Nasal Spray Kills Cold VirusBy
Nasal sprays can help reduce sinus congestion, but a recent study showed to have an anti-viral effect, especially against the rhinovirus, the virus responsible for the common cold. The effective compound in several over-the-counter nasal sprays is Oxymetazoline which may kill the virus that causes colds.
In this volunteered study, each person was given either a nasal spray that contained oxymetazoline or a saline solution. The participant that received the saline solutions showed no significant reduction in virus levels. While participants receiving the nasal sprays containing oxymetazoline showed a reduction in the rhino-virus levels.
Many of the popular brands such as Afrin, Dristan 12 Hour Nasal Spray, Duramist Plus and Vicks Sinex 12 Hour Nasal Spray, contain oxymetazoline.
The study cautioned that not only do these sprays reduce virus levels and provide temporary relief of nasal congestion, continual or long term use (5 or more consecutive days) could lead nasal tissue damage and chronic congestion. So use wisely.
