It’s hard to predict how long the effects of your ketamine infusion therapy will last. We have found that many patients who only have one or two ketamine infusion therapy sessions find their symptoms return within a short space of time. However, the routine ketamine infusion therapy treatment protocol of six treatments over a two or three week period, followed by a single treatment each week for the next month, provides longer-lasting results. You might need to have booster treatments once you’re feeling better, which could be monthly or just twice a year, depending on your progress.
