Esbriet or Pirfenidone I began taking this medication mid November and quit December 31. The side effects were just to much, headaches, body aches, and greatly increased fatigue. I'm feeling I'm on the down swing health wise hoping I level off and find a new groove. I've needed my oxygen much more often in thr last 6 months but even more so since begin the above mentioned medication. I'm not sure if I'll ever recoup any lung function and my testing for that isn't due again until April. Not many understand just how hard it is becoming for me when I get up and move around to have my oxygen saturation drop to the mid 80's when I'm standing doing dishes and walking up 3 stairs and 25 feet and back to the bathroom I drop to the mid to upper 70's. Before this past summer if I paced myself I could manage without using oxygen. I feel like I'm becoming a burden to my family as I can't do everything I used to even with oxygen. Wondering if anyone else has used the above mention medication and if they felt it made them worse?
