If you’ve tried medication after medication and still don’t feel like yourself, ketamine therapy may be the next step worth taking.

Colorado Mental Health Services offers IV ketamine infusion therapy for adults with treatment-resistant depression, PTSD, OCD, and other conditions that haven’t responded adequately to conventional treatment.

This isn’t a last resort. It’s an evidence-based, clinically supervised treatment that works differently from anything you’ve probably tried before.

What Is Ketamine Therapy?

Ketamine is a medication that has been used safely in medical settings for decades. At sub-anesthetic doses, it works on the brain in a fundamentally different way than traditional antidepressants, targeting the glutamate system rather than serotonin, and triggering rapid changes in neural communication in areas that depression, trauma, and chronic stress have effectively shut down.

Where antidepressants can take weeks to produce any effect, and often produce none at all, ketamine frequently produces meaningful symptom relief within hours to days of the first infusion.

At Colorado Mental Health Services, ketamine is administered intravenously, the delivery method with the strongest clinical evidence base, the most precise dosing control, and the most direct pathway to the brain.

Sessions are conducted in a calm, medically supervised environment with continuous monitoring throughout.

Conditions We Treat with Ketamine Therapy

Ketamine therapy at Colorado Mental Health Services is indicated for adults who have not achieved adequate relief from conventional treatments. Conditions we treat include:

Treatment-Resistant Depression 

For people who have tried two or more antidepressants without sufficient improvement, ketamine offers a clinically validated alternative. Its rapid mechanism of action makes it particularly relevant for people who have been managing depression for years without finding something that works.

PTSD and Complex Trauma 

Ketamine’s neuroplasticity-promoting effects make it a compelling option for PTSD and complex trauma — conditions where the brain’s threat-processing circuitry has become chronically dysregulated. Research supports its use in reducing PTSD symptom severity, particularly hyperarousal, avoidance, and intrusive symptoms.

OCD 

Emerging evidence supports ketamine’s effectiveness for OCD, particularly in cases where SSRIs and behavioral therapy haven’t produced adequate results. Its glutamate-targeting mechanism addresses a neurological pathway that standard OCD treatments don’t directly reach.

Anxiety Disorders 

For generalized anxiety disorder, social anxiety, and panic disorder that have not responded to conventional pharmacotherapy, ketamine’s rapid anxiolytic effects offer a meaningful clinical option.

Suicidal Ideation 

Ketamine has demonstrated rapid reduction in acute suicidal ideation — one of its most clinically significant and most underappreciated applications. For individuals in acute psychological distress, the speed of its effect is unlike anything else currently available.

How Ketamine Infusion Therapy Works

01

Before any infusion begins, you meet with our clinical team for a comprehensive evaluation. We review your psychiatric history, current medications, previous treatment trials, and overall health to confirm that IV ketamine is appropriate for you and to establish your individualized dosing protocol.  

02

You’ll receive detailed preparation instructions before your first infusion. Generally, this includes fasting for several hours beforehand, arranging transportation home (you cannot drive after a session), wearing comfortable clothing, and arriving without expectations about how the experience will feel.

03

You’re settled into a comfortable, low-stimulation environment. An IV line is placed, and the ketamine infusion begins, typically running 40 to 60 minutes at a carefully calibrated sub-anesthetic dose.

04

After the infusion, you rest in our facility for a brief observation period while the immediate effects wear off. Most people feel clear-headed within an hour, and a trusted person drives you home.

Insurance & Payment Options

IV ketamine infusion therapy is not currently covered by most insurance plans as a standard benefit, though this is evolving as the evidence base grows. Colorado Mental Health Services offers transparent pricing and flexible payment options to make ketamine therapy as accessible as possible.

We recommend contacting our team directly to discuss costs and payment arrangements before your consultation, so there are no surprises.

