By now, you\u2019ve probably heard of ketamine. It\u2019s often described as a \u201cmiracle drug\u201d for people living with major depressive disorder<\/a> (MDD), particularly treatment-resistant depression (TRD) and post-traumatic stress disorder<\/a> (PTSD). [1, 2]<\/sup><\/p>\n\n\n\n

But you may not yet know about ketamine\u2019s potentially significant effects on sleep. This article will explore everything you need to know about ketamine and sleep.<\/p>\n\n\n\n

What is ketamine?<\/strong><\/h2>\n\n\n\n

Ketamine is an anesthetic (tranquilizer) and mental health medication that blocks N-methyl-D-aspartate (NMDA) receptors in the brain. [1]<\/sup>\u00a0Ketamine therapy, meanwhile, is a form of mental health treatment that combines the use of ketamine with therapy sessions, under doctor supervision.<\/p>\n\n\n\n

Because of its effects on NMDA, ketamine \u201ccan make one experience dissociation and sedation, which can be therapeutic,\u201d says Niloufar Esmaeilpour, founder and clinical director of Lotus Therapy & Counseling Centre<\/a> in British Columbia, Canada.<\/p>\n\n\n\n

How does ketamine work?<\/strong><\/h2>\n\n\n\n

NMDA is responsible for allowing neurons in the synapses within your brain to communicate and work in concert with the perception of pain and making memories. [3]<\/sup><\/p>\n\n\n\n

By blocking NMDA, ketamine has both sedative and stimulatory effects. This means it can have significant effects on your sleep. [4]<\/sup><\/p>\n\n\n\n

Ketamine historically has been administered intravenously (IV). [5]<\/sup><\/p>\n\n\n\n

\u201cHowever, many doctors now prefer intramuscular injection as it is easier to dose and administer and causes fewer adverse effects,\u201d says Jared L. Ross<\/a>, DO, president and founder of the medical education and consulting firm EMSEC, LLC, in Sedalia, Mo.<\/p>\n\n\n\n

Ross explains that ketamine also can be administered via lozenges that are dissolved under the tongue, or via rectal suppositories.<\/p>\n\n\n\n

Ketamine should be taken only under the guidance of a medical professional.<\/p>\n\n\n\n

\u201cCareful medical assessment and a review of medical history with the attending health provider have to be done before treatment with ketamine,\u201d says Esmaeilpour.<\/p>\n\n\n\n

Ketamine and sleep: What\u2019s the connection?<\/strong><\/h2>\n\n\n\n

\u201cKetamine has been shown to have significant negative short-term effects on sleep,\u201d says Ross, \u201cincluding increased time to fall asleep<\/a>, decreased total sleep, decreased REM sleep<\/a>, decreased slow-wave sleep<\/a>, and decreased sleep quality<\/a>.\u201d [6]<\/sup><\/p>\n\n\n\n

For this reason, he recommends that people with sleep disturbances avoid ketamine after 12 pm.<\/p>\n\n\n\n

Ketamine and depression<\/strong><\/h3>\n\n\n\n

Ketamine has rapid-acting antidepressant activity, Esmaeilpour says.<\/p>\n\n\n\n

According to a review of the research on ketamine reported in the journal Progress in Neurobiology<\/em>, \u201cThe discovery of ketamine\u2019s rapid antidepressant<\/a> effects is arguably one of the most substantial advances in modern psychiatry.\u201d [7]<\/sup><\/p>\n\n\n\n

The review notes that, in contrast to conventional antidepressant drugs that may require months of daily use before seeing results, a single infusion of ketamine \u201coften relieves symptoms in mere hours\u201d and its antidepressant effects typically last for up to a week. [7]<\/sup><\/p>\n\n\n\n

Ketamine and sleep disorders<\/strong><\/h3>\n\n\n\n

Because depression tends to alter a person\u2019s sleeping pattern, leading to problems like insomnia<\/a> or hypersomnia<\/a> (excessive sleep), Esmaeilpour adds that ketamine\u2019s sedative characteristics \u201cmight be sleep-promoting for some patients.\u201d<\/p>\n\n\n\n

She cautions, however, that \u201cits effects on sleep architecture, such as the distribution of sleep stages across the night, vary widely among individuals.\u201d<\/p>\n\n\n\n

When depression is the primary reason for poor sleep, a 2023 literature review<\/a> states ketamine can improve sleep. [8]<\/sup> But for those with such sleep disorders<\/a> as narcolepsy<\/a> or sleep apnea<\/a>, Ross says ketamine is \u201cunlikely to help.\u201d<\/p>\n\n\n\n

Esmaeilpour says ketamine is \u201cgenerally not a good idea\u201d with regard to sleep disorders.<\/p>\n\n\n\n

\u201cSleep apnea relates to respiratory functions,\u201d she says, \u201cwhereas narcolepsy is all about neurological functions, and the primary effects of ketamine do not deal with the underlying causes of these two sleep disorders.\u201d [9]<\/sup><\/p>\n\n\n\n

Ketamine and insomnia<\/strong><\/h3>\n\n\n\n

\u201cKetamine may worsen insomnia in most patients by decreasing slow-wave and REM sleep, and decreasing sleep quality,\u201d Ross says. [6]<\/sup> \u201cHowever, in patients with insomnia due to major depressive disorder (MDD), specifically treatment-resistant depression (TRD) and post-traumatic stress disorder (PTSD), ketamine can be very helpful.\u201d\u00a0[2]<\/sup><\/p>\n\n\n\n

