What should I watch for while using this medicine?
Visit your doctor or health care professional for regular checks on your progress. Keep a regular sleep schedule by going to bed at about the same time each night. Avoid caffeine-containing drinks in the evening hours. When sleep medicines are used every night for more than a few weeks, they may stop working. Talk to your doctor if you still have trouble sleeping.
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. Serious injuries or death have occurred in rare cases. Stop the medicine. Call your doctor right away if you find out you have done any of these activities. Do not take this medicine if you have used alcohol that evening or before bed or taken another medicine for sleep. The risk of doing these sleep-related activities will be increased.
Do not take this medicine 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.
After you stop taking this medicine, you may have trouble falling asleep. This is called rebound insomnia. This problem usually goes away on its own after 1 or 2 nights.
