Cromolyn is a medicine used to prevent asthma symptoms. This medicine is taken every day, even when your child is not having symptoms. This medicine is called a controller medicine because when it is taken regularly every day, it helps to control symptoms.
Cromolyn does not give quick relief from wheezing in acute asthma attacks. For acute attacks, your child needs a different type of medicine called a reliever.
Asthma symptoms are caused by 2 different problems in the airways:
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 to know what things trigger your child's asthma symptoms. Help your child avoid the things that trigger an asthma attack. Your child should keep reliever medicine with him at all times in case he or she has an asthma attack.
When your child is exposed to something that triggers asthma symptoms, it causes swelling and irritation in the airways. Cromolyn helps to prevent asthma symptoms by blocking this allergic response to triggers. When there is less 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 can use at home. Medicine is mixed with liquid and the machine forms a mist. Your child breathes in the mist to help get the medicine into his or her lungs.
If you have any questions, ask your healthcare provider or pharmacist for more information. Be sure to keep all appointments for provider visits or tests.
