black tea because it is not high in Vitamin K. An example of black tea is orange pekoe tea.

3. Grapefruit and cranberries: Avoid grapefruit, cranberries and its products. Cranberry products and grapefruit products may either increase or decrease the effect of coumadin or warfarin.

4. Herbal teas and supplements: Do not take herbal teas and supplements while taking coumadin. Avoid herbal teas such as chamomile, tonka beans, melitot and sweet woodruff.

5. Fruits: Fruits high in vitamin k include blueberries, kiwi, canned pumpkin and canned pumpkin. Avoid these fruits while taking coumadin.

6. Meats: Some of the meats to avoid include beef, liver and pork liver. These meats contain varying amounts of vitamin K.

7. Smoking and alcohol: Smoking and alcohol should be completely avoided with coumadin. Smoking has very sporadic effects on effectiveness of Coumadin and should be completely avoided.Alcohol is another beverage that can enhance warfarin's effects, prolonging bleeding times.

8. Other foods: Other foods avoid while taking coumadin include cashews, mayonnaise, canola oil, soybean oil, cilantro, garlic, dried thyme, ginger, gingko biloba, feverfew, fish oil, okra and turmeric. Mayonnaise, canola oil and soybean oil have high amounts of vitamin k.

Aspirin and Coumadin:

Another non-food that needs to be avoided is Aspirin, as it also causes blood-thinning effects. However, others disagree as you can see in the comments below. Talk to your doctor about the interaction between these drugs and whether you can take both.

      I have been on Warfarin for 3 years now. I cant believe what some of you are saying, WHY are you guys taking meds that you don't know what it is about. If your DR. puts you on meds ask right away what its for an how you should use it. You can trust what your Dr. says in what he is doing but you should also ask for paper work on all new meds. Plus I know when I get my meds filled at my pharmacy it comes with paper work on how to use it an what its for. Good luck to you all.

      Wow, wow, wow! There is so much misinformation in this article that I wouldn't even know where to begin. Readers, please check with other sources before basing what you eat on this alone. Blueberries are low in vitamin K for instance, NOT "very high"as stated (only 28 mcg per cup). Green tea is not "full of vitamin K," in fact, green tea enhances the effect of coumadin by further thinning the blood. There is absolutely no reason to avoid cashews, onions, olive oil, mayonnaise, tomatoes, dried thyme, etc. ESPECIALLY aspirin! This is insanely harmful bad medical advice being doled out!

      I have been on Coumadin for years, home test weekly, have been takng a daily aspirin to protect my heart, and my INR is always within the correct therapeutic range for my atrial fibrillation. Always. If I followed the poor and dangerous given here, my INR would be bouncing all over the place and I'd never be able to stick to the bland diet that is being recommended. This is ridiculous. The only foods I avoid are those that are *actually* very high in vitamin k: dark, leafy greens. Other than that I can eat anything in moderation. And so can you. Do the research, people!

      Great to read everyone's experiences with Warfarin. Sticking to the same diet, excluding greens, alcohol, broccoli has kept my INR perfect.

      I've only recently read of cutting down on avocado, cashew nuts. onions, tomatoes, olive oil, peanut butter and yoghurt, which is daunting as some of these are my favourite foods, but as I seem to be doing fine I think I'll just ignore it. It's bad enough having to put up with the side effects of tiredness, mental confusion and bruising.

      I have never heard such a load of rubbish. I have been on this drug for 13 years now and have always eaten a varied diet and have had no dramatic effects from diet (including alcohol). The real danger arises when taking antibiotics and steroids and pain killers, especially concurrently, but even then, if you're aware of the effects and take blood test reasonably frequently you should be okay. Food is the least of your worries. As someone has already said, consistency is the key. If you're going to have a drink, have one each night. I eat tons of broccoli, but because I eat it most nights I don't have a problem with my INR. And as for beef, where did that come from? The important thing is to live your life. When I was put on this drug I decided it was not going to spoil my enjoyment of life, and it hasn't. Life is a balance, so get used to it, know your own body and how it reacts and if in doubt get your blood tested! But don't let it make you miserable.

