It also has positive effects for people with chronic pain and fewer side effects than other pain medications. When administered by a practitioner in a controlled environment using a variety of techniques, it can help patients heal by processing, overcoming, and releasing trauma. As with any therapeutic process, an investment of time and money is often unavoidable. Ketamine is FDA-approved for chronic pain and anesthesia but prescribed off-label as a mental health treatment. Given ketamine’s status as a generic drug, insurance does not commonly cover its highly established, data-driven use as an off-label medicine.

You might mistake some of those intense sensations for an overdose. Knowing the signs and symptoms of an overdose is important, so you know when you or someone else needs help. Using ketamine or entering a K-hole does come with risks, some of them serious. The physical effects can be pretty unnerving to some people, too.

Is ketamine used as a medical treatment?

A form of ketamine known as esketamine nasal spray was approved by the FDA in 2019 under the name Spravato for use in treatment-resistant depression. A 2018 review has shown ketamine may also be effective for treating substance use disorders, such as alcohol, cocaine, or opioid use disorder. But its benefits, dosages, and safety for long-term use need further research. The best clinical evidence shows that patients should start treatment twice per week for 4 weeks.

1. This releases other neurons, excitatory or inhibitory, from their inhibition allowing them to spike vigorously and leading to ketamine’s excited brain state.
2. The effects of ketamine typically last minutes, depending on the dose.
3. The 2017 clinical trial tested the drug on 18 participants and concluded that it might effectively treat SAD.
4. Ketamine use can be fatal in people who are alcoholics or acutely intoxicated with alcohol.
5. Your doctor can tell you about the latest research and medical uses for ketamine, including the pros and cons of the drug.

Ketamine for Depression: What to Know

These approaches don’t always relieve severe depression symptoms, including thoughts of suicide — and that’s where ketamine could make a difference. Healthcare professionals first began using ketamine as an anesthetic in the 1960s. Before long, they noticed it didn’t just cause a sedative effect. A research after-work drinking team led by Dr. Conor Liston of Weill Cornell Medicine investigated how ketamine affects the brain after mice experience chronic stress. They used high-resolution imaging to focus on neurons in the prefrontal cortex. The study was funded in part by NIH’s National Institute of Mental Health (NIMH).

Ketamine treatment types

One recent study in the Journal of Clinical Psychology estimated that almost a third of the nearly 9 million people in the United States treated for depression each year have TRD. Given how common TRD may be, limitations in medication options — typically a crucial component of depression treatment plans — are a significant roadblock. Ketamine is also used as a recreational drug that can be abused for its dissociative sensations and hallucinogenic effects.

Given over 10 years of experience with ketamine as a researcher and physician, in this article I try to answer some basic questions prospective patients often have about ketamine/esketamine. A prescription version of ketamine called esketamine (Spravato), given through a psychological dependence on alcohol: physiological addiction symptoms nasal spray, was approved in 2019 by the FDA for hard-to-treat depression. Ketamine therapy is conducted in a controlled clinical environment with medical supervision. This ensures that people are monitored throughout, from medical consults to post-treatment follow-up.

What does a K-hole feel like?

Others describe it as being teleported to other places or having sensations of “melting” into their surroundings.

Off label refers to the use of a medication for something other than its approved uses. “Like all anesthetics, ketamine is not a good mixer,” alcoholic nose symptoms, causes, and treatment said Masand. There are sophisticated urine and blood tests that can detect ketamine, but a standard urine drug test probably won’t pick it up, Masand said. The main difference between different methods of ketamine administration is in the timing of the trip, said David Manjoubi, anesthesiologist and founder of Ketamine Healing Clinic of Los Angeles.

Ketamine and esketamine work differently from standard antidepressants. Selective serotonin reuptake inhibitors (SSRIs), for example, ease depression by increasing levels of serotonin, a chemical messenger carrying signals between brain cells. SSRIs block the reabsorption (reuptake) of serotonin, making it more available in the brain.

Healthcare professionals may use approved forms of ketamine as an anesthetic, as a sedative, or to treat depression. Healthcare professionals may currently also use ketamine “off label” to treat anxiety. As with any substance, getting ketamine on the street carries the risk that it’ll be cut with other substances.

The team found that the phasic inhibitory interneurons become stimulated by lots of input of the neurotransmitter glutamate from the excitatory neurons and vigorously spike, or fire. That stop signal, which reaches all the excitatory neurons simultaneously, only lasts so long, ends up synchronizing their activity, producing a coordinated gamma brain wave. The first prediction is that ketamine can disinhibit network activity by shutting down certain inhibitory interneurons. The modeling shows that natural blocking and unblocking kinetics of NMDA-receptors can let in a small current when neurons are not spiking. Many neurons in the network that are at the right level of excitation would rely on this current to spontaneously spike. But when ketamine impairs the kinetics of the NMDA receptors, it quenches that current, leaving these neurons suppressed.

She is the co-medical director of the ketamine clinic at Mayo Clinic. More research is needed to compare ketamine and esketamine directly. However, some research has suggested that the IV-infused drug provides a faster response than the nasal spray. Ketamine and esketamine, on the other hand, are thought to create more connections (synapses) between brain cells, a process thought to ease depression and decrease suicidal thoughts. Though they're far from perfect treatments, ketamine and esketamine mark a breakthrough for treatment-resistant depression.
