Available by prescription only, cromolyn inhalation (Intal®) is a drug used to prevent asthma attacks. The medicine 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). The inhaler is used by some people on a regular basis, while others use it just before exercising to prevent exercise-induced asthma attacks or other asthma attacks due to predictable causes.
It should be noted that cromolyn inhalers are no longer being manufactured. After pharmacies deplete their current supplies, these devices will no longer be sold. Therefore, if you are currently using this inhaler, contact your healthcare provider about switching to a different asthma medication.
