Some people feel better for a few days, while others stay better for weeks. To keep the effect going, follow-up treatments—like more ketamine infusions or nasal spray sessions. Ketamine is legally used in medicine but is also tightly controlled due to its potential for recreational use and dissociative effects. Ketamine’s effects are enhanced by propofol, midazolam, and naltrexone; reduced by lamotrigine, nimodipine, and clonidine; and benzodiazepines may blunt its antidepressant action. Scientists have studied ketamine for mental health since the early 2000s, and the results have been promising.
Is Ketamine Safe?
To add even more complexity to what is ketamine how it works and may help with severe depression the way ketamine may affect the brain, a 2020 study suggests it may also influence other neurotransmitters, such as serotonin, a chemical directly linked to mood regulation and inflammation. In addition to improving your neuroplasticity through glutamate production, other benefits of ketamine are currently being studied. Living with depression can mean your neuroplasticity — the flexibility of your brain to create new connections — decreases over time. The fewer neuron connections your brain makes, the more your functioning may become impaired.
The initial effects of ketamine on mouse behavior occurred independently of its effects on spine formation. While the drug affected behavior within three hours, formation of the new spines took 12 to 24 hours. Formation of spines in the mice correlated with their behavior two to seven days after treatment.
- The people who suffer from neurodivergence are more likely to have depression.
- In the last 25 years, clinicians have expanded ketamine administration to people with mental health conditions thanks to a proof-of-concept study showing its rapid antidepressant effects.
- It affects over 8% of adults and nearly 20% of those between ages 18 and 25.
- Experts emphasize the need to continue exploring its long-term safety and effectiveness.
When someone develops ketamine bladder syndrome, they get lesions on their bladder, the lining of their bladder wears away, and they need to urinate frequently. Abuse and misuse of the medication are part of the “black box” warning on esketamine. “We think that the number of synapses goes down because severe stress triggers reactions in the brain that eliminate these synaptic connections,” Krystal says. None of the doctors interviewed for this story were involved in Winograd’s or Coulter-Scott’s care.

Mounjaro and Mood
This effect set in just 1 hour after their first dose and lasted as long as 1 month after their last dose. Naloxone and naltrexone are opioid antagonists that reverse the effects of fentanyl. We found 67 studies that involved 2309 people with a range of chronic pain conditions, including nerve pain conditions (e.g. diabetic nerve pain, postshingles pain), fibromyalgia, and complex regional pain syndrome.
The FDA approved it as an anesthetic and has also approved a chemically related nasal spray (esketamine) for the treatment of depression. We’ve covered the major neurobiological aspects of how ketamine works, so we can now introduce some hypothetical psychological ways ketamine may also help with suffering. At certain doses, ketamine can result in a mystical or spiritual experience. One may experience oneness with the universe, or feel they are a part of something greater.
What are the limitations of the evidence?
What should you look for in a reputable and safe ketamine clinic? A ketamine infusion can cause a profound dissociation from reality. One wonders if ketamine would be better controlled in a hospital setting, where there are protocols for safety in case anything goes wrong. Independent, outpatient ketamine clinics are popping up all over the place. It is estimated that there are currently hundreds to thousands of these clinics — almost all of which were established in 2019 when ketamine was approved for treatment-resistant depression.
Clinical characteristics of the sample population
The cost of other types of ketamine therapy can vary, depending on where you live, what form and dose you take, and other factors. Again, oral ketamine tablets are the only form of ketamine you can take at home. Your prescribing clinician will likely recommend having a friend, partner, or other trusted person present when you take them, just in case you experience any uncomfortable side effects or a negative reaction. Future research may help determine whether repeated ketamine treatments have more of an effect than a single dose. Another major advantage lies in the fact that ketamine works very quickly, Eriksson says. With traditional antidepressants, it may take weeks before you notice improvement in your symptoms.
Ketamine could provide hope for people with serious depression
- The study was funded in part by NIH’s National Institute of Mental Health (NIMH).
- Dr. Brian Johns has a great Psychology Today post to help people decide whether a ketamine clinic offers a reasonable level of quality care.
- Stewart follows up with all of his patients throughout their series or if they stop ketamine therapy.
- In addition, ketamine can be helpful for pain, which many people experience during the late stages of terminal illness.
- But there have been growing concerns among some doctors as hundreds of ketamine clinics have opened across the U.S., charging hundreds of dollars, in some cases, for infusions, injections and oral forms of the drug.
Ketamine is a hallucinogen that was approved by the Food and Drug Administration as an anesthetic for surgery decades ago, but it’s also used illegally as a party drug. Ketamine, in all forms, works by crossing the blood-brain barrier and disrupting communication between nerve cells. SC ketamine is an infusion injected into the fatty layer beneath the skin.
Major Depressive Disorder is also listed in the SSA’s official list of medical conditions. It’s not a usual depression treatment and can create mood worse if misused. However, any medicine can indirectly disturb mood due to side effects, variations in weight/appetite, or adjusting to health changes. No, but in some people—particularly if they take too much or stop abruptly—it can.

Like ketamine, esketamine can make you feel dissociated, dizzy, and nauseated. These side effects tend to peak within two hours, but to be safe, you must have a prearranged ride home and are not allowed to drive yourself away from your treatment center. Patients may start to feel the positive effects of esketamine treatment for severe depression within hours after treatment.
Ketamine has been shown to quickly stimulate glutamine signaling and restock glutamate receptors, allowing the brain to form new synapses. The boost in glutamine signaling results in a release of many neural growth factors. These molecules, called neurotrophic factors, stimulate the growth of new connections, including new synapses. This is the action thought to be behind the reason that ketamine is so effective for depression. Early research suggests IM ketamine may help with severe depression, bipolar disorder, and pain.
It’s as if those glutamate receptors – the catcher’s mitts – get so worn out or weak that they can’t grasp the glutamate anymore. The antidepressant effects wear off in hours, days, or a couple of weeks in people who only get a single infusion. For treating other conditions – such as anxiety, pain, PTSD, or bipolar disorder– there are differences in doses, number of treatments, and length of time between treatments. At his clinic, Stewart sees patients who have been diagnosed by other health care providers with a treatable condition. “Treatment protocols are based on the patient’s specific diagnosis and research,” Stewart says. The esketamine nasal spray has a “black box” warning about the risk of sedation and trouble with attention, judgment, and thinking, as well as risk for abuse or misuse of the drug and suicidal thoughts and behaviors.
