What are sleep medications?

Sleep medications (hypnotics) are prescription drugs used to help people fall asleep or stay asleep. They are generally considered alongside, or after, non-medication approaches for insomnia.

What they’re used for

Short-term or, for some medications, longer-term treatment of insomnia, as determined by a prescriber.

How they work

  • “Z-drugs” (zolpidem, eszopiclone, zaleplon) enhance GABA, a calming brain chemical.
  • Orexin receptor antagonists (suvorexant, lemborexant, daridorexant) block orexin, a chemical that promotes wakefulness.
  • Melatonin receptor agonists (ramelteon) act on the body’s sleep-wake signaling.
  • Low-dose doxepin blocks histamine to promote sleep maintenance.
  • Some other medications, such as certain antidepressants, are sometimes used off-label.

How they’re taken

Usually taken shortly before bed, only when you can stay in bed for a full night. Your prescriber and pharmacist will provide specific instructions — this page does not provide dosing guidance.

Common side effects

  • Next-day drowsiness or grogginess
  • Dizziness
  • Headache
  • Unpleasant taste (eszopiclone)

Serious side effects

Complex sleep behaviors (sleepwalking, sleep-driving), memory problems, falls, worsening depression or thoughts of suicide, and severe allergic reactions require prompt medical attention.

Warnings

  • Don’t drive or do activities requiring alertness until you know how the medication affects you the next day.
  • Avoid alcohol and other sedatives.
  • Older adults are more sensitive to side effects such as falls and confusion.

Interactions

Opioids, benzodiazepines, alcohol, antihistamines and other sedating drugs can dangerously increase sedation. Some medications affect how sleep medications are broken down in the body.

Questions to ask your healthcare professional

  • Have we ruled out other causes, such as sleep apnea or depression?
  • Would CBT-I be a good option for me first?
  • How long should I take this medication?
  • What should I do if I feel drowsy the next day?

When to seek professional help

Consider talking with a doctor or licensed mental health professional if symptomslast for more than two weeks, keep coming back, or make it harder to manage work, school, relationships or daily tasks. You don’t need to wait until things feel severe — getting support early often makes things easier.

If you’re thinking about harming yourself or are in immediate danger, call your local emergency number. In the US, call or text 988 (Suicide & Crisis Lifeline).Crisis resources in other countries.

Frequently asked questions

Is melatonin a good alternative to prescription sleep medication?
Melatonin may help with some circadian rhythm problems, such as jet lag, but evidence for chronic insomnia is limited. In the US it is sold as a supplement, so product content can vary. Ask a healthcare professional before using it, especially for children.
Can I take sleep medication every night?
Some medications are intended for short-term use; others are approved for longer use. Whether nightly use is appropriate depends on the medication and your situation — discuss this with your prescriber.
