I was "pre-warned" the hard way. Doc said they will outlaw the present delivery system so I may as well get used to the new one. The albuterol is supposed to be the same.
From what I know the albuterol is the same but the delivery system is much weaker. A respiratory therapist I know said the old propellant sent the medication deeper into the bronchia where it could provide the most relief. The new delivery system requires deeper inhalation as you spray it. Obviously these idiots have never had an asthma attack where inhaling is impossible. Good luck to you.
