One of the most common questions we receive from patients considering IV ketamine for chronic pain is a simple one: how much will I receive, and what will it feel like? The answer is more nuanced than a single number — ketamine dosing for chronic pain is individualized, carefully titrated, and adjusted in real time based on each patient’s response. At Awakenings by Northwest Ohio Ketamine in Toledo, we believe that patients who understand what to expect from treatment are better prepared to engage with it meaningfully, and that preparation is part of what makes the difference in outcomes.
Why Ketamine Dosing Is Not One-Size-Fits-All
Ketamine is administered at different doses for different clinical purposes, and the dose used for chronic pain treatment is meaningfully distinct from both the anesthetic doses used in surgical settings and the recreational doses associated with misuse. Understanding those distinctions removes a significant source of confusion for patients approaching this treatment for the first time.
In anesthesia, ketamine is administered at high doses sufficient to produce unconsciousness and profound dissociation. In recreational misuse, ketamine is used at variable doses in uncontrolled settings with no medical oversight. In the context of chronic pain treatment, ketamine is administered at sub-anesthetic doses — doses substantially lower than those required for anesthesia — that produce therapeutic effects on the nervous system without rendering the patient unconscious. You will remain awake and able to communicate throughout the infusion. This is an important distinction from what many patients expect based on what they have heard about the drug.
The specific dose used at Awakenings for any individual patient is determined by our providers based on your medical history, weight, current medications, the nature of your pain condition, and your response during the infusion itself. Because IV ketamine is delivered intravenously, our team has continuous, precise control over the rate and amount delivered — adjustments can be made in real time if you are experiencing an effect that needs modifying. This is one of the reasons we use the IV route exclusively for ketamine therapy: it provides a level of control that other delivery methods cannot match. You can learn more about why IV is the preferred method for achieving this level of precision.
What Happens During an Infusion
Before your infusion begins, you will check in and our team will review any final questions about your history and current medications. You will be settled into a private, comfortable room — we recommend wearing loose-fitting clothing — and a small IV line will be placed. Your vital signs, including pulse, blood pressure, and oxygen levels, will be monitored continuously throughout the session. A call button is available if you need to communicate with staff at any point.
The ketamine is delivered slowly through the IV line over the course of the infusion. For chronic pain conditions, therapeutic ketamine infusions typically run longer than infusions used for mood disorders — this reflects the different dosing protocols appropriate to pain versus mental health applications, and our providers will discuss the specific parameters for your treatment during your consultation. Research supports the value of both single infusions and series of infusions for chronic pain, with repeated infusions generally producing more sustained relief.
During the infusion, most patients describe a state that ranges from mild relaxation and perceptual softening to more pronounced altered sensations depending on the dose. At sub-anesthetic doses appropriate for pain treatment, you may notice changes in how you perceive your surroundings, your sense of time, or the relationship between your body and the space around it. These effects are temporary and resolve as the infusion is completed and the medication clears your system. Some patients find these experiences unremarkable; others find them significant. Preparation — including setting clear intentions for the session, as our team will discuss with you beforehand — can help you approach the experience with a degree of equanimity regardless of how pronounced the effects are.
Zofran (ondansetron, an anti-nausea medication) is available to all patients and can be administered through the IV line if needed. For patients with a history of elevated blood pressure or heart rate, our providers may administer a small additional medication to keep those parameters in a safe range during the infusion. You will not be sedated — this is a monitored, medically supervised experience, not a procedure requiring unconsciousness.
The Role of Neuroplasticity in Pain Relief
Understanding why IV ketamine may produce relief that extends well beyond the duration of the infusion itself requires understanding its effect on neuroplasticity — the brain’s capacity to reorganize its neural connections. Research supports that ketamine promotes neuroplasticity, potentially strengthening connections between neurons or restoring connections that have been disrupted by chronic pain and the neurological changes that accompany it.
This is distinct from how most conventional pain medications work. Opioids, for example, bind to receptors in the pain pathway and produce relief while they are active in the system — when the medication clears, so does the pain relief. Ketamine’s effects on the glutamate system and NMDA receptors (N-methyl-D-aspartate receptors) trigger downstream changes in neural connectivity that can persist for weeks or months after a course of infusions. The infusion is the catalyst; the neuroplastic changes it promotes are what produce the longer-term relief. For a deeper look at this mechanism, our post on the science behind ketamine therapy and how it works in the brain explores this in detail.
This also explains why a series of infusions tends to produce more sustained benefit than a single infusion. Each infusion builds on the neuroplastic changes initiated by the previous one, progressively reinforcing the neural reorganization associated with pain reduction. Research on single, repeated, and maintenance ketamine infusions documents this cumulative effect — both single and repeated infusions are effective, with repeated infusions extending the duration of benefit.
