Q. I have been taking Coumadin (warfarin) for years, however, my doctor recently recommended that I switch to Xarelto or Eliquis. I am looking for more information on Eliquis to evaluate the pros and cons. Your help will be greatly appreciated.

A. We have consulted a cardiologist at the Cleveland Clinic who deals with atrial fibrillation (AFib) on a regular basis. He is cautious about the new medications because he says it is hard to assess their effectiveness in any given patient.

Unlike with warfarin, there is no easy blood test to tell when you have achieved the optimal blood thinning effect. He also pointed out that it is hard to reverse the anticoagulant effect. There is no “antidote” to an overdose that might lead to hemorrhage.

Many patients may do quite well on Eliquis, but we would hope that a knowledgeable cardiologist would be involved in such a decision and provide adequate oversight. The drug should never be stopped suddenly.


  • The most serious complication is bleeding. Patients can bruise or bleed more easily when on this drug. Notify your doctor promptly if this occurs. Dark or tarry stools would be a possible warning sign of digestive tract bleeding. If you throw up and detect blood or anything that looks vaguely like coffee grounds, that would be a sign that there might be bleeding in the stomach.
  • Let your doctor know if your gums bleed after brushing or flossing your teeth or if you experience nosebleeds or pink, red or brown urine. A bad headache or a feeling of dizziness should also be discussed immediately as these could be signs of bleeding in the brain.
  • Swelling of the joints or joint pain could signal bleeding in that area. Report such a side effect promptly to the prescriber
  • Skin Rash could signal a serious allergic reaction. Report such a symptom immediately. Swelling of tongue or face or trouble breathing also requires emergency treatment.


Do not take any other drugs without checking first with your prescriber.

  • Aspirin (may increase the risk of bleeding while taking Eliquis)
  • NSAIDs (all anti-inflammatory drugs including ibuprofen, naproxen, diclofenac, etc) could increase the risk of bleeding)
  • Other anticoagulants such as clopidogrel or warfarin may increase bleeding risk when combined with Eliquis
  • Antiseizure drugs such as carbamazepine and phenytoin may reduce the effective of Eliquis. St. John’s wort may also have this effect.
  • Antifungal medications (ketoconazole and itraconazole) may increase the risk of toxicity and bleeding. Dosage modifications are essential.
  • Antibiotics such as clarithromycin may also increase the risk of side effects associated with Eliquis.

Bottom line: be vigilant for signs of bleeding and always check about drug interactions before adding an herb, an OTC drug or another prescription medication to Eliquis.

    Had first Ablation last week Cardio. wants me to start using Eliquis and Pataprazole with my existing medication which includes Nuseal Aspirin and a Statin. Diagnosed with AF would get attack normally after a night out or wedding when a lot of alcohol would be consumed.

    What I am very worried about is I am a very active individual gym, golf and walking as I am prone to put on weight and I am worried this new medication will restrict my ability to regularly exercise. Might anybody have any comments recently retired 60 yo. Also not keen on idea of taking both Nuseal Aspirin AND Eliquis. Thanks

    Have been on Elequis now for 8 days after coming off cartia for AFib, now I am experiencing cold/flu symptoms and feel run down, Never was one for getting colds much before so I reckon its this medication.
    Don’t know wether I can stop safely now as read that it can cause stroke etc? what a predicament!
    Does anyone have any input which would be appreciated

    Lord, I agree with you. The cures for a fib, all the $ made by cardio versions and ablations
    Nothing works. Now the drugs are causing dementia.

    Have been on metoprolol, xarelto, eliquis, digoxin, lorazepam and occasional furosemide (Lasix) for a couple years, after a serious episode of a-fib that went into congestion heart failure. Have had a couple of those cardioversions to try to correct heart rhythm, but keep going into A-fib.

    Am presently having serious side-effects from all these drugs and just want to stop them… Have cut most meds down to 1/2 dosage (with Dr. knowledge), but have had about a week of INTENSE SEVERE LOWER ABDOMINAL PAIN (left side) and not sure what’s causing it. May have to go to E.R. for some testing because the pain is so severe and unremitting. Cannot find any comfortable position, and have to lay on back and JUST NOT MOVE to avoid the pain.

    Just did some look-ups in Physician’s Desk Reference for drugs , and they list STOMACH PAIN and LOWER ABDOMINAL PAIN in listings for Metoprolol, Eliquis, Digoxin, and Lorazepam! Also, have learned that many of these drugs can cause dehydration that can lead to kidney stones, which can also cause severe abdominal pain.

    Am starting to feel like having A-fib is better than all these problems from the so-called cures!
