Ok, orkambi day 5. Finally I can breathe again. It has been truly "hell week" as they call it. Aweful chest tightness and sob from 2 hrs after the initial dose. I was using albuterol nebs 4 to 5x a day to get any relief. Hang in there guys, the s/s will dissipate!! My fev 1 was 47% a month ago and i went to clini yesterday to make sure they werent dropping because I felt so terrible. My fev1 actually went up to 49%!!!! Today i feel less sob and less tired, much looser cough and hopeful that this med will get me up in the 50's for the first time in years! Fingers crossed!!!
