What is asthma?
Asthma causes the airways to become narrow, which makes it hard for your child to breathe. Asthma often starts in childhood, especially before age 5.
Many common things can trigger asthma attacks, such as a cold, allergies, or breathing dust
During an asthma attack, your child may wheeze, cough, or feel short of breath
Doctors prescribe medicines for your child to take during an asthma attack, and sometimes medicines to help prevent attacks
Some children stop having asthma by the time they become adults
With an asthma attack, 2 things happen:
The muscles around the airways tighten up
The airways swell and fill with thick fluid (mucus)
Because of these things, your child's airways become narrow, making it hard to breathe.

How do doctors treat asthma in children?
To treat mild asthma attacks, doctors will have your child:
Use an inhaler to take a fast-acting (rescue) medicine to open the airways
The rescue medicine is a called a bronchodilator. Your child can use a bronchodilator inhaler 1 to 3 times, 20 minutes apart if needed.
To treat severe asthma attacks, go to a hospital emergency department right away or call for emergency medical help (911 in the United States). Doctors will:
Give a rescue medicine by inhaler or sometimes in a shot
Often give a corticosteroid drug to reduce swelling in your child’s airway
Give your child extra oxygen if needed
Sometimes, start an IV to give medicine in your child's veins
Sometimes, admit your child to the hospital
Rarely, put a breathing tube in your child's windpipe
How can I help my child prevent asthma attacks?
Check your child’s airflow with a peak flow meter. A peak flow meter is a handheld device that measures how fast your child can blow air out. It'll help you know when your child needs medicine.
Some children need to take long-lasting (maintenance) medicines every day. There are many different maintenance medicines. Some are inhalers and some are pills. Your child may need more than one kind of medicine.
Help your child avoid things that trigger asthma attacks:
Keep cigarette smoke, strong smells, and fumes out of your house
Help your child avoid cold air
If needed, have your child use an inhaler before exercising
Have your child use a pillow made of man-made materials and a mattress cover to protect against dust mites
Wash sheets and blankets in hot water
Keep your house clean to avoid dust mites and cockroaches
Use a dehumidifier to dry out the air in any damp places like a basement
How does a child take asthma medicine?
Overusing asthma medicines is dangerous. Tell the doctor if your child has to use the medicine more often than prescribed.
A lot of asthma medicine is taken using an inhaler or a nebulizer.
Inhalers
Inhalers (also called metered-dose inhalers) are small, hand-held devices. They are the most common way to take asthma medicines. They turn medicine into a fine spray your child can breathe. An inhaler that has a spacer or holding chamber is easier to use.
Nebulizers
Nebulizers are electric or battery-powered machines that turn liquid medicine into a fine spray your child can easily breathe in through a mask. A nebulizer is too big to carry around.
