When you have COPD, it is important that you visit your doctor or nurse regularly so that they can monitor your progress and assess whether a change in treatment is needed. They will carry out a number of tests that will indicate if your symptoms have worsened since your last visit. If your test results show no improvement, or deterioration in your lung function, some changes may be made to your medication to help you manage your daily life and exercise more effectively³,⁴.
