Ketamine-Assisted Therapy in Denver: What to Expect

Tue, 22 Sep 2026 15:54:53 GMT

Quick Answer: Ketamine-assisted therapy combines a low-dose ketamine treatment with psychotherapy. It's mainly used for adults whose depression hasn't improved enough with other treatments. At Confluence Psychiatry, you start with a free 10-minute call and a full evaluation with a psychiatrist , and you can choose to have a therapist in the room during treatment. Below is what happens before, during, and after a session, and what it costs.

If you've tried more than one antidepressant and you're still struggling, you've probably read about ketamine. Much of what's online either oversells it or makes it sound frightening. This guide explains what ketamine-assisted therapy at our Denver office actually involves.

What Is Ketamine-Assisted Therapy?

Ketamine has been used as an anesthetic for decades. At much lower doses, it has been studied as a treatment for depression, particularly depression that hasn't responded to standard medications.

Most antidepressants take weeks to work. Ketamine acts on a different brain chemical system, glutamate, and it's associated with a rapid response. Some people notice a change within hours or days. Individual responses vary, and it doesn't work for everyone.

Ketamine-assisted therapy pairs the treatment with psychotherapy. At Confluence, a therapist can be with you in person during the treatment. Ketamine can loosen stuck patterns of thinking for a short time, and a therapist helps you make use of that time.

Ketamine is FDA-approved as an anesthetic, and its use for depression is off-label.

Esketamine (Spravato), a related nasal spray, is FDA-approved for treatment-resistant depression. We offer both.

Who Is It For?

Ketamine is usually considered for adults with treatment-resistant depression , which means depression that hasn't improved enough after trying other treatments. It isn't a first-line option.

It may not be suitable if you have:

Uncontrolled high blood pressure or certain heart conditions
A history of psychosis
A current pregnancy
A history of substance misuse that hasn't been addressed

The evaluation is where we work through these questions. Dr. Charles Shuman is board-certified in addiction psychiatry, so questions about substance use history are reviewed by a specialist.

What Happens Before Your First Treatment?

A free 10-minute call. Speak with one of our physicians, ask your questions, and find out whether an evaluation makes sense. There's no obligation.

A comprehensive evaluation. You'll meet with a psychiatrist, a medical doctor with specialist training in psychiatry. We'll review:

Your symptoms and how long they've lasted
The medications and therapies you've already tried
Your medical history, current medications, and blood pressure
Any history of substance use

If ketamine is a good fit, the evaluation fee includes your first treatment. If it isn't, we'll say so and talk through other options, such as TMS , Spravato, or changes to your medication plan.

What Happens on Treatment Day?

Before you arrive

Arrange a ride home. You can't drive for the rest of the day.
Follow the eating instructions you're given ahead of your appointment.
Keep the rest of your day light.

During the treatment

We'll check your blood pressure and vital signs first. If you've chosen to have a therapist present, you'll spend a few minutes with them before starting.

Most people describe the experience as dreamy or detached. You may feel like you're floating, sounds and colors may seem different, and time can feel stretched. This is called dissociation. You stay awake throughout, and the effects fade soon after the treatment ends. You're monitored the whole time.

Afterward

You'll rest in the office until you feel clear-headed, then head home with your ride. Feeling tired or foggy for the rest of the day is common.

How Many Sessions Will I Need?

Ketamine is usually given as a series rather than a single session. Your psychiatrist will recommend a plan and check how you're responding along the way.

If it isn't helping, you won't be kept on it for the sake of it. Because TMS, Spravato, and medication management are all offered here, we can change course without sending you somewhere new.

What Are the Side Effects?

During or shortly after a session, some people experience:

Nausea or dizziness
A temporary rise in blood pressure and heart rate
Blurred vision or headache
Tiredness

These usually pass quickly. Ketamine can be misused, and frequent unsupervised use carries real risks, including dependence and bladder problems. That's why screening and medical supervision matter.

How Much Does Ketamine Therapy Cost in Denver?

Initial evaluation, including your first treatment: $360
Follow-up treatments: $250 each

Insurance doesn't cover ketamine treatment. We go over all fees with you before you schedule or pay for anything.

Book with one of our physicians. Ask your questions and find out whether an evaluation makes sense before you commit to anything.
