What is the primary management for Type I hypersensitivity reactions?

• A. Avoidance of allergens and pharmacological treatments like antihistamines and corticosteroids
• B. Immediate antibiotics
• C. Radiation therapy
• D. Immunotherapy as the only approach

Answer: (A)

Type I hypersensitivity is driven by IgE-mediated mast cell degranulation, so the most effective way to prevent reactions is to avoid exposure to the offending allergen. When reactions occur, medications such as antihistamines block the effects of histamine, and corticosteroids reduce the inflammatory response, helping to relieve symptoms and prevent progression. Immunotherapy can be helpful for some patients over time by desensitizing the immune response, but it is not the universal or sole first-line approach for every case. Antibiotics have no role in treating allergic reactions, and radiation therapy is irrelevant to this condition. Thus, avoiding the allergen combined with symptomatic pharmacologic management best addresses Type I hypersensitivity.
