Key Takeaways
- Brown mucus (also called brown phlegm) can indicate old blood, environmental pollutants, or airway inflammation.
- Coughing up brown mucus may result from infections, chronic lung conditions, or exposure to irritants like smoke or dust.
- Brown mucus can appear as brown mucus from the nose, brown mucus from the throat, or phlegm with brown flecks.
- Persistent brown phlegm with blood or blood and mucus from the throat warrants medical evaluation.
- Severe symptoms, including thick, rubbery mucus from the throat, may require urgent care at our emergency room in Mueller.
What Does Brown Mucus Mean?
Brown mucus, also called brown phlegm, often signals the presence of old blood, pollutants, or debris in the airways due to irritation or infection. It can appear after coughing up dried blood or inhaling irritants like smoke, and persistent brown mucus may signal chronic respiratory issues. A systematic review on sputum color in COPD found that darker mucus had an 81% sensitivity for bacterial involvement, though color alone isn’t diagnostic.
Brown Mucus Symptoms
- Thick or brown colored mucus.
- Coughing up brown mucus or brown mucus spit.
- Brown mucus and cough or persistent cough with discolored phlegm.
- Phlegm with brown flecks or streaks.
- Blood in mucus from the throat or brown phlegm with blood.
- Chest discomfort or mild shortness of breath.

What Causes Brown Mucus?
Brown mucus often reflects the body’s effort to clear irritants, blood remnants, or infection from the respiratory system. It can appear due to airway inflammation, environmental exposures, or chronic lung conditions. Identifying the cause is essential for proper treatment and preventing complications.
Smoking and Tobacco Exposure
Smoking introduces tar and chemicals into the lungs, which mix with mucus, producing brown phlegm. Chronic exposure damages airway cilia, making mucus thick and difficult to clear. Over time, this can lead to chronic bronchitis or other lung issues. Persistent coughing up brown mucus is common in long-term smokers.
Treatment
- Prescription bronchodilators
- Inhaled corticosteroids
- Nicotine replacement therapy
- Pulmonary rehabilitation
Bacterial or Viral Respiratory Infection
Respiratory infections such as bronchitis or pneumonia can cause inflammation and minor bleeding, producing brown or rusty mucus. Fever, fatigue, and productive cough often accompany these infections. Phlegm may appear brownish yellow or contain brown flecks. Early treatment prevents complications and worsening symptoms.
Treatment
- Antibiotics for bacterial infections
- Antiviral medication when indicated
- Supportive respiratory therapy
Chronic Obstructive Pulmonary Disease (COPD)
COPD causes chronic inflammation of the airways, leading to brown phlegm due to irritation and occasional bleeding. Persistent coughing and shortness of breath are common. Exposure to pollutants or repeated infections can worsen mucus discoloration. Early symptom management reduces further airway damage.
Treatment
- Long-acting bronchodilators
- Inhaled corticosteroids
- Supplemental oxygen for advanced disease
- Pulmonary rehabilitation
Bronchiectasis
Bronchiectasis causes permanent airway widening, resulting in mucus accumulation that is often brown or blood-tinged. Chronic cough and phlegm with brown flecks are common, especially after activity. Early detection and treatment prevent further lung tissue damage.
Treatment
- Chest physiotherapy
- Inhaled antibiotics for chronic infections
- Regular vaccinations
- Mucolytics
Lung Abscess
A lung abscess is a pus-filled cavity in lung tissue, usually from bacterial infection. When it drains into the airways, it produces foul-smelling brown mucus. Symptoms include fever, night sweats, and a persistent cough. Prompt medical care prevents systemic infection and lung damage.
Treatment
- Extended course of antibiotics
- Percutaneous drainage under imaging guidance
- Hospitalization for severe cases
Post-Smoking Cessation Cleanup
After quitting smoking, the lungs expel accumulated tar and debris, resulting in brown phlegm. This is usually temporary but can persist for weeks. Patients may notice brown mucus after coughing or thick, rubbery mucus in the throat. Monitoring ensures safe recovery without complications.
Treatment
- Continued smoking cessation support
- Follow up with the healthcare provider
- Respiratory therapy if mucus clearance is difficult
When Is It an Emergency?
Sometimes, brown mucus signals an urgent medical condition. Seek help if symptoms are sudden, severe, or accompanied by warning signs. A quick evaluation can prevent serious complications, especially with brown phlegm with blood. Early intervention improves outcomes.
Emergency Signs
- Don’t ignore coughing up large amounts of blood in mucus from the throat.
- Don’t delay care for severe shortness of breath.
- Don’t wait if you experience chest pain or pressure.
- Don’t tolerate high fever with discolored phlegm.
- Don’t ignore confusion, dizziness, or fainting.
If these signs appear along with brown mucus after coughing, contact the Austin Emergency Center immediately.
How to Get Rid of Mucus Naturally
Excess mucus can be uncomfortable and interfere with breathing. Supporting your body naturally helps clear brown mucus in the throat, thick, rubbery mucus from the throat, and other phlegm issues. These methods complement medical treatment and promote airway clearance.
- Hydration and Warm Fluids: Staying hydrated thins mucus, making it easier to expel brown phlegm.
- Humidified Air: Moist air reduces airway irritation and helps clear brown mucus from the nose.
- Steam Inhalation: Warm steam softens mucus, promoting clearance of mucus and brown discharge.
- Breathing Exercises: Techniques like controlled coughing and deep breathing mobilize brown phlegm.
- Elevated Sleeping Position: Sleeping upright reduces post-nasal drip and accumulation of brown mucus in the throat.
- Avoiding Irritants: Limiting exposure to smoke, dust, and strong odors minimizes ongoing brown colored mucus formation.
