Vicks First Defence attacks the cold by physical rather than pharmacological means, supplementing the body's natural ability to disarm and remove the cold virus before it takes a strong hold in the nose and throat. When sprayed into the back of the nasal passage, the viscous gel coats the virus so it can't dock to the body's cells, disarms it by creating an environment in which it cannot flourish and then flushes out the viruses, aided by mucus secretions. The average incubation period for a common cold is usually around two days. Research shows this incubation period offers an opportunity to inhibit the virus before it takes hold. As a result, Vicks First Defence is most effective when used at the early signs of a cold - a tickly sore throat and sneezing are the most common.
For optimum results, Vicks First Defence should continue to be used for two days after the symptoms have subsided. It can also be taken when there is an increased risk of catching a cold, for example on public transport, in the office or when a partner or family member already has a cold.

Adults and children (12 years and older): without tilting head, apply 2 - 3 sprays per nostril 4 times a day and avoid inhaling deeply.
