Cromolyn

What is cromolyn used for?

Cromolyn is a medicine used to prevent asthma symptoms. It's also called an asthma controller medicine, because by taking it regularly every day, it helps to control your child’s symptoms. Your child will take this medicine every day, even if your child is not having symptoms. It does not provide quick relief of wheezing in acute asthma attacks. For acute asthma attacks, your child will need a different type of medicine called a reliever.

Your child's asthma symptoms are caused by two different problems in the airways.

• One problem is that the muscles in the airways tighten up, which causes the feeling of chest tightness and wheezing.
• The other problem is swelling, irritation and too much mucus in the airways.

Your child's asthma symptoms often start after exposure to a trigger. Asthma triggers can include pollen, animals, mold, colds, exercise, cold air, and air pollutants. It is important for you and your child to know what things trigger your child's asthma. Help your child avoid the things that trigger his asthma. Your child should keep his reliever medicine with him at all times in case he has an asthma attack.

How does it work?

Cromolyn helps to prevent your child’s asthma symptoms by blocking the allergic response to triggers. When your child has exposure to a trigger, it causes swelling and irritation in the airways. By lessening the swelling, your child will have fewer symptoms and be able to breathe better.

Cromolyn is commonly given with a nebulizer. A nebulizer is a machine that your child uses at home. Medicine is mixed with liquid and the machine forms a mist. Your child will breath in the mist to help get the medicine in to his lungs.
