Additionally, decongestants such as pseudoephedrine can reduce nasal congestion by causing vasoconstriction in the nasal passages, leading to reduced swelling and improved airflow.

Instead, the focus is on managing symptoms to improve patient comfort and quality of life during the course of the illness.

The other treatment options are not suitable for viral upper respiratory infections; for example, leukotriene receptor antagonists are used primarily in asthma and allergic rhinitis, macrolide antibiotics target bacterial infections and would not be effective against viruses, and corticosteroids, while they can reduce inflammation, are not standard for treating uncomplicated viral upper respiratory
