It is important that your doctor check the progress of you or your child at regular visits. This will allow your doctor to see if the medicine is working properly and to decide if you should continue to take it. Blood and other laboratory tests may be needed to check for unwanted effects. If your or your child's condition does not improve, or if it becomes worse, discuss this with your doctor.
