What Is Chronic Cough?
Chronic cough is defined as a cough that lasts 8 weeks or longer in adults, or 4 weeks or longer in children. Unlike an acute cough tied to a cold or infection, chronic cough is a symptom, not a diagnosis, and the real work of treatment is figuring out what is causing it.
In the vast majority of adult chronic cough cases, the cause falls into one of three categories, often called the Triple Threat:
- Upper Airway Cough Syndrome (UACS): post-nasal drip from allergic or non-allergic rhinitis, the most common cause overall
- Cough-Variant Asthma: a type of asthma where a chronic dry cough is the only symptom
- Gastroesophageal Reflux Disease (GERD): stomach acid irritating the throat and airway, sometimes without obvious heartburn
More than one of these can be at work at the same time, which is why chronic cough often gets misdiagnosed and mistreated. In South Florida, year-round allergen exposure and humidity make UACS and cough-variant asthma especially common in Atlantis and Boynton Beach.
At Florida Allergy & Asthma Associates, our team takes a systematic approach to chronic cough: identify the driver (or drivers), treat what we can in-office, and coordinate care for anything outside our scope.
Chronic Cough Symptoms & Warning Signs
- A cough lasting 8 weeks or longer in an adult (or 4 weeks or longer in a child)
- Post-nasal drip, the sensation of liquid running down the back of your throat
- Hoarseness, voice changes, or a constant need to clear your throat
- Heartburn, sour taste in the mouth, or symptoms that worsen after meals
- Shortness of breath or wheezing during exertion
- Nocturnal coughing that flares specifically when you lie down
- Cough that is dry and non-productive versus productive with mucus (color and volume matter)
- Fatigue, disrupted sleep, or social embarrassment from persistent coughing
Common Causes & Florida-Specific Triggers
- Upper Airway Cough Syndrome (UACS): the most common cause in adults, driven by year-round allergic rhinitis, chronic sinusitis, or non-allergic rhinitis. Highly relevant in South Florida given continuous allergen exposure.
- Cough-variant asthma: a form of asthma where a chronic dry cough is the only symptom, often triggered by mold, humidity, or exercise. Frequently missed because there is no wheezing.
- Gastroesophageal Reflux Disease (GERD): acid rising from the stomach can irritate the throat and airway, causing a reflex cough even in patients without obvious heartburn
- Environmental irritants: red tide events along the Florida coast (aerosolized brevetoxins), tobacco smoke, indoor pollutants circulating through air conditioning, and workplace exposures
- ACE inhibitor medications: blood pressure medications ending in "-pril" cause a persistent dry cough in roughly 10 percent of users. Stopping the medication resolves it.
- Post-infectious cough: a cough that lingers for weeks (sometimes months) after a respiratory infection has otherwise cleared
- Smoking or vaping: ongoing airway irritation and inflammation from tobacco or nicotine vapor
When Should You See a Chronic Cough Specialist?
Your cough has lasted 8 weeks or longer, or a child's cough has lasted more than 4 weeks
The cough disrupts your sleep, exercise, work, or social life
You have allergies, asthma, or chronic sinusitis alongside the cough, and current treatments are not working
🚨 RED FLAG: Coughing up blood, unexplained weight loss, fevers, night sweats, worsening shortness of breath, or a changing voice. These urgent signals need evaluation right away and often warrant emergency or urgent care rather than a routine allergist appointment.
How We Treat Chronic Cough
Comprehensive Evaluation (Triple Threat Approach)
Your first visit includes a detailed history of your cough pattern, in-office pulmonary function testing to check for cough-variant asthma, allergy testing to identify UACS drivers, and a targeted assessment for reflux contribution. When more than one cause is at work, we identify each and sequence treatment.
Personalized Treatment Plans
Two patients with chronic cough often have completely different causes, so treatment is never a template. Your plan is built around the specific driver (or combination of drivers) we identify, sequenced so we can see clearly what is working and what needs adjusting.
Long-Term Care & Prevention
Chronic cough can return if the underlying cause is not fully controlled. Our team provides follow-up at our Atlantis, FL and Boynton Beach, FL offices to monitor your response, adjust the plan as needed, and keep the cough from becoming a recurring cycle.
All Ages Welcome
Chronic cough affects children and adults differently, and definitions and workup differ by age. Our experienced team evaluates pediatric chronic cough alongside adult cases, with plans adapted appropriately.
