It’s a universal experience – the sudden drip, drip, drip of a runny nose. Whether it’s brought on by a common cold, the flu, seasonal allergies, or even COVID-19, most of us have reached for a tissue to combat nasal drainage. But what happens when the runny nose doesn’t stop? What if you find yourself constantly reaching for tissues, seemingly without any relief? Perhaps you’ve even noticed patterns, like your nose starting to run the moment you sit down to eat. Is this just a quirk, or could there be something more to it?
“It’s important to recognize that a persistent runny nose is often accompanied by a range of other symptoms,” explains Dr. Mas Takashima, a leading ENT (Ear, Nose, and Throat) doctor at Houston Methodist, specializing in nasal and sinus disorders. “Chronic rhinitis, as we call it, isn’t just about nasal discharge. Patients often experience sneezing, nasal congestion, coughing, and an irritating itchiness within the nose as well.”
While a chronic runny nose might not signal a life-threatening condition, its impact on daily life can be significant. The constant need to blow your nose, the discomfort, and even the social awkwardness it can cause are all valid reasons to seek answers. If you’re tired of constantly battling a runny nose, you’re in the right place to learn more.
When Does a Runny Nose Become Chronic?
To understand chronic rhinitis, it’s helpful to first understand the normal nasal response. Rhinitis, in its simplest terms, is inflammation or irritation of the nasal passages. When this occurs, your nose naturally produces more mucus. This mucus is the body’s defense mechanism, designed to trap and flush out irritants. This is why a runny nose is a common symptom when you’re fighting off a cold or dealing with allergens.
Fortunately, most cases of rhinitis are acute, meaning they are temporary and resolve as the underlying cause diminishes. As the inflammation subsides, so does the runny nose. Chronic rhinitis, however, is a different story. It develops when the nasal passages are continuously triggered, irritated, or inflamed. This persistent state leads to a runny nose that either never fully disappears or is a constant background nuisance. Dr. Takashima emphasizes the significant impact this can have on quality of life.
“Chronic rhinitis is characterized by symptoms that persist for months, even years,” Dr. Takashima clarifies. “This is despite consistent use of medication for at least a month aimed at treating the issue. These are the individuals who always have tissues on hand, constantly blowing their nose. The condition can become so bothersome that some people feel self-conscious about being in public, especially in today’s world where coughing, throat clearing, and nose-blowing can be misinterpreted due to concerns about illnesses like COVID-19.”
Unpacking the Causes of a Persistent Runny Nose
The triggers for acute rhinitis are generally well-known: common colds, influenza, COVID-19 infections, and short-lived seasonal allergies. However, identifying the root cause of chronic rhinitis can be more complex. The most prevalent culprits include:
-
Allergic Rhinitis: This occurs when your immune system overreacts to allergens like pollen, dust mites, mold, or pet dander. This overreaction causes inflammation within the nasal passages, leading to increased mucus production.
-
Acid Reflux (Laryngopharyngeal Reflux or LPR): While often associated with heartburn, acid reflux can also reach the upper airways and nasal passages. When stomach acid travels up to the nose, it can irritate the sensitive nasal linings, triggering inflammation and a runny nose.
-
Vasomotor Rhinitis (Nonallergic Rhinitis): This category of rhinitis is triggered by everyday, non-allergenic factors. In vasomotor rhinitis, the brain and nose exhibit an exaggerated response to common environmental stimuli like air pollution, changes in temperature (especially cold air), strong odors, spicy foods, or even exercise. This overreaction prompts the nose to produce excessive mucus, even when it’s not truly needed to clear out irritants.

“Allergic rhinitis stands out as a particularly frequent cause of persistent runny noses, especially in humid climates,” notes Dr. Takashima. “High humidity, common in many regions, promotes the growth of mold spores, and dust mites thrive as well – both potent allergens.”
Vasomotor rhinitis remains somewhat enigmatic in terms of its exact causes. However, Dr. Takashima points out that its occurrence tends to increase with age, suggesting age-related changes in nasal sensitivity or neurological responses may play a role.
Beyond these common causes, other less frequent factors can contribute to a chronic runny nose. Certain medications, for example, can have a runny nose as a side effect. Ironically, overuse of nasal decongestant sprays can actually lead to a rebound effect, causing a persistent runny nose that becomes worse than the original congestion.
