Formoterol 6 mcg + Budesonide 200 mcg is a combination inhaler used for managing asthma and Chronic Obstructive Pulmonary Disease (COPD) by relaxing airways (formoterol) and reducing inflammation (budesonide), making breathing easier and preventing attacks, but must be used as prescribed and not stopped abruptly. It treats symptoms like wheezing and shortness of breath, but isn't for immediate relief of a sudden attack.
