I was using an inhealer for awhile this past month, really trying to get my asthma under control.
What I found works for me
is getting a
nasal steriod
spray, like Rhinocort Aqua, Nasacort, etc., After I started using this at night it opened up my nasal areas ( which I did not realize were clogged), then I use the mouth inhealer in the mornings and that seems to work for me.
Since I don't know your situation, please make sure that you don't stop using any medication and have a attack.
