Quick Reads
How Fast Does Ketamine Work for Depression?
Low-dose ketamine can produce antidepressant effects within hours, with most patients noticing improvement in 1 to 4 hours after an IV infusion.
How Long Do Ketamine's Antidepressant Effects Last?
The antidepressant effects of a single ketamine infusion typically last 3 to 14 days, with repeated treatments extending the duration of benefit.
What Is the Response Rate for Ketamine Therapy?
Approximately 50 to 70 percent of patients with treatment-resistant depression respond to a course of low-dose ketamine infusions.
Does Ketamine Work for Anxiety?
