What should I watch for while using this medication?

If you are already being treated for insomnia use this medication only by your care team's direction. This medication may interfere with other treatments. See your care team if your symptoms do not get better or if they get worse.

You may get drowsy or dizzy. Do not drive, use machinery, or do anything that needs mental alertness until you know how this medication affects you. Do not stand or sit up quickly, especially if you are an older patient. This reduces the risk of dizzy or fainting spells. Alcohol may interfere with the effect of this medication. Avoid alcoholic drinks.

After taking this medication, you may get up out of bed and do an activity that you do not know you are doing. The next morning, you may have no memory of this. Activities include driving a car ("sleep-driving"), making and eating food, talking on the phone, sexual activity, and sleep-walking. Serious injuries have occurred. Call your care team right away if you find out you have done any of these activities. Do not take this medication if you have used alcohol that evening. Do not take it if you have taken another medication for sleep. The risk of doing these sleep-related activities is higher.
