The red asthma inhaler you’re referring to is likely a type of reliever inhaler, commonly known as a “rescue” inhaler. These inhalers typically contain a fast-acting medication that helps to quickly relieve asthma symptoms such as wheezing, coughing, shortness of breath, and chest tightness. One of the most common medications found in these inhalers is albuterol. Red inhalers are often color-coded to indicate specific medications used for managing respiratory conditions such as asthma, chronic obstructive pulmonary disease (COPD), and other lung diseases. These inhalers typically contain bronchodilators, which help to open up the airways and make breathing easier.
