What should I watch for while using this medication?

Visit your care team 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 medications are used every night for more than a few weeks, they may stop working. Talk to your care team if you still have trouble sleeping.

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. Stop the medication and 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.

Do not take this medication 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 care team 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 medication, 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 care team right away.

After you stop taking this medication, you may have trouble falling asleep. This is called rebound insomnia. This problem usually goes away on its own after 1 or 2 nights.

What side effects may I notice from receiving this medication?

  • Change in vision such as blurry vision, seeing halos around lights, vision loss
  • CNS depression—slow or shallow breathing, shortness of breath, feeling faint, dizziness, confusion, difficulty staying awake
  • Mood and behavior changes—anxiety, nervousness, confusion, hallucinations, irritability, hostility, thoughts of suicide or self-harm, worsening mood, feelings of depression
  • Unusual sleep behaviors or activities you do not remember such as driving, eating, or sexual activity