      I am on Coumadin for 3 months now my numbers are up and down but I have not been consistent with the diet. I actually was not aware how it can affect your numbers so drastically. I'm considering looking into the new drugs for blood thinning. Has anyone experienced them?

      I really find this article amusing! 80% of the foods listed here are completely safe to eat. This is just another example of going extremely overboard of what you should and should not eat. Just stay away from vitamin K (green leafy vegetables), grapefruit, cranberry juice, and alcohol and you will be just fine.

      I have been on Coumadin for 18 years for a clotting disorder, at first I was so stressed, but you need to live your life. I drink alcohol ( in moderation), I drink tea, I eat pumpkin, I take vitamins, if you avoided everything your life would suck. I have been on the same dosage the entire 18 years and I am still alive. Be cautious, but use common sense, telling someone to NEVER eat pumpkin or drink tea is ridiculous.

      Don't your doctor's will get you there, there have been cases were patients had to be on 50mg in order to get your INR correct because everyone have a different tolerance or reaction to this drug. I'm not a fan of it but if it's going to save your life what are you going to do? The blood clots are much dangerous that is why the doctors are willing to take this risk with this rat posion. Good luck to all and I pray that these blood clots leave everyone body so the word coumadin will be a word of the pass.

      I have been on coumadin since 1993, as I have a genetic defect which causes my blood to clot too quickly. There are times when my INR is irregular but 95% of the time, it's fine. I consistently eat a lot of greens and always have. I do try to watch for other sources of Vitamin K, so as not to overload on it. Just found out that both cherries and cranberries have a lot of Vitamin K, which I did not know. Coumadin can work. Don't get discouraged.

      I think this is an interesting read, but I am young, and have been on warfarin for over 10 years now. I eat green leafy veg, red meat, garlic and many of the things on this list - the keypoint to stress is to be consistend with what you eat. By doing this my INR has remained stable over the years. The first year or 2 was bumpy, but you soon learn what effects you. Take your warfarin at the same time each day and try to avoid too much alochol - as this is generally the reason my INR becomes elevated :-). Sometimes if you become sick or get a cold, this can also effect your levels. I will be on warfarin for life, but you can still eat things you love - just be consistent! There are plenty of worse medications to be on...

      Never have been a fan of taking poisons, especially rat poison (Warfarin/Coumadin). The side effects of these and many other drugs is so bad, the condition you have is not that serious. Taking Omega 3 complex thins the blood's viscosity and has many other benefits as well. Yes, a drug blocks vital body needs for health. Eating a normal healthy diet including some greenies is essential for health, digestion, heart, bones, liver, etc. Avoiding hype diets: raw food diet, all fruit diet, no red meat or eggs diets, all are counter to the body's needs and health. Because of all the nonsensical diets, I went to study nutrition and health. I take Shaklee supplements because they do not contain fillers nor chemical or ridiculous ingredients and #1 in supplements, so I can recommend them to my health consultancy clients. At 75, I learned hard way to good health as I take no drugs nor have osteoporosis, etc. I eat all God's foods and avoid the fatty, greasy, fried foods and pizza and sugary junk sold everywhere. I love my steak, I bake my own goodies (just reduce sugar count), watch intake of any dairy (hard on the body cells), grains (high sugar and low healthy nutrients), and very small intake of fruit (due to frustose and the liver not able to handle it), exercise, enjoy my cold beer. If a genetic problem is there, then obviously something has to be done to help correct it. Taking serious drugs always block something else that the body needs. Take drugs only for a short period of time and not for a lifetime. Request pig or cow valves instead of a stent due to the dangers of a stent and the need to take drugs forever! whereas with animals you don't. Do the research of Random Control Trial reports and be informed. Today's doctors know little about real pharmacology but the information is out there so spend a little time informing yourself. Taking supplements is a necessity in today's world with GMO foods, over-worked land growing vegetables, using artificial pesticides, organicides, and "junk food" on the gardens instead of natural untouched manure to renew the life of soil - all in the cycle of life and good health.

