Ketamine FAQ
Ketamine can relieve treatment-resistant depression quickly for some people, but it is not first-line, effects often fade without ongoing care, and it must be supervised. Only esketamine nasal spray is FDA-approved for depression. Beiing never gives doses or recommends clinics; talk to a psychiatrist.

Frequently asked questions
How quickly does ketamine work?
Improvement is often reported within hours to days, much faster than the weeks typical of standard antidepressants. It does not work for everyone.
Is ketamine FDA-approved for depression?
Esketamine nasal spray (SPRAVATO) is. IV ketamine for depression is off-label use of an approved anesthetic. Compounded ketamine is not approved for any psychiatric use.
Is ketamine therapy safe?
In carefully selected patients, in a supervised setting, side effects are usually short-lived. Risks rise without supervision, and long-term data are still limited.
Can ketamine prevent suicide?
Esketamine's label states that it has not been shown to prevent suicide or reduce suicidal thoughts or behavior. If you are in danger, call or text 988 in the U.S. or your local emergency number.
Is at-home ketamine a good idea?
The FDA has warned about compounded ketamine used without proper medical oversight. Ask whether a supervised option is available to you.
Does insurance cover ketamine?
Esketamine is often covered for treatment-resistant depression; off-label IV infusions are frequently paid out of pocket. Ask the provider and your insurer for specifics.
Will ketamine make me hallucinate?
It commonly causes dissociation and perceptual changes, which usually pass within a couple of hours under supervision.
Can I take ketamine if I have bipolar disorder?
Evidence in bipolar depression is limited to small studies, and treatment decisions in bipolar disorder need a specialist. Discuss it with a psychiatrist.
Why doesn't Beiing list doses or clinics?
Doses are a clinical decision for the person treating you, and Beiing stays independent of anyone selling treatment.
