Hello Doctor, I hope you will safe and sound. I wanna tell you my mother is a serious ILD patient. Her treatment is started for the last two years. She is regularly taking six or nine tablets of pirfenex 200 mg. But her condition is continuously diminishing. Due to low oxygen, she is also provided with supplemental oxygen through oxygen concentrator. I want to know, is there any alternative with which she can be treated and her status can be improved. Thanks.
