The “red asthma inhaler” you’re referring to is likely a type of rescue inhaler that contains a medication called albuterol. This medication is commonly used to quickly relieve asthma symptoms such as wheezing, shortness of breath, and chest tightness by opening up the airways in the lungs. It’s typically used as needed during asthma attacks or when experiencing symptoms. If you have asthma and are prescribed a red inhaler, it’s important to follow your healthcare provider’s instructions on how and when to use it.
