Whether you're struggling with depression, PTSD, anxiety, or chronic pain, ketamine-assisted therapy has now emerged as a breakthrough therapy that can create profound shifts - sometimes in just a single session. Nevertheless, one of the most frequent and perhaps the biggest question most people have is: How many KAT sessions will it take for me to get better?
Well, this answer isn’t the same for everyone. Your journey with ketamine will depend on several factors, including the severity of your symptoms, how your body responds to treatment, and the type of ketamine therapy you receive - whether it’s IV infusions, intramuscular injections, or the FDA-approved nasal spray, Spravato. Some people experience rapid relief after just a few sessions, while others need ongoing maintenance to sustain long-term benefits.
This guide breaks down the standard treatment protocols, how to tell if it’s working, and what to expect in terms of maintenance therapy.
The Standard Ketamine Therapy Protocol
Most ketamine treatment plans follow a two-phase structure:
- The Initial Phase (Induction) – A short, intensive period where multiple sessions are given over a few weeks.
- The Maintenance Phase – Sessions are spaced out to maintain results and prevent relapse.
The most common treatment protocol is six sessions over two to three weeks, but that’s just a starting point.
Phase 1: Induction (First 2-3 Weeks)
The goal of the induction phase is to “reset” the brain by stimulating new neural connections and reducing symptoms quickly.
- Typical Protocol: 6 ketamine sessions over 2-3 weeks
- Frequency: 2-3 sessions per week
- Dosage & Administration: IV infusion (most common), intramuscular (IM) injection, or nasal spray (Spravato)
- Expected Results: Many people feel relief within the first few sessions, but full benefits typically emerge after all six treatments.
Why six sessions?
Research shows that a series of treatments works better than a single dose. The repeated exposure helps strengthen positive brain changes, making results last longer.
However, some people may need more or fewer sessions, depending on their response. That said, it’s critical to receive ketamine therapy in a safe, controlled medical setting. Some people may feel tempted to obtain ketamine illegally and self-administer it in hopes of quick relief - but this is dangerous and potentially life-threatening. Ketamine affects brain chemistry in powerful ways, and using it without medical supervision can lead to serious health risks, including dissociation, addiction, and unpredictable side effects.
Medical professionals carefully monitor dosing, administration, and patient response to ensure safety and maximize therapeutic benefits. If you’re considering ketamine therapy, the safest and most effective way is through a licensed provider who can guide you through the process with proper care and support.
Phase 2: Maintenance Therapy (Long-Term Plan)
Once the induction phase is complete, the goal shifts to maintaining the benefits and preventing relapse.
How Often Are Maintenance Sessions Needed?
This varies from person to person. Some may need a booster session every month, while others can go for several months without one.
- A common maintenance schedule could look like:
- First few months: 1 session every 2-4 weeks
- After 6 months: 1 session every 4-8 weeks
- Long-term: As needed (some people go 3-6 months between sessions)
Factors That Affect How Many Sessions You Need
Not everyone follows the same schedule. Here’s what influences how many ketamine sessions you may need:
1. Your Condition
The number of ketamine sessions you need depends largely on what you're treating:
- Depression & Anxiety: Most people start with the standard six-session protocol, followed by maintenance treatments as needed.
- PTSD: Because trauma can be deeply ingrained, some individuals may require more than six sessions to fully disrupt distressing patterns and find lasting relief.
- Chronic Pain (e.g., CRPS, Fibromyalgia): Pain conditions are often more resistant to treatment, requiring higher doses and extended protocols - sometimes 10 or more sessions to achieve meaningful improvement.
-
2. How You Respond to Treatment
Everyone’s journey with ketamine therapy is unique. Some people notice a difference after just one or two sessions, while others need the full series to experience meaningful relief. Your provider will closely monitor your progress - if there’s little to no improvement after four sessions, they may adjust your dosage or treatment schedule based on their professional expertise and judgment to help you get the best possible results.
3. The Type of Ketamine Therapy You Choose
- IV Infusion: The gold standard backed by the most research - typically involves six initial sessions for optimal results.
- Intramuscular (IM) Injection: Works similarly to IV but with slightly less precision in dosing, which may affect how your body responds.
- Nasal Spray (Spravato): FDA-approved for depression, this option follows a structured schedule - twice a week for the first month, then tapering to weekly or biweekly sessions.
4. Your Lifestyle & Support System
Your long-term results will be stronger if you combine ketamine therapy with:
- Talk therapy – Especially integration therapy, which helps process insights and reinforce positive changes.
- Healthy lifestyle habits – Regular exercise, balanced nutrition, and quality sleep all support brain health and emotional well-being.
- A strong support system – Connecting with friends, family, or support groups can provide encouragement and stability during your healing journey.
How Do You Know When You Need a Booster Session?
The key to long-term success with ketamine is paying attention to your symptoms. In Ketamine-Assisted Therapy (KAT), a booster session refers to a follow-up ketamine treatment after the initial series (usually six sessions) to help maintain the benefits.
Over time, some people may experience a return of symptoms like depression, anxiety, or PTSD. A booster session is given as needed to reinforce the therapeutic effects and prevent relapse. The timing varies - some people need one every few months, while others go longer without one. It depends on individual response, symptom severity, and lifestyle factors.
Signs You Might Need a Booster/Maintenance Session:
✅ Mood dips or increased anxiety
✅ Old thought patterns or trauma responses returning
✅ Reduced motivation or interest in daily activities
✅ Increased suicidal thoughts (if ketamine therapy helped reduce them before)
Some people schedule maintenance sessions proactively, while others wait until they notice symptoms returning. Both approaches can work, but it’s important to discuss with your provider to find the right timing for you.
What If I Want to Stop Ketamine Therapy?
Ketamine isn’t like traditional antidepressants where stopping suddenly can cause withdrawal. However, if you stop treatment, symptoms may gradually return over time.
- If you’ve been stable for months without symptoms, you may not need further treatments.
- If you relapse, you can always restart ketamine therapy - it’s not a one-time chance.
Some patients use ketamine as a short-term reset and don’t need long-term maintenance, while others rely on it as an ongoing tool for mental health.
Final Answer: How Many Sessions Will You Need?
Most people start with six sessions in three weeks and then one session every few weeks to months for maintenance.
Your exact number of sessions depends on:
✔️ Your condition (depression, PTSD, chronic pain)
✔️ How quickly you respond to the treatment
✔️ Whether you combine it with therapy and lifestyle changes
✔️ Your personal maintenance needs
The best way to know for sure? Start with the induction phase, track your symptoms, and adjust as needed.
There’s no magic number - ketamine therapy is about finding the right balance that keeps you feeling better for longer.
