Which term best describes medications used to alleviate severe allergic reactions?

The term that best describes medications used to alleviate severe allergic reactions is "Emergency medications." This classification includes medications that are administered in urgent situations where a person's life may be at risk, such as anaphylaxis, a severe and potentially life-threatening allergic reaction.

Emergency medications are designed to act quickly to protect the patient, and they typically include epinephrine, which rapidly counteracts the symptoms of severe allergic reactions. The prompt action of these medications is critical for stabilizing the patient and preventing further complications.

While antihistamines are often used to treat mild allergic reactions and can help with symptoms such as itching and hives, they are not suitable for addressing severe reactions like anaphylaxis as they take longer to take effect and do not reverse the reaction. Analgesics are pain relievers and do not play a role in allergic reactions, and vaccines are preventive measures against specific diseases rather than treatments for allergic reactions.
