Cough
What is a cough?
A cough is a common symptom of illness. Although coughs often
sound bad, keep in mind that coughing is a good reflex that clears
out the airways in the lungs and protects your child from getting
pneumonia.
Your child may have a dry and hacking type of cough. Or your child
may have a wet cough and cough up a lot of mucus. When your child
continuously coughs for more than 5 minutes, it is called a
coughing spasm.
What is the cause?
Most coughs are caused by a viral infection. An infection of the
trachea (windpipe) is called tracheitis. An infection of the
bronchi (larger air passages in the lungs) is called bronchitis.
Most children get such a viral infection a couple of times a year
as part of a cold. These infections are usually not serious.
How long will it last?
Usually bronchitis causes a dry tickly cough that lasts 2 to
3 weeks. Sometimes the cough becomes loose (wet) for a few days,
and your child coughs up a lot of phlegm (mucus). This is usually
a sign that the end of the illness is near.
How can I take care of my child?
- Medicines to loosen the cough and thin the secretions
Cough drops: Most coughs in children over age 6 years can be
controlled by sucking on cough drops. The cough drops coat the
irritated throat. If cough drops are not available, you can
use hard candy.
Homemade cough syrup: For children over 1 year old use 1/2 to
1 teaspoon of honey. The honey thins the secretions and
loosens the cough. A recent study showed it was more effective
at reducing coughing than OTC cough syrup containing
dextromethorphan (DM).
Warm liquids for coughing spasms: Warm liquids usually relax
the airway and loosen up the mucus. Start with warm lemonade,
warm apple juice, or warm herbal tea. (Avoid this if your
child is less than 4 months old.) Do not add liquor because
it may aggravate the cough if your child inhales the fumes of
alcohol into his lungs. Also, your child could become
intoxicated from an unintentional overdose.
- Cough-suppressant medicines
Cough medicines are not as helpful as honey. They should not
be given to children under 4 years old because they can cause
serious side effects. In general, you should not give these
medicines to children. Coughing helps protect the lungs by
clearing out germs. If the coughing lasts for more than a
couple of days, check with your child's healthcare provider.
- Humidifiers
Dry air tends to make coughs worse. Dry coughs can be loosened
up by encouraging your child to drink plenty of liquids and by
using a humidifier in your child's bedroom.
- Exercise
Gym and exercise may trigger coughing spasms when children
have bronchitis. If so, they should avoid such physical
activity temporarily.
- Active and passive smoking
Don't let anyone smoke around your child.
- Common mistakes in treating cough
Antihistamines, decongestants, and fever medicines are found
in many cough syrups. There is no proof that these ingredients
will help your child's cough, and the antihistamines may make
your child sleepy. Expectorants are of unproven value but
harmless. Cough and cold medicines should never be given to
children under 4 years of age. Stay with the simple home
remedies mentioned above or talk with your provider.
Milk does not need to be eliminated from the diet. Restricting
it improves the cough only if your child is allergic to milk.
Never stop breast-feeding because of a cough.
When should I call my child's healthcare provider?
Call IMMEDIATELY if:
- Breathing becomes difficult AND is not better after you clear
the nose.
- Breathing becomes fast or labored (when your child is not
coughing).
- Your child starts acting very sick.
Call during office hours if:
- A fever (over 100°F, or 37.8°C) lasts more than 3 days.
- The cough lasts more than 3 weeks.
- You have other concerns or questions.
