First Defence nasal spray targets the area deep inside the nasal cavity where cold germs first take hold and multiply. First Defence is a Micro-Gel nasal spray based on plant extracts. It works by trapping cold causing germs and helping your body to remove them naturally. Start to use when at risk of catching a cold, or in the early stages before your cold has fully developed. For best results continue to use for 2 days after symptoms subside.