      After reading ALL of these comments, I have found that patient/doctor communication is not what it should be! I can only say pressure your doctor to give you what you need to "normalize" your life. Interrogate your doctor about your care like you would your child for coming home after curfew! My doctors give me information on everything I have asked for except one thing and that is why it happened in the first place. My encounter with a blood clot was during child birth. I developed a large clot behind my knee. I was given a compression sock & warfarin for six months and went on with my life. Needless to say I developed the most ugliest varicose veins that I learned later is referred to as DVT. My child is 18 now. A couple years ago I experience a cramp in my calf so bad that I couldn't walk. My calf was hard and I couldn't flex the muscle. I had to walk on my toes for about 4 months. When the problems finally passed, I didn't think of it again. Even the varicose veins looked better! I do lots of walking, it's my favorite exercise. I notice early last year I was getting short of breath walking short distances. One day I woke up to start my day and couldn't walk 5 feet to the bathroom. My breathing was rapid. My child called for the EMT to take me to the hospital. I had a saddle pulmonary embolus. If I can invoke some religion, it was by the grace of God I survived. I only stayed in the hospital 6 days, 3 of them in ICU. I went home with a supply of Lovenox and warfarin. That was a year ago. My INR only changes when I change my food choices. It help to know what the affects of certain foods are with warfarin. Check out that PTINR.COM it has a vast amount of information to help you can prepare a proper nutritional plan and maybe get your INR consistent. Another site is, it deals with this and other health issues that are affected by what we consume. Also as a sidebar, I was denied social security benefits, too - 4 times! I have other health issues too - slipped disc and back spasms and vertigo were not enough to approve my claim! But that's another argument for another day! I know I said a lot here, but communication with your health care provider is the best way to get this med & your diet to be friends!

      I have been on warfarin for two years now and my levels have not been in range since January 2011. They make me skip days, eat a large portion of green vegetables and still it is to high. Every now and again it is to low but can't really seem to get it in range. I was wondering if I was the only one tired and after reading all the post I see that I am not. What a relief. Hang in there everyone, hopefully one day soon the doctors will figure out how to regulate our INRs.

      Hi - why don't you jump over to my hubs and read up on warfarin.


      I am concerned about the side effects I see you listing. I know that hair loss is normal. I had that myself when I first started on warfarin. The rest sound severe and not typical. I know some people on my hubs have switched to Lovenox with good results.

      Aspirin and bisoprolol isn't as effective because aspirin doesn't work on the type of clots that form in a-fib. In a-fib blood pools in the heart. When blood pools, the glue in our blood, fibrin, starts to glue platelets together. Warfarin and Lovenox change how fibrin behaves.

      My husband has atrial fibrulation - or irregular heart beat. He's been taking warfarin for several years now. I am concerned for the side effects, including short term memory loss, irritability, lack of concentration, disrupted sleep pattern,joint and muscle pain, stomach cramps and loose stools. He is exhausted most of the time and suffers leg pain when walking any distance. hE STARTED TO LOOSE HIS HAIR. This drug quickly eroded his quality of life from day ONE. He ws a very fit and active man before he started taking it. I have had heart surgery and as a result I take Bisoprolol and one asprin per day to thin the blood. No one has ever mentioned to me any thought of taking warfarin for this purpose. ??? My question is - why is warfarin preferred by most doctors over Bisoprolol and asprin.?????? Can anyone answer thiS

      I took Gabapentine for a long time for neuropathy in my hand. It is an anti epilepsy drug that works in neuropathy by calming down nerves - the same thing that it does in epilepsy.

      If warfarin is bothering you, ask about trying Lovenox. A lot of commenters on my hubs have switched and had a huge improvement. The down side is that it is an injection and a lot more expensive. Warfarin is cheap. It is made out of a substance similar to that in sweet clover and it has been around forever.

