I agree with caring. albeteroul is strong, I am suprised your doctor subscribed it for exercise induced asthma. Ask him for an atrovent inhaler. it will open up your airway for exercise and won't make you shakey. I use combivent whichis atrovent and albeteroul combined. My son had an atrovent inhaler when he was younger he had exercise induced asthma.If someone is using albeteroul for maintance that means that their asthma is not under control. I use pure albuterol only when I am sick and that's with a nebuilizer and boy I cannot even have cofeee or i am so shakey I can't stand it.,
