Do you also have difficulty breathing, that is, a condition like asthma? Or do you suffer from a long-term lung disease called COPD (Chronic Obstructive Pulmonary Disease)? Then your doctor may have prescribed you a medicine called Theophylline. It comes under various brand names in our country. So, today we will talk exactly, very simply, about what this medicine is, what we should be careful about while using it, and what problems it can cause.
