Asthalin Inhaler is a short-acting bronchodilator that treats asthma and chronic obstructive pulmonary disease (COPD). It contains Salbutamol (100 mcg), which relaxes the airway muscles and facilitates breathing. This inhaler gives immediate relief from symptoms such as wheezing, shortness of breath, and chest tightness, making it a vital rescue inhaler for unexpected asthma attacks or exercise-induced bronchospasm. Asthalin works quickly and provides temporary relief, but it is not a long-term asthma management treatment. Mild tremors, headaches, throat discomfort, and a rise in heart rate are all common adverse effects. To avoid any adverse effects, take the inhaler exactly as prescribed by a doctor and avoid excessive use.
