Patients often describe a brief period after ketamine therapy when patterns feel a little less rigid and new choices feel possible. The brain more readily lays down communication tracks (called “synapses” and, when lots of interconnected synapses exist in an area, a “node” – which further interconnect to become “networks”). These tracks are the fundamental building blocks of how our brain produces thoughts and behaviors. Psychiatrists call this the neuroplasticity window. It isn’t a magic switch. It’s a short stretch where learning may come a bit easier and the tracks that become our thoughts and behaviors are more readily constructed and maintained. This guide offers a step‑by‑step plan so therapists and patients can use that time without pressure.

What the “neuroplasticity window” is in ketamine treatment 

After ketamine treatment, relatively brief changes to glutamate‑mediated signaling support short‑term changes in how the brain learns vis-a-vis the release of hormones that generate the aforementioned synapses. Many patients notice slightly more flexibility, mood improvement, a bit more energy, or a small gap between thought and action. Not everyone experiences this, and intensity varies. At Lumin Health, we approach it as an opportunity, not an obligation or even expectation.

There are two common paths at Lumin Health:

• Esketamine (Spravato) – intranasal ketamine dosing in a certified Spravato clinic with observation. We’ll refer to this as Spravato treatment.
• Off‑label ketamine therapy – intramuscular ketamine dosing in a clinic with medical monitoring and support. Protocols are tailored to the patient.

Safety and scope: who does what

• Lumin Health: dosing, vitals, side‑effect guidance, medication adjustments.
• CBT provider: choosing CBT targets, translating insights into actions, and tracking progress.
• Patient: setting the pace, participating in the choice of directions, and collaborating with providers.

If you’re exploring ketamine for depression, your team can coordinate with your permission. You choose what to share.

A simple 3‑phase micro‑protocol (0–72 hours)

The goal is small and repeatable, not intense or profound.

• Before ketamine dosing: identify one or two specific CBT skills to practice this week. Keep it concrete (e.g., a brief values‑based activity, one cognitive reframing exercise, one exposure step).
  
  
• 24–72 hours after ketamine dosing: schedule a focused psychotherapy or skills session to apply those targets. The goal isisn’t to process everything. It’s to practice one small behavior while your brain may be more flexible.
  
  
• Between ketamine doses: repeat what worked, write down any shifts you noticed, and keep changes small and repeatable.
  
  

This cadence works with Spravato treatment and with off‑label ketamine therapy.

Pick‑one menus (so the work stays connected and advances things with a mind toward pacing)

Behavioral activation (choose one):

• Walk outside for 15 minutes while calling a supportive person.
• Prepare a simple, nourishing meal and eat it at the table.
• Do one admin task you’ve postponed (pay a bill, send an email).
• Schedule one small value‑aligned activity (art, music, faith, service) this week.

Cognitive skills (choose one):

• Identify an all‑or‑nothing thought. Write one balanced alternative. Practice it once.
• Make a two‑column list: Facts I know vs Predictions I’m making. Read it aloud.
• Name the thought trap (catastrophizing, mind‑reading). Ask, What is a 5% more helpful view?
• Identify negative thought patterns directed at the self and provide alternative thoughts.

Exposure ladders (choose one pre‑planned step):

• Send a short message you’ve avoided.
• Sit with a mild trigger for 5 minutes using paced breathing.
• Enter a low‑stakes social space for 10 minutes and see how you feel.

Sleep supports (choose one):

• Fixed wake time for the next 7 days.
• 30‑minute wind‑down with screens off.
• Bed is for sleep only; get up if awake >20 minutes.

It might be worthwhile to pick one item per category, but if that is too much, feel free to pick one category only.

Example two‑week schedule that pairs with ketamine induction

Assume Spravato treatment on Tuesday/Thursday with rides home.

Week 1

• Tue: Spravato dose and observation → quiet evening.
• Wed: Behavioral activation step (10–20 minutes) + one brief cognitive exercise.
• Thu: Spravato dose and observation → quiet evening.
• Fri: psychotherapy or skills coaching.
• Sun: behavioral activation step.

Week 2

• Repeat the same pattern. Keep targets the same unless they are consistently easy. If so, add one small notch only.

If you are receiving off‑label ketamine treatment, adapt the cadence to your dosing days.

Documentation and communication between CBT and ketamine therapy providers

Lumin Health highly values collaboration with providers as treatment happens best when it happens collaboratively – between the patient, the outpatient therapist, the prescriber, and the ketamine/esketamine medical practice. We value the opportunity to communicate openly with providers.

Common pitfalls and how to avoid them

• Too many goals. Limit to one behavior and one thought exercise.
• Turning the window into pressure. Keep the tone light and curious.
  
  

FAQs

What should a session focus on in the first 72 hours?
A short review of one practice, one barrier, and one next step. If deep processing is desired, go at a pace that feels practical, comfortable, and sustainable. 

How soon after dosing can I have therapy?
Most patients prefer sessions 24–72 hours after dosing. Some people prefer to conduct therapy on the same day – each plan is best tailored to the patient’s needs.

Do these steps change with off‑label ketamine treatment?
The structure is similar. Adjust timing to your dosing days and clinic guidance.

What if I feel worse the day after Spravato?
It’s not common. If it happens, call the office for medical guidance. 

Is CBT required for ketamine therapy?
No. CBT is optional. Many patients choose it because it helps them apply gains from ketamine for depression.
