Vicks® Sinex® is a brand of topical nasal decongestant spray. The active ingredient contained in the Sinex® nasal spray is Oxymetazoline which acts to relieve blocked nasal passages. The recommended dosage is 1-2 sprays in each nostril every 6-8 hours. Excessive use of this product could lead to a dependancy on it whereby the nasal passages block without use of Oxymetazoline again. Thus it is not recommended that Sinex® be used for more than 7 days. Extra ingredients include camphor, eucalyptol, and menthol, which give Sinex® Nasal Spray products the characteristic aroma of Vicks® products. Sinex® products also contain the antibacterial Benzalkonium Chloride.

Sinex® Nasal Spray may contain Phenylephrine as an active ingredient in other non-UK countries.
