Budesonide / Formoterol Inhaler (Generic Symbicort®) is a prescription inhaler used to help control asthma and chronic obstructive pulmonary disease (COPD). It combines two medications: budesonide, a corticosteroid that reduces inflammation in the airways, and formoterol, a long-acting beta agonist (LABA) that helps relax the muscles around the airways to improve breathing. Symbicort is used regularly to prevent symptoms like wheezing, shortness of breath, and flare-ups but is not intended for sudden asthma attacks. With consistent use, it helps improve lung function and reduces the frequency of exacerbations.