      I've been on coumadin for almost a year. I'm tired ALL the time, to the point, that actually after I've slept a good 6-7 hours, I can be up 3 hours, and go BACK to sleep for another 6 hours or so. There was so much alarm about the size of the clot in my left thigh, but after almost a year, nobodoy's bothered to check to see if it's larger(hopefully not) or small. I eat a regular diet, and for a while, my PT test came back at 2.4-2.5, now they're consistantly around 1.8. I also take Gabapentine for neuropathy in my feet. Even the people I talked to at the manufacturer couldn't tell me what it really does, so I think BOTH are just "snake oils" that we're conned into takin', but that's just my opinion. The big drug industry would NEVER rip us off I'm sure! ha

      If you are on warfarin due to a pulmonary embolism it may just be that you are healing. My PE had me out for almost 2 years. Were you fatigued on the Lovenox? If not, it may be the coumadin. Coumadin can cause anemia which causes fatigue.

      I am sorry your dad didn't make it. Only around 4% of people have life threatening problems with coumadin. If you are able to stay in your therapeutic range that number drops even more. It is true though that older people are at higher risk of a bleed than younger. No clue why that is.

She developed a clot in her leg after her heart stopped and they had to find a vein big enough to run a line for heart medicine. One of the risks was that she could've developed a clot and she did.

      Some of this article is correct some is not. Vitamin K that is found is oil, leafy vegetables, chick peas, and some other sources does effect warfarin; however, you can eat those things. Warfarin is a vitamin K agonist. It blocks the effects of vitamin K in the body. If you have more vitamin K you need more warfarin. Consistency is the best route to get this. You can track your vitamin k intake so that you have about the same amount every day - this means you will need about the same amount of warfarin every day. I was on warfarin for one year. It saved my life. I did exactly what I just told you. It meant not having dinner be a giant salad but that I could have a side salad as long as nothing else was vitamin K heavy that day.

      I've been on Coumadin for 4 years and will forever. In the beginning, it took awhile to regulate but now I go monthly and have been in the low-mid range. I am very frustrated about not being able to eat green veggies but I manage. I'm a cook and when (most) recipes call for a green veggie, I get sad. Once in awhile, I might buy asparagus and eat one or two a couple of times a week and that seems to be ok. I do miss all the green stuff as I was a huge eater of all of them. We just have to hang tough and be creative.

      I have been taking warfarin for 14 years due to the replacement of an aortic valve. I have never had any bad side effects; I would say tiredness and headaches are due to something else. I do avoid a number of foods, on the advice of my doctor, but have never heard to avoid beef. I don't eat a lot of red meat, however. I had an episode of A-fib, which occurs with valve patients, but take Atenolol, and haven't had an occurrence since. My INR has gone up and down, and no one seems to know why, but I still think warfarin is saving my life, even though it's a pain sometimes.

      My PT/INR levels were very inconsistent until I changed to a geriatric doctor with more Coumadin experience than the younger doctor. The first thing he did to avoid my PT/INR fluctuations was to take me off of generic (Warfarin) and put me on label (Coumadin). He explained that the FDA only "requires" generic meds to be 80% of what it needs to be. Therefore, while on generics, I wasn't always getting a consistent amount of medicine. Since I switched to the brand name Coumadin, for the first time my INR levels have been perfect (2.5) for two weeks in a row! Hope this helps! P.S. By the way, to the people that ask if it makes you tired ... it definitely makes me sleepy. The doctors say it's not supposed to.

      I also cannot get my INR between 2-3. It keeps sticking at 1.5 or 6. I feel dreadful on this med. I feel tired all the time and I feel my brain is scrambled. Just can't think clearly and want to sleep all the time. Was in hospital for a few days ob as had thunderous headaches and BP was very low. Nobody seemed concerned about that at all! Trying to avoid greens but i sooo love all the foods you ahouldnt have. But... i will do as the doc says!! Warfarin has to be a life saver so what else can you say. Anyone else feeling so tired permanently and just no energy or suffering blinding headaches?

      Hello I'm a patient that has been on wafarin for quite a while now and I'm pretty young in age. I'm currently taking 10mgs. every night and sometimes I get phone calls from my doctor stating to take higher or lower dosages and I'm really fed up with the whole situation because it seem like I'll be taking this medication for the rest of my LIFE!

