What information should I give a patient with chronic cough who needs a pulmonology follow‑up, including signs that require emergency department evaluation?

Patient Information for Chronic Cough Follow-Up and Emergency Warning Signs

You should keep your pulmonology appointment and go to the emergency department immediately if you develop any red flag symptoms including difficulty breathing at rest, coughing up blood, high fever, chest pain, or sudden worsening of your cough.

When to Go to the Emergency Department

Go to the ER immediately if you experience any of these warning signs 1, 2:

• Coughing up blood (hemoptysis) - any amount
• Severe shortness of breath, especially at rest or at night
• High fever (temperature ≥38°C/100.4°F) with sweating, chills, or shaking
• Chest pain, particularly sharp pain with breathing (pleural pain)
• Rapid breathing (tachypnea) or feeling like you can't catch your breath
• Swelling in your legs with sudden weight gain (may indicate heart failure)
• Trouble swallowing when eating or drinking
• Persistent vomiting
• Confusion or altered mental status

Additional Urgent Warning Signs (See Doctor Within 24-48 Hours)

Contact your doctor urgently if you have 3, 1, 2:

• New hoarseness lasting more than 2 weeks
• Unintentional weight loss
• Recurrent pneumonia
• If you're a smoker over age 45 with a new cough or change in your usual cough pattern
• If you're age 55-80 with a 30 pack-year smoking history (currently smoking or quit within 15 years)

Before Your Pulmonology Appointment

Track your symptoms 1:

• Note when your cough is worst (morning, night, after eating, with exercise)
• Record if you're coughing up mucus and what color it is
• Document what makes it better or worse
• Rate your cough severity on a scale of 0-10 daily

Bring a complete medication list, especially noting:

• Any ACE inhibitor blood pressure medications (names ending in "-pril" like lisinopril) - these commonly cause chronic cough 4, 5
• All over-the-counter medications and supplements
• Any medications you've tried for the cough

Document environmental exposures 1:

• Workplace chemicals, dust, or fumes
• Recent travel history
• Smoking history (yours and household members)
• Pets or allergen exposures

What to Expect at Pulmonology

The specialist will likely perform 6, 2:

• Spirometry (breathing test) to check for asthma or airway obstruction
• Review of your chest X-ray
• Possibly additional testing based on your symptoms (CT scan, bronchoscopy, or specialized cough testing)

The most common causes of chronic cough are 7, 1:

1. Upper airway problems (postnasal drip, sinus issues)
2. Asthma (including "cough-variant asthma" where cough is the only symptom)
3. Acid reflux (GERD) - even without heartburn
4. Medication side effects

Important Reminders

• If you smoke, stop immediately - smoking cessation resolves cough in most cases within 4 weeks 4
• Don't delay your appointment - chronic cough lasting more than 8 weeks requires specialist evaluation 6, 2
• Keep taking prescribed medications unless specifically told to stop by your doctor
• Avoid irritants like strong perfumes, cleaning chemicals, and secondhand smoke

Special Considerations

If you have fever, night sweats, or have traveled to areas with tuberculosis, mention this immediately as TB must be ruled out even with normal chest X-rays 1.

If your cough started within the past year after beginning a new blood pressure medication, this is likely the cause and should be addressed before extensive testing 4, 5.
