I used to use an inhaler occasionally, and it was powered by CFC. Then recently I had to use one again, only it now had HFA. Not only did the inhaler NOT work, it made me feel worse, and have tachycardia. I used a different inhaler - instead of beta agonist, a steroid, again with HFA, and had even worse symptoms. It is the HFA NOT the underlying drug. How do I file a case to add to the post marketing data base FDA keeps.
