Xylometazoline nasal is a decongestant. It works by constricting (shrinking) blood vessels (veins and arteries) in the body. The nasal formulation acts directly on the blood vessels in the nasal tissues. Constriction of the blood vessels in the nose and sinuses leads to a decrease in congestion.
Xylometazoline nasal is used to treat congestion associated with allergies, hay fever, sinus irritation, and the common cold.
