If you're taking several medications simultaneously, it could be that just ONE is causing the problem and changing medications may help the issues you're experiencing.

Another thought would be to consider if you have ever had issues with dairy. Most, if not all dry-powder inhalers contain lactose as a carrier which could pose some potential issues if you're sensitive to it (http://aaia.ca/en/milk_proteins_and_allergy_medications.htm). I've also heard of the same phenomenon about people reacting adversely to pressurized metered dose inhaler propellants as Chris mentioned above.

Thank you so very much for answering my question !!

I should have mentioned I also have Asthma

I have taken just about everything, I was on Symbacort for at least 2 years and it was working really well and then around last Feb., it was making me very breathless, so much so that it "put me down" for most of the day---by that, I mean I couldn't get off the couch. I have been on Advair, Duo Neb Nebulizer for at least 6 years , Spiriva,Atrovent, combivent, albuterol with no problem with any of these until last Feb. while taking Symbicort!! That's where it all started and then I was unable to take Advair, Spiriva. Pulmacort, Duo Neb

My reaction is that I cannot breath any medication deeply because it gives the same reaction as I mentioned. I did go to Mayo clinic and they said they too had never heard of anything like this and thought that it is "fear" which it definitely is not !! I think they may have misunderstood me thinking I said my throat 'closes' when I inhale--and it doesn't close!! it's just that if I get the least little bit too much, my breathing becomes very hard ! They also suggested going to an ENT-- that it may be my vocal cords not reacting right when I inhale which is why the Pulmanogist gave my a Bronchoscopy and included a vocal cord exam. Everything turned out fine

I am also, right now, on a treatment of Prednisone, that I'm hope and praying to get off because for the last 3 years, I've been on 5mg per day for RA . What is keeping me going is that I'm using a spacer on my Duo Neb and I can get a little more med. doing it that way but certainly not even 98% of the dosage-----but it keeps my airways open longer--- for awhile

I have not taken Symbicort Turbuhaler nor Foradil aerolizer . Is the aerolizer the same as a Nebulizer?

I am beginning to wonder if my other meds could have some effect ie; Coreg. norvasc, plaquenil,.prednisone, tylonel arthritis. aspirin. simvastatin, Vit D 50000 iu one per week because my internest took me off Lisinopril because it was making me cough a lot , hence, I'm allergic to ace inhibiters

I hope I didn't confuse you too much with all this info and I really hope you'll be able to help me or make any suggestions?

Again, thank you sooo very much!!!
