Which of the following is NOT a non-drug therapy option for allergic rhinitis?

Non-drug therapies for allergic rhinitis include lifestyle and environmental modifications aimed at reducing exposure to allergens. Keeping doors and windows closed helps prevent pollen and other outdoor allergens from entering the home environment. Vacuuming weekly is effective in removing dust, pet dander, and other indoor allergens, helping to maintain a cleaner living environment. Encasing bedding in dust-proof coverings can significantly reduce exposure to dust mites, which are a common trigger for allergic rhinitis.

Taking antihistamines, on the other hand, is a pharmacological approach to treating allergic rhinitis. Antihistamines work by blocking the action of histamine, a substance in the body that causes allergic symptoms. Therefore, this method is classified as a drug therapy, rather than a non-drug therapy. The distinction between these approaches is crucial in managing allergic rhinitis, as non-drug therapies often complement pharmacological treatments by reducing allergen exposure and overall symptom severity.
