What to Expect During a Ketamine Therapy Session

Ketamine therapy is a medically supervised treatment that uses low, controlled doses of ketamine – administered by IV infusion or intramuscular injection – to help relieve symptoms of treatment-resistant depression, anxiety, PTSD, and certain chronic pain conditions. Because it can work faster than traditional antidepressants, it has become an increasingly popular option in the mental health field. In this article, we’ll walk through what actually happens before, during, and after a ketamine session.

How Long Do Ketamine Sessions Last?

The length of a ketamine session depends on the method of delivery and the condition being treated. IV infusions typically run about 40 minutes to an hour, with additional time before and after for monitoring. Intramuscular injections tend to take effect faster and may involve a shorter active dosing period. However, patients are still observed for roughly an hour afterward. A full appointment, including check-in, monitoring, and recovery time, often lasts one to two hours.

What Happens During a Ketamine Therapy Session?

Before your session, a clinician will review your vital signs, medical history, and any medications you’re taking to confirm that ketamine is appropriate for you that day.

You’ll be seated or reclined in a comfortable, quiet room. A nurse or provider will place a monitor on your finger or arm to track your heart rate and blood pressure throughout the session, since ketamine can cause temporary changes in both.

Once the infusion or injection is administered, you may begin to feel effects within minutes.Many people describe a dissociative sensation – a sense of floating, detachment from the body, or altered perception of time and surroundings. Mild dizziness, nausea, or a dreamlike state are also common. These effects are expected and are closely monitored by clinical staff throughout the appointment.

You remain under direct supervision for the full duration of the dosing period and during the recovery window afterward, until the effects have substantially worn off.

How Many Ketamine
Sessions Are Needed?

Ketamine therapy is usually delivered as a series of sessions rather than a single treatment. A common starting protocol involves six sessions over two to three weeks. Some patients notice improvement in mood within hours or days of the first few sessions, which is faster than typical antidepressants.

After the initial series, many providers recommend periodic maintenance sessions – spaced weeks or months apart – to sustain the benefits, based on how each patient responds.

What Happens After My Ketamine Treatment Session?

Because ketamine temporarily affects coordination, judgment, and alertness, patients are not permitted to drive themselves home. You’ll need to arrange for someone to pick you up, or use a rideshare or taxi service.

Most clinics ask patients to avoid making major decisions, operating machinery, or drinking alcohol for the rest of the day. It’s also generally recommended to continue any other prescribed medications as directed by your provider, unless told otherwise, and to avoid eating a heavy meal shortly before your appointment.
