Inhaled corticosteroids (ICS) are medications that help reduce inflammation in the airways. They are inhaled directly into the lungs to help control and prevent wheezing symptoms. These medications work by decreasing swelling and mucus production in the airways, making breathing easier.

Bronchodilators are medications that help relax and open up the airways quickly when wheezing occurs. They provide quick relief by relaxing the muscles around the airways, making it easier to breathe. These medications are typically used as needed when symptoms appear.

Episodic Expiratory Wheezing – A respiratory condition that primarily affects young children, characterized by recurring episodes of wheezing sounds during breathing out. The wheezing occurs in distinct episodes with symptom-free periods in between. During an episode, the airways become temporarily narrow, making it harder to breathe and causing a whistling sound when exhaling. The condition often appears in response to viral infections or environmental triggers, and symptoms typically include coughing and breathing difficulties. Some children may experience these episodes particularly during physical activity or at night.
