When the cold weather arrives, along with respiratory viruses or allergy season, many people turn to decongestant nasal sprays as a quick solution for a stuffy nose. A couple of sprays and the feeling of relief is usually almost immediate, making these products a staple in the family medicine cabinet.
The problem arises when this occasional remedy becomes a daily and prolonged habit , without consulting a healthcare professional. The Spanish Society of Otolaryngology and Head and Neck Surgery (SEORL-CCC) has issued a clear warning: the continued use of these sprays without medical supervision can have the opposite effect and contribute to chronic congestion.
How do decongestant nasal sprays work?
Topical nasal decongestants usually contain drugs with a vasoconstrictor effect . That is, they work by reducing blood flow to the nasal mucosa. By decreasing blood flow, the mucosa becomes less inflamed and the feeling of congestion disappears quickly, which explains why the relief is so fast and appealing.
This mechanism of action allows the person to breathe much better for a few days and feel that the spray "fixes everything." However, specialists remind us that these are medications designed for very limited use , intended as occasional support for colds, flu, or acute episodes of allergic rhinitis.
The SEORL-CCC (Spanish Society of Otorhinolaryngology and Head and Neck Surgery) insists that the use of these products should not exceed five to seven days . This is, in general, the recommended guideline to avoid subsequent problems. Exceeding this time limit turns a useful remedy into a potential source of new symptoms.
Rhinitis medicamentosa: when the spray causes more congestion
Prolonged use of vasoconstrictor nasal sprays can trigger rhinitis medicamentosa , a condition characterized by a rebound effect : once the medication wears off, the nasal mucosa becomes even more congested than before, leading the patient to return to the spray seeking the same relief.
As the days go by, tolerance to the medication also develops . This means that the same dose stops being effective, and the person needs to apply the spray more frequently or in larger quantities to notice any improvement. It's a vicious cycle that leads to a progressive worsening of the condition.
Otolaryngologists describe this process almost as an "addiction" to the decongestant: the patient reaches a point where they feel they cannot breathe without using the spray , and if they try to stop, the congestion flares up again due to the rebound effect. This dependence can last for weeks or even months if left untreated.
Rhinitis medicamentosa is widely described in the scientific literature and, according to specialists, is a frequent reason for consultation in otolaryngology units in Spain and other European countries, especially in people who have self-medicated for long periods.
Risks of abuse: beyond the nose
The problem with the overuse of decongestant nasal sprays is not limited to the discomfort of a stuffy nose. The SEORL-CCC (Spanish Society of Otorhinolaryngology and Head and Neck Surgery) warns that excessive use increases the likelihood of systemic and local adverse effects , which are practically nonexistent when the product is used as directed.
Common side effects include tachycardia (increased heart rate) and elevated blood pressure . In people with hypertension, heart problems, or other risk factors, these changes can be particularly serious, making use without medical supervision even less advisable.
At a local level, prolonged vasoconstriction can lead to a chronic decrease in blood flow to the nasal mucosa . This promotes irritation and direct damage to the tissues, resulting in intense dryness, small wounds, scabs, and a stinging or burning sensation inside the nose.
In extreme cases of prolonged abuse, even nasal septum perforations have been reported . Although these complications are very rare when the correct dosage is followed, their mere possibility reinforces the message of not trivializing these drugs or treating them as if they were harmless.
Nasal congestion does not always have the same cause
Another point emphasized by otolaryngologists is that nasal congestion is a symptom, not a disease in itself . In other words, it can be caused by multiple factors, and not all of them benefit from the use of topical vasoconstrictors. In fact, they are often ineffective or even counterproductive if used as the sole treatment.
Common causes of nasal congestion include allergic rhinitis , sinusitis , turbinate hypertrophy , and a deviated septum , among others. In these cases, the obstruction is usually related to inflammation, anatomical abnormalities, or chronic conditions that require specific treatment , not just temporarily "opening the nose."
In many patients, the sensation of not being able to breathe properly is not necessarily due to insufficient physical space in the nasal passages, but rather to inflammation of the nasal mucosa . In these cases, treatment aimed at controlling this inflammation (for example, with allergy medications or other local anti-inflammatories) may be more helpful than repeated use of vasoconstrictors.
