What kind of doctor treats Chronic Cough?
A primary care doctor or a pulmonologist, a doctor who treats lung diseases, often evaluates a chronic cough. Depending on the cause, an allergist (a doctor who treats allergies) or an ear, nose, and throat doctor may also help. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What is a chronic cough?
Coughing is an important way to keep your throat and airways clear. Too much coughing may mean you have a disease or disorder. Some coughs are dry. Others are productive, which means they bring up mucus.
Acute coughs are often due to a cold, flu, or sinus infection, and they usually go away after 3 weeks. Subacute coughs last 3 to 8 weeks. Chronic coughs last longer than 8 weeks.
Symptoms
The main symptom is a cough that lasts longer than 8 weeks. Some people have cough spasms, sometimes called spells, fits, or bouts. These are sudden, often intense coughing episodes that may last several minutes. They may cause chest pain, vomiting, trouble breathing, or bladder leakage.
A chronic cough may also cause vomiting, muscle pain, rib fractures, urinary incontinence (bladder leakage), tiredness, or fainting.
Causes and who gets it
Common causes of a chronic cough include:
- Allergies that involve the nose or sinuses
- Asthma and COPD (emphysema or chronic bronchitis)
- Sinus problems with postnasal drip
- Gastroesophageal reflux disease (GERD)
- Smoking or being around secondhand smoke
Other causes include some medicines, lung cancer, and lung diseases such as bronchiectasis, cystic fibrosis, or interstitial lung disease. The medicines include ACE inhibitors, or less often ARBs, which treat high blood pressure, heart failure, or kidney diseases. Sometimes no specific cause is found.
How doctors diagnose it
Your provider will do a physical exam and ask about your cough. Questions may cover when it began, what it sounds like, whether there is a pattern, what makes it better or worse, and whether you have other symptoms such as a fever.
Tests may include a chest x-ray or CT scan, lung function tests, and blood tests. Other tests may check the heart, such as an echocardiogram, or check for reflux.
Your provider may send you to a specialist, such as an allergist, an ear, nose, and throat specialist, a heart doctor, or an esophagus and stomach specialist.
Treatment
Treatment depends on the cause of the cough. If asthma, COPD, or GERD is causing the cough, specific treatments from your provider may help. They may help get rid of the cough or at least make it more manageable.
The American Lung Association says no medicine is approved by the FDA in the United States to treat chronic cough. Some people have a chronic cough that has no clear cause or does not respond to treatment. Certain neurological medicines may help reduce the cough reflex for them. These are used off-label, which means the FDA has not approved them for this use. Your provider will work with you to find the right dose and watch for side effects. Your provider may also suggest a speech-language pathologist, who can teach behavioral cough suppression therapy.
Lifestyle changes are not a cure, but they may help you manage your cough. You can try these steps:
- Avoid things that trigger your cough, such as dust.
- Avoid tobacco smoke, which is a lung irritant and can worsen your cough.
- Drink lots of fluids to help thin mucus.
- Soothe your throat with hard candy, cough drops, or honey. Do not give honey to infants under one year old.
- A cool-mist humidifier may help. Clean its water basin often to prevent mold.
When to see a doctor
Call 911 or go to the emergency room if you have shortness of breath or trouble breathing, if you faint, or hives or a swollen face or throat with trouble swallowing. Also call 911 or go to the emergency room if you are coughing up blood. See your health care provider for a thorough exam if a cough goes on for longer than 8 weeks.
Talk to your provider or get urgent medical care if your cough comes with fever, drenching night sweats, unexplained weight loss, wheezing, hoarseness, or trouble swallowing. Contact a provider right away if an infant younger than 3 months old has a cough.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance, while a concierge doctor usually charges more and often works alongside insurance. Either type of doctor can do a physical exam, ask about your cough, and arrange first tests such as a chest x-ray. If needed, they can send you to a specialist, such as an allergist or an ear, nose, and throat specialist.

It depends on the cause. If a condition such as asthma, COPD, or GERD is causing the cough, treating it may help get rid of the cough or at least make it more manageable.
Can medicine cause a chronic cough?
Yes, some medicines can cause a cough. Examples are ACE inhibitors, or less often ARBs, which treat high blood pressure, heart failure, or kidney diseases. Your provider can help treat the underlying cause.
