Asthma inhalers are medical devices used to deliver medication directly into the lungs for individuals with asthma. They help relieve symptoms like wheezing, coughing, and shortness of breath by opening up the airways. There are two main types: rescue inhalers, which provide quick relief during an asthma attack, and maintenance inhalers, which are used daily to prevent symptoms. Inhalers come in various forms, including metered-dose inhalers (MDIs) and dry powder inhalers (DPIs). Proper technique is essential for effective use, ensuring that the medication reaches the lungs. Regular check-ups with a healthcare provider can help manage asthma effectively.
