Final answer:
Type III hypersensitivity reactions are treated by avoiding antigens and using anti-inflammatory drugs, particularly corticosteroids, to reduce inflammation and aid in healing.
Step-by-step explanation:
The treatment for type III hypersensitivity reactions typically involves preventing further exposure to the antigen and the use of anti-inflammatory drugs. Treatments such as anti-inflammatory corticosteroid inhalers may be used to diminish inflammation and allow healing of lung lesions. More severe cases might require systemic corticosteroids, administered orally or intravenously. It is essential for individuals with this condition to avoid the triggers that cause the hypersensitivity response.
