Many thanks Sue. You always nail it.
Sounds like it is a maintenance drug to use for long terms. I wonder if long term could also mean we can use it for a couple of months. I was diagnosed with eosinophilic asthma last October with bronchiectasis. I coughed for over a year, and multiple doctors couldn't find the cause. I got pneumonia last Feb. When I was treated with pneumonia, blood work showed that my eosinophil count spiked. But it went down by itself after pneumonia was treated. Doctors thought I was allergic to antibiotics.  After pneumonia,  my cough and mucus were still there, all the testing showed nothing wrong with me, they thought I was slowly healing. But a few months later I got lung infections. And this time my eosinophil spiked again before the antibiotics. So the pulmonologist asked me to take wixela this time. I took it for 3 months. Then I convinced my pulmonologist to stop it and see if I am ok without it. He agreed to monitor it. Blood test after 2 months without it, I am ok.  So this is where I am. I probably need to be ready to use it anytime if my conditions get bad. A question to you, do you use it for breathing problems, right?  I always wonder do people get adult onset asthma at 71 years old?
Many thanks again. and take care!

Pleased to hear there is an alternative to Advair. It has been years since l was put on it by allergist. The cost of the medication was shocking. when it's patent expired l was excited...but no generic arrived. I was told by a pharmacist that the method of delivery...the powdered discs it had had not been able to be copied.
so now years later some company found a way!
