your question little bit of, copd quite frequently use inhalers, i think that it is copd + asthma.copd person stage will be ask on oxygen question.anyway, inhaler can shorten people's life, it is for sure, so i suggest copd people use herb to treat asthma, and use herb to treat copd, and herb can totally recover copd, west medicine to copd can not do any real thing.here is some doctor's websethttp://famousdoctor.org/asthma.htmlhttp://famousdoctor.org/COPD_mullen.htmlhttp://famousdoctor.org/COPD_ulrich.html

The stage that the COPD is not under control. I have had this with my asthma. I started only using my inhaler once a twice a month maximum. Then the asthma got worse. I had to use my inhaler every 4 hours (could not even wait 5 hours) or I would have major problems. This happened for about 2 weeks before I started another medication (surprisingly only an allergy pill, but it WORKED!). Then my asthma problems went away. You should talk to your doctor and have them help you get your COPD under control.
