OTC inhaler Supplier is a drug that does not require a prescription and is often used to treat moderate asthma symptoms such wheezing, chest tightness, and shortness of breath. These inhalers often contain active chemicals such as epinephrine or racepinephrine, which operate as bronchodilators by relaxing the airway muscles and enabling more airflow into the lungs. OTC inhalers are designed for short-term, immediate comfort and are not appropriate for long-term asthma management or severe symptoms. While they are convenient, incorrect or excessive use might result in negative effects such as increased heart rate, jitteriness, or high blood pressure. They may also conceal underlying issues that require professional medical attention.
