Hi @cecilias, I moved your message to this discussion where you have connected with other members who know your story.
Discontinuing tykosin if you're no longer experiencing a-fib is certainly a discussion to have with your doctor. Has it been established that hydrocortisone caused the a-fib? Has the a-fib completely disappeared? What side effects if any are you experiencing from the prednisone? Good questions to ask a cardiologist who knows you.
