Ketamine is a legally regulated medicinal anesthetic in India and is used in routine anesthetic practice; since 2010 regulators increased supply controls (prescription / Schedule X controls) due to diversion/misuse concerns. In psychiatry it is commonly used off‑label (intravenous, intramuscular or intranasal compounded preparations) in private clinics for treatment‑resistant depression, suicidality and other indications — these private off‑label treatments are typically paid out‑of‑pocket and are not covered under standard public reimbursement schemes. There is not a nationally standardised, publicly reimbursed ketamine‑for‑depression programme; protocols, supervision (psychiatrist vs anesthesiologist), and monitoring requirements vary by provider and state practice. Clinicians and commentators in India explicitly note absence of a legal requirement for anesthetist supervision for sub‑anesthetic psychiatric protocols, but emphasise need for informed consent and structured protocols.