      I hate this megication.My mother has been on this crap for 16 years and they have NEVER been able to get it regulated. She watches her diet closer than anybody I know and still its not regulated. She has horrible bruses on her body and her Dr still says her blood is to thick.I worry that she is going to start bleeding one of these days and not stop.This is a bad medication and because of what I see her go through I will never allow a Dr to put me on this crap.

      You must drink plenty of water to prevent additional clots while on warfarin/coumadin.

      After almost eight years on Wafarin and a steady PTINR, the PTINR went WACKO; sometimes high, sometimes low. No change in diet. Following a month long battle to keep regulated, I finished taking that bottle of wafarin. Now, a new perscription...same dosage...PTINR is staying regulated. I decided the culprite was an inconsistant dosage in each pill of Wafarin from the previous perscription. It's as if the medicine in the bottle was an in-between batches? or an in-between quality control check? I do not know. I do believe it was the level of wafarin in each pill that was 'off'.

      Bottom a healthful diet, be consistant in maintaining that diet, and obtain regular PTINR checks.

      I have been taking coumadin since 2000. I had pulmonary emboli and was in hosp for two weeks. Have been on med ever since. A test determined I will be taking it for the rest of my life. My INR hasn't been higher that 4.8 in all those years. I do not eat dark green leafy vegetables, I do eat peas, light or red cabbage and asparagus occasionally and I eat iceberg lettuse about once a week. I think concistancy is the key and the fact that I have never liked many dark green leafy vegetables.

      After reading your comments, I thank God that I live in Canada. I'm 2.5 yrs post surgery to replace my aortic valve and aorta; part of the recovery is 3 months of going to a Heart Health Clinic with classes in exercise, diet and nutrition as well as support from nurses, specialists in diet and exercise. The cost of all of this? $0.00 (and the total bill for my surgery was $10.00 for pre-surgical cleansing pads. Boy have you guys missed the boat on health care!

      I've been on this for 2 yrs. and seeing others comments makes me thankful for my doctors. They did tell me what to eat and how to eat. We also have a coumadin clinic that all the doctors send patients to in our area. I call it the "coumadin club" . I thought the clinic was a crazy idea, but maybe not. My inr has been consistent until the last month or two. Trying to figure out why mine is changing since I haven't changed meds. or diet.

      ER doctors just found multiple clots in my lungs and I am in my 5th day of coumadin and Levonox shots. Doctors told me to avoid or be consistant with Vit K ie leafy green veggies but in no way was I told just how extensive the food and herb list was! Not even the warning which came with my Rx disclosed it! My levels have only gone from 1.1 to 1.4. I now have a good idea on just how long and complicated this regiment may be. DARN!!!Thank you for the info and the postings.

      Thank you for the info. Dr.'s do not go over this enough. It seems everyone, I know, that starts this medication is confused about what not to eat and what to eat. No one tells you it has to do with vitamin K. That consistency is the key word and to always meet your scheduled testing. This medication is life saving and my Mother would have died years earlier without it. So we had more precious time with her. Thank you again. very informative. Thanks for your comment Gliska!

      Controling your INR is a very difficult maze to get through. But I just survived a scary spike of 11.9 with the ER's doctors asking what kind of life saving measures I wanted. I don't eat red meat and have avoided all green vetgetables. The doctors say sometimes this may happen for no reason. Good Luck to everyone out there.

      It is unfortunate the title of this article is wrong. As a veteran of warfarin (Coumadin) for over 20 years and having developed the world's largest single site for vitamin K products - the standard counseling for patients is: consistency and communication. Patients avoiding foods in vitamin K run the risk of bone density issues. Vitamin K plays an important role in our body. Clinicians can move the dose of Coumadin around a consistent vitamin K diet provided the patient remains relatively consistent and communicates significant changes in diet. will provide patients and familes a no-cost, no login resource to help make healthy choices while on warfarin. "Not Eat" should be replaced with "Eat consistent amounts, communicate your desires and keep your scheduled INR tests". Home INR testing has been proven to help stabilize blood test results while allowing 'normal' healthy diets. Email me with any additional questions. Gary

      Very informative article. My dad takes Coumadin. I wonder if he is aware of what he should not eat. Sometimes doctors do not give out all the information that should to patients.
