Asthmanefrin is used for the temporary relief of mild intermittent asthma symptoms in adults and children, including wheezing, chest tightness, shortness of breath, and bronchospasm. It is not intended for severe asthma attacks or as a substitute for controller medications.
Asthmanefrin contains racepinephrine, an adrenergic agonist that stimulates beta-2 adrenergic receptors in the bronchial smooth muscles. This stimulation causes bronchodilation (relaxation of the airway muscles), allowing easier airflow and relieving symptoms like wheezing and shortness of breath.
This medication is for intermittent, mild asthma symptom relief only and should not replace prescribed daily controller medications. It may cause side effects such as increased heart rate, tremor, nervousness, or insomnia. Patients should seek emergency care for severe symptoms and consult their healthcare provider about proper asthma management.
