Asthma in Children
Treatment Overview
Although your child's asthma cannot be cured, you can manage the symptoms with medications, especially inhaled corticosteroids and beta2-agonists. You and your child will usually work with your health professional to develop a management plan consisting of a daily treatment plan and an asthma action plan. These plans help you and your child meet treatment goals:
- Increase lung function by treating the underlying inflammation
in the lungs.
- Decrease the severity, frequency, and duration of asthma attacks by avoiding triggers.
- Treat acute attacks as they occur.
- Use quick-relief medicine less (ideally not more than 2 times per week).
- Have a full quality of life—the ability to participate in all daily activities, including school, exercise, and recreation—by preventing and managing symptoms.
- Sleep through the night undisturbed by asthma symptoms.

Asthma education programs provided by certified asthma educators (CAEs) are available in most areas. Ask your doctor or contact the Asthma Society of Canada, the Canadian Lung Association, or the Canadian Network for Asthma Care to learn about asthma education programs.

Babies and small children need early treatment for asthma symptoms to prevent severe breathing problems. They may have more serious problems than adults because their bronchial tubes are smaller. Although it may appear that occasional treatment with medications for children with mild asthma is enough, one review has noted that one-third of fatal asthma attacks occurred in children with mild asthma.19 Even if your child's asthma does not appear severe, work with your health professional to develop the right plan for your child.
Some experts suggest using the "rule of two" in treating young children. This states that young children should be treated with long-term medications for persistent asthma if they:19
- Have symptoms more than 2 times a week.
- Awaken at night because of asthma more that 2 times a month.
- Use more than 2 canisters of a quick-relief medication per year.
The U.S. National Asthma Education and Prevention Program (NAEPP) recommends treatment with long-term medications for infants and young children who:20
- Consistently need treatment for symptoms more than 2 times per week.
- Have severe attacks more than once every 6 weeks.
- Have wheezing more than 3 times per year lasting longer than 1 day and affecting sleep and who have parents with a history of asthma or atopic dermatitis.
- Have wheezing more than 3 times a year lasting longer than 1 day and affecting sleep and two of the following three symptoms:
- Wheezing not associated with colds
- Allergic rhinitis
- A high eosinophil count. Eosinophils are a type of white blood cell often present in allergic reactions.
Emergency treatment
If your child has a severe asthma attack (the red zone of the asthma action plan), give him or her medication based on the action plan and talk with a health professional immediately about what to do next. This is especially important if your child's peak expiratory flow (PEF) does not return to the green zone or stays within the yellow zone after he or she takes medication. You and your child may have to go to the hospital or an emergency room for treatment.
At the hospital, your child will probably receive inhaled beta2-agonists and corticosteroids. He or she may be given oxygen therapy. Doctors will assess your child's lung function and condition. Depending on the response, further treatment in the emergency room or a stay in the hospital may be necessary.
Medical checkups
Your child needs to monitor his or her asthma and have regular checkups to keep asthma under control and to ensure correct treatment. The frequency of checkups depends on how your child's asthma is classified. Checkups are recommended:
- About every 6 to 12 months for children with mild intermittent or mild persistent asthma that has been under control for at least 3 months.
- Every 3 to 4 months for children with moderate persistent asthma.
- Every 1 to 2 months for children with uncontrolled or severe persistent asthma.
During checkups, your health professional will check to see that all your goals are being met. He or she will ask you and your child whether symptoms and peak expiratory flow have held steady, improved, or become worse, and about asthma attacks during exercise, at night, or after laughing or crying hard. You track this information in an asthma diary. Your child may be asked to bring the peak expiratory flow meter to an appointment so your health professional can see how he or she uses it.
Initial treatment
There are many components to managing asthma. Because asthma develops from a complex interaction of genetics, environmental factors, and the reaction of the immune system, no one plan will be effective for all children. After your child's diagnosis, your health professional may only discuss the components you need to know immediately. These include:
- Oral or injected corticosteroids (systemic corticosteroids). These medications may be used to get your child's asthma under control before he or she starts taking daily medication. In the future, your child also may take oral or injected corticosteroids to treat any sudden and severe symptoms, such as shortness of breath (asthma attacks). Oral corticosteroids are used more than injected corticosteroids. Systemic corticosteroids include prednisone and dexamethasone.
- Inhaled corticosteroids. These are the preferred medications for long-term treatment of asthma. They reduce the inflammation
- Short-acting beta2-agonists. These medications are used for asthma attacks. They relax the airways, allowing your child to breathe easier. Short-acting beta2-agonists include salbutamol and terbutaline.
- Basic education about asthma. The more you and your child know about asthma, the more likely it is you will control symptoms and reduce the risk of asthma attack. Keep in mind that even severe asthma can be controlled, and cases where the condition cannot be controlled are unusual.
- Instruction on how to use a metered-dose inhaler (MDI) or dry powder inhaler (DPI). An MDI delivers inhaled medications directly to the lungs. If your child uses the inhaler correctly, he or she can control the symptoms and avoid asthma attacks that can result in emergency care. Most health professionals recommend using a spacer
The short-term goal is to control your child's current symptoms. Long-term, your goal is to prevent your child's symptoms so that asthma does not impact your child's daily activities.
Special considerations in treating asthma include:
- Managing exercise-induced asthma. Exercise often causes asthma symptoms. Steps you and your child can take to reduce the risk of this include using medication immediately before exercising.
- Managing asthma before surgery. Children with moderate to severe asthma are at higher risk of developing problems during and after surgery than children who do not have asthma.
Ongoing treatment
After your child's initial treatment for asthma, it is important for you and your child to learn more about the condition and develop an overall plan to manage the disease. You, your child, and your health professional will work together to do this. Because asthma develops from a complex interaction of genetics, environmental factors, and the reaction of the immune system, no one management plan is effective for everyone.
Asthma management consists of:
- A daily asthma treatment plan. A daily asthma treatment plan outlines in writing how to treat inflammation in your child's lungs. The plan helps prevent or slow the development of the long-term effects of asthma and tells you which medications to take every day. A daily treatment plan may include an asthma diary where your child records peak expiratory flow (PEF), symptoms, triggers, and quick-relief medication used for asthma symptoms. This valuable tool helps you and your child and your health professional manage your child's asthma. A daily asthma treatment plan is often combined with an asthma action plan.
- An asthma action plan. An asthma action plan contains directions to help you and your child better control asthma attacks at home. It helps you identify triggers that can be changed or avoided, be aware of your child's symptoms, and know how to make quick decisions about medication and treatment. For more information, see:
Using an asthma action plan.

