Ventolin Inhaler (salbutamol sulfate) is a short-acting bronchodilator that relaxes constricted airways. This dry powder inhaler with dosage system offers easy use for quick relief from asthma attacks and exercise-induced symptoms. By relaxing the muscles in your lungs, it increases airflow capacity and reduces breathing difficulties. The effects are noticeable within 5 to 15 minutes and can last up to 4 to 6 hours. To use, remove the protective cap, clean the mouthpiece if necessary, shake the inhaler, hold it upright while taking a deep breath in as you press down on the container, then hold your breath for optimal results.
