Doctors & patients are saying about 'Beat Your A-Fib'...

"If I had [your book] 10 years ago, it would have saved me 8 years of hell.”

"Dear Steve, I saw a patient this morning with your book [in hand] and highlights throughout. She loves it and finds it very useful to help her in dealing with atrial fibrillation."

Dr. Wilber Su,

"...masterful. You managed to combine an encyclopedic compilation of information with the simplicity of presentation that enhances the delivery of the information to the reader. This is not an easy thing to do, but you have been very, very successful at it."

A-Fib & Anticoagulants: Bleeding Risk If combined with OTC meds, Supplements

More than a third (33%) of people taking anticoagulants also take at least one nonprescription drug daily or most days of the week. This combination can cause dangerous side effects.

If you are taking an anticoagulant, such as Eliquis, Xarelto, Pradaxa or Savaysa, be aware that taking it along with some over-the-counter drugs and supplements can cause dangerous internal bleeding.

These over-the-counter drugs include painkillers such as aspirin, Advil (ibuprofen), and Tylenol (acetaminophen) and dietary supplements such as fish oil, turmeric, ginger and other herbs.

Internal Bleeding Risk: NOACs/DOACs Hard to Measure

The older anticoagulant, warfarin, required regular blood tests of INR (International Normalized Ratio) to measure how much warfarin was actually working in a patient’s blood to prevent a stroke.

But the newer anticoagulants (NOACs, DOACs), such as Eliquis, Xarelto, Pradaxa or Savaysa, aren’t normally measured by anticoagulation clinics or health care professionals using standardized tests such as INR. (The FDA, under pressure for new anticoagulants, approved the NOACs without there being any established or universally recognized method of determining their clot preventing effectiveness.)

Be aware that your doctor probably doesn’t test to see how much your NOAC is actually working in you. They hope it is, but doesn’t know for sure. Blood levels of your NOAC depends on factors such as how well or how poorly your kidneys are functioning.

Not all of your NOAC may actually be working for you. Pradaxa, for example, is 80% cleared by the kidneys. This means there may be lower anticoagulant levels in your blood stream, and a lot of your clot prevention is being flushed away by your kidneys. (Eliquis, Xarelto and Savaysa fare better with only 25%, 33% and 35% being cleared by the kidneys, respectively.)

Check With Your Doctor About Increased Internal Bleeding Risk

If you take an anticoagulant along with over-the counter drugs and supplements, ask your doctor which combinations to avoid. But be aware that many doctors are clueless about natural dietary supplements.

(Don’t ask them how effectively your NOAC is working in you. They probably don’t know and can’t easily test for that.)
