Ketamine

Ketamine comes in several forms. The only one that the FDA has approved as a medication for depression is a nasal spray called esketamine (Spravato). It’s for adults who either haven’t been helped by antidepressant pills, have major depressive disorder, or are suicidal. They continue on their antidepressant and receive esketamine at a doctor’s office or in a clinic, where a health care provider watches over them for 2 hours after the dose.
