Runny Nose / Post-Nasal Drip Treatment

Chronic runny nose and post-nasal drip are among the most common ENT complaints in America — and among the most undertreated. Many patients cycle through antihistamines and nasal sprays for years without finding lasting relief. At The Center for Sinus, Allergy, & Sleep Wellness, Dr. David C. Brodner offers advanced, minimally invasive treatments that address the root cause of your symptoms rather than simply masking them.

If you have been living with constant nasal drainage in Boynton Beach, FL, relief is closer than you think. Call (561) 735-8750 to schedule your consultation today.

The glands in your nose and throat produce mucus constantly — normally between one and two quarts per day — to keep nasal passages moist, trap particles, and fight infection. You typically swallow this mucus without noticing it. Post-nasal drip occurs when your body produces more mucus than normal, or when the mucus becomes thicker than usual, causing you to feel it accumulating in the back of the throat.

A chronic runny nose (anterior rhinorrhea) involves excess mucus draining from the front of the nose rather than the throat. Both conditions are extremely common and can result from a wide variety of causes — from allergies and infections to structural issues and overactive nasal nerves.

Common triggers and underlying causes include:

• Allergies — Seasonal or environmental allergens trigger immune responses that increase mucus production. Allergy treatment is often a critical component of long-term relief.
• Non-allergic (vasomotor) rhinitis — Overactive nasal nerves cause excessive mucus production in response to temperature changes, humidity, strong odors, smoke, or spicy foods — without any allergic component.
• Chronic sinusitis — Blocked sinuses create a cycle of mucus buildup and drainage. Sinusitis therapy may be needed alongside rhinitis treatment.
• Deviated septum or nasal structural issues — Structural abnormalities that disrupt normal airflow can worsen mucus production and drainage.
• Medications — Certain blood pressure medications, NSAIDs, and overuse of nasal decongestant sprays can cause or worsen rhinitis.
• Hormonal changes — Pregnancy, thyroid disorders, and other hormonal shifts can increase nasal secretions.
• Acid reflux (LPR) — Laryngopharyngeal reflux can cause a persistent sensation of post-nasal drip and throat clearing.

Because runny nose and post-nasal drip can stem from multiple causes — often working together — effective treatment requires accurate diagnosis first. Dr. Brodner evaluates each patient thoroughly, using nasal endoscopy and allergy testing when appropriate, to identify what is driving your symptoms before recommending a treatment approach.

ClariFix® is an FDA-cleared, minimally invasive cryotherapy treatment that targets the overactive posterior nasal nerve — the nerve responsible for the excessive mucus secretion that causes chronic runny nose and congestion. Using a small probe that delivers controlled cooling to the back of the nasal cavity, ClariFix disrupts the overactive nerve signals that trigger excessive drip.

The procedure takes approximately one hour in our office, requires only a local anesthetic, and delivers lasting relief for approximately 80% of patients within two to six weeks. Most patients return to normal activities the same day.

Neuromark is another advanced in-office option for chronic rhinitis. This minimally invasive procedure uses low-power energy — rather than cold — to disrupt the overactive nasal nerves causing rhinitis symptoms. Like ClariFix, it treats rhinitis at its source, is performed in our office with no significant downtime, and is a low-risk option for patients who have not responded to medications.

Medical Management

For appropriate patients, medical management — including nasal steroid sprays, antihistamines, ipratropium nasal spray, or saline irrigation — remains part of the treatment toolkit. However, Dr. Brodner’s expertise in in-office procedural care means that patients who have failed medical management have meaningful alternatives available without resorting to traditional surgery.

For patients whose symptoms are driven by structural issues, Vivaer® Nasal Airway Remodeling or Coblation® Turbinate Reduction may be recommended to improve nasal airflow and reduce congestion contributing to post-nasal drip.

What is the difference between allergic and non-allergic rhinitis?

Allergic rhinitis is triggered by an immune response to specific allergens such as pollen, dust mites, or pet dander. Non-allergic (vasomotor) rhinitis involves overactive nasal nerves that cause mucus overproduction in response to environmental triggers — such as temperature changes, humidity, or strong odors — without any allergic mechanism.

Both types are treated at The Center for Sinus, Allergy, & Sleep Wellness, and they can coexist in the same patient. Proper testing helps Dr. Brodner determine which type — or combination — is at play.

How does ClariFix® work for chronic runny nose?

ClariFix® uses a small probe to deliver controlled cryotherapy (freezing) to the overactive posterior nasal nerve at the back of the nasal cavity. This disrupts the nerve signals responsible for excessive mucus production, reducing runny nose and congestion. Clinical studies show that 4 out of 5 patients experience lasting relief. The procedure is performed in our Boynton Beach office in approximately one hour with minimal discomfort.

Is ClariFix® or Neuromark right for me?

Both ClariFix® and Neuromark target the overactive nasal nerves causing rhinitis symptoms, but they use different energy modalities — cold and low-power electrical energy, respectively. Dr. Brodner evaluates each patient’s symptom profile, anatomy, and medical history to determine which approach is the best fit. A consultation at The Center for Sinus, Allergy, & Sleep Wellness is the best first step. Call (561) 735-8750 to schedule.

Can post-nasal drip cause a chronic cough or sore throat?

Yes. Post-nasal drip is one of the most common causes of chronic cough and persistent sore throat. When excess mucus drips down the back of the throat, it can irritate the larynx and trigger a reflex cough, or cause ongoing throat clearing and soreness. Treating the underlying rhinitis or sinusitis driving the post-nasal drip typically resolves these secondary symptoms.

How long does it take to see results from runny nose treatment?

Timeline varies by treatment type. Most patients who undergo ClariFix® or Neuromark begin to notice improvement within two to six weeks as the treated nasal nerve tissue heals. Patients on medical management may notice improvement within days to a few weeks, though medications typically require ongoing use to maintain symptom control.

Will I need to take medications long-term after ClariFix® or Neuromark?

Many patients who undergo ClariFix® or Neuromark experience significant enough improvement that their reliance on nasal sprays and other medications is substantially reduced or eliminated. Dr. Brodner reviews each patient’s medication needs individually after treatment and adjusts the plan based on their response.

Does The Center for Sinus, Allergy, & Sleep Wellness treat post-nasal drip caused by allergies?

Yes. When allergies are a primary driver of post-nasal drip, allergy testing and targeted allergy treatment are incorporated into the care plan alongside any procedural treatments. Addressing the allergic trigger — through immunotherapy or other means — provides more comprehensive and durable relief than treating the nasal symptoms alone.

Chronic runny nose and post-nasal drip are not conditions you have to simply manage indefinitely. The Center for Sinus, Allergy, & Sleep Wellness offers some of the most advanced, minimally invasive treatments available in South Florida for rhinitis and nasal drainage — including ClariFix® and Neuromark — delivered by Dr. Brodner, a nationally recognized leader in in-office ENT care.
