Just a little tweak about Eliquis (apixaban) and taking Advil/ibuprofen, the advice and caution about mixing those two is indeed advisable, and most ethical to tell the patient, including when handing the patient the prescription by also handing a pamphlet about the drug and its possible dangers and side-effects. However, some of that caution can be tempered a bit with more dialog between the patient and the prescribing authority. I'm NOT suggesting you do what I, and some other apixaban takers do, not without consulting your EP or cardiologist, but some of us do take Advil or Aleve...SPARINGLY...and always with food, when the need is greatest, even though we are on apixaban. The reason is that some patients have poor liver function that acetaminophen exacerbates, or that it simply does a much poorer job of controlling their pain than does ibuprofen. In discussion, your physician may agree that you can try it to see how you do. You do want to avoid stomach bleeds, that's for sure. But, if you are a generally anxious person, poor sleep, in pain, and you have a heart condition, the previous points are not good for you.
Again, I'm not qualified to advise you, certainly not against good medical care by a qualified person. However, there is often some wiggle room, and one must do a cost/benefit analysis. A good doctor will have some leeway about prescriptions and how, and when, their patients should use them.

I am far more conscious of what I eat and drink these days, and am constantly looking out for a reaction to what I've consumed, hoping to make a connection. As yet to no avail. At present the medical advice is to be on beta blockers. I do have an underactive thyroid and take levothyroxin, but the doctors are adamant that there is no connection .

If you want to get off Eliquis, you can take Garligin 3x/day) as a blood thinner. I have used it for years as I didn't like Eliquis. It works great for me. 1/5 of the price., no side effects. Made w/ garloc and ginger, known blood thinners.

One of the side effects of eliquis is headache. Which is having you need to take tylenol. Also allergic reaction is a side effect. I am very sensitive to medications also, which is why I take none.
