Treatment Protocol
Immediate cessation of exposure to the causative antigen is mandatory. Supportive care includes supplemental oxygen to maintain SpO2 >92%. Systemic corticosteroids (e.g., Prednisone 0.5-1 mg/kg/day) indicated for moderate-to-severe cases to accelerate resolution of inflammation. Monitor pulmonary function tests (PFTs) and CXR/HRCT for resolution.