(What is a PDF document?).
- Monitoring peak expiratory flow. It is easy to underestimate the severity of your child's symptoms. You may not notice them until his or her lungs are functioning at 50% of the personal best peak expiratory flow (PEF). Measuring PEF is a way to keep track of asthma at home; it can help you and your child know when lung function is becoming worse before it drops to a dangerously low level. This is done with a peak flow meter. For more information, see:
- A plan to deal with factors that can make asthma worse (triggers). Being around triggers increases symptoms. Try to avoid situations that expose your child to irritants (such as smoke or air pollution) or substances (such as animal dander) to which he or she may be allergic. See information on:
- A plan to treat other health problems. If your child also has other health problems, such as inflammation and infection of the sinuses (sinusitis) or gastroesophageal reflux disease (GERD), he or she will need treatment for those conditions.
- Using the prescribed medications correctly. Your health professional may adjust your child's medications depending on how well your child's asthma is controlled. Medications include:
- Inhaled corticosteroids. These are the preferred medications for long-term treatment of asthma. Inhaled corticosteroids include beclomethasone dipropionate, fluticasone propionate, and budesonide.
- Long-acting beta2-agonists (such as salmeterol and formoterol), which are generally used along with inhaled corticosteroids.
- Oral or injected corticosteroids (systemic corticosteroids) to treat any sudden and severe symptoms, such as shortness of breath (asthma attacks). Oral corticosteroids are used more than injected corticosteroids. Oral corticosteroids include prednisone and dexamethasone.
- Quick-relief medication, such as short-acting beta2-agonists and anticholinergics (ipratropium ) for asthma attacks. If your child is using quick-relief medication more than 2 times a week (other than once a day to prevent exercise-induced asthma) or more than 1 canister in 3 months, he or she probably needs more long-term treatment. Overuse of quick-relief medication can be harmful.
- Education. Continue to learn about asthma. This questionnaire can help you and your child determine what you already know about asthma and what you may need to discuss with your health professional.
If your child has persistent asthma and reacts to allergens, he or she may need to have skin testing for allergies. Allergy shots (immunotherapy) may be helpful. For more information, see:
Your child can expect to live a normal life if he or she controls symptoms by following the daily treatment and action plans. If asthma symptoms are not controlled, the disease may progress, permanently damaging the bronchial tubes that carry air to the lungs.
Special considerations in treating asthma include:
- Managing exercise-induced asthma. Exercise often causes asthma symptoms. Steps you can take to reduce the risk of this include using medication immediately before exercising.
- Managing asthma before surgery. People with moderate to severe asthma are at higher risk than people who do not have asthma of developing problems during and after surgery.
Treatment if the condition gets worse
If your child's asthma is not improving, talk with your doctor and:
- Review your child's asthma diary to see if he or she has a new or previously unidentified trigger, such as animal dander. Talk to your health professional about how best to avoid triggers.
- Review your child's medications, to be sure he or she is using the right ones and using them correctly.
- Review your child's asthma plans, to be sure they are suitable for his or her condition.
- Determine whether your child has a condition with symptoms similar to asthma, such as sinusitis.
If your child's medication is not working to control airway inflammation, your health professional will first check to see whether your child is using the inhaler correctly. If your child is using it correctly, your health professional may increase the dosage, switch to another medication, or add a medication to the existing treatment. You can work with your health professional or asthma educator to educate your child about the importance of taking medications correctly and to encourage your child's teachers, babysitters, and other adults to help your child follow his or her plan.
Your doctor may suggest other medications, such as leukotriene pathway modifiers (zafirlukast or montelukast sodium). Less commonly, your doctor may recommend mast cell stabilizers (cromolyn sodium or nedocromil) or theophylline (Uniphyl).
If your child's asthma does not improve with treatment, he or she may require more intensive treatment, including larger doses of corticosteroids or other medications. An asthma specialist generally prescribes these medications.
If your child has persistent asthma and reacts to allergens, he or she may need to have skin testing for allergies. Allergy shots (immunotherapy) may be helpful.
What to think about
If your child has been diagnosed with asthma, it is important that you treat it. He or she may feel good most of the time—so much so that it may be hard to believe your child has a long-lasting condition. But all asthma—even mild asthma—may result in changes to the airways that speed up and worsen the natural decrease in lung function that occurs as we age.3
