Ephedrine belongs to a class of medications called sympathomimetics. Ephedrine is used for temporary relief of shortness of breath, chest tightness, and wheezing due to bronchial asthma. Ephedrine may also be used for other conditions as determined by your doctor.

Ephedrine is a decongestant and bronchodilator. It works by reducing swelling and constricting blood vessels in the nasal passages and widening the lung airways, allowing you to breathe more easily.
