What does this medicine do?
Cromolyn reduces airway inflammation by blocking allergic response. It is taken daily to prevent symptoms, NOT to treat acute attacks.
This is a long-term control medicine, also called a controller. It does not immediately open the airways. It does not provide immediate relief for wheezing or asthma attacks. It may prevent asthma symptoms when taken before being exposed to an asthma trigger such as exercise, pollen, animals, or cold air. This medicine is not the first choice to treat mild asthma. It may be used along with other medicines if needed.
For acute asthma attacks, your child will need a quick-relief medicine, also called a reliever.
How is it taken?
Cromolyn is used with a nebulizer.
What is the usual dose?
Cromolyn is usually taken 3 to 4 times a day. Extra doses may be needed before exercise or exposure to allergens.
Your child should take the medicine as prescribed by your healthcare provider.
What side effects can this drug cause?
Side effects are rare. Your child may have a dry mouth, cough, or irritated throat.
What special instructions should be followed?
To prevent symptoms of asthma, cromolyn should be taken regularly several times a day. It can be taken 15 minutes before exercise or exposure to cold air or allergens to prevent symptoms.
