The use of antihistamines is appropriate for managing less severe reactions, particularly those related to allergies or mild hypersensitivity such as itching, rashes, and other non-life-threatening symptoms. Antihistamines work by blocking histamine receptors, which reduces the symptoms associated with allergic reactions and can provide quick relief for conditions like urticaria or allergic rhinitis.

Other options serve different purposes: antibiotics are primarily used to fight bacterial infections, analgesics are intended for pain relief and do not specifically address allergic reactions, while antivirals target viral infections. Therefore, while these medications are essential in their respective areas, they are not indicated for managing mild allergic or hypersensitive reactions. Antihistamines, by contrast, specifically address the symptoms of these milder reactions effectively, making them the suitable choice in this context.
