Which medication is administered to a child for severe allergic reactions?

The appropriate medication for a child experiencing severe allergic reactions is diphenhydramine, an antihistamine. This medication works by blocking the action of histamine, a substance in the body that contributes to allergic symptoms such as itching, hives, and swelling. While it is effective for mild to moderate allergic reactions, it can also provide some relief in severe cases, often used alongside emergency interventions.

In severe allergic reactions, particularly anaphylaxis, epinephrine is the first-line treatment, but diphenhydramine may be administered afterward to help alleviate lingering allergic symptoms. It is worth noting that other medications may also be part of the treatment protocol for severe allergies, but diphenhydramine is specifically known for its antihistamine properties and is commonly used in pediatric care for allergic reactions.

Understanding this context helps reinforce that medications like dopamine, methylprednisolone, and amiodarone do not serve the same purpose in treating allergic reactions. Dopamine is primarily a cardiovascular agent, methylprednisolone is a corticosteroid used for inflammation, and amiodarone is an antiarrhythmic medication. Therefore, diphenhydramine is designated as the correct choice for addressing severe allergic reactions in children.
