Can asthma meds taken for a long time have side effects?

Bronchodilators sometimes cause shakiness and extra heart beats. There are other possible side effects as well but in general aerobid and symbicort (budesonide and formoterol) as examples are well tolerated over a long time and preferable to the alternative, which is having asthma a.
