Asthma is a common condition caused by narrowing of the small air passages (breathing tubes/bronchi) in the lungs. The air passages of children with asthma are particularly sensitive, and various different triggers can cause them to become swollen and inflamed. Swelling and inflammation of the air passages makes it harder for air to get through, and may cause wheezing, coughing or difficulty breathing. In the absence of triggers, many children with asthma have no symptoms at all.

About one in four children will have wheezing sometime during childhood. With the right medicine and treatment, nearly all children with asthma will be able to join in sport and lead active lives.

Signs and symptoms

The most common signs of asthma are:

If your child has wheezing, coughing or problems breathing, it is important to talk to your doctor about whether it might be asthma.



There are many different things that can start or trigger an asthma attack. It is not always possible to know when an attack will occur. Some common trigger factors are:

It can be helpful for parents to know what may trigger asthma in their child, so that triggers can be avoided where possible.

Asthma can be well controlled with the right medicine in nearly all children. The two types of medication used by children are:


Relievers help during an exacerbation. These include:

These are called bronchodilators and are used only in an exacerbation (asthma attack). They relax the narrowing of the breathing tubes making it easier for air to get through.

For acute/sudden attacks, your child will need Ventolin every two to four hours. If your child needs it more often, you should speak with your doctor.

Prednisolone (a type of steroid (liquid or tablet))

Prednisolone helps by making the breathing tubes react more to Ventolin. It also reduces the swelling of the lining of the air passages. Prednisolone is given as a syrup or tablet and will often take about six to eight hours to work. Your child will usually need it for two to four days. You may have read about side effects from prednisolone. These happen when the medicine is given for months at a time. These side effects will not happen when the prednisolone is given for a few days.


Preventers aim to prevent attacks from happening in the first place. Their job is to make the lungs less sensitive, so that when a trigger comes along, the child will get much milder symptoms. These are the most important medications for asthma control and it is vital that they are given regularly, and in the correct manner. They are usually given as inhalers.

Preventative medicines have to be taken every day. Your child will need to see their local doctor regularly if they have preventative medicines. The doctor will make sure the preventative medicines are working and will adjust the dose of medicine to suit your child's needs. Not all children need preventer medicine.

Combination Inhalers – Seretide/Symbicort

When symptoms of asthma are cannot be controlled by regular preventers alone, a group of medicines called combination inhalers may also be used. These inhalers have two components, a preventer and a long acting reliever. Seretide is a combination inhaler containing Flixotide (preventer) and Serevent (long acting reliever). Similarly, Symbicort contains Pulmicort (preventer) and Formoterol (long acting reliever).

Asthma Action Plans

If your child has asthma, ask your doctor to write down an Asthma Action Plan. The plan will tell you how to prevent asthma attacks and how to manage asthma attacks when they happen. The plan should be kept in a place where you can find it easily.
