Earlier this year, the FDA approved a form of the drug ketamine to treat depression. Ketamine is a fast-acting antidepressant that relieves depressive symptoms in hours instead of the weeks or longer that previous drugs required. In addition to being a major advance in treatment, ketamine provides an opportunity for researchers to investigate the short- and long-term biological changes underlying its effects on depression. During the past 20 years, ketamine has been proven to be effective as an off-label treatment for a variety of mental health disorders, including depression, anxiety, PTSD, and suicidality. It has been shown to be particularly effective for people suffering from treatment-resistant mental health disorders—those patients who have tried many medications and treatments and still do not get well.
Ketamine for Addiction: What to Know
“It does have this tendency to cause aberrant behavior that can cause certain death,” he added. Fentanyl caused the most deaths – 2,541 – followed by cocaine (1,149) and methamphetamine (995). At fourteen days, 48 percent of participants in the ketamine group remained abstinent compared with 11 percent in the midazolam group. Craving scores were lower in the ketamine group, and, at the six-month follow-up, 44 percent of the ketamine group reported cocaine abstinence, whereas none in the midazolam group were abstinent. This means they’re made in a lab (distinct from morphine or heroin which come from the opium poppy). Nicole Lee works as a paid consultant to the alcohol and other drug sector.
How do I recognize an overdose?
Research from 2018 suggests ketamine may work by binding to the N-methyl-D-aspartate (NMDA) receptor in the brain to block glutamate. The World Health Organization (WHO) estimates that, when injected, lethal doses of ketamine begin around 11 mg/kg of body weight. This could be a dosage of about 680 mg for a person around 60 kg.

After overusing ketamine for an extended period of time, some experience ketamine cystitis—damage to the bladder that can lead to pain and frequent urination. If a person really overdoes it, they could experience psychosis that resembles schizophrenia, even after they stop using ketamine. At low doses, this can be a pleasant experience, making someone feel “at one with the universe,” said James Giordano, professor of neurology and biochemistry at Georgetown University Medical Center. Or, it might give them a more objective perspective on their lives, as it did with me. Aside from being a sedative, Ketamine has dissociative properties, which means it can make you feel disconnected from your body and the world. “This may be accompanied by vivid dream-like feelings and out-of-body experiences,” Masand said.
More on Depression
Response rates as high as 70% have been observed in clinical trials involving regular infusions. If you have certain health conditions, such as high blood pressure or heart-related problems, or certain mental health conditions, such as schizophrenia, ketamine may not be safe for you. Your doctor can tell you about the latest research and medical uses for ketamine, including the pros and cons of the drug. A lot of new research is currently being done on the various effects of ketamine. This includes benefits for mental health conditions such as treatment-resistant depression, PTSD, and suicidal ideation. A 2018 review has shown ketamine may also be effective for treating substance use disorders, such as alcohol, cocaine, or opioid use disorder.
As rates of depression and anxiety have increased dramatically, people have sought therapies outside the standard regimen of oral antidepressants and talk therapy. Beginning in the mid-2010s (see figure 1 in this paper), more doctors started offering ketamine as a treatment for depression. In 2019, the Food and Drug Administration (FDA) approved esketamine as a treatment for forms of depression that haven’t improved with standard antidepressants (like citalopram/Celexa or bupropion/Wellbutrin).
All three can be beneficial, though most of the clinical research proving ketamine’s effectiveness for mental health conditions has been conducted with IV infusions of ketamine without psychotherapy at the same time. There has been much written recently about ketamine and, more broadly, psychedelics and their use in treating mental health disorders. Ketamine is in a different bucket than other psychedelics such as MDMA and psilocybin because it has more than 50 years of clinical use, research, and significant patient safety and efficacy data behind it. “It may not matter, but it does concern me, personally, that ketamine works through an opioid mechanism,” he says.

- Hemodynamic instability Temporary increases in blood pressure, heart rate, and cardiac index may be observed during administration.
- Aside from being a sedative, Ketamine has dissociative properties, which means it can make you feel disconnected from your body and the world.
- It is referred to as a “dissociative anesthetic hallucinogen” because it makes people feel detached from their pain and surroundings.
Because experiences with ketamine vary so drastically, it’s hard to know what you’ll feel on it. That said, here’s what you should know if you’re thinking of trying it. Ketamine also causes individuals to have no memory of events that happen while they are under its influence.
