Doctors evaluate cough in a lot of ways. You can tell your doctor about how the cough feels and other symptoms that accompany it. You can also mention what you think might have triggered the cough. But, an important first clue for doctors is whether the cough is productive or nonproductive. Read on to learn what makes a cough productive or nonproductive. We will also tackle the unique causes of each type of cough and their treatment.

Productive vs. Nonproductive Cough – Causes & Treatments
A productive cough brings up mucus or other fluids, including blood. Often referred to as a wet cough, a productive cough produces a gurgling sound. Most coughs (like the common cold and flu) will disappear after a few days. However, a productive cough can last more than a few weeks. Symptoms involve fever, greenish-yellow phlegm, and shortness of breath.
Here are some lung conditions that are associated with a productive cough:
- Acute Bronchitis
- Cystic Fibrosis
- Gastroesophageal Reflux Disease (GERD)
- Chronic Obstructive Pulmonary Disease (COPD)
Also known as a dry cough because of the “scratchy” or “tickling” sensation associated with it, nonproductive cough does not bring up any mucus or secretions. Moreover, this cough tends to irritate the throat and other airways.
A dry cough could be indicative of several conditions. While a cold is a common cause of dry cough, this could also be a sign of:
- Swollen Airways (due to Asthma and Bronchitis)
- Other Upper-Respiratory Infections
Common Causes I Explanations & Symptoms
Asthma is a condition in which tightening of the airways is typical. Some asthma symptoms include tightness or chest pain, shortness of breath, stridor, wheezing or coughing attacks, etc.
Although asthma-related coughs can be both productive and nonproductive, most asthmatics have a dry cough. For example, a chronic dry cough is the main symptom of cough variant asthma (CVA).
When mucus accumulates in your sinuses, it tends to drip down to the back of your throat. This fluid movement is called postnasal drip. The nasal membranes produce excessive mucus whenever you have colds or seasonal allergies. Moreover, this type of mucus is watery and runny, easily dripping down your throat, causing a tickling sensation that can trigger a cough.
Other symptoms of postnasal drip include:
- A runny nose
- Difficulty swallowing
- A sensation of a lump in the throat
Gastroesophageal Reflux Disease
Gastroesophageal reflux disease (GERD) is a type of chronic acid reflux. GERD happens when the lining of the esophagus – the passage between mouth and stomach – is irritated by acid backflow from the stomach. The irritation and inflammation can trigger your cough reflex.
Symptoms of GERD include:
- Chronic cough & sore throat
- Chest pain
- Acidic taste in the mouth
When you experience a common cold, symptoms usually last less than a week. But, a cough may linger long after other symptoms have disappeared or improved (up to two months). This residual cough might result from airway irritation or hypersensitivity after a viral illness.
Other Less Common Causes
Environmental pollutants can irritate your airways. These include pollen, smoke, dust, pollution, mold, etc. Even clean air that is too dry or too cold can trigger a dry cough in some people.
ACE inhibitors are prescription drugs that lower your blood pressure. However, one of this drug class’ most common side effects is precisely a dry cough. Around 20 percent of people who take ACE inhibitors experience dry coughing, according to Harvard Health.
Also known as pertussis, whooping cough causes a severe dry cough. The cough is accompanied by a high-pitched “whooping” sound when inhaling. This sign is more common in young or unvaccinated children. However, teens or adults with decreased immunity may also get infected.
Collapsed Lung & Lung Cancer
A collapsed lung (or pneumothorax) is when the lung suddenly deflates. This can happen either independently or as a result of a chest injury. Pneumothorax can lead to shortness of breath and sudden chest pain. Occasionally, persistent dry cough may also point to cancer. Lung cancer-related coughs usually do not disappear. They may also change over time (e.g., become more painful, sound differently).
Heart failure is a condition where the heart muscles lose their ability to pump blood effectively. This condition has several possible symptoms, notably persistent or dry cough.
It All Depends on the Underlying Cause
Treatment of productive and nonproductive cough depends on the underlying cause.
Each condition requires appropriate treatment:
- Antihistamines for seasonal allergies
- Inhaled bronchodilators for asthma
- Antacids and proton-pump inhibitors for GERD
- Antibiotics for infections
- Oxygen therapy or medications (inhaled/oral) for chronic disorders like COPD
For a productive cough caused by a cold, it is easier to expel mucus using an expectorant. Above all, follow your doctor or pharmacist’s advice to find an appropriate and safe over-the-counter (OTC) expectorant.
Definition: Over-the-counter medicine (OTC or nonprescription medicine) are medications you may buy without a prescription. These are safe and effective as long as you follow the label’s indications or your health care professional’s directions.
A nonproductive cough can be challenging to deal with due to the vicious cycle. In other words, an undesirable feedback loop of oversensitive airways, irritation, and more coughing. Here are a few ways you can alleviate the discomfort:
- A hot drink with honey (to soothe irritated throat tissue)
- Taking OTC cough suppressants (to suppress the cough reflex)
- Sucking on throat lozenges (to moisturize and soothe irritated throat tissue)
