Colds, sinusitis and hay fever – these are common ailments that cause blocked noses in millions of people around the world at any one time.
Of these three ailments, the cold is the most widespread and frequently experienced, which is why we often call it ‘the common cold’.1
All three of these conditions share similar symptoms such as a runny nose, a blocked or stuffy nose and sneezing.1

A blocked nose occurs when an infection or allergy causes the blood vessels in the nasal cavity to swell and for excessive fluid or mucus to be produced. This gives rise to a ‘stuffy feeling’.6

The sinuses and entire nasal cavity are lined with a thick layer of tissue called the nasal mucosa (also known as the mucocilliary layer or apparatus). This mucous membrane is responsible for transporting mucus. It provides an important defense mechanism against inhaled organisms and pollutants.3,4,5

Over-the-counter (OTC) relief for congestion

OTC medicines, such as decongestants, may help relieve a blocked nose and can make breathing more comfortable. These medicines help to narrow the blood vessels in the lining of the nose and in this way help to relieve nasal stuffiness.6
Decongestant nasal sprays and drops work quickly as they are applied directly to the nasal tissue that is affected. However, they should not be used for more than 3 days as they can make congestion worse.

Saline is salt water and is thought to work by improving the function of the nasal mucosa or mucociliary apparatus.9 Saline sprays can be used to relieve blocked noses, clear excess mucus from the nose and improve breathing.11
Saline sprays are mainly available in 2 forms, namely isotonic and hypertonic solutions.10
The Isotonic solutions have the same salt concentration as the cells that line the nasal cavity whereas hypertonic solutions have a higher salt concentration.10
