Treatment of Severe Cough with Phlegm

Have you ever woken up in the middle of the night because of a severe cough, feeling suffocated and unable to breathe easily? A severe cough with phlegm is not just an annoying symptom; it can be a warning sign that your respiratory system is facing a challenge that requires attention. While many people ignore it or try to control it in random ways, understanding its causes and choosing the right treatment is the first step toward relief and regaining comfort. Keep reading this article to learn more about what a cough is, its causes, when it becomes a medical concern, and the best ways to treat a severe cough with phlegm.

What is a cough?

Coughing is a natural reflex that the body uses to clear irritants from the airways, whether in the throat or lungs. It acts as a defense mechanism that helps protect the respiratory system and speed up recovery.

Types of cough

Cough can be categorized in several ways depending on different factors:

1. Based on duration

• Acute cough: Starts suddenly and lasts for 2–3 weeks.

• Subacute cough: Persists after an infection for 3–8 weeks.

• Chronic cough: Lasts for more than 8 weeks and is sometimes called persistent cough.

• Refractory cough: A chronic cough that does not respond to treatment.

2. Based on phlegm

• Productive (wet) cough: Produces mucus or phlegm.

• Non-productive (dry) cough: Does not produce mucus.

3. Based on sound or distinctive feature

• Whooping cough: Produces a high-pitched “whoop” sound, usually caused by pertussis infection.

• Barking cough: Sounds like barking and is often linked to croup.

• Wheezing cough: Occurs when airways are obstructed, associated with colds or chronic conditions such as asthma.

4. Based on timing

• Daytime cough.

• Nighttime cough.

• Cough accompanied by vomiting (common in children due to intense coughing).

Causes of Severe Cough with Phlegm

A cough with phlegm (wet cough) may be a symptom of several diseases or health conditions affecting the lungs or even the heart. The most common causes include:

1. Colds and Influenza

• Caused by viral infections. The body tries to expel mucus loaded with viruses and germs.

• Usually accompanied by runny nose, sore throat, sneezing, fever, chills, and body aches.

• Colds typically improve within 7–10 days, while influenza can be more serious, especially with fever and severe fatigue.

2. Acute Bronchitis

• Often called a chest cold, usually lasts about 3 weeks.

• Triggered by viral or bacterial infections, causing swelling of the airways and excess mucus production.

• Symptoms include chest pain, persistent cough, fever, wheezing, and fatigue.

3. Pneumonia

• An infection that fills the alveoli with fluid or pus.

• Patients may produce yellow, green, or sometimes bloody phlegm. Severity ranges from mild to life-threatening.

• Accompanied by fever and breathing difficulties.

4. Postnasal Drip

• Occurs when mucus drips from the nose into the back of the throat, triggering frequent coughing, especially at night.

• Can result from allergies, colds, infections, pregnancy, or certain medications.

5. Chronic Obstructive Pulmonary Disease (COPD)

• Includes chronic bronchitis and emphysema.

• Smoking cigarettes is the most common cause, but it also can occur as a result of air pollution, asthma, or others.

• Leads to excess mucus and chronic coughing.

• Other symptoms include shortness of breath and wheezing, worsening over time.

6. Bronchiectasis

• A chronic condition where airways become scarred and widened, leading to mucus buildup and difficulty clearing it.

• Can develop after cystic fibrosis, pneumonia, tuberculosis, or airway obstruction.

• Causes frequent coughing with phlegm, along with shortness of breath and fatigue.

7. Cystic Fibrosis

• A genetic disease that hinders mucus clearance in the lungs, promoting bacterial growth and recurrent infections.

• Symptoms include chest wheezing, clubbing of fingers, and digestive issues.

8. Congestive Heart Failure

• When the heart cannot pump blood effectively, fluid builds up in the lungs, causing a wet cough and wheezing.

• Phlegm may appear pink in color, with additional symptoms such as shortness of breath, fatigue, and leg swelling.

Dry Cough vs. Productive (Wet) Cough

Dry cough and productive cough differ in their nature and underlying causes as follows:

Dry Cough

• A dry cough is an intermittent cough that does not produce mucus or phlegm. It is often irritating, painful, and difficult to control.

• It usually develops due to irritation or inflammation of the airways without excessive mucus production.

• It may persist for weeks or even months after a respiratory infection has resolved.

Common causes of dry cough include:

• Asthma.

• Laryngitis.

• Tonsillitis. 

• Croup.

• Pulmonary fibrosis.

• Gastroesophageal reflux disease (GERD).

• Allergies or exposure to irritants such as smoke, dust, and pollution.

• Certain medications, especially ACE inhibitors.

• Respiratory infections such as COVID-19.

Productive (Wet) Cough

• This type of cough produces mucus or phlegm as a result of respiratory infections or inflammation.

• The presence of phlegm helps the body expel irritants or infections. It is a common symptom of colds, bronchitis, or pneumonia.

