Hi Terry. I am a family physician in the states and this is just advice since I dont have your complete medical history, so you need to still contact your cardiologist or PCP. Since you are on pradaxa and not coumadin, you should not have to worry about the increase in fruits and vegetables. Your right as far as the greens, they are high in vitamin K, which is an antidote for coumadin and reverses its effect. However, since there is so much benefit in leafy greens, I often tell my patients, that as long as we monitor closely, and the dietary consumption doesnt change drastically, that they can go ahead and eat them. Worse case scenario I increase the coumadin some. The problem would be if someone was eating Kale 4 times a day, I get them therapeutic, and then all of a sudden they read something about greens and stop eating kale, and their INR goes through the roof, of course those scenarios are few and far between. Pradaxa is a direct thrombin inhibitor, so we dont have to monitor INRs, YEAH! And that means the mean green is ok for you. Just a few things that might end up in your diet/juice/herbal supplements, that may interact are: 1) Avoid St. Johns Wort, chamomile, and red clover. 2) Dont over do Flaxseed, Garlic, Ginger, ginkgo, ginseng, green tea, willow bark and fish oils! Good luck!
