OTC inhaler is a non-prescription drug that provides brief relief from minor respiratory symptoms including wheezing, chest tightness, or shortness of breath. These inhalers often contain active chemicals such as epinephrine or racepinephrine, which function as bronchodilators to open the airways and improve breathing. Individuals who suffer from intermittent asthma symptoms or bronchial irritation frequently utilise over-the-counter inhalers. While they provide immediate relief, they are not a long-term cure and should not be substituted for prescribed asthma drugs for chronic or severe problems. Overuse can cause negative effects such as elevated heart rate, tremors, and anxiousness. It is critical to use OTC inhalers exactly as prescribed and to consult a healthcare professional if symptoms continue or worsen.
