Theophylline er coupon information is not available. Theophylline extended-release (ER) is a medication used to treat respiratory diseases such as emphysema, chronic bronchitis, and asthma. It works by relaxing the muscles around the airways in the lungs, making it easier to breathe.
How does Theophylline ER work?
Theophylline ER is a bronchodilator. It belongs to a class of drugs called xanthine derivatives. These drugs relax the smooth muscles of the bronchial tubes, which are the airways in the lungs. By relaxing these muscles, theophylline ER helps to open up the airways, allowing more air to flow in and out of the lungs. This can relieve symptoms like wheezing and shortness of breath.
What conditions is Theophylline ER prescribed for?
Theophylline ER is primarily used for the management of symptoms associated with chronic obstructive pulmonary disease (COPD), which includes chronic bronchitis and emphysema, and also for the treatment of asthma. It is typically used when other treatments have not been sufficiently effective.
What are the potential side effects of Theophylline ER?
Like all medications, theophylline ER can cause side effects. Common side effects may include nausea, vomiting, headache, dizziness, restlessness, and insomnia. More serious side effects can occur, especially if blood levels of the drug become too high. These can include seizures, irregular heartbeat, and even heart attack. It is crucial to take the medication exactly as prescribed and to report any concerning symptoms to a healthcare provider.
Who manufactures Theophylline ER?
Several pharmaceutical companies may manufacture or distribute theophylline ER. Specific brand names and manufacturers can vary by region and over time. Information on current manufacturers and available products can typically be found through pharmacies and healthcare providers.

The choice of treatment depends on the specific condition, its severity, and individual patient factors.
