Patient Education

Cromolyn Oral Inhalation


Cromolyn oral inhalation is used to prevent the wheezing, shortness of breath, difficulty breathing, coughing, and chest tightness caused by asthma. It also is used to prevent breathing difficulties (bronchospasm) caused by exercise, cold and dry air, or by inhaling substances such as pet dander, pollen, dust mites, or chemicals, such as perfume. It works by preventing the release of substances that cause inflammation (swelling) in the air passages of the lungs.
