People suffering from blocked noses are being urged to strictly limit their use of over-the-counter nasal decongestant sprays to just one week. A stark new warning from the Royal Pharmaceutical Society (RPS) states that exceeding this seven-day limit risks causing a more severe and persistent form of congestion.
The Hidden Danger of Overuse
New research underpinning the alert reveals a significant knowledge gap among the public. A survey of 300 pharmacists conducted by the RPS found that nearly six out of ten (59%) believe people do not understand the dangers associated with prolonged use of these sprays.
While decongestant sprays provide fast relief from stuffiness caused by colds, allergies, or sinusitis, they are designed for short-term use only. Professor Amira Guirguis, chief scientist at the RPS, explained the critical 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."
Understanding Rebound Congestion
The condition caused by overuse is known as rebound congestion or rhinitis medicamentosa. This is an avoidable problem where the nasal passages become dependent on the spray. Instead of clearing the blockage, continued use actually irritates the nasal lining, making the original symptoms deteriorate.
Sufferers then find themselves trapped in a cycle, needing to use the spray more frequently just to achieve normal breathing. The RPS survey indicated that almost two-thirds (63%) of pharmacists have intervened when they suspected a customer was overusing these products.
Calls for Clearer Warnings and Public Awareness
The findings have prompted calls for much clearer information on product packaging. A substantial 74% of the pharmacists surveyed felt that the labelling on nasal spray packaging needs to more prominently highlight the seven-day restriction to prevent misuse.
"We'd like to see clearer warnings on the packaging which you can't miss and greater awareness of the seven-day limit," Professor Guirguis stated. She emphasised the importance of seeking professional advice if symptoms persist, adding: "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."
The RPS's final advice is clear: patients should always follow the instructions on nasal spray packaging meticulously and consult their pharmacist if nasal congestion continues beyond the recommended seven-day period.
