A blue asthma inhaler typically contains a short-acting beta-agonist (SABA) like albuterol (also known as salbutamol). This type of inhaler is commonly referred to as a "rescue inhaler" or "reliever inhaler" because it is used to provide quick relief from asthma symptoms such as wheezing, shortness of breath, and chest tightness. https://www.genericvilla.com/product/blue-inhaler/
