Uses for Theo-Time
Theophylline is used together with other medicines to treat the symptoms of asthma, bronchitis, emphysema, and other lung diseases.
Theophylline belongs to a group of medicines known as bronchodilators. Bronchodilators are medicines that relax the muscles in the bronchial tubes (air passages) of the lungs. They relieve cough, wheezing, shortness of breath, and troubled breathing by increasing the flow of air through the bronchial tubes.
This medicine is available only with your doctor's prescription.
Before using Theo-Time
