All I can say is that in my case it worked very well.
Keeping the lungs working properly is key.
It is important that you know how it works though. I do know someone who told me it made her cough more so she stopped. Told her to start back up right now as the purpose was to get the junk out of your lungs.
Use a nebulizer. In through the mouth out through the nose. Have a waste can and lots of kleenex handy. Drink plenty of water or herbal tea. No dairy. Ask your doctor about taking Mucinex (guaifenesin) as well.
You are going to cough. A LOT. You may even interrupt your treatment to cough. For about 15 minutes to a half hour. Then you will breathe easier.
Four times a day for me.
First treatment of the day is the worse. Not pleasant.
Better then dying.
“out through the nose”
Yeah.
Used to avoid exhaling Symbicort through the nose because of irritation, but now do.
