Are Prescription Sleep Pills Safe to Use Long Term?

Prescription sleep pills are designed for short-term use, and their safety over months or years is less well established. Long-term use can bring dependence, tolerance, daytime drowsiness, falls and memory problems, and some of these medicines carry boxed warnings on the label. This article explains how the main types differ, what the risks look like, why stopping on your own can backfire, and which situations need urgent care.

Are prescription sleep pills safe long term?

Prescription sleep pills are designed for short-term use, and their long-term safety is less well established; the risk depends on the drug, the dose, your age and your other medicines. Most prescription sleep medicines were studied and approved for short periods, and the labels for several of them advise reassessing the need for treatment after a short course. Many people end up taking them for far longer, often because the insomnia never got a closer look.

MedlinePlus, from the National Library of Medicine at NIH, describes insomnia as a condition with several possible contributors and several treatment options, including lifestyle changes, talking therapy and medicine. It also notes that sleep medicines can cause side effects. A pill can quiet the symptom while the cause stays untouched, so the long-term question is often "why am I still not sleeping?" as much as "is this pill safe?"

This page focuses on long-term use. If you are asking about melatonin, see the separate article on taking melatonin every night. Clonazepam withdrawal and anticholinergic memory effects also have their own articles.

The main types of prescription sleep medicine

"Sleeping pill" covers several different drug families. Their risks are not identical, so it helps to know which one you take.

Benzodiazepines

Temazepam and triazolam are examples used for sleep. They can cause physical dependence and tolerance, and stopping suddenly can lead to rebound insomnia, anxiety and, in more serious cases, seizures. The boxed warning on labels for this class was updated in 2020 and covers abuse, misuse, addiction, physical dependence, withdrawal reactions and the risks of combining them with opioids.

"Z-drugs"

Zolpidem (Ambien), eszopiclone (Lunesta) and zaleplon (Sonata) act on similar brain receptors but are chemically different from benzodiazepines. In 2019 a boxed warning was added to their labels about complex sleep behaviors such as sleepwalking, sleep driving and cooking or eating while not fully awake, sometimes with no memory afterward. The labels advise stopping the medicine if this happens, so contact your prescriber the same day to plan what comes next, and do not take another dose until you have spoken with them.

Orexin receptor antagonists

Suvorexant (Belsomra), lemborexant (Dayvigo) and daridorexant (Quviviq) block wake-promoting signals rather than sedating broadly. They are newer, so long-term experience is shorter. They are also controlled substances, and they can still cause next-day drowsiness and unusual sleep experiences such as vivid dreams.

Others

Low-dose doxepin and ramelteon are prescribed for sleep too. Some clinicians prescribe trazodone or other sedating medicines off label. Each has its own side-effect profile, and your prescriber or pharmacist can explain the one that applies to you.

What long-term use can do to your body and brain

Several factors contribute to the risks, and the science on some of them is still developing.

• Tolerance. Over time, the same dose may seem to work less well. This is a reason to talk with your prescriber, not a reason to raise the dose yourself.
• Dependence and rebound insomnia. When the medicine wears off or is stopped, sleep can become worse than before for a period. This can make it feel as though you cannot sleep without the pill.
• Daytime impairment. Drowsiness, slowed reaction time and trouble concentrating can persist into the next morning and can affect driving. Zolpidem labels warn about next-morning impairment and recommend lower starting doses, especially for women and older adults, so ask your prescriber what applies to you.
• Falls and injuries. Sedating medicines are associated with unsteadiness and falls, particularly in older adults and when getting up at night.
• Memory and thinking. Some people notice memory gaps or fogginess. Whether long-term use affects thinking over years is still being studied, so a single explanation should not be assumed.
• Mood. Insomnia and depression are closely linked. A sleep medicine can sometimes mask a mood problem that needs its own treatment.

Why mixing sleep pills with other substances matters

Sleep medicines slow the brain's activity. Combined with alcohol, opioid pain medicines or other sedatives, breathing can slow dangerously. MedlinePlus pages on safe opioid use, opioid overdose and pain relievers describe slowed breathing as a danger of opioids, and the boxed warning on benzodiazepines addresses combining them with opioids. Talk with your prescriber or pharmacist about avoiding these combinations. If you have already combined them and feel unusually drowsy, confused or are breathing slowly, treat it as an emergency and call 911.

Over-the-counter sleep aids can add to this. Many contain diphenhydramine or doxylamine, which are sedating antihistamines. Taking one on top of a prescription sleep pill can increase sedation and may cause confusion, dry mouth or urinary trouble. Professional guidance for older adults commonly advises avoiding first-generation antihistamines such as diphenhydramine, so ask your pharmacist or prescriber first.

