You were dx in 2006 and I assume you are seeing a Dr. as you have a RX inhaler. ProAir (albuterol sulfate) Inhalation Aerosol is indicated for the treatment or prevention of
bronchospasm with reversible obstructive airway disease and for the prevention
of exercise-induced bronchospasm. If you are out of your inhaler and you continue to be SOB with exertion you should contact your Dr. for further instruction.
If you feel you are in a medical crisis present to the closest ER or call 911.
Wishing you the best and hope you seek the help you need.
