An inhaler is a medical device used to deliver medication directly into the lungs. It is commonly prescribed for individuals with respiratory conditions such as asthma or chronic obstructive pulmonary disease (COPD). Inhalers can come in different forms, including metered-dose inhalers (MDIs) and dry powder inhalers (DPIs), each designed to help patients breathe easier by providing quick relief from symptoms. Using an inhaler typically involves taking a deep breath while pressing down on the device to release the medication. This allows the medicine to reach the airways effectively. Proper technique is essential for maximizing the benefits of the inhaler and ensuring that the medication works as intended.
