Do ILD meds have minimal effect?

About 2-1/2 years ago I was diagnosed with ILD. I feel fine and my pulmonary function tests are, for the most part, better than normal for someone my age (78)--except diffusion was down a little. I asked my pulmonologist if I should be taking any of the antifibrotic meds. She told me no because they have very minimal effect. Has that been your experience? I had read that meds should begin early after diagnosis.
