The red asthma inhaler is typically a type of rescue inhaler used to provide quick relief during asthma attacks. It usually contains a medication called albuterol (also known as salbutamol), which helps to open up the airways and alleviate symptoms such as wheezing, shortness of breath, and chest tightness. It's important for individuals with asthma to carry their inhaler with them at all times for immediate use in case of an asthma flare-up.