When decongestant sprays are used indiscriminately as the sole solution, there is a risk of masking the underlying problem . This can delay the diagnosis of the disease causing the congestion and postpone the start of appropriate treatment. Ultimately, the patient not only continues to suffer from their original condition but also develops rhinitis medicamentosa, which is difficult to manage.
Self-medication and easy access: the perfect cocktail for abuse
Daily clinical practice shows that self-medication with nasal sprays is especially common during the winter months, when colds and respiratory infections increase, and also in spring, with the peak of allergy season. The fact that many of these products are readily available in pharmacies , sometimes without a prescription, encourages their use without professional advice.
Many users are unaware that these medications have clear time limits for use and are not a harmless solution to be applied indiscriminately. Because they are perceived as commonplace and seemingly safe, their use tends to be prolonged beyond the recommended days, increasing the risk of dependence and the development of rhinitis medicamentosa.
Experts point out that, often, people start using them "just for a few days" during a cold, but then continue applying them at the first sign of congestion. Before they know it, they've been using them almost daily for weeks or months .
The SEORL-CCC (Spanish Society of Otorhinolaryngology and Head and Neck Surgery) emphasizes the need to better inform the public about the risks involved in this type of nasal self-medication, and that primary care professionals and community pharmacies should take advantage of direct contact with patients to remind them of the appropriate usage guidelines.
The experts' perspective: do not normalize persistent congestion
Otolaryngologists emphasize that prolonged nasal congestion requiring almost constant use of nasal spray should not be considered normal . According to the SEORL-CCC (Spanish Society of Otolaryngology and Head and Neck Surgery), when someone needs these products continuously to breathe comfortably, there is most likely an underlying cause that requires investigation.
The president of the scientific society, SerafÃn Sánchez , summarizes the experts' position by pointing out that persistent nasal congestion should be a reason for consultation and not something that can be fixed indefinitely with a single spray of nasal spray. The phrase many specialists repeat is that breathing well is key to quality of life and deserves a proper medical evaluation.
The general recommendation is clear: if nasal congestion persists, recurs repeatedly, or only improves while using decongestant spray , it's advisable to make an appointment with an ENT specialist. Delaying a consultation is often associated with prolonged and inappropriate use of these medications, with a consequent increase in the risk of complications.
Furthermore, ignoring symptoms for months can allow certain nasal conditions to become chronic , requiring more complex or prolonged treatments than would have been necessary with early intervention.
What an ENT specialist can offer: diagnosis and alternatives
An evaluation by an ear, nose, and throat (ENT) specialist allows for the identification of the specific cause of congestion through a detailed examination of the nose and sinuses. Depending on the findings, the ENT specialist can propose different treatment strategies tailored to each individual case.
Options include preventative measures and lifestyle changes , such as improving nasal hygiene with saline washes, avoiding environmental irritants (tobacco, pollution, very dry air) or adjusting certain factors in the home environment to reduce allergy triggers.
Many patients are treated with specific medications , such as topical nasal corticosteroids, antihistamines, or other drugs aimed at treating the underlying inflammation or disease causing the congestion. When properly prescribed and monitored, these treatments generally have a more suitable safety profile for long-term use than vasoconstrictors.
In certain cases, when anatomical abnormalities such as a marked septal deviation or significant turbinate hypertrophy are present, the specialist may consider a surgical approach . These types of procedures aim to correct the physical cause of the obstruction to improve nasal breathing in a stable manner.
Beyond treatment, experts emphasize that early diagnosis plays a fundamental role: it helps prevent the underlying pathology from lasting for years and reduces the likelihood that the patient will resort to potentially harmful quick fixes on their own, such as the chronic use of decongestant sprays.
Overall, the messages from the SEORL-CCC (Spanish Society of Otorhinolaryngology and Head and Neck Surgery) and European otolaryngologists point in the same direction: use decongestant nasal sprays for only a few days , avoid making them a permanent part of your routine, and consult a specialist if congestion persists or recurs frequently. Turning occasional relief into an uncontrolled routine not only fails to solve the problem but can also lead to new issues, from rhinitis medicamentosa (drug-induced rhinitis) to more serious complications affecting the nasal mucosa and overall health.
