The National Health Service has issued a stark warning to millions of Britons who rely on common over-the-counter nasal sprays, cautioning that incorrect use can lead to a cycle of dependency and worsen the very symptoms they are meant to treat.
The Hidden Danger of Rebound Congestion
While these sprays offer quick relief from the stuffiness of colds, flu, and allergies, using them for more than seven consecutive days can trigger a condition known as 'rebound congestion'. This paradoxical effect causes nasal passages to become even more blocked once the spray wears off, mimicking the original symptoms.
Professor Amira Guirguis, Chief Scientist at the Royal Pharmaceutical Society (RPS), explained the risk. "Nasal decongestant sprays can be helpful for short-term relief but using them for longer than seven days can make your congestion significantly worse," she said. The danger lies in the response: people often reach for the spray again to treat this new congestion, unknowingly perpetuating a harmful cycle.
Which Sprays Pose a Risk and Recognising Overuse
It is crucial to note that not all nasal sprays carry this risk. The problem is specifically linked to sprays containing the active ingredients xylometazoline and oxymetazoline. Other types, such as steroid-based or simple saline (salt water) sprays, are generally considered safe for longer-term use.
Alarmingly, data from the RPS indicates that nearly 60% of pharmacists believe patients are unaware of these dangers. Signs that you may be overusing a decongestant nasal spray include:
- Needing to use the spray more frequently than directed.
- Experiencing worse congestion when you try to stop.
- Routinely buying multiple bottles.
- Exceeding the recommended dose on the packaging.
Official Guidance and Safer Alternatives
The NHS provides clear guidance: decongestant sprays should be used no more than between one and four times a day, and for a maximum of one week. It urges anyone with symptoms persisting beyond this period to speak to a GP or pharmacist, rather than continuing with the spray.
Professor Guirguis and the RPS are calling for clearer warnings on packaging to prevent misuse. "If your congestion lasts more than a week, speak to your pharmacist. There are safe and effective alternative options to help you manage your symptoms," she advised. The key takeaway is to always read the patient information leaflet and seek professional advice for ongoing issues, breaking the dependency cycle before it starts.
