Lemsip First Action Nasal Spray helps stop a cold before it takes hold by targeting viruses at the first signs of infection. Its clinically proven formula forms a protective barrier in the nose to trap and remove cold-causing viruses.
Lemsip First Action Nasal Spray is a clinically proven cold defence spray that helps stop viruses before they can cause a full cold or flu infection.
This innovative medical device contains Carragelose, a natural ingredient derived from red seaweed, which helps trap and neutralise cold viruses in the nasal passages.
By forming a protective barrier inside your nose, Lemsip First Action works at the first signs of a cold to reduce the risk of symptoms developing further.
Clinically proven to help prevent colds from developing
Traps and inactivates viruses before they infect healthy cells
Helps reduce the duration and severity of cold symptoms
Drug-free, non-drowsy formula suitable for adults and children over 1 year
Provides fast, targeted action at the first signs of a cold
Gentle enough for daily use
Lemsip First Action gets to work in three simple steps:
Shield – When sprayed into the nose, Carragelose forms a protective film on the nasal lining.
Trap – This barrier traps cold and flu viruses, preventing them from attaching to and infecting healthy cells.
Remove – The trapped viruses are then naturally cleared through the body’s nasal processes.
By acting directly in the nasal cavity – the main entry point for cold viruses – it helps block infection early, supporting your body’s natural defences.
Use at the first signs of a cold, such as:
Tickly or sore throat
Runny or stuffy nose
Sneezing
Mild headache or fatigue
It can also be used proactively if you’ve been in close contact with someone who has a cold, or when cold viruses are circulating in your environment.
Always read the patient information leaflet before use.
