What Is Cromolyn Inhalation?

Cromolyn inhalation (Intal®) is a prescription medication used to prevent asthma attacks. It comes in two forms: an inhaler and a nebulizer solution, which is inhaled using a nebulizer (a device that changes liquid medications into fine droplets that are inhaled into the lungs).
It should be noted that cromolyn inhalers are no longer being manufactured. There will be no cromolyn inhalers available after pharmacies deplete their current supplies. If you are using a cromolyn inhaler, be sure to contact your healthcare provider about switching to a different medication.
