My 17yr son just was diagnosed with exercise-induced bronchoconstriction. We are working with his pulmonologist to try and find a medicine that will help him. He runs XC country and track. He only has problems about 2 miles into a 5k race. His whole body and chest tightens up from low oxygen. He uses the albuterol inhaler before races. It helps some but the cold air seems to exacerbate the problem. He recently tried adding Asmanex inhaler daily but it doesn’t seem to be helping anymore that the albuterol inhaler pre-race. He recently ran at State and had to keep slowing down to feel relief. Any help on what medicines helped for EIB is appreciated!
