Cough
Description
A cough is the sound made when the cough reflex suddenly expels air and secretions from the lungs.
A coughing spasm is > 5 minutes of continuous coughing.
Cause
Most are part of a cold, a viral infection of the large airway (viral bronchitis). Other common causes: croup, bronchiolitis, asthma, allergic cough.
Sputum or phlegm:
- Yellow or green phlegm is a normal part of the healing process of viral bronchitis
- This means the lining of the trachea was damaged by the viral infection and is being coughed up as new mucosa replaces it
- Bacteria do not cause bronchitis in healthy children. Antibiotics are not indicated for the yellow or green phlegm seen with colds
- The main treatment of a productive cough is to facilitate it with good fluid intake, a humidifier (if the air is dry) and warm chicken broth or apple juice for coughing spasms (if over age 1).

Home Care (Read "Call Your Doctor…" first):
Cough Medicine for Mild Coughs
After age 1 year, use corn syrup ½ to 1 tsp as needed as a homemade cough medicine. It can thin the secretions and loosen the cough. After age 4, use cough drops.
Cough Suppressant for Severe Coughs
For coughs that interfere with sleep, school or work, use dextromethorphan (DM) which is present in most cough syrups. Do not use under 1 year old.
Coughing Spasms
For coughing spasms, give warm fluids (e.g. apple juice). Expose to warm mist (e.g. foggy bathroom). (Reason: both relax the airway and loosen up the phlegm). (Avoid juice if < 4 months old).
Children > 4 years can suck on hard candy or cough drops. (Reason: to coat the irritated throat). Also, try not to talk or cough at these times.
Vomiting
For vomiting that occurs with hard coughing, reduce the amount given per feeding (e.g. in infants, give 2 oz. less formula). (Reason: cough-induced vomiting is more common with a full stomach).
Humidifier
If the air is dry, use a humidifier. (Reason: dry air makes coughs worse).
Fever Medicine
For fever > 102°F (39°C), give acetaminophen (e.g. Tylenol) or ibuprofen.
Avoid Tobacco Smoke
Active or passive smoking makes coughs much worse.
Contagiousness
Your child can return to day care or school after the fever is gone and your child feels well enough to participate in normal activities. For practical purposes, the spread of coughs and colds cannot be prevented.
Expected Course
Viral bronchitis causes a cough for 2 to 3 weeks. Sometimes the child coughs up lots of phlegm (mucus). The mucus can normally be gray, yellow or green. Antibiotics are not helpful.
Coughing up mucus is very important for protecting the lungs from pneumonia. We want to encourage a productive cough, not turn it off.
Call Your Doctor If:
- Difficulty breathing occurs
- Wheezing occurs
- Cough lasts > 3 weeks
- Your child becomes worse or develops any of the "Call Your Doctor…" symptoms