Chronic Cough Testing & Diagnosis
Chronic cough diagnosis is a process of ruling causes in and out systematically. Our specialists use primary in-office diagnostic tools and coordinate imaging when needed.
Pulmonary Function Testing (Spirometry)
In-office spirometry measures how well air moves in and out of your lungs. It is the single most useful test for identifying cough-variant asthma, which often produces normal-sounding breathing but abnormal lung function. It also helps rule out other airway conditions.
Skin Prick Testing
For patients whose cough is driven by allergic rhinitis and post-nasal drip (UACS), skin prick testing pinpoints which pollens, molds, dust mites, or other allergens are keeping the upper airway inflamed.
Specialized Blood Panels
Specialized blood panels provide another way to identify allergen triggers when appropriate, helping treatment target the cause of upper-airway inflammation.
Coordinated Chest Imaging
Chest imaging (X-ray or CT) is coordinated when red flags or persistent unexplained cough warrant it, typically through your primary care physician or a pulmonologist we work with.
Chronic Cough Treatment Options
Chronic cough treatment depends entirely on the cause. Below are the four most common paths patients take with our team.
Treating Upper Airway Cough Syndrome (UACS)
When post-nasal drip from allergic rhinitis is the driver, treatment includes prescription nasal corticosteroids, targeted antihistamines, saline nasal irrigation, and management of the underlying allergies. This is the most common chronic cough path and often the most rewarding, since resolution can be dramatic once the right regimen is in place.
Cough-variant asthma responds to the same treatments as classical asthma: daily inhaled corticosteroids to reduce airway inflammation, short-acting bronchodilators for flares, and biologic therapy for severe or refractory cases. A structured trial of asthma therapy is often the diagnostic confirmation itself.
Identifying GERD-Related Cough and Coordinating Care
When reflux is contributing to your cough, we help identify the pattern (nocturnal cough, worsening after meals, sour taste), often begin an empiric trial of acid-suppression therapy, and coordinate ongoing GERD management with your primary care physician or gastroenterologist. Long-term reflux care is best owned by the specialist responsible for that condition.
Allergy Immunotherapy for Long-Term Trigger Control
For patients whose chronic cough traces back to persistent allergic rhinitis, allergy shots (immunotherapy) can retrain your immune response over time. Especially valuable when medications keep the cough controlled but never fully resolve it, immunotherapy offers a path to lasting change rather than ongoing medication dependence.

Frequently Asked Questions About Chronic Cough
Answers from Florida Allergy & Asthma Associates' experienced specialists
When is a cough considered chronic?
In adults, a cough is considered chronic when it lasts 8 weeks or longer. In children, the threshold is 4 weeks. Anything shorter is classified as acute or subacute cough. If you have crossed the 8-week mark and over-the-counter treatments have not resolved it, a specialist evaluation is worth scheduling.
What are the most common causes of chronic cough?
Three conditions account for most chronic cough in adults: upper airway cough syndrome (post-nasal drip from allergies or sinusitis), cough-variant asthma, and gastroesophageal reflux disease (GERD). Often called the Triple Threat, more than one can be at work at the same time, which is why chronic cough is frequently misdiagnosed and mistreated.
Why is my cough worse at night?
Nighttime cough is a classic sign of either post-nasal drip or asthma. When you lie down, gravity pulls mucus down the throat rather than draining forward, triggering coughing. Asthma airways also naturally narrow overnight due to hormonal cycles and cooler air, which is why asthma symptoms often flare between midnight and dawn.
When should I worry about a chronic cough?
Seek prompt evaluation if you are coughing up blood, losing weight without trying, running unexplained fevers, sweating heavily at night, becoming more short of breath, or noticing voice changes. These red-flag symptoms may signal something more serious than routine chronic cough and typically warrant urgent care or emergency evaluation rather than a routine appointment.
Can allergies really cause a chronic cough?
Yes. Allergies are one of the most common causes, especially in South Florida where allergen exposure is year-round. Allergic post-nasal drip irritates the throat and triggers a reflex cough that can persist for weeks or months. Allergy testing identifies the specific triggers, and treating the underlying rhinitis often resolves the cough completely.
How is chronic cough diagnosed?
Diagnosis is a step-by-step process of identifying and testing likely causes. Your specialist reviews your cough pattern, medications, and history, then performs in-office pulmonary function testing to check for cough-variant asthma and allergy testing to identify potential post-nasal drip triggers. Chest imaging or referral to GI, ENT, or pulmonology is coordinated when needed.
