Health experts in the UK have raised serious concerns over the excessive use of decongestant nasal sprays, warning that misuse can cause irreversible damage to the nasal passages.

The warning comes as cases of nasal spray dependency continue to rise, particularly during the cold and flu season.

Decongestant nasal sprays are widely available from chemists across the UK for less than four pounds. Many people rely on them for quick relief from blocked noses caused by colds, flu, or allergies.

However, health experts say the growing dependence on these sprays is becoming a serious public health issue. The easy availability and instant relief often lead users to ignore recommended usage limits.

Study reveals widespread lack of awareness

A recent study has found that nearly 60 per cent of users are unaware that nasal sprays should not be used for extended periods. As a result, many unknowingly expose themselves to health risks linked to prolonged use.

Experts warn that long-term use can trigger a condition known as rebound congestion. This occurs when nasal congestion returns more severely once the effect of the spray wears off.

Medical risks linked to prolonged use

The Royal Pharmaceutical Society has warned that extended use of decongestant sprays can inflame and swell the sensitive blood vessels inside the nose. This swelling can further block nasal passages instead of relieving them.

Over time, patients may become increasingly dependent on sprays simply to breathe normally.

This condition, medically referred to as rhinitis medicamentosa, can affect anyone who uses nasal sprays excessively. Symptoms include persistent nasal congestion, irritation, a runny nose, and frequent sneezing.

In severe cases, patients develop long-term swelling that does not respond to medication alone.

Health experts say that some patients with chronic nasal swelling are left with no option but to undergo surgery. These cases highlight the potential for lasting damage caused by misuse of over-the-counter nasal sprays.

According to estimates, around 5.5 million people in the UK are currently at risk of developing dependency on nasal sprays.
