Tell your healthcare provider right away if you feel like you cannot stay awake during the time you are normally awake or if you feel like you are going to pass out. Your healthcare provider may lower your dose or stop the medication until your symptoms go away. Do not drive, operate machinery, or engage in potentially hazardous activities requiring mental alertness and motor coordination until the sedative effects have gone away and you know how these medications affect you. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.
