New, safer drugs called novel oral anticoagulants have emerged, so while we hadn't had good alternatives for warfarin in the past, we now. DEAR DOCTOR K: I have atrial fibrillation. For years I took warfarin. Last year I switched to Pradaxa. Now I hear Pradaxa may not be as safe as. Thus achieving the right balance of the risk of stroke versus serious bleeding is the goal. Coumadin (warfarin): Pradaxa (dabigatran): Xarelto (rivaroxaban): Eliquis (apixaban): Savaysa (edoxaban). In this Q&A, Dr. Weil answers a question from a reader wondering about natural blood thinners, Coumadin side effects and possible Coumadin alternatives.
I have written on this matter intermittently in the last year or two as new alternatives to warfarin have become available for patients with atrial fibrillation.
