Can Sleep Aids Cause Night Terrors and Sleepwalking? Important Safety: How a Doctor Helps

Sleep aids can be a helpful tool when you're struggling to fall or stay asleep. But for some people, these medications and supplements have been linked to unusual behaviors at night—most notably night terrors and sleepwalking. Understanding why this happens, how to spot the warning signs, and when to seek medical advice can help you stay safe and get the rest you need.

What Are Sleep Aids?
Sleep aids come in many forms. Some are prescription medications; others are available over-the-counter (OTC) or as supplements. Common categories include:

• Benzodiazepines (e.g., temazepam)
• "Z-drugs" (non-benzodiazepine sedative-hypnotics such as zolpidem, eszopiclone, zaleplon)
• Antihistamines (diphenhydramine, doxylamine)
• Melatonin and melatonin agonists
• Herbal supplements (e.g., valerian, chamomile)

Most sleep aids work by depressing the central nervous system or by mimicking natural sleep-promoting hormones.

What Are Night Terrors and Sleepwalking?
Both night terrors and sleepwalking are classified as NREM (non-rapid eye movement) parasomnias—unusual behaviors that occur during deep (slow-wave) sleep:

• Night terrors involve sudden arousal with intense fear, screaming, rapid heartbeat, and sweating. The person often appears confused and may not remember the event in the morning.
• Sleepwalking (somnambulism) involves getting up and walking around while still asleep. Actions range from harmless wandering to potentially dangerous activities like opening doors or cooking.

Unlike nightmares, parasomnias usually occur early in the night, during deep sleep, and the person remains partially unconscious.

How Can Sleep Aids Trigger Parasomnias?
Though the exact mechanisms aren't fully understood, sleep aids can:

• Alter Sleep Architecture – Many drugs increase light sleep and decrease deep sleep or REM sleep, creating instability between stages.
• Cause Brain Disinhibition – By depressing areas of the brain that normally suppress motor activity during sleep, some medications allow the body to move or act out dreams.
• Lead to Complex Sleep Behaviors – The FDA has issued post-marketing warnings for Z-drugs after reports of sleepwalking, sleep-driving, eating, talking on the phone, and even having sex while not fully awake.

Key Evidence and Safety Notices

• Zolpidem (Ambien) and related "Z-drugs" carry FDA warnings about "complex sleep behaviors."
• Case reports have linked benzodiazepines and certain antidepressants to night terrors.
• Antihistamines, while generally safer, can still cause confusion and agitation—especially in older adults.

Risk Factors That Increase Your Chances
Not everyone taking a sleep aid will develop parasomnias. But your risk is higher if you have:

• A personal or family history of parasomnias (sleepwalking, night terrors)
• High dosage or use of multiple sleep medications
• Use of alcohol or other sedatives at the same time
• Stress, sleep deprivation, or an irregular sleep schedule
• Certain medical conditions, such as sleep apnea or restless legs syndrome
• Older age (brain metabolism of drugs slows down)

Signs You May Be Experiencing Sleepwalking or Night Terrors
Watch for:

• Unexplained injuries (bruises, cuts, or burns)
• Finding evidence of nighttime activities (opened doors, moved objects, eaten food)
• Waking up in strange places (living room, front yard)
• Reports from a bed partner of sleep talking, thrashing, or screaming
• Feeling unrefreshed in the morning or daytime fatigue

What to Do If You Suspect a Problem

1. Review Your Medications
   • Check dosages and timing. Taking sleep aids right before getting in bed (instead of hours earlier) may help.
   • Avoid mixing with alcohol, opioids, or other sedatives.
2. Practice Good Sleep Hygiene
   • Keep a consistent sleep schedule.
   • Create a calm bedtime routine (no screens, dim lights, relaxation exercises).
   • Ensure your bedroom is safe—lock doors and windows, remove tripping hazards.
3. Talk to Your Doctor
   • Report any unusual nighttime behaviors right away.
   • Your doctor may lower your dose, switch medications, or suggest non-drug therapies (CBT-I, relaxation techniques).
4. Monitor and Document
   • Keep a sleep diary noting when you take your medication, what time you go to bed, and any nighttime events.
   • Video recording can help your doctor understand what's happening.

When to Seek Immediate Help
Certain symptoms warrant prompt medical attention:

• Injury to yourself or others during a nighttime event
• Confusion or disorientation persisting into the daytime
• New or worsening breathing problems (could indicate sleep apnea)
• Hallucinations, seizures, or other serious neurological symptoms

If you experience any life-threatening or alarming signs, do not wait—call emergency services or go to the nearest hospital.

Summary and Next Steps
Sleep aids can be effective for short-term insomnia, but they're not without risks. In some people, especially those with certain vulnerabilities, these medications can trigger night terrors, sleepwalking, and other complex sleep behaviors. You can reduce your risk by:

• Using the lowest effective dose for the shortest time
• Avoiding alcohol and multiple sedatives
• Maintaining good sleep habits
• Staying alert to warning signs and reporting them early

Always keep an open line of communication with your healthcare provider. If you're experiencing sleepwalking, night terrors, or any unusual nighttime behaviors—especially if they lead to injury—speak to a doctor immediately. Your safety and well-being depend on it.
