One common bronchodilator that helps with breathing problems brought on by asthma and chronic obstructive pulmonary disease (COPD) is salbutamol.  Breathing becomes easier as a result of the airway muscles being relaxed.  Local laws determine whether over the counter salbutamol is available.  Because of possible adverse effects like tremors, elevated heart rate, and dizziness, it is required to have a prescription in several countries.  For emergency use, certain areas do, nevertheless, permit restricted OTC access.  Before using over-the-counter salbutamol, it is crucial to adhere to the specified dosage and speak with a healthcare professional, particularly for those who have high blood pressure or cardiac issues.  Overuse or misuse can pose major health concerns, therefore getting the right medical advice is essential.