Esmaeilpour adds that ketamine may give some temporary relief to insomnia due to its sedative effect\u2014but its long-term effects on sleep patterns are unpredictable, making it a double-edged sword. [8, 10]<\/sup><\/p>\n\n\n\n

She adds that some people may get \u201crebound insomnia\u201d when the drug effects wear off. [11]<\/sup><\/p>\n\n\n\n

Ketamine and REM sleep<\/strong><\/h3>\n\n\n\n

Ross says ketamine decreases REM sleep and slow-wave sleep, the deepest level of non-REM sleep. [6]<\/sup><\/p>\n\n\n\n

\u201cThe effects of ketamine on REM sleep are important,\u201d Esmaeilpour says, \u201cbecause this stage is essential to emotional and cognitive health. It has been noted that ketamine depresses the REM stage of sleep during the initial hours after administration.\u201d<\/p>\n\n\n\n

This could serve to interrupt the normal sleep cycle and affect the restorative properties of sleep, notes Esmaeilpour, \u201cthough the clinical significance of these effects does vary.\u201d<\/p>\n\n\n\n

Risks of ketamine<\/strong><\/h2>\n\n\n\n

It\u2019s important to emphasize that ketamine is a powerful drug and should only be used under medical supervision. It can have severe adverse effects.<\/p>\n\n\n\n

\u201cKetamine can cause significant nausea and vomiting,\u201d Ross says, especially when administered by IV or in lozenges under the tongue. [12]\u00a0<\/sup>\u201cSome patients experience an emergence reaction where they get confused and agitated as the ketamine is wearing off.\u201d\u00a0[13]<\/sup><\/p>\n\n\n\n

He adds that other adverse effects such as increased saliva production and decreased breathing \u201care very rare.\u201d<\/p>\n\n\n\n

Some people should avoid ketamine altogether.<\/p>\n\n\n\n

\u201cKetamine can trigger psychosis in patients who are at increased risk,\u201d Ross says. \u201cPeople with a strong family history of psychosis (such as schizophrenia) or serious mood disorders (such as bipolar disorder) might want to avoid ketamine.\u201d [13]<\/sup><\/p>\n\n\n\n

He adds that people with well-controlled schizophrenia or bipolar disorder should avoid ketamine as well. He notes, though, that \u201cketamine is frequently used to treat acute exacerbations of schizophrenia and bipolar disorder.\u201d [13]<\/sup><\/p>\n\n\n\n

Esmaeilpour says people considering ketamine also need to be informed about side effects. Common ones include dissociation, dizziness, nausea, and an increase in blood pressure. [12]<\/sup><\/p>\n\n\n\n

She adds that \u201cthe probability of psychological effects, such as hallucinations or altered perception\u201d is just as high as the other side effects.<\/p>\n\n\n\n

\u201cDepending on the dose and response of the individual, the side effects may be intense but very short-lived,\u201d says Esmaeilpour. Those with a history of substance abuse, as well as severe psychiatric disorders, may be predisposed to serious adverse events.<\/p>\n\n\n\n

She adds that \u201cindividuals with uncontrolled hypertension<\/a> or at risk of glaucoma may need to avoid ketamine because of its potential to worsen these conditions.\u201d [14, 15]<\/sup><\/p>\n\n\n\n

People who have any issues with their bladder or severe addiction issues should avoid ketamine, says Abigail Lev, PsyD, a San Francisco-based clinical psychologist who provides ketamine-assisted therapy with the Bay Area CBT Center<\/a>. [11, 16]<\/sup><\/p>\n\n\n\n

She stresses that the drug should be taken in moderation and with a physician\u2019s assistance, \u201cand be very careful because it can become addictive and should not be abused.\u201d<\/p>\n\n\n\n

FAQs<\/strong><\/h2>\n\n\n\n

What\u2019s the link between ketamine and sleep enhancements?<\/strong><\/h3>\n\n\n\n

\u201dUsing ketamine together with zolpidem may increase side effects such as dizziness, drowsiness, confusion, difficulty concentrating, excessive sedation, and respiratory depression,\u201d according to drugs.com. [17]<\/sup> \u201cSome people, especially the elderly, may also experience impairment in thinking, judgment, and motor coordination.\u201d<\/p>\n\n\n\n

The Cleveland Clinic also warns not to combine ketamine with other medications that can make you drowsy such as sleep medications, anti-anxiety medications, narcotic pain medications, or alcohol. [18]<\/sup><\/p>\n\n\n\n

Can ketamine be used to treat sleep disorders?<\/strong><\/h3>\n\n\n\n

Ketamine isn\u2019t typically used to treat sleep disorders, such as narcolepsy or sleep apnea. It’s used, however, to treat mental health disorders that commonly interfere with your ability to get a good night\u2019s sleep.<\/p>\n\n\n\n

Are there any side effects of using ketamine for sleep?<\/strong><\/h3>\n\n\n\n

It\u2019s important to understand that ketamine isn\u2019t a sleep aid, per se, but rather a drug used to treat depression and PTSD that can interfere with sleep.<\/p>\n\n\n\n
