COPD Home > Problems With Theophylline

For the most part, people experience a safe, effective treatment process with theophylline. Problems, however, are possible, which is true with any drug. In clinical studies, common side effects included nausea, headaches, and vomiting. Fortunately, such reactions are usually mild and easily treated.
However, there are some potentially serious, even life-threatening, problems with theophylline to be aware of. These include allergic reactions, a worsening of breathing problems, and seizures. People with certain medical conditions may be at a higher risk of adverse reactions than others, so make sure your healthcare provider knows about any other medical conditions you have in addition to COPD or asthma, and has a complete list of all your medications, including vitamins and supplements.