“It’s also important to remember that viral illnesses can sometimes leave behind a lingering runny nose or cough,” Dr. Takashima adds. “These symptoms are often the last to resolve after the infection has cleared. We’re seeing this more frequently now in the aftermath of COVID-19, where individuals experience a persistent runny nose or cough for weeks or even months after recovering from the initial infection.”
Dr. Takashima stresses that pinpointing the specific cause is the crucial first step in effectively addressing a constant runny nose. “Treatment strategies are heavily dependent on identifying the underlying etiology of the rhinitis,” he explains.
Strategies to Stop a Constant Runny Nose
The initial step in managing a persistent runny nose is to consult your primary care physician. They can initiate treatment with common and often effective therapies, such as nasal sprays (corticosteroid or saline), oral antihistamines, and sinus irrigation.
“For many cases, especially those related to allergic rhinitis, these basic treatments can provide significant relief,” Dr. Takashima states. “Sinus irrigation, or nasal rinsing, is a particularly beneficial approach. It physically washes away irritants like allergens and environmental pollutants from the nasal passages.”
If these initial, frontline treatments fail to provide adequate relief, your primary care doctor can refer you to an ENT specialist, specifically a rhinologist, who specializes in nasal and sinus disorders.
“At this stage, we delve deeper into identifying the specific underlying causes of your rhinitis,” explains Dr. Takashima.
The ENT specialist will conduct a thorough assessment, including taking a detailed history of your symptoms and any other relevant health conditions. This information helps narrow down the possible diagnoses. For example, Dr. Takashima notes that if a patient reports their nose runs primarily when eating or exercising, it strongly suggests nonallergic rhinitis as the likely cause.
“In such cases of suspected nonallergic rhinitis, we might immediately try an ipratropium nasal spray,” Dr. Takashima illustrates. “This medication works to reduce the amount of mucus your nose produces, and we can quickly assess if it improves symptoms.”
If allergic rhinitis is suspected, the ENT specialist may recommend allergy testing to identify specific triggers. Based on the results, allergy shots (immunotherapy) or sublingual immunotherapy (allergy drops) may be recommended to desensitize you to those allergens. If acid reflux is considered a contributing factor, medications to manage reflux may be prescribed.
“We systematically explore these treatment options to see if symptoms improve,” says Dr. Takashima. “From there, we tailor a management plan. However, sometimes, despite trying all these approaches, a persistent runny nose continues. This is when we begin to consider procedural interventions.”
When Treatment Isn’t Enough: Exploring Advanced Options
When a chronic runny nose proves resistant to conventional treatments and significantly diminishes a person’s quality of life, more advanced procedures, and in some cases, even surgery, might be considered.
“We always prioritize non-invasive treatment strategies first, but when necessary, there are minimally invasive procedures that can be remarkably effective,” Dr. Takashima assures.
Cryotherapy and radiofrequency therapy are two such in-office procedures specifically designed to treat nonallergic rhinitis.

“In both procedures, a small, specialized device is carefully inserted into the nose and positioned near the nerve that controls mucus production,” Dr. Takashima explains. “Cryotherapy uses extremely cold temperatures, while radiofrequency therapy utilizes radiofrequency energy to target this nerve. The treatment effectively reduces the nerve’s activity, preventing the brain from inappropriately signaling the nose to produce excessive mucus.”
Both cryotherapy and radiofrequency therapy are characterized by minimal discomfort, short procedure times, and a strong safety profile. Dr. Takashima notes that their effectiveness is comparable, with approximately 65% of patients experiencing a significant reduction – around 70% – in nasal drainage.
“Our research team has dedicated considerable effort to understanding the underlying mechanisms of chronic rhinitis and evaluating the effectiveness of these procedures,” Dr. Takashima highlights. “Our findings indicate that these in-office procedures are not only beneficial for nonallergic rhinitis but can also alleviate symptoms of allergic rhinitis.”
This broader applicability means that individuals with severe allergic rhinitis, who might otherwise face years of allergy shots, could potentially opt for one of these procedures as an alternative.
In rare cases, when in-office procedures are not successful, surgery may be considered as a last resort for chronic rhinitis treatment. Surgical intervention involves physically cutting the nerve supply that triggers excessive mucus production.
“Surgery is an option we discuss if in-office procedures prove ineffective,” Dr. Takashima concludes. “We always prioritize exhausting all other treatment avenues, from non-invasive medications to less invasive procedures, before recommending any surgical options. However, surgery can be a highly effective treatment modality when other approaches have not provided sufficient relief.”
