Theophylline is a medication belonging to the methylxanthine class, commonly used to treat respiratory diseases such as chronic obstructive pulmonary disease (COPD) and asthma. It works by relaxing the muscles in the airways, making it easier to breathe. Theophylline also has mild stimulant effects.

It is administered orally, typically in tablet or capsule form, and sometimes as a liquid. The dosage of theophylline needs to be carefully monitored by a healthcare professional due to its narrow therapeutic index, meaning the difference between an effective dose and a toxic dose is small. Regular blood tests are often required to ensure the drug levels remain within the safe and effective range.

Side effects of theophylline can include nausea, vomiting, headaches, insomnia, and restlessness. More serious side effects, which can occur with higher doses or in sensitive individuals, include rapid heartbeat, seizures, and irregular heart rhythms. It is important for patients to inform their doctor about any other medications they are taking, as drug interactions can occur. Theophylline is not typically the first-line treatment for asthma or COPD due to the availability of newer, safer medications with fewer side effects. However, it remains a valuable option for some patients, particularly when other treatments have not been successful.
