HOW OUR PRODUCTS WORK

HOW A DECONGESTANT WORKS ON SINUS PRESSURE AND CONGESTION

All products from the makers of SUDAFED® contain a nasal decongestant, either pseudoephedrine, phenylephrine, or oxymetazoline. These medicines act on the nasal passages to narrow blood vessels that are causing nasal congestion. When the blood vessels in the nose and sinus region narrow, tissue shrinks to allow the normal flow of air and mucus.
