My mother, 70 years, just visited me and is on Advair Diskus, I want to say at least 2 years now. She has COPD with chronic bronchitis. I don't even know this woman anymore. She is depressed and extremely short with everyone. She has a rash that started on the back of her legs that fills with fluid then scabs. She has informed me she has had the rash almost a year now. It has spread to her arms and neck lately. It comes and goes in it's severity. Her Dr. cannot give her a diagnosis. She too, has spoken the words "miracle drug" in the beginning. I just got off the phone with her and she said she would rather risk an asthma attack than stay on Advair. Risk death than stay on Advair? What is this drug doing to people?
