Health experts are warning of a growing problem with nasal decongestant spray addiction, which can cause permanent damage to the airways.
The sprays, sold at high street chemists for under £4, are a common remedy for blocked noses, particularly during cold and flu season. However, new research shows nearly 60% of users are unaware they should not use the sprays long-term, putting them at risk of rebound congestion.
Experts at the Royal Pharmaceutical Society (RPS) explain that overuse irritates delicate blood vessels in the nose, causing swelling and worsening congestion. This cycle, medically known as rhinitis medicamentosa, can lead to runny nose, sneezing, and chronic nasal irritation. In severe cases, patients may require surgery to correct tissue damage, which can affect breathing and facial structure.
A study by ITV and Ipsos found that over 20% of adults using nasal sprays have done so for more than a week—equivalent to about 5.5 million people in the UK—putting them at risk of dependency.
Professor Amira Guirguis, chief scientist at RPS, called for clearer packaging warnings about the seven-day usage limit and the potential dangers of overuse. Some affected patients have even suggested making these medications prescription-only to allow doctors to monitor use.
Charlotte Johnstone, 30, is one patient who has struggled with nasal spray addiction since age seven. At the peak of her 23-year struggle, she was using sprays up to eight times a day. She describes her reliance as “addiction,” causing anxiety and fear of being without access to the medication.
While most users can successfully wean themselves off sprays without long-term damage, some may require steroid-based sprays to manage symptoms during recovery—a process many find daunting.
The RPS emphasizes that rebound congestion only occurs with sprays containing oxymetazoline or xylometazoline, not saline or steroid-based alternatives. The consumer healthcare association PAGB notes that packaging and information leaflets already advise against continuous use beyond seven days.
Experts urge users to be aware of the risks and adhere to recommended usage limits to avoid long-term harm.
