Millions worldwide suffer from anxiety disorders, including generalized anxiety disorder (GAD), social anxiety disorder (SAD), and panic disorders. If you’re among them, you may wonder: How Fast Does Ketamine Work for Anxiety? Anxiety disorders are the most common mental illnesses globally, significantly impacting daily life, relationships, and overall well-being.
Most of the people are actually accepting orthodox treatments-SSRIs, benzodiazepines, and therapy. For the most part, these have slow action or failure. That is not so with ketamine.Ketamine was not used as an anesthetic drug for the treatment purpose. It has found a recent role as a novel breakthrough in dealing with depression and anxiety. It functions differently from drugs; it acts quickly and most of the patients report relief within hours or days.
In this article, we’ll explore how quickly ketamine works for anxiety, what affects its speed, and what to expect from treatment.
What is Ketamine for the Treatment of Anxiety?
What is Ketamine?
Ketamine is a dissociative anesthetic. It was used in practice for several decades. In 1960, it was certified as anesthetic medication in recent years. However, experts found out it has remarkable reuptake-resistant antidepressant as well as strong anti-anxiety properties.
How Do Ketamines Work in the Brain?
Unlike most other drugs, ketamine is known to be a kind of an antidepressant with mechanisms of its action being notably different from typical other antidepressants. The main mechanisms of how ketamine effects work are suggested to be inter alia determined through the mechanism of interference through blockade of the NMDA receptors with levels of glutamate, which play a great role in brain plasticity. Stimulating effects towards production of such neurotransmitter raise connections of tissues in the neuron as well as improve mood. Anxiety symptoms ease up.
Ketamines for Anxiety vs. Depression
While ketamine was found to be used for depression, these studies showed that it can be applied for anxiety conditions, mainly on patients who do not show proper response to treatment in anxiety. Since most of those who did not respond to SSRIs or therapy are insistent on using ketamine, the fast response is a guarantee on most people.
How Soon Is Ketamine with Anxiety Treatment?
Another excellent thing about this ketamine treatment is how fast it is. Traditionally, an anti-anxiety pill usually takes some weeks for it to start working while in general ketamine works with a few hours or even days.
Timeline of Effects
- 0–1 hour: Some will be able to experience a feeling of relaxation as well as some form of a dissociation feeling.
- 1–24 hours: There can be some immediate alleviation of the anxiety by way of tension and worry dissipating.
- 24–72 hours: The greatest anti-anxiety effects are seen during this time frame.
- 1–2 weeks: Effects often plateau; dosing needs to be maintained.
Most patients will note a feeling of lightness, calmness, or clarity within the first 24 hours, and that is why ketamine is regarded as one of the fastest treatments for anxiety in existence.
Variables in Determining the Time of Onset of Action for Ketamine
There are several factors that determine how long ketamine is going to take a patient.
-
Dosage and Dosing Form:
Intravenous: The most frequent and most common route through which effects are to be expected the soonest (minutes to an hour) to be observed among most patients.
Intramuscular Injections :Quite as quick but relatively speedy .
Nasal Sprays: FDA approvals for treatment depression in which their effect has emerged within hours up to one day.
Oral Ketamine: This takes the longest time before administration because they have to wait for it to be metabolized before it becomes absorbed into the brain.
-
Patient Reaction toward Ketamine:
Genetic and metabolism ability, this also defines how soon the ketamine will be broken down.
Time of reaction likely to differ in each and every individual. Brain chemicals in all human beings are different.
-
The worst case of diagnosis for Anxiety disorder:
The patients with GAD will start to get better over the course of time.
Those with PTSD or SAD should show some level of improvement after a few visits.
-
Combination with Other Therapy:
- The infusion of ketamine is most potent when combined with other therapy such as Cognitive Behavioral Therapy, CBT, and lifestyle changes.
- Time response to change in those who are receiving other drugs.
What to Expect the Next Couple of Days Following a Ketamine Infusion?
Immediate Effects:
- Mild dissociative or “out-of-body”
- Euphoria, relaxation, and a feeling of serenity
- Drowsy or dizzy

- Anxiety reduces
- Clear and balanced in mental acuity
- Some patients report minor side effects of drowsiness
Long-Term Outcomes (Within the Last One Week):
- All patients, primarily reported reduced intrusive thoughts and therefore minimized in anxiety response
- Ketamine-induced effect is primarily observed between days to weeks. There shall certainly be the requirement of at least one follow up treatment session.
Studies and Clinical trials with ketamine in anxiety
Many studies that reveal fast onset of ketamine for anxiety disorders .
- The symptoms of generalized anxiety disorder were partially improved to almost complete resolution by 24 hours, as reported by a 2017 clinical trial.
- A 2020 clinical study showed that the treatment-resistant social anxiety disorder has also been treated using instant relief offered by Ketamine.
- A study reveals the result of long term anxiety relief resulting from low doses of infusions of this drug given at time intervals.
How Long Do the Effects of Ketamine Last?
Effects for a Few Hours:
The pain relief usually lasts between 3 days to 2 weeks following a single treatment.
Long-term Maintenance:
- Months are needed to be maintained on injections to maintain the relief of pain.
- With lifestyle modification, the relief is prolonged with ketamine treatment.
Side Effects and Risks Of The Therapy
Although it is safe for ingestion, there are some side effects that are present with ketamine:
Common Adverse Reactions:
- Dizziness
- Nausea
- Tachycardia
- Dissociation (minimum hallucination)
Long-Term Risks:
- It may cause tolerance if it is abused
- The long-term cognitive impairment effect of it is still unknown
- It should not be given to a confirmed substance abuser
Who May Benefit from Ketamine Administration?
Conditions in which ketamine may be used include:

Psychotherapy: CBT, exposure therapy, mindfulness therapy
Other emerging treatments: TMS, psychedelic assisted therapy (MDMA, psilocybin)
Cost and Access to Ketamine Treatment
Cost: $300-$800 per intravenous infusion, doses repeated
Insurance: Some insurance pays for esketamine (Spravato) that is only administered sporadically; IV ketamine is typically pay-out-of-pocket
Access: Increasing numbers of clinics are providing ketamine treatment, though still relatively decentralized and heavily regulated.
