OFEV did give me stomach discomfort and I kinda experimented around with not taking it and I just decided to not take it. I read that is one of the side effects. It is interesting that even though Pirfenidone & OFEV are both FDA approved to be effective theoretically to slow the progression of IPF but NOT for everyone. There is not any actual facts proving how effective it is for a given individual.
I still have some left so my might start up again. My appointment with Mayo is 11-27-2018 and I have not heard anything to the contrary.
