One of the most important questions to ask before starting IV ketamine therapy is how long the results actually last. It is also one where honesty matters most, because the answer is: it depends, and anyone promising permanent results after a single series is overselling. Here is a clear, physician-led explanation from a practice in Greenwood, Indiana of what to realistically expect and why results vary from person to person.

The initial series builds a foundation

Most people start with a series of six infusions over about two to three weeks. Research suggests the benefit builds across this series as it supports neuroplasticity, and many people experience relief that carries beyond the treatment window. How long that relief holds after the initial series varies widely. Some people feel benefits for weeks, others for months. The initial series is best thought of as building a foundation, not as a permanent endpoint.

Why results fade for some people and not others

This is the part few places explain honestly. How long results last depends on individual factors: the nature and severity of your symptoms, your overall brain health, ongoing stressors in your life, and whether you have support in place to reinforce the progress. Ketamine appears to open a window of increased neuroplasticity, but what you do during and after that window matters. People who pair infusions with integration, healthy routines, and ongoing support often sustain their gains longer than those who treat infusions as an isolated event.

How maintenance works

Because effects are not automatically permanent, many people use periodic maintenance infusions to extend and protect their progress. These are spaced according to how you respond, sometimes weeks apart, sometimes months. There is no single schedule that fits everyone, and a good practice builds maintenance around your actual response rather than a fixed formula. The goal is to hold your gains with the least treatment necessary, not to keep you coming in indefinitely.

Making results last

The most durable outcomes tend to come from treating ketamine as part of a larger approach to brain health rather than a standalone fix. Integration support, community, and healthy daily habits all help reinforce the new connections the treatment supports. This is why ongoing support between and beyond infusions is worth considering.
