Which type of drug would not typically be used for treating allergic symptoms?

Antivirals are designed to combat viral infections and are not intended for the treatment of allergic symptoms. Allergic reactions occur when the immune system responds to a substance (allergen) as if it were harmful, leading to symptoms such as sneezing, itching, and swelling. Antihistamines work by blocking the action of histamine, a chemical that contributes to allergic symptoms, while corticosteroids can reduce inflammation caused by allergies. Decongestants help relieve nasal congestion associated with allergic rhinitis. In contrast, antivirals do not target the mechanisms involved in allergic responses and, therefore, would not be effective in treating allergic symptoms.
