Treatment varies with the severity and type of symptom.
Short-term goals include relieving immediate symptoms. Long-term goals include avoiding future allergic reactions . Corticosteroids such as dexamethasone or prednisone reduce the immune response and may be prescribed to reduce symptoms. Epinephrine is used to reduce swelling of the airways and other life-threatening symptoms. Antihistamines such as diphenhydramine often provide good relief of mild to moderate symptoms.
