Doxofylline is used to manage breathing problems caused by lung disease such as chronic obstructive pulmonary disease (COPD) or asthma.
It is a bronchodilator which helps to treat airflow obstruction by relaxing the airways of the lungs, relieving chest tightness, wheezing, and cough so you can breathe more easily.
