A red asthma inhaler typically refers to a type of inhaler containing a medication for long-term asthma control, such as a corticosteroid. These inhalers help reduce inflammation in the airways, making them less sensitive and less likely to react to asthma triggers. The red color often distinguishes it from rescue inhalers, usually blue and containing fast-acting medication for immediate relief during an asthma attack. If you have an inhaler with a different medication or function, following your healthcare provider's instructions on how and when to use it is essential.
