In a discussion on Metoprolol earlier today, I offered the following about Eliquis. You may find it useful.

Eliquis is an anticoagulant formulated to prevent blood clots from forming in the heart's upper chambers. I have been on another anticoagulant (Coumadin) since 2014 when I was diagnosed with Afib. My medical team said I should take it regularly, perhaps for years, to prevent clots from forming in my heart and traveling to my brain where they could cause a stroke. I remain on the drug although my Afib is virtually asymptomatic; I have no conscious recognitions of arrhythmia in my heart. But when I mishandled the Coumadin once in 2016, I suffered a "small stroke" that has left my nervous system slightly off-kilter — no more strokes, but balance, memory, eyesight, smell, and taste (maybe more) are all affected somewhat. I have been offered Eliquis to replace Coumadin, but I have not felt it wise to make the switch, partly because clinics and hospitals sometimes don't have the Eliquis antidote on hand for emergencies that could allow a brain bleed to be devastating or deadly.
