The doctor has me on a different drug: OFEV (nintedanib). After 3 weeks - no big side effects. My blood is tested every two weeks. First test was normal. Another test this Friday. The hope is that it stops the progression of the fibrosis. It does not usually reverse it. It was approved a few months ago. In the mean time, I cough but don't feel ill and am able to do whatever I want to do. We walk at least 2 miles per day - mostly on the beach or downtown to get the mail. I call it the "nintendo" drug as pronouncing nintedanib is beyond me.
