Theophylline primarily treats asthma and chronic obstructive pulmonary disease (COPD). It relaxes the muscles around your airways, making it easier to breathe. This is achieved by blocking the action of phosphodiesterase, an enzyme that constricts the airways.
For asthma, theophylline can help prevent and treat symptoms like wheezing, coughing, and shortness of breath. In COPD, it can improve lung function and reduce the frequency of exacerbations. Dosage varies significantly depending on individual factors and should always be determined by a physician.
While beneficial, theophylline requires careful monitoring due to its narrow therapeutic range. Blood tests regularly check theophylline levels to ensure they remain within the safe and effective range, minimizing the risk of side effects.
Common side effects include headache, nausea, and stomach upset. More severe side effects, while less frequent, necessitate immediate medical attention. Always discuss potential side effects and their management with your doctor.
Before starting theophylline, inform your doctor about any other medications you’re taking, especially those metabolized by the liver, as interactions may occur. Also disclose any existing heart conditions, liver problems, or stomach ulcers.
Remember, theophylline is a prescription medication. Never self-medicate; consult your doctor for proper diagnosis and treatment. They will assess your individual needs and determine the appropriate dosage and treatment plan.
