Question 1

- question: "What happens during a typical ketamine therapy session?

Accepted Answer

A typical in-clinic IV session begins with a vital signs check, followed by IV catheter placement and the start of the infusion over 40 to 60 minutes. For a detailed walkthrough, see our guide on [what to expect from ketamine treatment](/guides/what-to-expect-ketamine-treatment/). You will usually be in a comfortable recliner or bed with an eye mask and headphones playing calming music. Effects begin within five to ten minutes and include altered perception, a sense of floating or detachment, and possibly visual imagery. A clinician monitors your vital signs throughout. After the infusion ends, you rest for 30 to 60 minutes until you feel stable enough to leave with your arranged transportation. For at-home sublingual sessions, you place the troche under your tongue, recline in a quiet space, and experience effects for 60 to 90 minutes.

Question 2

How many sessions will I need?

Accepted Answer

The standard initial protocol for IV ketamine is six infusions over two to three weeks. For sublingual at-home programs, the initial phase typically involves one to three sessions per week for four to six weeks. After the initial series, most patients transition to maintenance sessions — the frequency varies widely and is determined by how long your benefits last. Some patients maintain well with monthly sessions, while others need treatment every two to three weeks. Your provider will work with you to find the optimal maintenance schedule.

Question 3

What does dissociation feel like during ketamine therapy?

Accepted Answer

Dissociation during ketamine therapy is often described as a dreamlike state where you feel detached from your body and surroundings. Common experiences include feeling as though you are floating, a sense that time is moving differently, altered perception of sounds and space, and sometimes vivid mental imagery or colors with eyes closed. You remain aware that you are in a treatment session and can communicate if needed. Most patients describe the experience as unusual rather than frightening, especially with proper preparation. The intensity varies with dose and individual sensitivity, and your provider can adjust dosing to keep the experience within a comfortable range.

Question 4

Will I be unconscious or lose control during treatment?

Accepted Answer

No. Therapeutic ketamine doses are sub-anesthetic, meaning they are well below the doses used for surgical anesthesia. You will not lose consciousness, and you will maintain the ability to communicate with your provider if needed. While your perception and thought processes will be altered — sometimes significantly — you retain a fundamental awareness of who you are and what is happening. Patients occasionally feel a momentary concern about losing control, but this is a psychological response to an unfamiliar state, not an actual loss of control.

Question 5

How soon will I know if ketamine therapy is working?

Accepted Answer

Some patients notice improvement within hours of their first session — reduced depressive thoughts, improved mood, or a sense of emotional relief. Others do not notice meaningful changes until after the third, fourth, or even sixth session. The initial series is designed to build cumulative benefit, so it is important to complete the full course before concluding that treatment is not working. If you have completed six IV sessions or four to six weeks of sublingual treatment without any noticeable improvement, discuss next steps with your provider. Approximately 60 to 70 percent of patients with treatment-resistant depression respond to ketamine therapy.

Question 6

What should I do between ketamine sessions?

Accepted Answer

Between sessions, focus on activities that support your mental health and help integrate any insights from your treatment. Many patients find journaling, gentle exercise, adequate sleep, mindfulness practices, and continued psychotherapy especially helpful during the treatment series. The 24 to 72 hours after a session represent a window of enhanced neuroplasticity, making this an optimal time for therapy sessions if you are working with a therapist. See our [integration practices guide](/guides/ketamine-integration-practices/) for detailed strategies. Avoid alcohol and recreational substances, maintain your prescribed medication regimen, and follow your provider's specific guidance for between-session care.

Question 7

Can I eat or drink before a ketamine session?

Accepted Answer

Most providers recommend fasting for four to six hours before your session to reduce the risk of nausea, which is one of the most common side effects of ketamine. Clear liquids such as water are usually permitted up to two hours before treatment. Avoid heavy, fatty, or acidic foods on treatment day even outside the fasting window. If you take daily medications in the morning, ask your provider whether to take them as usual or wait until after your session. Following fasting guidelines significantly reduces the likelihood of nausea and vomiting during treatment.

Question 8

What if I have a difficult or frightening experience during a session?

Accepted Answer

Challenging experiences do occur, though they are less common than neutral or positive ones. If you feel frightened, anxious, or overwhelmed during a session, remember that the effects are temporary and will subside. You can communicate with your clinical team at any time — they can provide verbal reassurance, adjust lighting or music, or in rare cases, administer medication to ease anxiety. Many therapists note that difficult sessions sometimes precede meaningful therapeutic breakthroughs. After a challenging session, discuss the experience with your provider so they can adjust your dose or approach for future sessions.
