What chronic pain and psychiatric diagnosis is ketamine IV infusion therapy effective for?

Thrive IV provides physician-administered ketamine infusion therapy for chronic nerve pain at our Dartmouth, Massachusetts clinic — including neuropathic pain, neuralgia, complex regional pain syndrome (CRPS/RSD), and fibromyalgia. Unlike acute pain, chronic nerve pain persists and is notoriously hard to treat. Ketamine acts on pain-perception pathways in the brain, and Dr. Michael Pellegrino, DO — an emergency-trained physician who has administered ketamine many hundreds of times — tailors the protocol to each patient. Pain conditions call for longer infusions (two-hour or four-hour) than mood treatments, and are scheduled in extended time blocks for the best benefit.

The doctor uses ketamine IV infusion therapy to effectively reduce chronic pain including:
  • Neuropathic pain such as neuralgia and CRPS/RSD
  • Cancer pain syndromes
  • Phantom limb pain
  • Fibromyalgia
  • Central pain syndromes related to stroke, trauma or spinal injury
  • Chronic migraine headaches
  • Lyme pain
  • Chronic pelvic pain
  • Multiple sclerosis pain

Chronic pain differs from another type of pain called acute pain. Acute pain happens when you get hurt, such as experiencing a simple cut to your skin or a broken bone. It doesn’t last long, and it goes away after your body heals from whatever caused the pain. In contrast, chronic pain continues long after you recover from an injury or illness. Sometimes it even happens for no obvious reason. As many as 25% of adults in the US experience some form of chronic pain. If left untreated, it can result in depression and severe disability.

But there is help!

Ketamine therapy has been shown to help as many as 70-80% or more in some studies. We specialize in adding Ketamine infusions to help increase your feeling of well being and reduce the terrible pain you've been experiencing. Giving you hope to live a happier and more productive, fulfilled life.
