Albuterol
"It works great as long as you are NOT allergic to sulfa drugs, sulfates or sulfites!  If you are allergic to any of those, you might want to talk to your doctor before you take albuterol sulfate.  It made my asthma worse, every time I used it.  Once I stopped using it, my asthma was nearly gone by the next day.  It turned out that not only can't I use sulfa drugs, I cannot use this medication to quickly stop an asthma attack.  Unfortunately, I know three other people (friends of mine) who had the same reaction to this inhaler. They also, are allergic to sulfa drugs. The drug companies need to come up with an albuterol inhaler that does not use sulfates."