What To Know Before Your Ketamine Session

  • Do not eat or drink for at least 4–6 hours before your infusion (water is typically fine up to 2 hours prior — your clinical team will give you specific instructions). 
  • Arrange a driver you cannot drive yourself home under any circumstances.
  • Avoid alcohol and recreational substances for at least 24 hours before your session.
  • Disclose all medications to your provider before your first session — certain medications can interact with ketamine and may need to be adjusted.
  • Wear comfortable clothing — you’ll be reclining for 40–60 minutes.
  • Set your environment — plan for a calm, restful afternoon and evening after your infusion; this is not a day to schedule demanding obligations.
  • Come with openness, not expectations — ketamine experiences vary widely between individuals and even between sessions; approaching the experience with curiosity rather than a fixed idea of what should happen supports better outcomes.

Frequently Asked Questions

What is iv ketamine therapy and how is it different from other forms of ketamine?

 IV ketamine infusion delivers ketamine directly into the bloodstream through an intravenous line, allowing for precise dosing, rapid onset, and continuous monitoring throughout the session. It is the delivery method with the strongest clinical evidence base for psychiatric applications. Other forms — including Spravato (intranasal esketamine) and oral ketamine — exist but differ in bioavailability, dosing precision, and the clinical evidence supporting their use. IV infusion is considered the gold standard for treatment-resistant depression and related conditions.

Clinically administered ketamine is delivered at sub-anesthetic doses — approximately one-fifth the dose used for anesthesia — in a medically supervised environment with continuous vital sign monitoring. The dosing, setting, intention, and clinical oversight are fundamentally different from recreational use. The dissociative effects that occur recreationally at high doses are minimal or absent at therapeutic doses, and the entire experience is structured around clinical safety and therapeutic outcomes.

 Ketamine’s most significant clinical advantage over conventional antidepressants is its speed. Many patients notice meaningful symptom relief within 24 to 48 hours of their first infusion — sometimes sooner. This rapid onset is particularly significant for people experiencing severe depression or suicidal ideation, where waiting weeks for a medication to take effect is not clinically acceptable.

The standard initial protocol for mental health conditions is six infusions delivered over two to three weeks. This series approach produces more durable relief than a single session. Following the initial series, some clients achieve lasting remission; others benefit from periodic maintenance infusions. Your clinical team will work with you to determine the right ongoing approach based on your response.

Experiences vary significantly between individuals and between sessions. Common descriptions include a floating or weightless sensation, altered perception of time and space, mild visual changes, and a sense of emotional distance from habitual thought patterns. Some people find the experience profound; others describe it as unremarkable. Most people feel clear-headed within an hour of the infusion ending. You are monitored and supported throughout — you are never alone during a session.

During the infusion, temporary side effects may include dissociation, dizziness, nausea, elevated blood pressure, and blurred vision. These effects are short-lived and resolve as the infusion ends. Rarely, some people experience anxiety or emotional intensity during the session — your clinical team is present throughout and trained to provide support if needed. Longer-term risks with repeated use include potential effects on bladder function and cognitive processing, which is why ketamine therapy at Colorado Mental Health Services is delivered in a structured, clinically supervised protocol rather than open-ended administration.

Ketamine therapy is not appropriate for everyone. Contraindications include a personal or family history of psychosis or schizophrenia, uncontrolled hypertension, active substance use disorder (particularly dissociative or stimulant substances), certain cardiovascular conditions, and pregnancy. A thorough clinical assessment before your first infusion exists precisely to identify these factors — your safety is the first priority.

IV ketamine for psychiatric use is currently prescribed off-label — meaning it is not FDA-approved specifically for depression or PTSD, though it is FDA-approved as an anesthetic. Off-label prescribing is standard and legal medical practice when supported by clinical evidence, and the evidence base for ketamine in treatment-resistant depression is substantial — including endorsement from the American Psychiatric Association. Spravato (esketamine nasal spray), a ketamine derivative, does carry FDA approval specifically for treatment-resistant depression.

Most commercial insurance plans do not currently cover IV ketamine infusions as a standard benefit, though coverage is expanding as the evidence base grows. Spravato (esketamine) has broader insurance coverage due to its FDA approval. Colorado Mental Health Services offers transparent pricing and flexible payment options — contact our team to discuss costs before your consultation.
