Get Instant Relief From The Misery Of Nasal Congestion Otrivine offer a range of nasal sprays & nasal drops for adults & children to help to alleviate the symptoms of colds, nasal congestion, allergic rhinitis, hay fever & sinusitis. These are designed to work up to 7 times faster than conventional decongestant tablets. All products in the Otrivine range contain a powerful decongestant agent Xylometazoline Hydrochloride to help reduce inflammation & swelling, clear blocked noses & sinuses within minutes & help to keep the nasal passages clear for up to 10 hours. The Xylometazoline helps to stimulate the alpha receptors in the blood vessel walls, this causes them to constrict & narrow, reducing the amount of blood flow to the affected area. This helps to slow down the amount of fluid (congestion) that is pushed out into the nasal lining, allowing you to breathe more freely throughout the day. How To Use Otrivine Children aged between 6 & 12 years old: 1 or 2 drops into each nostril once or twice a day.
