OTC inhaler are non-prescription drugs that provide brief relief for minor asthma symptoms such wheezing, coughing, and shortness of breath. These inhalers can be acquired without a doctor's prescription and are commonly used by people who have occasional breathing problems. Common active components include epinephrine and racepinephrine, which expand the airways and make breathing easier. While OTC inhalers can give temporary relief, they are not a replacement for prescription drugs or long-term asthma management. It is critical to use them with caution, since excessive or inappropriate use might result in side effects and disguise more serious respiratory disorders.
