Albuterol Sulfate HFA and asthma attack

I have used the old form of albuterol safely and effectively for nearly 30 years. I just was made to switch to albuterol sulfate and have instantly had awful reactions. My lungs feel awful. Feel itchy and close up and uncontrollable coughing followed by continued shortness of breath and light hotheadedness and disorientation.

I am concerned about the environment too, but why should I die of an asthma attack to reduce a tiny amount of CFC's.

I am really terrified. Which of course makes my asthma worse just to panic.
