@merpreb that is what the docs and the pharmacist told me. Maybe the non medical term is "rescue" inhaler. As long as it's used properly what difference does it make? I just know it is the only one they want me to have. I just saw the pulmonary doc last week. I asked about new, additional or more effective inhalers he told me there were none, at least for me. That is the same inhaler they gave me 13 years ago, but I'm not complaining. My answer is not a palliative remedy (unless it is end of life-then I want generous access to fentanyl) it is my efforts at rehab-that's all I've got, unless they devise a break-through procedure that reverses the small airway damage.