While the drug is largely eliminated from the body within 14 to 18 hours after the last dose, it can also have longer-term effects. People who have used this drug report harsh flashbacks even weeks after the drug has been cleared https://sober-home.org/ from the body. This drug has been linked to conditions like depression, hysteria, memory loss, and high blood pressure in regular users. There’s one other actor in this play that’s important to mention, which is esketamine.
Further details of Matthew Perry’s death illustrate why this is so important. When friends and family who are depressed ask me if they should seek out ketamine as a potential option, I tell them that it doesn’t make sense unless they have tried oral antidepressants. The reasons for this are that ketamine/esketamine are riskier than standard antidepressants, require substantial commitments of time, and are more expensive. While ketamine overdoses are not strongly linked to death, consuming large amounts of this drug can be fatal. Discuss with parents and caregivers the benefits, risks, timing, and duration of surgery or procedures requiring anesthetic and sedation drugs. Millions of Americans are self medicating with alcohol, and others increasingly with marijuana, and so on, all the time.
The first is that ketamine is administered intravenously as opposed to routes like intramuscular injections, sublingually, or intranasally. The bioavailability of ketamine and the body’s absorption is 100 percent via the IV route, much greater than when delivered by any of the other methods. There are essentially three ways in which ketamine and psychotherapy can be used together for the benefit of the patient.
Evidence shows that ketamine is safe for use in people within a wide age range when taken correctly. Ketamine can produce hallucinations similarly to other drugs such as LSD and PCP, or angel dust. Ana Goñi-Lessan, state watchdog reporter for the USA TODAY Network – Florida, can be reached at Since fentanyl test strips were https://sober-home.org/high-functioning-alcoholic-how-to-identify-the/ decriminalized in 2023, Santamour said his harm reduction organization has passed out up to 25,000 test strips. Xylazine test strips have not been decriminalized in Florida, but fentanyl test strips are not considered paraphernalia as of 2023. Nationally, 27 states allow for the possession of all drug checking material.
Your breathing, blood pressure, oxygen levels, and other vital signs will be watched closely. Ketamine is injected into a muscle or a vein when used medically. Increase in cerebrospinal fluid pressure An increase in intracranial pressure has been reported following the administration of this medicine. Patients with elevated intracranial pressure should be in a monitored setting with frequent neurologic assessments. Risks of using ketamine alone for procedures of the pharynx, larynx, or bronchial tree Pharyngeal and laryngeal reflexes are not suppressed with ketamine when it is used alone. Avoid use as a sole anesthetic agent in surgery or diagnostic procedures of the pharynx, larynx, or bronchial tree.
Symptoms may not improve much or at all, or they may improve but keep coming back. The effects of ketamine typically last minutes, depending on the dose. For some people, the effects can last for several hours or even days, according to the National Institute on Drug Abuse (NIDA). However, research shows that people who tend to use recreational ketamine chronically are experiencing more depression symptoms than those who only use it occasionally. They may seek a way to escape their negative feelings, which the k-hope experience can provide via its dissociation effect.
It is important to distinguish between the valid medical uses and the nonmedical uses of the drug. Although people with certain heart conditions should not take ketamine, it is generally safe when a trained professional administers it in clinical settings. A 2016 study cautions that the inappropriate use of ketamine is a worldwide health problem due to its hallucinogenic properties. With this in mind, they urge doctors to prescribe standard antidepressants before trying ketamine for depression.
A ketamine overdose can occur when the substances is taken in large amounts or when combined with other substances. Coupled with its ability to produce an out-of-body experience, this drug can cause visual and auditory perceptual changes. In addition, the FDA now recognizes the antidepressant benefits of ketamine when it is combined with oral depressants.
Whether it’s being replaced with something else, however, is unknown. The drug is used to stretch out the effects of opioids, and, combined with fentanyl, it increases the risk of respiratory depression, which can lead to death. Among the drugs found in those who overdosed, ketamine (sometimes called ‘Special K’), xylazine (‘tranq’) and cathinones, also known as bath salts, were present in more people in 2023 than in 2022. Drug overdose deaths are still on the decline in Florida, but toxicologists, drug experts and those who advocate for people who use drugs say they don’t have a concrete answer for why.
