Pacemaker & Diet
An_243711 posted:
I am 80 yrs of age. I've recently had a Pacemaker implanted .I now take Coumiden once a day. I understand that I should not take anything with Vitamin K in it and that includes green vegetables. That means that most vitamin supplements has it in them. What can I take in place of Vitamin K or how much can I really take of it?

I have been taking vitamin supplements for many years but recently I've been told not to because of the Coumidin.

In general, this is not true.

As another member duly noted several months ago, and having been on Coumadin-therapy for almost 29 years, he learned that one can eat all the greens/green leafy veggies one wants, that is, just AS LONG AS one consistently eats the same veggies/the same amount each day/every week, and with the Coumadin dosage being adjusted accordingly, one should do fine.

Additionally here, for those on Coumadin-therapy, as reported, it is best to manage Coumadin/warfarin according to the International Normalized Ratio (INR) guidelines.

For most clinical conditions/situations, an INR of 2.0/2.5 to 3.0 indicates the appropriate dosage. An INR above 5.0 can be dangerous. An INR of 1.0 indicates no Coumadin effect/benefit at all.

The best way to maintain a proper (appropriate for one's specific condition) INR coumadin level is to basically keep one's diet (food, which includes those that contain vtamin K, and beverages), prescription drug-therapy, etc., the same from day-to-day.

As applicable, a change/changes in metabolism (or other factors and conditions) can sometimes be responsible for fluctuating/different levels of Coumadin.

Most important, communicate/interact well with your doctor(s) at all times.

Best of luck down the road of life.

Special WARNINGS about Coumadin (warfarin)

Treatment with so-called blood thinners (it actually does not do that) may increase the risk that fatty plaque will break away from the wall of an artery and lodge at another point, causing the blockage of a blood vessel. If noticing any of the following symptoms, contact your doctor immediately -

Abdominal pain; abrupt and intense pain in the leg, foot, or toes, blood in the urine, bluish mottling of the skin of the legs and hands, foot ulcers, gangrene, high blood pressure (hypertension), muscle pain, purple toes, rash, or thigh or back pain.
