Theophylline is used to treat or prevent the symptoms of bronchial asthma, chronic bronchitis, emphysema, and other diseases involving constriction of the airways. Theophylline helps to ease the cough, wheezing, shortness of breath, and troubled breathing associated with these conditions by allowing relaxation of the tubes (bronchi) of the airways, thereby permitting increased amounts of air to flow through them.
