Alternative to Prednisone which has many side effects

Posted by 5352938229382709005 on Aug 01, 2016

I ordered this product so I wouldn't have to take Prednisone. Using for Interstitial Lung Disease. An MD uses for his patients with lung issues. So far I have not had any real trouble and it seems to be doing a good job, no infections. Only take 1 at night. Plan to be taking a lot time as I continue to feel welll.
