Medicines known as OTC inhaler are available without a prescription and are usually used to treat moderate asthma symptoms or sporadic respiratory problems. These inhalers typically contain bronchodilators, such as racepinephrine or epinephrine, which relax the muscles in the airways to increase lung airflow. Primatene Mist is a popular example that is accessible in certain nations. Although over-the-counter inhalers can assist with wheezing, chest tightness, and shortness of breath, they are not meant for long-term asthma treatment.
