Pharmacists are warning the public to limit use of nasal decongestant sprays to seven days, cautioning that longer use can worsen congestion. A survey by the Royal Pharmaceutical Society (RPS) found that almost six in 10 pharmacists believe patients are unaware of the risks associated with prolonged use.
Decongestant sprays provide short-term relief for stuffiness caused by colds, allergies, and sinusitis. However, using them for more than a week can lead to rebound congestion, also known as rhinitis medicamentosa, a preventable condition that causes symptoms to intensify and can lead to dependence on the spray.
The RPS survey of 300 pharmacists revealed that 59% think the public is unaware of this risk, while 74% said packaging should more clearly state the seven-day limit. Nearly two-thirds (63%) reported intervening in cases of suspected overuse.
Professor Amira Guirguis, chief scientist at the RPS, stated: “Nasal decongestant sprays can be helpful for short-term relief, but using them for longer than seven days can make your congestion significantly worse. 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.”
The RPS is calling for clearer warnings on packaging and greater awareness of the seven-day limit. Patients whose congestion persists beyond a week are advised to consult their pharmacist for safe alternative treatments.
A spokesperson for PAGB, the consumer healthcare association, defended current packaging, noting that product packs already highlight the importance of not using sprays for more than seven days. They urged the public to follow instructions and seek pharmacist advice if needed.
