What should I watch for while using this medicine?

Visit your doctor or health care professional for regular checks on your progress. This medicine is for short-term periods of use. If you have been taking it regularly for some time, do not stop suddenly or you may get severe side effects. Ask your doctor or health care professional for advice. If you are taking this medicine for insomnia, talk to your doctor if you still have trouble sleeping within 7 to 10 days of using this medicine. This may mean there is another cause for your sleep problems.

After taking this medicine for sleep, you may get up out of bed while not being fully awake and do an activity that you do not know you are doing. The next morning, you may have no memory of the event. Activities such as driving a car ("sleep-driving"), making and eating food, talking on the phone, sexual activity, and sleep-walking have been reported. Call your doctor right away if you find out you have done any of these activities. Do not take this medicine if you drink alcohol or have taken another medicine for sleep, since your risk of doing these sleep-related activities will be increased.

If this medicine is being used for insomnia, do not take it unless you are able to stay in bed for a full night (7 to 8 hours) before you must be active again. You may have a decrease in mental alertness the day after use, even if you feel that you are fully awake. Tell your doctor if you will need to perform activities requiring full alertness, such as driving, the next day. Do not stand or sit up quickly after taking this medicine, especially if you are an older patient. This reduces the risk of dizzy or fainting spells.

If you or your family notice any changes in your behavior, such as new or worsening depression, thoughts of harming yourself, anxiety, other unusual or disturbing thoughts, or memory loss, call your doctor right away.
