I am asthmatic, I have been taking salbutamol inhalor for the last two years, I have tremors now under stress. Please help, tell other medicine if nee?

Asthma. If you need to take the rescue treatment very frequent, that means your asthma is not under control and your physician may need to upgrade your treatment to include inhaled corticosteroids ( like advair, flovent, symbicort (budesonide and formoterol)...Etc). A good alternative to salbutamol with less tachycardia and anxiety would be Levalbuterol ( xopenex).
