What are the Ketamine Maintenance Protocols?

Please note that throughout this blog, we may refer to ketamine, esketamine, and Spravato relatively interchangeably. This is due to the inherent similarities in chemical makeup between ketamine and esketamine, and their similar effects on mental health conditions. In the event that this creates confusion, don't hesitate to reach out to Lumin Health staff to ask any questions about treatment at hello@lumin.health or by scheduling a free consultation.

Dr. Ben Yudkoff, Co-Founder and Chief Medical Officer at Lumin Health, hosted a Reddit AMA on r/TherapeuticKetamine community on March 6th, 2026\. The below blog post is a recap of one of the questions presented on that AMA, syndicated to the Lumin Health blog in the event that it answers any questions about ketamine therapy, Spravato treatment, or general concerns you may have about treatment.

QuitInevitable 915 asks:

What maintenance protocol do you recommend people after the initial loading phase?

Answer from Dr. Ben Yudkoff, Co-Founder and Chief Medical Officer of Lumin Health:

You're asking the right question, one that’s a little difficult to answer as everyone’s trajectory is so different. I think you’re referencing ketamine treatment (as opposed to esketamine treatment) and I’ll keep my answer to ketamine. If you’d like more info on esketamine, please let me know… Most people begin ketamine treatment at 0.5 milligrams per kilogram (with subsequent changes in dose made on an as needed basis). There are permutations of a person's individual case where that might not be the standard initial dose. Usually in my practice and at Lumin Health, we recommend that people persist in the initial phase, for somewhere between 6 to 10 treatments, often delivered twice weekly.

What I recommend personally to people after the loading dose is to engage some of the uncertainty. There are 2 different models of planning for a response to an initial loading phase (what we call the ‘index course’ – that initial 6 entry treatments).

  1. 1. The first response is to be highly prescriptive about it and recommend, after the index course, a tapering course going from twice weekly to once weekly per week, then every other week for a week or some permutation of that, then perhaps once monthly, which is built off of other models of interventional psychiatry and standard tapering courses. There are other places that say that after your initial phase of treatment, a person should persist with once monthly treatment for boosters as prophylaxis. The FDA has a written guideline for Spravato for example – that administrators like to follow as closely as possible – that is sometimes used when administering ketamine that follows these guidelines.
  1. 2. For ketamine which has a little more flexibility in terms of dosing amounts and schedule, I'm in favour of a different course, which is, first and foremost, listening to what the patient's wishes are and how they want to meet treatment. There's a little bit of a gray zone when it comes to the evidence, and so a lot of the planning around this has to do with a patient's wishes, how planful they are versus how improvisational we are, and also what they've budgeted in terms of the treatments. Because ketamine is typically out of pocket, I tend to be more conservative with recommendations to make sure people aren’t spending unnecessarily or being taken advantage of. Usually I recommend that people pause treatment for around a month after the initial phase and take some time to assess efficacy, see for how long the improvement lasts. I tend follow a more improvised approach: how long does the benefit last, is there regularity in the return of symptoms, and build a follow up protocol based on that. That said, many of the patients I’ve been lucky enough to treat prefer to, anticipatorily, have a set maintenance schedule to protect against a return of symptoms. Most usually, in this particular circumstance, I start out recommending monthly treatments and then to increase/decrease the frequency of response once we have a little more experience evidence of how the treatments are going.

A quick word on some of the underlying thinking here: Given the high costs of ketamine therapy, we at Lumin Health strongly believe that accessible care requires easy, effective insurance verification and suggesting, if possible, insurance-based treatments, like Spravato. To put this in perspective, in Massachusetts, if someone is eligible for Spravato it can reduce patients’ costs to typically $10 to $25 per visit (a copay, basically), instead of the typical $500+ for a ketamine infusion. Generally speaking (and I’m sure you know this), and speaking specifically of ketamine \- careful of practices that rigidly adhere to tapers and maintenance. The decision might be appropriate, but it’s a good idea to ask why they have the plan they do and what evidence they base it on. If you can find less expensive alternatives it’s also worth looking into and working with clinics (if you have them in the area) that can explain the options and justifications between suggesting one treatment vs another.

There isn't a single style approach that fits all circumstances \- it’s really a tallying of values and then coming up with a plan. I think the one hazard here for anybody who's considering treatment after the initial loading phase is just making sure that the decisions about what to recommend are not indexed towards the needs of the provider or company at which the person is receiving the treatment – meaning the financial benefits of the company – they should really be evidence-based.

To sum it up: right now, the evidence is gray about what the plan after the index course *should* be. I generally recommend a more open ended approach with ketamine to balance the evidence with also the financial ethics of the treatment. I tend to reserve a priori maintenance dosing to those patients who state that they specifically prefer it, and even in those circumstance work with a person to think of reasonable benchmarks to see how treatment is going and if the plan needs to be modified.
