Since your asthma symptoms have worsened, it is very important to consult your doctor before changing medications. The inhaler you mentioned contains two long-acting bronchodilators (indacaterol and glycopyrronium) and is primarily approved for COPD, not asthma. In asthma, using these types of bronchodilators without an inhaled corticosteroid (a preventive steroid) is not recommended and can be unsafe, as it does not treat the underlying airway inflammation. For your safety, please do not use this medication for your asthma. Your doctor will evaluate your worsening symptoms and prescribe a safe, effective controller inhaler tailored specifically for asthma.
