A large analysis of 3,870 patients with moderate-to-severe depression, anxiety, or PTSD who used a telehealth program for at-home subcutaneous ketamine found significant symptom reductions after about six weeks. Depression scores on the PHQ-9 fell from 14.6 to 6.3, anxiety scores on the GAD-7 from 13.1 to 6.1, and PTSD scores on the PCL-5 from 46.7 to 27.5, all with large effect sizes. Over 80% of patients achieved a clinically meaningful improvement. Adverse events were low (2.8%-3.2%), and no serious complications occurred. The results suggest that supervised at-home subcutaneous ketamine is a safe and effective option that could expand access to rapid-acting treatment.
