Understanding Ketamine Benefits and Risks: A Patient Guide

Know the Facts: Important Ketamine Treatment Considerations

Ketamine may offer fast relief for some people living with depression, PTSD, or pain. This guide explains what it does and what to ask before starting.

Ketamine affects the brain differently from most treatments. It works on the glutamate system, which helps with mood, memory, and pain. Some people notice changes quickly, while others may need more time or respond differently.

Studies suggest it may help the brain form new pathways (Translational Psychiatry, 2023), but it can also cause short-term side effects like dizziness or dissociation. This guide walks through the key facts so you can feel more informed when speaking with a provider.

How Ketamine Works in the Brain

Most antidepressants work slowly by changing serotonin levels. Ketamine is different. It targets the glutamate system, which plays a role in how brain cells talk to each other. This can lead to faster changes in mood or pain response.

A 2023 study in Translational Psychiatry showed ketamine may help the brain create new connections - this is called neuroplasticity. It could be one reason some people feel a shift in how they think or feel after treatment.

But it’s not the same for everyone. Effects can be fast, delayed, or mild. Some people feel disconnected or tired afterward. These effects are usually short-term and monitored in a clinic setting.

What a Session Might Feel Like And Why Support Matters

After reading about the science and potential effects, many patients still wonder, what will it actually feel like?

Some people describe ketamine sessions as quiet and introspective. Others say the experience feels emotionally open, or brings a sense of distance from heavy thoughts.

A 2024 study in Current Research in Neuropharmacology found that patients often felt more emotionally aware, or able to reflect in a new way. This state usually lasts a short time, but it can be powerful. For some, it’s calm and clear. For others, it brings up strong feelings that take time to process.

That’s why it helps to have a plan in place - whether it’s talking to a therapist, journaling, resting, or simply having someone check in.

Feeling supported, both during and after treatment, can make a meaningful difference.

The More You Know, the More Confident You Can Feel

Ketamine therapy isn’t one-size-fits-all.

Some people feel a shift early. Others take longer, or experience only small changes. But what helps everyone is feeling informed, supported, and heard.

This guide is here to walk you through what ketamine therapy is and what it isn’t. It won’t give you answers for everything, but it will help you ask better questions, understand what to expect, and feel steadier if you decide to take the next step.

Ketamine Therapy: 4 Benefits & Risks Every Patient Should Understand

What Are the Benefits of Ketamine Therapy?
‍

Everyone’s experience with ketamine is different. Here are some of the benefits people may notice.

1.

Ketamine Treatment Benefit #1: Relief Can Happen Quickly
Some people feel better within hours of their first treatment, especially those living with depression that hasn’t responded to other options (BMJ, 2022). The effects can be emotional, physical, or both. But not everyone feels a quick change, and that’s okay. Some need more time or more sessions to notice improvement.

2.

Ketamine Therapy Benefit #2: May Help the Brain “Reset”
Ketamine can help the brain become more flexible - this is called neuroplasticity, and it means the brain may form new, healthier patterns. That might look like thinking more clearly, feeling less stuck, or reacting to pain or stress in a new way (CNS Spectrums, 2024). For some people, it opens a helpful window to start healing with therapy, journaling, or reflection.

3.

Ketamine Treatment Benefit #3: May Support Relief From Long-Term Pain
For people with chronic conditions like fibromyalgia or nerve pain, ketamine may help turn down signals that make the body feel pain all the time (Current Treatment Options in Neurology, 2014). While it doesn’t work for everyone, some patients describe feeling more comfortable for the first time in years.

4.

Ketamine Therapy Benefit #4: Sessions Can Be Insightful
Some people describe ketamine as helping them step back from difficult thoughts or emotions. A 2024 study found that patients often felt calmer or more able to reflect on their experiences (Current Research in Neuropharmacology). It’s not a hallucinogen, but it may create space for emotional awareness and new understanding.

What Are the Risks of Ketamine Therapy?
‍

Everyone’s experience with ketamine is different. Here are a few risks it’s important to understand before starting.

1.

Ketamine Therapy Risk #1: Everyone Responds Differently
Ketamine doesn’t work the same way for every person. Some feel better right away. Others don’t notice much at all. It’s important to know that this is normal and not a sign of failure. Progress, if it happens, can take time and follow-up care.

2.

Ketamine Treatment Risk #2: Some Side Effects Are Common
During or after treatment, you might feel dizzy, disconnected, nauseous, or like your thoughts are drifting. These are called short-term side effects and are usually closely monitored in a clinic. They tend to pass within a few hours (Mayo Clinic Press), but they can feel unfamiliar the first time.

3.

Ketamine Therapy Risk #3: Costs Can Add Up
Ketamine therapy is not always covered by insurance. That means many patients pay for treatment themselves. Ask clinics if they offer payment plans or sliding scale fees—it’s okay to talk about what’s realistic for you.

4.

Ketamine Treatment Risk #4: Support After Treatment Makes a Difference
Ketamine may open a window where thoughts and emotions feel more active. This can be helpful—but also intense. Having support like a therapist, a journal, or a calming routine can help you make the most of that time. Without follow-up, some of the benefits may fade faster.
