Unlike medicines that help relieve bothersome cold symptoms, First defence nasal spray works at the first signs of a cold by targeting the viruses to help stop the cold in its tracks before the symptoms get worse. When used at the first signs of a cold, First Defence nasal spray acts at the back of the nose directly where the cold virus takes hold and starts to develop(that’s why it’s a nasal spray). It traps, inactivates and helps your body naturally remove the cold virus, before it develops into a full blown cold.
