atrial fibrillation
"Please, please, please, help educate patients and families about this medication.  My father had been on it for a number of years and developed a toxicity this summer.  He passed away within 2 weeks of my taking him to the ER for toxicity.  WE had never been informed of things to watch for, he had been taken off of the medication, but then put back on it by mistake by medical professionals at the hospital, at double his previous dose.  Reading all of this information available makes me very sad that we were not informed and should have been.  Be as proactive as you can!"
