On this issue, it depends mainly on what kind of idiopathic interstitial pneumonia is diagnosed: If it is a type of mechanized pneumonia, some patients will have symptoms and imaging aggravated again during the dose reduction or after discontinuation of the drug, and then re-increase the hormone dose, most patients are effective, but when the dose is reduced again to about the last recurrent dose, the subsequent dose reduction or discontinuation should be more careful and closely followed, for very few patients may For very few patients, small doses of hormones may be given for maintenance, i.e., these patients cannot be discontinued. In other types of idiopathic interstitial pneumonia (which may have structural changes), for example, if someone is trying hormone therapy for IPF, the presence of worsening symptoms does not mean that the increased dose of hormone will be effective, so it is not recommended to use hormone again and consider switching to other medications.
