Individuals experiencing nasal congestion are being advised to restrict the use of nasal decongestant sprays to a maximum of seven days to avoid worsening their condition. This advisory comes in light of new findings that show nearly 60% of pharmacists believe the public remains largely unaware of the risks associated with prolonged use of these sprays.

While nasal sprays can provide short-term relief from congestion caused by colds, allergies, and sinusitis, using them for more than a week can lead to a condition known as rebound congestion, according to the Royal Pharmaceutical Society (RPS).

This preventable condition, medically referred to as rhinitis medicamentosa, can aggravate symptoms and potentially cause users to become dependent on the sprays for easier breathing. A survey conducted by the RPS, which included 300 pharmacists, found that 59% of them think the public is not well-informed about this risk. Furthermore, nearly three-quarters (74%) of pharmacists are calling for clearer labeling on packaging to highlight the seven-day usage limit.

Additionally, almost two-thirds (63%) of pharmacists have had to intervene when they suspected overuse of nasal sprays.

Professor Amira Guirguis, Chief Scientist at the RPS, stated, “Nasal decongestant sprays can be beneficial for short-term relief, but using them beyond seven days can significantly worsen congestion. Our research indicates that many people are not aware of this risk, which could lead them to continue using these sprays, unknowingly prolonging their symptoms.”

“We advocate for clearer warnings on packaging that are hard to miss and increased awareness of the seven-day limit,” added Professor Guirguis. “If your congestion persists beyond a week, consult your pharmacist. There are safe and effective alternative treatments available to help manage your symptoms.”

The RPS encouraged patients to consistently adhere to the guidance provided on nasal spray packaging and to consult pharmacists should congestion persist beyond seven days.
