I am new to this and am not sure how to post. An overdose of Tirosint (pure T4 thyroid hormone) caused AFib. Despite having a history of my blood not clotting in time, I was put on Eliquis. It was and is trashing my sensitive GI system. It contains lactose, which I cannot digest, and I am chemically sensitive. I had dose reduced to lowest available. I still have problems. My back broke out and dermatologists gave me creams. Anything that touches or compresses my body causes itching or rashes. I also have flushing. None of this predated the diagnosis, and I have to wait three months to have Watchman device implanted so I can get off this drug.
