Theophylline Er

Theophylline ER comes in the form of an intravenous solution and is used to treat symptoms such as wheezing or shortness of breath caused by asthma, bronchitis, emphysema, and other breathing problems. It works by relaxing muscles in the lungs and chest, making the lungs less sensitive to allergens and other causes of bronchospasm. Do not start or stop smoking without first talking to your doctor. Common side effects may include stomach pain, diarrhea, upset stomach, headache and sweating.