Severe Cough at Night

Nighttime cough can feel worse than daytime cough due to several factors:

• Respiratory infections, allergies, or asthma: Lying down can cause mucus buildup, irritating the throat.

• Postnasal drip: Nasal secretions collect at the back of the throat when lying down, triggering cough.

• Gastroesophageal reflux (GERD): Stomach acid refluxes into the esophagus and throat, causing irritation.

• Certain health conditions: Such as heart failure or sleep apnea.

• Medications: ACE inhibitors (for high blood pressure) may cause a dry cough as a side effect.

• The body’s circadian rhythm: Some immune functions become more active at night, worsening symptoms like congestion and cough.

Severe cough treatment in Adults

Cough treatment depends on its underlying cause. In most cases, it can be relieved with simple home measures, such as:

• Drinking plenty of fluids to soothe throat irritation and loosen mucus.

• Using humidifiers or inhaling steam to relieve congestion.

• Drinking warm beverages with honey or lemon to calm the cough.

• Getting enough rest and avoiding smoking and irritants such as perfumes and smoke.

• Taking pain relievers such as paracetamol or ibuprofen to reduce associated pain.

• Using throat lozenges or cough drops containing menthol or eucalyptus to ease throat discomfort.

Pharmacy Medications for Severe Cough

For the treatment of severe cough with phlegm, pharmacies offer a wide range of medications suitable for different conditions. Some of these are available over the counter, while others require a prescription and should be used under medical supervision.

Severe cough treatment in Children and Infants

Severe cough in children is most often caused by a viral infection, which may gradually resolve on its own. However, if the child is younger than two months and develops a cough, it is important to see a doctor immediately.

In mild cases, some natural home remedies may help relieve symptoms in infants and young children, after consulting a pediatrician, such as:

• Steam bath: Let hot water run for a few minutes, then have your child inhale the steam for 5–10 minutes to help loosen mucus and soothe the airways.

• Honey: Suitable for children over 1 year old; it helps soothe the throat and has antimicrobial properties (not recommended for infants under 12 months).

• Saline nasal rinse: Helps clear nasal passages and relieve congestion. A saline spray with a nasal aspirator can be used, but only with filtered water.

• Humidifier: A cool-mist humidifier keeps the room moist and eases nasal and chest congestion.

• Hydration: Ensure your child gets enough fluids. For infants, increase feeding frequency; for older children, encourage water or electrolyte-rich drinks.

Best Natural Remedies for Severe Cough

A wet (productive) cough often results from respiratory infections such as colds or bronchitis. While medications may not be effective against viral infections, some natural remedies can help ease symptoms, including:

• Honey: Effective in soothing cough and sore throat (for children over 12 months).

• Humidifier: Prevents throat dryness and helps loosen mucus.

• Steam inhalation or warm shower: Moisturizes the airways and breaks down mucus.

• Herbal teas: Such as ginger (anti-inflammatory), thyme, or clove to support immunity and fight infections.

• Herbal cough drops: Made from honey or herbs like lemon, sage, and mint.

• Vitamin C: Boosts immunity and may shorten the duration of cold symptoms.

• Pelargonium extract: May improve cough and bronchitis symptoms.

• Nasal irrigation: Using saline solution with filtered water helps relieve congestion and cough.

• Adequate hydration: Drinking enough water or warm fluids soothes throat irritation and prevents dryness.

When Does Severe Cough Become Serious?

In most cases, cough resolves gradually without special treatment. However, there are situations that require medical evaluation or urgent care.

See a doctor if:

• The cough lasts more than 2 weeks or does not improve after 3 weeks.

• The cough worsens instead of improving.

• It is accompanied by yellow, green, bloody, or foul-smelling phlegm.

• Fever above 38°C appears, especially if it lasts more than 2 days in adults or young children.

• Cough is associated with chest wheezing, chills, or chest pain.

Seek urgent medical care if:

• Severe shortness of breath or difficulty breathing occurs.

• Choking or inability to eat and drink.

• Cough produces a large amount of blood.

• Severe chest pain develops.

• Lips, skin, or nails turn bluish.

• Intense coughing fits occur, sometimes followed by a “whooping” sound.

For children and infants:

• If under 3 months old with a temperature of 38°C or higher.

• If under 2 years old and fever lasts more than 1 day.

• If over 2 years old and fever lasts more than 3 days, or reaches 40°C or higher.

• If wheezing occurs without a prior history of asthma.

• If the cough is accompanied by difficulty waking, seizures, rash with fever, or inconsolable crying.

If the cough is severe or accompanied by alarming symptoms—especially in children and infants—do not delay seeking medical advice or visiting the emergency room.

Does pregnancy cause cough?

Pregnancy itself usually does not directly cause cough, but changes in the immune system can make pregnant women more prone to colds or cough, and symptoms may last longer than usual. It is advisable to consult a doctor if the cough persists longer than expected, or if it interferes with eating, sleeping, or breathing.
