Radiation Pneumonitis with Dyspnea and Dry Cough After Glucocorticoids Did Not Work
This protocol addresses the clinical situation where dyspnea and a dry, nonproductive cough have developed within 6 months of completing thoracic radiation therapy — most often within 12 weeks — and first-line systemic glucocorticoid treatment has not achieved the expected improvement.
Clinical Scenario
Symptoms consistent with radiation pneumonitis — shortness of breath and a dry, nonproductive cough — arising within the typical post-radiation window. Lung infection has been excluded as a cause. Timing and symptom pattern fit the known presentation of radiation-induced lung injury.
Previous Treatment — Goals Not Achieved
Systemic glucocorticoids (prednisone) were the first-line intervention. The expected treatment goals — marked reduction in cough, chest tightness, dyspnea, and fever, along with resolution of radiographic changes — were not reached. This protocol represents the next clinical step after that failure.
Next-Step Treatment Approach
When systemic glucocorticoids have not produced adequate clinical improvement, evidence from case studies supports the use of specific immunosuppressive agents. The full structured protocol — covering agent selection, approach, and monitoring — is available via the link below.

RP occurs within 6 months of therapy (most often within 12 weeks), whereas RPF occurs > 1 year following therapy.
The most common symptoms are dyspnea, which can be mild to severe, and a dry, nonproductive cough.
However, most experts recommend systemic glucocorticoids to treat significantly symptomatic RP, provided that lung infection has been ruled out.
Single case studies have also reported effectiveness for both azathioprine and cyclosporine.
