How to Verify a Ketamine Provider Is Legitimate

A common surprise for patients: there is no single, government-issued "ketamine certification."For generic ketamine (IV, IM, or oral) used off-label for depression or pain, no special permit exists beyond a provider's normal medical licensure. That makes knowing what to check even more important.

What Legitimate Ketamine Providers Must Have

  • An active state medical licensein the state where you're treated (MD, DO, NP, PA, or CRNA — mid-level prescribing authority varies by state).
  • DEA registration.Ketamine is a Schedule III controlled substance; the prescribing clinician must hold a DEA registration tied to the clinic's location.
  • For Spravato specifically: REMS certification.Esketamine can only be administered in healthcare settings certified under the FDA's Spravato REMS program, with mandatory post-dose monitoring. This is the one formal federal certification in the field.

Voluntary Credentials Worth Looking For

  • ASKP3 membership— the American Society of Ketamine Physicians, Psychotherapists & Practitioners publishes standards of care and an ethical code. Membership is a positive signal (every clinic in this directory comes from the ASKP3 member directory), though it is not a license.
  • Relevant board certification — anesthesiology, psychiatry, or emergency medicine backgrounds indicate training in sedation and airway management.
  • Ketamine-specific CME training— courses like ASKP3's "Mastering the Essentials" award certificates of completion.

How to Check a Provider in 10 Minutes

  1. Look up their license at docinfo.org(aggregates all US medical boards) and confirm on your state board's site — check status and any discipline.
  2. Confirm identity and specialty in the free NPI Registry (npiregistry.cms.hhs.gov).
  3. For Spravato, confirm the clinic appears in the official Spravato treatment center locator on spravato.com.
  4. Confirm the credentials listed on the clinic's website match what you found.

Red Flags at a Ketamine Clinic

  • Ketamine prescribed or shipped without a real medical evaluation.
  • No licensed clinician present and monitoring during dosing, or no emergency protocol.
  • No physical address, no named providers, or credentials that can't be verified.
  • High-pressure sales tactics or opaque pricing.
  • "No prescription needed" online sellers — illegal for a Schedule III drug.
