Answer:

A rescue inhaler dispenses medication called a bronchodilator, which expands or dilates the airways, making it easier to breathe. It is used to relieve or stop the symptoms of an asthma attack. Rescue inhalers also help clear mucus from the lungs. As the airways open, the mucus moves more freely and can be coughed out more easily. Rescue inhalers should be used as soon as a person feels their asthma beginning to flare up.
