Summary
Cromolyn is a medication used to treat asthma. It is a slow-acting drug, meaning that it does not work as a rescue medication, but is instead used for long-term maintenance therapy of asthma. It can also be used to treat seasonal allergies, or allergic rhinitis. If cromolyn is suddenly stopped, it might result in rebound bronchospasm. To avoid this, the medication should be tapered off slowly.
