Nasal congestion or ‘stuffy nose’ refers to blockage of nasal passage causing obstruction of airflow and feeling of facial fullness.
Nasal congestion is often the most predominant symptom in upper respiratory tract disorders like cold & flu, allergic rhinitis
Allergic rhinitis is a type of inflammation that affects the lining of the nose and upper respiratory passages which occurs when the immune system reacts to allergens in the air like dust, pollen, irritants, etc. Signs and symptoms include a runny or stuffy nose, sneezing, red, itchy, and watery eyes, and swelling around the eyes.
Sinusitis is a common inflammation of the paranasal sinuses. Sinus infections often follow a cold and can cause pain and pressure in forehead, eye and jaw area.
Nasal mucosa is a thin lining that lines the nose. It has a large number of blood vessels. When it gets inflamed due to allergy, the blood vessels enlarge, and hence the nasal mucosa becomes thicker. This leads to a sensation of nasal block.
Oxymetazoline, the active ingredient of Naselin, works by constricting the dilated blood vessels thus reducing the thickness of the nasal mucosa back to normal and easing the flow of the air through the nasal cavity.
