About Cromolyn Sodium Inhalation Solution

What is this medication?

Cromolyn sodium inhalation solution is a prescription medication used for the long-term management and prevention of bronchial asthma symptoms. It belongs to a class of drugs known as mast cell stabilizers, which work by preventing the release of natural substances in the body that cause inflammation and narrowing of the airways. Because this medication works as a preventive measure, it is not used to treat sudden or acute asthma attacks that have already started.

This medication is typically prescribed for patients who require regular treatment to control their asthma or to prevent bronchospasm triggered by exercise or exposure to known allergens. It is administered using a nebulizer, which turns the liquid medicine into a fine mist that is inhaled into the lungs. To achieve the best results, the medication must be used consistently as directed by a healthcare provider, even if the patient is currently feeling well and not experiencing active symptoms.

How to read this:plans on the same formulary share tier + PA rules. Your specific plan's copay depends on (a) the tier above, (b) your plan's cost-share for that tier, (c) whether you're in the initial coverage phase or past the 2026 $2,000 out-of-pocket cap. For your exact plan, check its Summary of Benefits or log in to your Medicare.gov account. Copay cards don't apply to Medicare (federal law).
