Treatment for angioedema depends on the underlying cause:
- For Allergic Angioedema: Avoidance of known allergens, antihistamines, corticosteroids, and epinephrine (in cases of severe allergic reactions).
- For Non-Allergic Drug Reactions: Discontinuation of the offending medication (e.g., ACE inhibitors) and switching to alternative treatments.
- For Hereditary Angioedema: Medications to prevent or reduce the frequency of attacks (e.g., C1 inhibitor concentrates, bradykinin receptor antagonists, kallikrein inhibitors) and treating acute attacks with appropriate medications.
- For Idiopathic Angioedema: Symptomatic treatment with antihistamines and corticosteroids, and avoiding known triggers if identified.
