Cough

Home care:

Increasing humidity in the air may help. A vaporizer and a steamy shower are two ways to increase the humidity.

Drink extra fluids to help thin secretions and make them easier to cough up.

Glyceryl guaiacolate (guaifenesin, such as in Robitussin) is available without prescription and may help liquefy the mucus. Drink lots of fluids if taking this medication.

When a cold and a stuffy, runny nose accompany the cough, it is often caused by mucus dripping down the back of the throat. A decongestant that opens the nasal passages will relieve this postnasal drip and is the best treatment for that type of cough. Decongestants such as phenylephrine, pseudoephedrine, phenylpropanolamine, or combinations of all three are available as over-the-counter cold medications. Don't give decongestants to a child under six years of age unless prescribed by the doctor. If hypertensive, consult your doctor before taking decongestants.

Coughs due to chronic postnasal drip are probably caused by either sinus infection or allergy. If allergy is the cause, avoid whatever is causing the allergy and take antihistamines.

Dry, tickling coughs can be relieved by sucking on cough lozenges or hard candy.

Codeine is a very effective cough suppressant but has some negative side effects and requires a prescription. Dextromethorphan (such as in Vick's Formula 44) is an effective cough suppressant that is available without prescription.

Call your health care provider if:

• a violent cough begins suddenly or there is a high-pitched sound (stridor) when inhaling. (The person might have inhaled a small object.)
• there is a cough producing blood in any form. This should be treated as an emergency.
• There is a cough in an infant less than 3 months old.
• There is shortness of breath or difficulty breathing.
• coughing is accompanied by other symptoms such as fever or abdominal swelling.
• a cough is accompanied by unintentional weight loss.
• the cough is producing thick, foul-smelling, rusty, or greenish mucus.
• There is a cough lasting for more than 10 days.

What to expect at your health care provider's office:

In emergency cases, the patient will be treated first to stabilize the condition. After the condition is stable the medical history will be obtained and a respiratory assessment performed.

Medical history questions documenting your cough in detail may include:

• type
  • Are you coughing up blood (hemoptysis)?
    • Is visible blood coughed up (gross hemoptysis)?
    • Is there blood streaked sputum (phlegm)?
    • Are you coughing up large amounts of blood (massive hemoptysis)?
    • Are there repeated episodes of coughing up blood (hemoptysis)?

  • Do you bring up any mucus when you cough (sputum, phlegm)?
    • Does the sputum contain pus (purulent sputum)?
    • Does the sputum contain pus and have a foul odor?
    • Does the sputum look like clear, sticky mucus (mucoid sputum)?
    • Is the sputum white and frothy?
    • Is pink, frothy material coughed up?
    • Is the sputum adhesive, thick, hard to cough up (tenacious)?
    • Are you coughing up brownish plugs?
    • How much sputum is produced (about how many cups per day)?

• quality
  • Is the cough severe?
  • Is the cough dry?
  • Does the cough sound like a seal barking?

• time pattern
  • Is the cough worse at night?
  • Did it begin suddenly?
  • Has it been increasing recently?
  • How long has the cough lasted (for how many weeks?)
  • Has the cough been chronic and has it changed pattern recently?
  • Do spells of coughing occur repeatedly (recurrent)?
  • Are coughing spells composed of a sequence of separate episodes?
  • Does the cough change?
    • Is it variable over hours?

• aggravating factors
  • Is the cough worse when you are lying on one side?
  • Is it worse when first arising from sleep?

• associated complaints
  • Are there sudden periodic attacks of coughing with gagging and vomiting?

• other
  • What other symptoms are also present?

The physical examination will include emphasis on the ears, nose, throat, and chest. Do not expect antibiotics to be prescribed for a routine viral or allergic cough because they will not help.

Diagnostic tests that may be performed include:

• bronchoscopy
• lung scan
• pulmonary function tests
• sputum analysis (if the cough produces sputum)
• X-ray of the chest
