If a patient experiences substantial improvement (generally around 50% improvement in symptoms), the treatment pattern would shift to once per week for another four weeks. To sustain improvement, it’s often helpful to then shift to a maintenance schedule. At the Interventional Psychiatry Service at Yale, where I work, we often find that a pattern of one treatment every 3-4 weeks is sufficient for helping patients maintain the treatment’s antidepressant effects. If patients have consistent and substantial improvement in symptoms for at least 4-6 months, they may opt to then stop ketamine/esketamine after a discussion with their provider.
Medical use dosage forms
(Insurance may cover the cost of the psychotherapy sessions, however. Ask about your specific benefits.) “The cost of treatment is not an insignificant amount of money,” says De La Hoz. One issue is that because of the cost, it may only be available to those with higher incomes. “We have hope that this will become more accessible to all who need it, not just specific populations,” he says.
How the treatments are being used for mental health.
It pertains to the use of psychedelic drugs as a potential treatment for psychiatric or substance use disorders. One pain point is the need for more standardized clinical studies on these substances, and the guidance advises on study design through drug development of psychedelic medicines. (This is currently in draft form, and the public has a chance to comment before the final version is released.) In other words, the field of psychedelic therapy — both in research and legislation — is rapidly evolving. 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.
How ketamine relieves symptoms of depression
Treatment with ketamine rapidly relieved the abnormal behaviors in the stressed mice. The drug also quickly restored the coordinated activity of prefrontal neural circuits that were disrupted by chronic stress. However, the researchers found that ketamine didn’t work by halting the stress-induced spine loss. Studies in animals have shown that chronic stress also leads to the loss of communication between brain cells (neurons) in the prefrontal cortex area of the brain. The neurons lose dendritic spines, the small outgrowths on brain cells that receive signals from neighboring neurons. The effects of the drug can vary depending on the dose and form, as well as whether you’re using it illegally.
But there are serious risks linked to ketamine’s use, which is why it should only be given under the supervision of a doctor. The most serious are unconsciousness, high blood pressure, and dangerously slowed breathing. The drug could also cause long-term problems, such as ulcers and pain in the bladder; kidney problems; stomach pain; depression; and poor memory.
May Be Useful in Anxiety Disorders
These are not always easy things to sit with, let alone long enough to deal with. The first reports of using ketamine in psychiatric treatment came in 1973.

In addition, never use ketamine if you have been drinking alcohol, as this combination can be fatal, per StatPearls.
In addition, if you have depression, anxiety, or PTSD and are interested in ketamine therapy, talk to your primary care doctor and mental health provider about it, in conjunction with your usual medications for mental health. It also may be indicated for patients acutely experiencing major depression with suicidal ideation. One of the most impactful ways ketamine can be used for major depressive disorder is to decrease symptoms within 24 hours, according to the authors of the Psychopharmacology meta-analysis. https://sober-home.org/ This may be impactful for people who have treatment-resistant depression and who haven’t found relief with conventional treatment, such as antidepressants or psychotherapy. This doesn’t mean that depression is “cured” in a day, but it may help to rapidly lift the fog so patients can be aided by their current treatment regimens. Moving forward, other drugs could join ketamine in the realm of legal psychedelic medicine, as the FDA released draft guidance in June 2023 for clinical researchers in the field.
In one study, a participant described his experience with KAP as an “amplification” of his regular talk therapy. Combining ketamine with psychotherapy is ideal for someone already in a therapeutic relationship and motivated to further their understanding of themselves and their difficulties. Due to some of these side effects, it’s best to avoid driving or operating heavy machinery until the day after treatment. Keep in mind that these side effects are more likely with higher doses of ketamine.
But there are not compelling data to conclude that one is superior to the other or to predict who would benefit from one versus the other,” Krystal says. Of course, any comparison to opioids raises the question of the risk of addiction. Abuse and misuse of the medication are part of the “black box” warning on esketamine.
