People suffering from blocked noses are being urged to strictly limit their use of over-the-counter nasal decongestant sprays to a maximum of seven days. A stark new warning from the Royal Pharmaceutical Society (RPS) states that exceeding this 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 these sprays provide fast relief from stuffiness caused by colds, allergies, and sinusitis, using them for more than a week can trigger a condition known as rebound congestion or rhinitis medicamentosa. This avoidable problem causes the original symptoms to deteriorate, creating a cycle where users become dependent on the spray simply to breathe normally.
Pharmacists Call for Clearer Warnings
The survey also highlighted concerns about product labelling. Almost three-quarters (74%) of the pharmacists polled felt that packaging should more prominently display the seven-day usage restriction. Furthermore, 63% reported having intervened when they suspected a customer was overusing these medications.
Professor Amira Guirguis, Chief Scientist at the RPS, emphasised the need for greater awareness. "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 explained. "Our research shows that many people are unaware of this risk, which means they may continue using these sprays without realising they could be prolonging their symptoms."
Seeking Safe Alternatives
The RPS is advocating for unambiguous warnings on packaging and better public understanding of the critical one-week limit. Professor Guirguis advised, "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 society's final guidance is clear: patients should carefully follow the instructions on nasal spray packaging and consult a pharmacist if nasal congestion persists beyond the seven-day timeframe. This professional advice can help break the cycle of rebound congestion and identify more suitable long-term treatments.
