USES: This medication is used to prevent asthma attacks. It is not effective in treating an attack once it begins. Cromolyn is also used just before exercising to minimize breathing problems and before exposure to pollutants or substances that cause allergic reactions/breathing problems.

HOW TO USE: The capsules are NOT to be swallowed. The contents of the capsule are inhaled using a special inhaler. You should receive an instruction sheet on the proper use of the inhaler device. Make sure you understand how to use it. Rinse your mouth after using the inhaler to help prevent dryness and relieve throat irritation. This medication works best when the level in your blood is kept at a constant level. Do this by taking each dose at evenly spaced intervals. Do not stop using this medication suddenly without consulting your doctor. Stopping the medication suddenly may lead to worsening of symptoms. If you are using a bronchodilator inhaler to open up the lungs, use it 20 minutes before taking cromolyn. Using the bronchodilator first will allow the cromolyn to penetrate deeper into the lungs for maximum effect. For preventing exercise-induced bronchospasm, take one of the doses before beginning exercise. It may take a few weeks before the full effects of this medication are noticed. Do not use cromolyn sodium after an asthma attack has started; it can make breathing more difficult.
