Unfortunately I happen to have living proof that one works better with little or no side affects than the other. I am 66 years old and never experienced a side affect from using Asthma Nephrin other than immediate relief.
My daughter is living proof that the new meds help in one way but have side affects that are actually worse than the Asthma.
As for Aspirin, my daughter has not been able to use Aspirin since she became Asthmatic.
Primatine Mist is nothing like Asthma Nephrin.
I just remembered, Asthma Nephrin contained a small amount of Chloroform.
Have you considered that your daughters disease may significantly worse than yours ever was?

primatine mist--- epinephrine
asthmanefrin----- epinephrine
When I was a child, I was prescribed Quadranal for asthma. it worked, but contained barbiturates. I remember I didn't like the effects.
Later I used OTC epinephrine until my D.O. informed me that they can be bad for the heart.
Now I use Advair and have been asthma free for years.