Another form of ketamine called esketamine was found to be even more potent, providing antidepressant properties at a lower dosage. In 2019, Spravato (a form of esketamine delivered intranasally) was approved by the FDA as an adjuvant treatment for treatment-resistant depression in adults. In 2020 it was approved for the treatment of major depressive disorder (MDD) with acute suicidal ideation or behavior in adults. With more than one in five Americans living with mental health conditions, the demand for new treatments has grown. However, much of the focus still remains on talk therapy and medication as the primary options. This is significant because it’s estimated that over 50 percent of people prescribed an antidepressant don’t respond to the first medication they try.
- With these walls down, patients can access these things in a controlled environment without fighting against the mind’s natural defenses.
- While these effects were also reported by users of street ketamine, because of ketamine’s use as an illegal substance, they were dismissed.
- The drug is delivered by nasal spray and is designed to be administered alongside a traditional antidepressant.
- For psychiatrist Alan Shatzberg, MD, who did some of the research that uncovered this, that’s concerning.
- The nasal spray Spravato can cost from $590 to $885 per treatment session.
- As a general rule, at least 4 weeks of treatment are required before it can be known if an antidepressant is helpful.
The scientific term for this stressed-out state, Robison says, citing animal research, is lateral habenula burst activity. Ketamine was shown to suppress this activity in depressed rats and mice, thereby turning on reward centers linked to mood. “Ketamine [may] hit a reset button in the brain and help people feel quite a bit better rather quickly — even though https://sober-home.org/alcohol-detox-and-rehab-programs-what-to-expect/ a single dose doesn’t last forever,” he adds. More research is needed to better elucidate the mechanisms of how ketamine may work in humans. As Dr. Robison explains, this process is believed to allow neurons to form new connections and fire together in ways that create novel pathways in the brain (called brain plasticity or neuroplasticity, per StatPearls).
Recreational ketamine may be used alone or mixed with other illegal substances. Because of this, it’s unclear if ketamine alone or a combination of other factors contributed to cognitive and behavioral side effects in studies. Some studies suggest the drug may have other medical uses, but more research is necessary to prove its safety and effectiveness in these areas. The Controlled Substance Act classifies ketamine as a Schedule III non-narcotic drug. Because of its pain-relieving and mental effects, it can cause dependence, the need to take higher doses to get the same effect, and addiction.
It’s important to note that there is increased risk of lower urinary tract symptoms with esketamine. Cases of cognitive impairment have occurred with high doses of ketamine, yet these were not seen in the clinical trials at typical doses. “We believe that the combination of medication and therapy is better,” says Robison. He describes ketamine as a bridge that can help take someone out of crisis so that they can successfully engage in therapy. In therapy, you can then talk to a mental health professional about your experience and what you learned. In addition, ketamine therapy may also help turn off a stressed-out state that the brain can get stuck in.
If you have treatment-resistant depression, then this treatment might break through that resistance. This approach may be used eventually to predict who is most likely to respond to ketamine therapy, researchers say. However, only 65% of patients treated with ketamine respond to therapy and a new Yale-led study published April 17 in the journal eLife helps explain why.
However, things are changing and there may be promising news in the future regarding insurance coverage. If the FDA approves ketamine for other conditions based on new research, your insurance plan could cover ketamine in the future for treatment-resistant depression and other conditions. But there is still much to learn about how ketamine works, which dosages are effective, and how safe it is. The DEA says higher doses of recreational ketamine can cause serious reactions. It is classified as a Schedule III non-narcotic substance in the United States and is illegal without a prescription. Ketamine is a general anesthetic that doctors find useful in emergency room settings when performing procedures, such as reducing fractures and treating joint dislocations.
Studies have looked into ketamine’s effect on depressed people who have a family history of alcoholism. “Soldiers, for them, it’s natural to consider themselves like a strong man,” Matrenitsky said, explaining that the effects of the ketamine therapy allow individuals to overcome defensive barriers over their emotions. Ketamine, a dissociative drug with hallucinogenic properties, was originally approved in the US and Ukraine for anesthetic use. When considering ketamine therapy, it’s important to consider the benefits and risks.
