What is this medicine used for?

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 two different problems in the airways:

  • One problem is that the tiny muscles around the airways tighten up, which causes shortness of breath, cough, wheezing, and sometimes chest tightness.
  • The other problem is redness, 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, reflux, smoke, 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 have access to reliever medicine at all times in case of an asthma attack.

How does it work?

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 an electrically powered machine that your child can use at home, or if battery operated, anywhere. Medicine is mixed with liquid and the machine forms a mist. Your child breathes in the mist to help the medicine get in to the lungs.

What else do I need to know about this medicine?

  • Follow the directions that come with your child’s medicine, including information about food. Ask for written information to take home. Tell your healthcare provider or pharmacist if you need information in a different language or larger type.
  • Make sure you know how and when your child needs to take the medicine. Your child should not take more or less than he or she is supposed to take.
  • Try to get all of your child’s prescriptions filled at the same place. Your pharmacist can help make sure that all of your child’s medicines are safe to take together.
  • Keep a list of your child’s medicines with you. Tell your child's healthcare provider and pharmacist about all the prescription and nonprescription medicines, natural remedies, vitamins, and supplements your child takes.
  • Many medicines have side effects. A side effect is a symptom or problem that is caused by the medicine. Ask your child’s healthcare provider or pharmacist to review the side effects that Cromolyn may cause and what you should do if your child has side effects.

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.
