The red inhaler for asthma is called Symbicort, which is a combination inhaler containing two medications: budesonide and formoterol. Budesonide is a corticosteroid that helps reduce inflammation in the airways, while formoterol is a bronchodilator that helps relax the muscles in the airways, making it easier to breathe. Symbicort is used for treating asthma symptoms and preventing asthma attacks. It is also used for the maintenance treatment of moderate to severe chronic obstructive pulmonary disease (COPD), including emphysema and chronic bronchitis. It's important to note that the color-coding system for asthma inhalers is not consistent across all medications. While some inhalers comply with the color-coding system, others do not. The color of the inhaler can vary depending on the brand and type of medication it contains. Therefore, it's always important to read the medication label and confirm that you are using the correct inhaler.
