After an initial series of ketamine infusions (typically 6 treatments over 2 to 3 weeks), we often see results sustained for about 3 to 5 weeks before a patient will benefit by a maintenance infusion. Results can vary from person to person, with some people returning for maintenance treatments like clockwork and others coming more occasionally for a touch-up maintenance treatment and even an additional series of treatments from time to time. This can be due, in part, to the nature of your symptoms and whether they are more chronic, for instance, or more acute – and may be affected by a host of other factors.
If you’re experiencing things such as changes in medications, are going through an unstable family situation, have a job loss or a medical situation, you may get less than 3-5 weeks of benefit between maintenance treatments. However, if things are going well for you and you’re able to make a lot of positive lifestyle changes, you may get more than 3-5 weeks of benefit.
