What Is Ketamine?

Ketamine Infusions for Pain Management

Ketamine is an anesthetic drug which is approved by Food and Drug Administration (FDA). For many years, Ketamine has been used safely in operating rooms and Emergency departments. When given at lower and control doses than those used for anesthesia, Ketamine can:

  • Influence NMDA (N-methyl-D-aspartate) receptors involved in pain transmission.
  • Help calm or “reset” overactive pain pathways in the brain and spinal cord
  • Reduce central sensitization, which may lower overall pain intensity for some patients

In pain management, ketamine is typically used “off-label” (a medically accepted practice when supported by clinical judgment and available evidence) to help treat certain types of chronic, severe, or neuropathic pain.

Conditions Ketamine Infusions May Help

Ketamine infusions are not a first-line therapy.  They’re generally considered for those patients who’ve gone through traditional treatments like medications, Physical therapy, injections, or even surgery, but still struggle with persistent pain.

Conditions where ketamine infusions may be considered include:

In addition, ketamine has been studied for treatment-resistant depression, as Ketamine plays a significant role in managing pain. Hence, at Pain Treatment MD, we offer this as an option for chronic pain.  But in case mood or depression is a significant factor, we may collaborate with your mental health provider to coordinate care.

Conditions where ketamine infusions may be considered include:

Who Is a Candidate for Ketamine Infusions?

You may be a candidate for ketamine infusions if:

  • You have chronic, severe pain that significantly interferes with daily life and function.
  • You have tried appropriate, guideline-based therapies (medications, interventions, rehabilitation), but still struggle with severe pain.
  • You do not have other medical issues like uncontrolled cardiovascular disease, uncontrolled high blood pressure, active substance misuse, untreated psychosis, or certain other contraindications.
  • You are willing to participate in a structured treatment plan that may include medications, procedures, physical therapy, and behavioral strategies.

A thorough evaluation is required before ketamine can be recommended. This includes medical history, medication review, physical exam, and often input from your other providers.

How Ketamine Infusions Are Performed

How Ketamine Infusions Are Performed

Ketamine treatment works like a day-care procedure. You visit the clinic for your infusion, relax under supervision, and head home the very same day. In our clinic, the treatment is offered in a comfortable setting with proper monitoring.

Step 1: Consultation & Planning

In the initial step, we take a complete history to review your past treatments, imaging results, and overall health. We also discuss the potential benefits, limitations, and risks of ketamine infusion therapy. This step helps determine whether ketamine is the right option for you or if other treatments might be more suitable.

Step 2: Pre-Infusion Preparation

Before your infusion therapy, you might be asked to avoid certain foods or drinks for a short period, depending on your plan. We'll review your current medications and may adjust some in coordination with your prescribing doctors. We'll also take baseline vital signs, including blood pressure, heart rate, and oxygen levels, to ensure your safety.

Step 3: IV Placement and Dosing

A small IV line is placed, usually in your hand or arm. Ketamine is administered via controlled intravenous infusion over a set period of time (for example, 40–60 minutes for many protocols; the exact schedule is individualized). Dosing is carefully calculated based on your weight, medical conditions, and response.

Step 4: Monitoring During the Infusion

Throughout the infusion, your vital signs and comfort are monitored. You are typically in a reclined or semi-reclined position in a quiet environment. It is common to experience mild, temporary side effects such as a "floating" sensation, changes in perception, or feeling detached or dreamy. We closely monitor you and can adjust the infusion if needed.

Step 5: Recovery and Discharge

Once ketamine infusion therapy is done, we monitor you in the clinic for a period of observation until you are stable, oriented, and your vital signs are in normal range, as ketamine can temporarily affect alertness and coordination, so you will need a responsible adult to drive you home. We recommend that you not drive, operate heavy machinery, or make important decisions for the rest of the day. While leaving the clinic, you will receive written post-infusion instructions and a follow-up plan.

What to Expect After Ketamine Infusions

Immediate Effects

During or shortly after the infusion, some patients report a temporary reduction in pain or a change in how their pain feels. Some patients may feel tired, “foggy,” or emotionally sensitive after the infusion; these effects usually resolve over hours.

Short-Term Recovery (First 24 Hours)

You may feel fatigued or mildly off-balance; rest is recommended.  Avoid driving, alcohol, and sedative medications unless specifically cleared. Mild nausea or headache can occur in some patients and is usually manageable with supportive care.

Longer-Term Response

Ketamine’s effects on pain can vary. Some patients experience meaningful improvement in pain intensity and function for days to weeks after a series of infusions. Others may notice only a temporary benefit or little change.  In many protocols, ketamine is given as a series of infusions over a set period, followed by “booster” infusions only if benefit is demonstrated and maintained.

