Shortness of breath? Wheezing? A person who suffers from bronchial asthma has very sensitive air passages (bronchi) that may be affected by a number of different things called triggers. These triggers include food, medicine, pets, smoke or other irritants in the air, the common cold, and exercise. When exposed to a trigger, a person may experience shortness of breath, tightness in the chest, or wheezing. Over-the-counter (OTC) asthma medicines, also known as bronchodilators, are used to help relieve breathing problems caused by bronchial asthma.
Asthma medicines, like all OTC medicines, contain certain active ingredients that make them work in the human body. The product’s active ingredients, including how much of a substance is in each dose, are listed first on the Drug Facts label.