What the Initial Course Looks Like
For chronic pain patients at Awakenings, we begin with a series of infusions — the specific number and frequency are determined based on your individual presentation and discussed during your consultation. Research supports the value of a structured initial course for establishing a durable therapeutic response rather than assessing efficacy after a single infusion, which may not represent the full potential benefit.
Following the initial course, patients are monitored for response and a maintenance plan is developed based on how long the benefits last and what level of ongoing treatment sustains adequate relief. Some patients go several months between maintenance infusions; others benefit from more frequent sessions. Results vary by individual, and we are transparent about that at every stage of the process. We do not guarantee outcomes — no ethical provider can — but we will give you an honest assessment of what the evidence supports and what the typical response pattern looks like in patients with your type of pain condition. Understanding how long chronic pain can last and how it evolves over time is an important part of that conversation.
Integration and Recovery After Each Session
Because ketamine temporarily affects coordination, perception, and reaction time, you will need a driver to take you home following each infusion. You should not drive or operate machinery for 24 hours after treatment. Most patients are ready to be discharged within 30 to 60 minutes following the end of the infusion as the immediate effects resolve, though this varies.
At Awakenings, we encourage patients to approach the period following an infusion as an opportunity for rest and reflection rather than immediate return to demanding activity. Recording thoughts or impressions from the session — either by speaking into a phone during the infusion or writing afterward — can be useful for the integration process: making sense of the experience and connecting any insights from the session to the practical goals of your treatment. Our team, including Ben Wagner, PMHNP-BC, our board-certified Psychiatric Mental Health Nurse Practitioner with seven years of clinical experience including ketamine-assisted therapy, is available to support this process. To understand the full scope of what to expect from start to finish, explore the Awakenings healing journey.
The day after an infusion, many patients feel tired. This is normal and reflects the neurological work the session has done. We recommend protecting sleep in the 24 to 48 hours following an infusion and avoiding alcohol during the treatment course, both of which can affect how well the neuroplastic changes from the infusion consolidate.
Two Barriers Worth Addressing Before You Decide
The most common concern patients raise beyond the treatment itself is cost. We do not accept insurance as a primary payer for IV ketamine infusions. Some insurance plans will cover all or a portion of treatment as an out-of-network service, and we will provide the documentation to support your claim if applicable. CareCredit financing is available to spread the cost over time. Active and former military with a valid ID or DD-214, and first responders with a badge, receive a 25 percent discount. We discuss the financial picture with every patient before any treatment decision is made.
Fear of the experience itself is also a real barrier. Patients who have heard about ketamine primarily in the context of recreational misuse or surgical anesthesia may approach the idea of an infusion with significant apprehension. The clinical context — sub-anesthetic doses, continuous medical monitoring, a private room, a call button, and a team that has guided many patients through this process — is categorically different from those other contexts. Our free initial consultation is an opportunity to ask every question you have about what the experience involves before committing to anything. You can also review our ketamine FAQs to get answers to the most common questions patients ask before starting treatment.
Frequently Asked Questions
Will I feel high during a ketamine infusion for chronic pain? At the sub-anesthetic doses used for chronic pain treatment, most patients experience mild to moderate perceptual changes rather than the intense dissociation associated with recreational use. The experience varies by individual and dose. Our providers adjust dosing in real time to optimize the therapeutic effect for your situation, and our staff is present throughout if you need support.
How long does each infusion take for chronic pain? Infusions for chronic pain conditions generally run longer than those used for mood disorders, reflecting the different dosing protocols appropriate to each application. Your provider will discuss the specific duration for your treatment during your consultation.
How long will the pain relief last after a course of infusions? Research shows that a series of infusions can produce relief lasting months for some patients, with maintenance infusions used to extend benefit over time. Results vary by individual — some patients find relief sustained for several months between sessions, while others benefit from more frequent maintenance treatment. We discuss realistic expectations based on your specific condition and history.
Can I continue my current pain medications during ketamine treatment? In most cases, yes. Most pain medications do not significantly interfere with IV ketamine’s mechanism of action. MAO inhibitors may need to be tapered before treatment, and our team reviews your full medication list during the consultation. We encourage you to discuss any medication changes with all providers currently involved in your care.
What if I have a bad experience during the infusion? Adverse experiences during ketamine infusions are uncommon at sub-anesthetic doses and with proper preparation, but they can occur. Our team is present and monitoring throughout, and a call button is available. If an infusion produces significant distress, our providers can adjust the rate or discontinue the infusion. Preparation beforehand — including intention setting and knowing what to expect — meaningfully reduces the likelihood of a difficult experience.
