Unusual nighttime activity can be difficult to identify, especially when the person involved has little or no memory of what happened. Ambien, which contains zolpidem, has been associated with complex sleep behaviors that may occur while a person is not fully awake.

Learning about Ambien sleepwalking and sleep driving can help patients and caregivers recognize concerning changes and respond appropriately.

What Symptoms Might Occur?

Potential signs of a complex sleep behavior include:

• Walking around during the night without appearing fully aware.

• Preparing or eating food while not fully awake.

• Leaving the bedroom or home unexpectedly.

• Attempting to drive a vehicle.

• Making phone calls or performing other activities that are not remembered later.

These examples do not establish a diagnosis on their own. However, unusual activity after taking zolpidem should be taken seriously, particularly when the person cannot recall the event.

Why Might Someone Not Remember?

During a complex sleep behavior, a person may not be fully awake or aware of what they are doing. They may appear responsive to others, yet have little or no memory of the episode the next morning.

A lack of memory does not mean the event was harmless. The person may have been exposed to traffic, falls, burns, or other hazards.

What Should Family Members Do?

If you witness unusual nighttime behavior after someone has taken Ambien, prioritize immediate safety. Avoid confrontation that could escalate the situation, and seek emergency help if the person is in danger or injured.

After the immediate situation is safe, the person should stop taking the medicine and contact their healthcare professional immediately, in line with FDA guidance.

Could It Be Ordinary Sleepwalking?

Sleepwalking can have different causes, so it is not possible to determine the cause from behavior alone. The timing of the episode, medicines used, medical history, and other symptoms can help a clinician assess what happened.

Conclusion

Unexplained nighttime activity, particularly when accompanied by memory loss, deserves prompt attention when zolpidem is involved. Do not dismiss a possible medication-related episode simply because the person seems fine the next morning.
