Ketamine Therapy for Chronic Pain: What You Need to Know

April 22, 2025

Ketamine and Spravato

Living with chronic pain can feel overwhelming. Every daily activity can become a challenge, and conventional treatments don’t always work. That’s where ketamine therapy, a cutting-edge approach, shines as a potential pain management breakthrough. 

Intriguing, right? This blog dives into how ketamine therapy—both intravenous and via esketamine (Spravato) nasal spray—offers hope for chronic pain sufferers. We’ll explore how it works, how long its effects last, and what you need to know if you’re considering it as a treatment option.

 

What Is Ketamine Therapy and How Does It Work? 

Ketamine has a history. Originally developed as an anesthetic, researchers later discovered its unique ability to alleviate chronic pain and even improve symptoms of mental health disorders like depression. Today, the medical community leverages ketamine at much lower, carefully monitored doses for therapeutic purposes. 

The Science Behind Ketamine’s Pain Relief 

Ketamine works by targeting NMDA (N-methyl-D-aspartate) receptors in the brain, which are part of the pain transmission system. By blocking these receptors, ketamine helps “reset” the nervous system, reducing the sensation of pain. Additionally, ketamine triggers the release of glutamate, a neurotransmitter that promotes healing and resilience by forming new neural pathways. 

For chronic pain sufferers, this means ketamine doesn’t just mask the pain—it influences the way the brain processes it at a fundamental level. 

Two Popular Forms of Ketamine Therapy for Chronic Pain 

  1. Intravenous Ketamine Infusion: The most common method, this involves low-dose ketamine administered intravenously at a clinic under medical supervision. 
  2. Esketamine Nasal Spray (Spravato): FDA-approved for treatment-resistant depression, esketamine has shown promise in managing associated neuropathic pain or other forms of chronic pain. 

 

The Benefits of Ketamine for Chronic Pain 

For those who have tried standard treatments with little relief, ketamine can offer several advantages. 

  • Rapid Pain Relief: Unlike some treatments that take weeks to show results, ketamine often provides relief within hours to a few days after administration. 
  • Improved Mood: Chronic pain often leads to mental health challenges such as anxiety or depression. Ketamine’s mood-enhancing effects can be especially beneficial in boosting emotional well-being. 
  • Breakthrough for Resistant Pain: Ketamine has been successful in cases where traditional painkillers and therapies have failed, making it a viable option for those with complex pain syndromes.

 

How Long Does Ketamine Pain Relief Last? 

One of the most common questions is how long ketamine’s benefits persist. Unfortunately, the answer isn’t one-size-fits-all and depends on factors including the nature and severity of your pain, the treatment type, and how your body responds. 

For many, an initial round of 3 to 6 intravenous infusions over several weeks provides relief lasting days, weeks, or even months. Follow-up or “booster” sessions may be needed to maintain long-term results. 

Those using esketamine (Spravato) may rely on more frequent dosing (commonly twice weekly) as recommended by their healthcare provider.

 

How Does Ketamine Treat Chronic Pain? 

By influencing the brain’s pain pathways directly, ketamine moves beyond the “band-aid” solutions offered by many traditional therapies. It doesn’t simply numb the pain temporarily; it recalibrates the nervous system to reduce pain signals and promote healing over time. 

This is particularly impactful for conditions like fibromyalgia, complex regional pain syndrome (CRPS), and neuropathic pain. These chronic pain types often involve conditions like central sensitization, where the brain becomes hyperactive at processing pain. Ketamine enables a “reset,” reducing this heightened sensitivity. 

How Safe Is Ketamine for Those with Chronic Pain? 

When administered by medical professionals in a controlled environment, ketamine is considered safe. Common side effects like mild dissociation, dizziness, or nausea are usually temporary and well-managed by experienced clinicians.

Who Could Benefit from Ketamine Therapy? 

Ketamine therapy is often most effective for individuals who haven’t found relief through conventional medications or therapies. This includes those dealing with conditions such as: 

  • Fibromyalgia 
  • Migraine headaches 
  • Neuropathic pain 
  • Complex regional pain syndrome (CRPS) 
  • Severe arthritis or joint pain 

If your chronic pain has persisted for months despite trying various treatments, ketamine therapy might be worth considering. 

 

What to Expect During Ketamine Therapy 

Feel reassured knowing that ketamine therapy is a carefully monitored, personalised experience. Whether you’re opting for IV infusions or Spravato nasal spray, here’s how the process typically works: 

1. Initial Consultation 

Your healthcare provider will assess whether ketamine therapy suits your needs. They’ll evaluate factors like your pain history, other medical conditions, and prior responses to treatments. 

2. Treatment Session 

During intravenous infusions, you’ll receive ketamine in a relaxed clinical setting while under the supervision of medical professionals. A typical session lasts around 40 minutes to an hour. 

For Spravato, you’ll administer the nasal spray in a medical office, under similar supervision. The effects will kick in within minutes, during which you’ll stay monitored for any reactions. 

3. Post-Session 

Most people feel relaxed or mildly drowsy after a session. You’ll need to arrange for transportation home, as driving post-treatment isn’t recommended. 

4. Ongoing Care 

Consistency is key. You might start with a series of treatments before transitioning to maintenance sessions, depending on your progress and your doctor’s advice. 

 

Considerations Before Starting Ketamine Therapy 

Although ketamine therapy is promising, it’s not a silver bullet. Chronic pain is complex, and combining ketamine with other therapies, like physical therapy or cognitive-behavioural therapy (CBT), often yields the best results. 

It’s also worth noting that not all insurance providers cover ketamine treatment. Investigate costs and potential reimbursement options beforehand.
