Is it dangerous to use albuterol everyday to help with shortness of breath if you only use it when you exercise?

Maybe. It sounds like you were given the albuterol inhaler to help with shortness of breath or wheezing during exercise...And that perhaps now you are having symptoms everyday. It certainly seems like your symptoms are changing, and if they are you should see your doctor to review your new symptoms with them. If you are having to use your inhaler more than usual, see your doctor.
Is this a change? Is this the way you were when you were given the inhaler? I am going to bet not. I suggest you talk to your doctor.
