What is this medicine used for?

Cromolyn is a medicine used to prevent asthma symptoms. You take this medicine every day, even when you are not having symptoms. This medicine is called a controller medicine because when it’s taken regularly every day, it helps to control symptoms.

Cromolyn does not give quick relief of wheezing in acute asthma attacks. For acute attacks, you need a different type of medicine called a reliever.

Asthma symptoms are caused by 2 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.

Asthma symptoms often start after exposure to a trigger. Asthma triggers can include pollen, animals, mold, colds, exercise, cold air, and air pollutants. It’s important to know what things trigger your asthma symptoms so that you can try to avoid those things or take your reliever medicine before being around a trigger. You should keep reliever medicine with you at all times in case you have an asthma attack.

How does it work?

When you are exposed to something that triggers your asthma symptoms, it causes swelling and irritation in the airways. Cromolyn helps to prevent asthma symptoms by blocking this allergic response to triggers. When you have less swelling, you will have fewer symptoms and be able to breathe better.

Cromolyn is commonly given with a nebulizer. A nebulizer is a machine that you can use at home. Medicine is mixed with liquid and the machine forms a mist. You breathe in the mist to help get the medicine into your lungs.
