Sometimes I get it, sometimes I don't.
I was taking Ventolin between 1 and 3 times a day for symptoms, and sometimes I'd feel it more than others--At the beginning of taking it, I was really shaky, hyper, and had palpitations regularly.
I guess it just depends on your body when you get it or when you dont. If you're concerned about it, ask your doctor if he or she would consider switching to Xopenex (levalbuterol/levosalbutamol)--it supposedly has less cardiac side effects than salbutamol/albuterol, although I haven't tried it.
