Theophylline dosage for emphysema depends on several factors, including patient age, weight, and overall health. A healthcare professional will determine the appropriate starting dose, typically beginning with a lower amount and gradually increasing it as needed. Common starting doses range from 100-200 mg daily, administered in divided doses, such as twice daily.
Monitoring Theophylline Levels
Regular blood tests are necessary to measure theophylline levels in your blood. This helps ensure the medication is working effectively and prevents potentially harmful side effects. Target therapeutic levels generally fall within 5-15 mcg/mL. Doctors adjust dosage based on these results. Frequent monitoring, especially during initial treatment and after dosage changes, is vital.
Administration and Potential Side Effects
Theophylline is usually taken orally, in tablet or capsule form, with food to minimize stomach upset. Extended-release formulations are available to allow for once-daily or twice-daily dosing. Common side effects include nausea, headache, and insomnia. Report any unusual or severe side effects to your doctor immediately. These may include irregular heartbeat, seizures, or chest pain.
Interactions and Precautions
Theophylline interacts with various medications, including some antibiotics, diuretics, and cimetidine. Inform your doctor about all medications you are taking, including over-the-counter drugs and herbal supplements, to avoid potentially dangerous interactions. Individuals with liver or heart disease may require dose adjustments and careful monitoring.