What to Expect After Ketamine Infusions

Short-Term Recovery (First 1–2 Weeks):

For smooth recovery, your healthcare provider may ask you to avoid strenuous activities for at least one to two weeks. We also generally recommend staying away from anti-inflammatory medications like ibuprofen or naproxen before and after your PRP session, as they can interfere with the healing process. If you need relief, ice or acetaminophen (Tylenol) can be prescribed.

Longer-Term Improvement:

PRP works by promoting healing, so it doesn’t offer instant numbing like steroid or anesthetic injections. Most patients start noticing improvement within 4–6 weeks, with continued progress over the next 3–6 months as the tissue repairs and strengthens. Some conditions may need more than one treatment, typically 1–3 PRP sessions spaced a few weeks apart, depending on how severe the issue is and how your body responds.

Potential Benefits

When carefully used in appropriate patients, ketamine infusions may:

  • Reduce severe, chronic, or neuropathic pain that has not responded to other treatments.
  • Improve function and quality of life in select patients. 
  • Help decrease reliance on certain pain medications in some cases.
  • Address central sensitization (over activity in the pain-processing pathways) in certain pain syndromes.

It is important to emphasize that results vary, and no outcome can be guaranteed. Ketamine is one tool within a comprehensive pain management program, not a stand-alone cure.

Potential Benefits

Risks and Side Effects

Ketamine infusions are generally well-tolerated when performed in a monitored medical setting. As all medical treatments carry some risks. Potential side effects and risks include:

Common or Short-Term

Changes in perception or sensation (feeling “floaty,” detached, or dreamy), Drowsiness or fatigue, Nausea or vomiting, Dizziness or imbalance, Temporary rise in blood pressure or heart rate, Mild anxiety or restlessness

Less Common or More Serious

More intense dissociative or hallucinatory experiences,

Significant elevation in blood pressure or heart rate, Allergic reaction (rare),

Breathing changes in susceptible individuals – Worsening mood or emergence reactions in some patients

Long-Term Considerations

Ketamine has potential for misuse when used inappropriately. At Pain Treatment MD, Ketamine is administered only in a controlled and monitored medical setting.  We never prescribe take-home ketamine for unsupervised use for pain. When administered repeatedly in high doses, Ketamine can cause bladder and urinary tract problems. That’s why our team follows proper medical protocols while administering Ketamine. We use lower, controlled dosing with monitoring to minimize risk. We will review your personal risk factors in detail and answer all of your questions before proceeding.

How Many Infusions Will I Need?

Protocols vary, but often include:

An initial “series” of infusions over days or weeks to assess response.  Reassessment after the series to determine whether ketamine provided a meaningful benefit. If helpful, periodic booster infusions may be considered, always weighed against risks, cost, and other available treatments.

Your plan will be individualized based on your condition, response, and overall treatment goals.

Preparing for Your Ketamine Infusion

Preparing for Your Ketamine Infusion

Our team will give you specific instructions, which may include:

Fasting guidelines (when to stop eating and drinking before the infusion, if applicable). Medication adjustments prior to the procedure (only with coordination from your prescribing doctors). Avoiding alcohol and recreational drugs before and after the

Infusion. Arranging for a responsible adult to accompany you and drive you home.

Medications (as appropriate and evidence-based) – Interventional procedures (injections, nerve blocks, neuromodulation, etc.) – Physical therapy and therapeutic exercise –

Lifestyle modifications and weight management when appropriate – Behavioral and psychological support for coping with chronic pain

Our goal is not only to reduce pain but also to improve function, independence, and quality of life.

Frequently Asked Questions

Most patients feel just a quick pinch when we draw their blood and a bit of pressure during the injection. Local anesthetics are being used to minimize discomfort. You may experience mild soreness afterwards, which you will manage easily.

For PRP, Insurance coverage can vary and is often limited. But you don’t need to worry about it. Our team is here to help you understand the costs and go over any insurance or self-pay options before your PRP appointment.

Plan for about 60–90 minutes.  This time period includes check-in, blood draw, PRP preparation, the injection itself, and a short observation period afterward.

Initial improvement is seen within a few weeks after PRP. But the full benefits of PRP usually develop gradually over a few months as your tissue heals.

Yes, it can! PRP often works even better when paired with treatments like physical therapy, exercise, weight management, and other pain-relief approaches.

PRP promotes long-term tissue repair by natural healing. In contrast, steroid injections provide prompt but short-term relief. Steroids don’t repair tissue and can’t be repeated frequently. PRP may be used when steroids are no longer effective or to limit steroid use.

This depends upon the symptoms and severity of your condition. Your overall health assessment also plays an important role in deciding the number of PRP sessions. Some patients feel good just with one injection, while others may require 2- 3 sessions spaced a few weeks apart. At our clinic, Dr. Jain creates a personalized plan based on your response to the first treatment.

If you’re dealing with joint, tendon, or chronic musculoskeletal pain and want to learn if PRP injections could help, we’re here for you.