Tell your prescriber and pharmacist about everything you take, including supplements and cannabis products. The MedlinePlus overview of medicines offers general guidance on safe use and keeping a medicine list.

Who needs extra caution

• Older adults. Falls, confusion and next-day sedation are a particular concern. Ask the prescriber whether the medicine is appropriate for your age and other conditions.
• People who are pregnant or breastfeeding. Do not start or stop a sleep medicine without talking to your obstetric clinician.
• People with breathing conditions or sleep apnea. Sedatives may worsen breathing during sleep. Untreated sleep apnea can itself be the cause of poor sleep.
• People with a history of substance use or depression. Dependence and mood effects deserve a more careful conversation.
• People who drive, operate machinery or work night shifts. Next-day impairment can matter more.

Why stopping on your own can be risky

If you have taken a sleep medicine nightly for a long time, do not stop it abruptly or change the timing or amount without talking to the prescriber. The one situation that differs is a complex sleep behavior on a z-drug, where the label advises stopping and contacting the prescriber, described in the section below. Stopping some of these medicines suddenly can cause rebound insomnia, anxiety, tremor, sweating and, with benzodiazepines, seizures; abrupt discontinuation is a labeled risk for that class. Prescribers usually reduce the dose gradually, and the schedule depends on the drug, how long you took it and your health. A taper is directed by your clinician, and CBT-I can support sleep while it happens.

If you are already having tremor, sweating or severe anxiety after a missed dose or dose change, contact your prescriber or pharmacist the same day. Do not wait for a callback if symptoms are getting worse. If someone recently stopped or cut back a sleep medicine and has a seizure, confusion, hallucinations, severe agitation, a racing heart or fever, call 911 or go to the emergency room, because these can signal serious withdrawal.

The same caution applies in reverse. If your medicine seems to work less well, ask about the options rather than adding doses or a second sedating product.

What to try alongside, or instead of, long-term pills

Treating the cause is often central. Clinicians combine your history, examination and sometimes testing to look for contributors such as:

• Sleep apnea or restless legs
• Depression or anxiety
• Pain, reflux, frequent urination or hot flashes
• Medicines that disrupt sleep, including some stimulants, steroids and decongestants
• Caffeine, alcohol and irregular schedules

Cognitive behavioral therapy for insomnia (CBT-I) is a structured program that targets thoughts and habits that keep insomnia going. Professional insomnia guidelines generally recommend CBT-I as an initial treatment for chronic insomnia in adults, and it can be delivered by a trained clinician or through supervised digital programs. Outcomes vary, and it usually takes several weeks of practice.

Basic sleep habits may also help: a regular wake time, a dark and cool bedroom, limited screens and caffeine late in the day, and getting out of bed when you cannot sleep rather than lying awake.

Questions to bring to your prescriber

• How long was this medicine meant to be used for me?
• Could another condition or another medicine be keeping me awake?
• Is it appropriate to taper, and how would we do it safely?
• Are any of my other medicines or alcohol use a problem with this one?
• Would CBT-I or a sleep evaluation be appropriate?

Signs the medicine may be causing a problem

Complex sleep behaviors such as sleepwalking, sleep driving or eating with no memory afterward are a labeled reason to stop a z-drug. If this happens while taking zolpidem (Ambien), eszopiclone (Lunesta) or zaleplon (Sonata), the labels advise stopping the medicine, so contact your prescriber the same day to plan what comes next, and do not take another dose until you have spoken with them. For other sleep medicines, especially benzodiazepines, call your prescriber or pharmacist the same day before stopping, because stopping suddenly can cause withdrawal or seizures. Other signals include repeated falls, new memory gaps, heavy morning drowsiness, new or worsening low mood, or needing the medicine to feel normal.

Very slow or shallow breathing, being unable to wake someone, a seizure, confusion or hallucinations after stopping, or thoughts of ending your life are emergencies and are listed in the box on this page. Call 911 first if the person is unresponsive, very hard to wake, has trouble breathing or a seizure, or may have overdosed on purpose. If someone is awake and alert after a possible large dose or a mix with alcohol or opioids, call Poison Control at 1-800-222-1222 right away, and call 911 if any symptoms appear. If opioids may be involved and naloxone is available, give it while waiting for help; it will not reverse a benzodiazepine or z-drug. Poison Control is free, open 24 hours a day, and can advise on any suspected overdose or exposure.
