Allergic reaction management to local anesthetics typically involves which approach?

• A. Epi for immediate, Benadryl for delayed
• B. Steroids only
• C. Oxygen only
• D. Antibiotics

Answer: (A)

When a patient has an allergic reaction to local anesthetics, the priority is to treat potential anaphylaxis quickly. Epinephrine is the first-line intervention because it reverses the dangerous airway swelling, improves breathing, and stabilizes blood pressure. If symptoms are controlled or milder after epinephrine, an antihistamine like diphenhydramine can help with itching and hives that may appear later, but it does not address the most dangerous aspects of an immediate reaction as effectively as epinephrine does. Oxygen may be provided if there’s trouble breathing, but it isn’t a stand-alone treatment for the reaction. Steroids can be used as an adjunct for prolonged or biphasic reactions, but they take hours to work and aren’t the initial treatment, and antibiotics have no role in acute allergic reactions to local anesthetics.
