Researchers from the German Society of Oto-Rhino-Laryngology caution against overuse of nasal sprays. While highly effective for congestion relief, excessive use can lead to serious side effects.
When nasal congestion strikes, a nasal spray often brings quick relief. However, its benefits come with caveats. A study published on November 2, 2020, by the German Society of Oto-Rhino-Laryngology highlights these positives while issuing a clear warning. The spray constricts blood vessels in the nasal turbinates, reducing swelling and freeing up space for better airflow.
“Nasal sprays provide a pleasant clearing sensation that we can become accustomed to,” says lead author Heino Stöver, MD.
This enjoyable release can lead mucous membranes to crave regular doses, creating a vicious cycle. Effects diminish with frequent use, prompting more sprays and worsening congestion. Over time, this may result in chronic nasal obstruction, impairing mucous membrane hydration.
Heino Stöver speaks from experience, having overused nasal sprays multiple times daily for two years in his youth when risks were less understood. Today, experts advise limiting use to no more than two consecutive weeks. Unlike psychoactive substances, these sprays don't cause true addiction—but tolerance develops rapidly, leading to overuse of 3–8 times daily.
Dried-out mucous membranes lose their protective function against germs, forming scabs that invite infections. In severe cases, this progresses to atrophic rhinitis, characterized by foul nasal odors.
Study authors recommend gradual tapering and tracking usage in a daily log. Safer options include sea salt sprays. Consult a physician for persistent issues or reduced efficacy.
