I was diagnosed with afib two years ago and have been on the blood thinner, Eliquis, since that time. I have experienced no bleeding episodes or bruising while on this medication. I am 73 years (young) and do have severe osteoarthritis. i'm wondering what the drug history/ interaction of blood thinners is with arthritis supplements such as glucosamine, chondrotin and MSM ??? I stopped taking those supplements when starting Eliquis; but am now convinced that my arthritis has really worsened without their help. I'm sure there must be many fellow sufferers out there and would so appreciate your input.
