Do Doctors Prescribe Ketamine for Pain Management?
Chronic pain can be debilitating, impacting every aspect of a person's life. When traditional treatments fail, many seek alternative options, leading to the question: do doctors prescribe ketamine for pain? The answer is nuanced.
Ketamine, an anesthetic used in surgery and emergency medicine, has shown promise for certain chronic pain types, especially neuropathic pain. So, do doctors prescribe ketamine for pain? Yes, but with important considerations.

When Do Doctors Prescribe Ketamine for Pain?
Ketamine isn't a first-line treatment. Doctors typically prescribe ketamine when other options like antidepressants, anti-epileptics, and opioids haven't worked.
This off-label ketamine use for pain management has grown, leading to specialized ketamine clinics. But how effective is ketamine, and what are the risks?
Ketamine for Neuropathic Pain
Neuropathic pain, caused by nerve damage, is one area where ketamine can be effective. Ketamine blocks the N-methyl-D-aspartate (NMDA) receptor, crucial for pain signaling. This action, coupled with its anesthetic properties and potential for new neural synapse development, is thought to reduce pain intensity.
Conditions like complex regional pain syndrome (CRPS) and postherpetic neuralgia may benefit. Ketamine administration via infusions can provide short-term pain relief. However, long-term ketamine studies are ongoing.
Ketamine for Other Types of Pain
While neuropathic pain is where ketamine shows most promise, doctors might explore ketamine for other pain syndromes. These include fibromyalgia, cancer pain, and other difficult-to-manage issues when other pain management strategies aren't suitable.
Ketamine treatment is not a first choice due to potential adverse effects but is a possible alternative to other last resorts. It's often given with opioid blockers.
Risks and Side Effects of Ketamine for Pain
Even at pain-relieving doses, ketamine can have side effects such as hallucinations, memory problems, panic, nausea, sleepiness, and heart rate changes. Rare but serious complications include liver problems. Some doctors also worry about addiction, given ketamine’s opioid-like activity, though this is not well understood.
A high dose of ketamine carries the risk of death due to its hallucinatory effects. Ketamine should only be used under careful supervision. It can also be administered intravenously.
Administering Ketamine for Pain: Clinics vs. Telehealth
Traditionally, ketamine treatment occurred in controlled settings like hospitals or clinics under medical supervision. However, some patients receive ketamine prescriptions via telehealth, raising concerns about reduced oversight and the potential for misuse. While telehealth offers wider access and potentially lower costs, it introduces risks tied to limited doctor supervision.
Some worry that relaxed telehealth requirements for receiving ketamine could mirror issues that fueled the opioid crisis. Overprescribing, a concern during the COVID-19 pandemic, can have negative consequences. Many also discuss who can prescribe ketamine, such as a Nurse Practitioner vs. Psychiatrist, and who can administer it, as online clinics emerge.
Long-Term Use of Ketamine for Chronic Pain Management
Much of our ketamine knowledge comes from short-term use in emergencies or surgeries. Research is exploring long-term effects, focusing on infusions lasting four to fourteen days with follow-up, low doses for temporary relief, and transitioning from mental care to post-acute treatment. Relapse into chronic pain is possible after stopping ketamine.
Conclusion
Do doctors prescribe ketamine for pain? Yes, particularly for nerve-related pain when other treatments fail. However, it’s not a simple solution. Real risks exist, including mind-altering side effects, potential addiction, and limited data on long-term use and effects of ketamine.
Lessons from over-prescribing narcotics should be applied to ketamine. Discussing ketamine with a medical professional is crucial before considering it for pain patients. Patients should research and gather information on randomized controlled trials regarding ketamine before making any decisions.
