Who Is a Candidate for Ketamine Therapy in Indiana?

This page describes what a responsible clinician typically evaluates — not a yes/no quiz that can tell you whether you qualify. No website can make that determination, including this one.

Who it is usually considered for

Treatment-resistant depression usually means major depression that has not improved after at least two different antidepressant medicines taken at an adequate dose for long enough — often about six to eight weeks each — though exact definitions vary by study and by insurer. as of 30 Apr 2025 · U.S. Food and Drug Administration (source 1, opens in a new tab)Commercial payers and state Medicaid programmes each publish their own prior-authorisation wording; the clinical definition and the coverage definition are not always identical.

The FDA approved Spravato (esketamine) nasal spray on 5 March 2019, for use with an oral antidepressant, for adults with treatment-resistant depression. as of 5 Mar 2019 · U.S. Food and Drug Administration (source 2, opens in a new tab)

On 31 July 2020 the FDA separately approved Spravato, used together with an oral antidepressant, for depressive symptoms in adults who have major depressive disorder with acute suicidal thoughts or behaviour; for this use the oral antidepressant is still required, and it is not a substitute for hospital care when hospital care is needed. as of 31 Jul 2020 · U.S. Food and Drug Administration (source 2, opens in a new tab)

Off-label racemic ketamine is sometimes considered in similar situations when a licensed prescriber judges the evidence and the individual history carefully. That is a clinical judgment, not a consumer product choice.

For depression-specific evidence, see ketamine for depression. For bipolar depression, the evidence and risk profile are different — read ketamine and bipolar disorder before assuming the same path applies.

What “treatment-resistant” means in practice

Insurers and clinics both use the phrase, but they do not always mean the same thing. A clinic may be willing to discuss treatment after two failed antidepressant trials; a payer may still deny coverage until each trial is documented by name, dose, duration and reason for stopping. Bring that documentation to the first assessment if you have it.

Coverage rules for Indiana are on the insurance page — candidacy and coverage are related questions, not identical ones.

Contraindications and cautions a clinician will screen for

Spravato is contraindicated in people with aneurysmal vascular disease, arteriovenous malformation, or a history of intracerebral haemorrhage, and in anyone with a known hypersensitivity to esketamine, ketamine, or excipients — and a careful medical history is required before any ketamine-class treatment because blood pressure commonly rises after a dose. as of 30 Apr 2025 · U.S. Food and Drug Administration (source 1, opens in a new tab)

Spravato carries a boxed warning for sedation, dissociation, respiratory depression, abuse and misuse, and suicidal thoughts and behaviours — the same class of risks that justify the REMS clinic-only distribution system. as of 30 Apr 2025 · U.S. Food and Drug Administration (source 5, opens in a new tab)

None of these bullets is a self-exclusion checklist. Some are hard stops; others are reasons for extra monitoring, a different modality, or waiting. Only the assessing clinician can place you on that map.

What the assessment usually involves

  1. A full psychiatric history, including prior medicines, therapies, hospitalisations and suicidality.
  2. Medical history and often a blood-pressure check; some clinics order labs or an ECG.
  3. A conversation about goals, logistics (rides home, time off work), and cost or insurance.
  4. For Spravato, enrolment in the REMS programme and confirmation the site is certified.
  5. Informed consent that covers dissociation, blood-pressure rise, driving rules and uncertainty of benefit.

When it is not the right option

Ketamine-class treatment is not a first-line antidepressant, not a substitute for emergency care, and not a good fit when the primary problem is untreated mania, unstable medical illness, or a setting that cannot monitor you safely. If you are in crisis right now, use the resources at the top of this page — do not wait for a clinic intake.

If you are in crisis, call or text 988 to reach the 988 Suicide & Crisis Lifeline, or text HOME to 741741 to reach the Crisis Text Line. Both are free and available 24 hours a day. as of 18 Jul 2026 · 988 Suicide and Crisis Lifeline (source 1, opens in a new tab)

Who may assess and prescribe in Indiana

Indiana medical doctors and osteopathic physicians may administer ketamine within their scope of practice. An advanced practice nurse needs a written collaborative practice agreement with a physician plus state and federal controlled substance registrations before prescribing it. A physician assistant may prescribe and administer only what their collaborating physician has delegated. A certified registered nurse anaesthetist may administer anaesthesia only under a physician's direction and in that physician's immediate presence, and has no independent prescribing authority. as of 1 Jan 2026 · Indiana Professional Licensing Agency (source 2, opens in a new tab)

In practical terms, ask who will be in the room, who writes the order, and who is responsible if something goes wrong mid-session. Licence status is public:

Referral norms vary by clinic. Some require a letter from your existing psychiatrist; others will complete a full intake themselves. Neither pattern means this website has referred you — we do not screen, match or book patients.
