Why is this medication prescribed?
Theophylline is used to prevent and treat wheezing, shortness of breath, and difficulty breathing caused by asthma, chronic bronchitis, emphysema, and other lung diseases. It relaxes and opens air passages in the lungs, making it easier to breathe.
This medication is sometimes prescribed for other uses; ask your doctor or pharmacist for more information.
How should this medicine be used?
Theophylline comes as a tablet, capsule, solution, and syrup to take by mouth. It usually is taken every 6, 8, 12, or 24 hours. Follow the directions on your prescription label carefully, and ask your doctor or pharmacist to explain any part you do not understand. Take theophylline exactly as directed. Do not take more or less of it or take it more often than prescribed by your doctor.
Take this medication with a full glass of water on an empty stomach, at least 1 hour before or 2 hours after a meal. Do not chew or crush the extended-release (long-acting) tablets; swallow them whole. Extended-release capsules (e.g., Theo-Dur Sprinkles) may be swallowed whole or opened and the contents mixed with soft food and swallowed without chewing.
Theophylline controls symptoms of asthma and other lung diseases but does not cure them. Continue to take theophylline even if you feel well. Do not stop taking theophylline without talking to your doctor.
