Intake methods and effects

Ketamine has several different methods of intake. How ketamine is taken depends on the purpose—and dosage can vary accordingly. The characteristic effects are similar to the different methods of intake, but each has the potential to yield a unique experience, based on the individual, and other variables.

How does ketamine feel?

In general, ketamine can make a person feel dissociated from themselves or reality. This is sometimes considered a benefit, as it might provide the opportunity for more productive therapy sessions while processing difficult traumatic experiences (like in cases of post-traumatic stress disorder (PTSD).

Other possible effects can include a feeling of transcendence that allows a person to reflect more objectively on their lives, connect more deeply with themselves, or experience a sense of greater meaning. Ketamine might also intensify, enhance, or alter the appearance of colors, shapes, and sounds in one’s surroundings.

Ketamine can enhance a person’s feelings of dissociation. Dissociation can be unnerving for some people, particularly in cases of high dosage or a response that results in uncomfortable experiences involving hallucinations, anxiety, and psychosis. Dizziness can also occur, or the sensation of being stuck in one place.

For ketamine ingested orally (the clinical term for ketamine lozenges is a troche), users often report feeling numbness or tingling in their mouth and tongue. They also may report slight feelings of dizziness at the initial onset.

To minimize the likelihood of a negative response to ketamine, it should be taken under the guidance of a knowledgeable practitioner who can guide and supervise a ketamine experience.

How to Consume Ketamine:

 Here are the known intake methods and what can usually be expected in terms of effect.

 Drip or intravenous infusion

 It is common for ketamine to be administered at a clinic by way of infusion treatments, also called an IV (intravenous) drip. In this method, the medicine bypasses the digestive system and directly enters the bloodstream.

 For infusion treatments, a person typically receives ketamine in a limited series of sessions, with a period of supervision after each completed session which ensures patient safety. Even though the acute effects may fade within an hour or two, it can take the rest of the day (sometimes longer) to safely drive a car or operate machinery.

 Ketamine infusions occur as one part of a comprehensive therapy plan, which involves psychotherapy and (frequently) other psychiatric medications that may be needed.

 Injections or intramuscular shots

 An intramuscular injection of ketamine is a shot administered to the muscle tissue. The onset of effects can happen more quickly, and the treatment itself takes much less time than an infusion treatment (which can take about 40 minutes or longer). This might help increase the accessibility of ketamine to people for whom infusion treatments are not an option.

 Nasal inhaler

 Ketamine is available in a nasal spray or inhaler in both generic versions and in a version called Spravato. Spravato has been FDA-approved for the treatment of major depression when typical antidepressants have not been effective, and for acute treatment during the period of time it takes to see effects after first starting a medication.

 With Spravato, a person administers the medicine themselves under the supervision of a practitioner and stays in their care for a period of supervision. Operation of a vehicle or machinery, as well as other functions requiring uncompromised awareness of safety, should be avoided until the next day.

 Oral intake

 Ketamine is also available in the form of an oral lozenge called a troche, which takes the longest for the onset of effects. The lozenges are dissolved in the mouth and absorbed in the mucosa membranes of the mouth and tongue. The lozenge either remains under the tongue or when it is dissolved, a person “swishes” the dissolved lozenge in their mouth as it mixes with saliva. Then they swallow the solution after a period of time as directed by the prescriber (5-15 minutes).

 It can also be taken as an extended-release tablet, which research has found may help people avoid or minimize long periods of dissociation.

 These lozenges can be prescribed by a primary care physician, psychiatrist, or someone licensed to prescribe such as a psychiatric nurse practitioner. Taking ketamine orally may be less bioavailable than other methods, but can be a more affordable option. Depending on the severity of the patient’s symptoms, sometimes prescribers suggest lozenges in addition to an IV infusion, or injection treatments.

 Other Intake methods

 Ketamine comes in 2 forms: powder and colorless liquid. The other known methods of intake are by snorting the powder or ingesting the liquid orally (as is or mixed into a beverage), however, there is no documented use of these techniques in official trials related to therapy and are associated with personal or recreational use.

Usual Adult Dose for Anesthesia (ket@mine)

IV:

• Induction: 1 to 4.5 mg/kg IV; alternatively, 1 to 2 mg/kg IV at a rate of 0.5 mg/kg/min; (2 mg/kg dose provides 5 to 10 minutes of surgical anesthesia within 30 seconds)
• Maintenance: The maintenance dose should be adjusted according to the patient’s anesthetic needs and whether an additional anesthetic is employed. Increments of one-half to the full induction dose may be repeated as needed for maintenance of anesthesia.

IM:

• Induction: 6.5 to 13 mg/kg IM; (9 to 13 mg/kg IM provides 12 to 25 minutes of surgical anesthesia)
• Maintenance: The maintenance dose should be adjusted according to the patient’s anesthetic needs and whether an additional anesthetic is employed. Increments of one-half to the full induction dose may be repeated as needed for maintenance of anesthesia.

 Where can I get ketamine?

 Ketamine must be obtained and provided by a practitioner who has a license for use in therapeutic practice. Producing it at home or obtaining it other than from a practitioner is illegal.

Also, without the guidance of an experienced guide, a person who opts to use ketamine without direction from a licensed practitioner risks dangerous health complications, dependency, and possible addiction.

Ketamine is intended to be combined with other therapeutic modalities to achieve optimal success and long-term best outcomes.

 Safety and precautions

 Ketamine has been determined to be safe as a part of treatment for those with non-psychotic psychiatric needs for healthy adults. It should not be used by anyone with a history of or potential to develop psychosis. It is not intended for recreational or unsupervised use, can be dangerous if misused, and is not legal for those purposes.

 If ketamine seems like the right fit for addressing your mental health and personal therapeutic needs, it is important to locate a licensed and competent practitioner who can create an appropriate treatment plan for you.

 How to Take Ketamine Faqs:

 Are Ketamine Troches Addictive?

 Ketamine troches, like other forms of ketamine, have the potential for addiction and abuse. While they are prescribed for specific medical purposes under supervision, misuse or overuse can lead to addiction. Always follow your healthcare provider’s instructions and use ketamine only as prescribed.

 Can You Take Ketamine Troche on an Empty Stomach?

 It’s generally recommended to take ketamine troches on an empty stomach. This can help with absorption and reduce the likelihood of nausea, which is a common side effect. However, follow your healthcare provider’s specific instructions regarding dosing and food restrictions.

 How Is Ketamine Ingested?

Ketamine can be ingested in various ways. It is commonly administered intravenously (IV) in medical settings. Ketamine can also be taken orally in the form of pills, capsules, or troches (lozenges). Additionally, some people misuse ketamine by snorting or inhaling it, which is not safe and can lead to serious health risks.

 How to Take Sublingual Ketamine?

To take sublingual ketamine, place the ketamine troche under your tongue and allow it to dissolve completely. This method allows for quicker absorption through the mucous membranes under the tongue, leading to a faster onset of effects compared to oral ingestion.

 What Is the Best Way of Taking Ketamine?

The best way to take ketamine depends on your specific medical condition and the guidance of a healthcare professional. Ketamine should only be used as prescribed by a healthcare provider. The appropriate method of administration (intravenous, oral, or sublingual) will be determined based on your individual needs and the purpose of the treatment. Misusing ketamine for recreational purposes is not safe and can have serious health consequences.
