Duralyn Cr 200 Mg Capsule is used for the long-term management of asthma and COPD in adults, helping to relax airway muscles and prevent bronchospasm to improve breathing.
It contains theophylline in a controlled-release form. Take it at the same time each day as prescribed. Avoid alcohol and excess caffeine during treatment.
Quitting smoking, avoiding known triggers and keeping to all monitoring appointments (including blood theophylline level checks) support better respiratory health alongside this medicine.
Tell your doctor about any heart conditions, liver disease, seizure history or peptic ulcers before starting, and about all other medicines, as theophylline has many drug interactions. Report a fast or irregular heartbeat, severe nausea or restlessness.
