Patient Questions about Principium Psychiatry

This 5-question summary is matched to the protocols and conditions Principium Psychiatry treats. Editorial responses are HealingMaps-authored, grounded in our 2026 Ketamine Clinic Intelligence Report.

What ketamine protocols does Principium Psychiatry offer?

Principium Psychiatry offers Spravato and IV ketamine — a 2-protocol practice. Patients can switch between or combine modalities without changing providers. Confirm specific dosing schedules and which protocols are recommended for your condition during your consult.

Does Principium Psychiatry offer Spravato (esketamine)?

Yes — Principium Psychiatry offers Spravato, which means they’re FDA REMS-certified and maintain the required two-hour in-office monitoring window after each dose. Spravato is the primary insurance-covered ketamine option for treatment-resistant depression. Worth confirming the prior-authorization timeline before booking your first session.

Is Principium Psychiatry suited for treatment-resistant depression?

Principium Psychiatry treats depression via Spravato (FDA-approved for TRD), and IV ketamine (off-label, evidence-based). The Spravato pathway is the most likely to obtain commercial insurance coverage. TRD is typically defined as two or more prior antidepressant trials without sufficient response — patients meeting that bar are best candidates here.

Does Principium Psychiatry treat PTSD?

Yes — Principium Psychiatry treats PTSD. Both Spravato and IV ketamine can be used for trauma. Ketamine for trauma differs from depression treatment: dosing is often lower per session, and pairing the protocol with trauma-focused therapy between sessions is common. A reasonable consult question: whether PTSD patients here typically use ketamine alone or alongside an outside therapist.

Can Principium Psychiatry help with anxiety disorders?

Yes — Principium Psychiatry treats anxiety, including generalized anxiety, social anxiety, and panic disorder. The evidence base for ketamine in anxiety is less robust than for depression, but it can be a meaningful option for patients who haven’t responded to SSRIs or benzodiazepines. Worth asking which of their protocols they typically recommend for anxiety-primary patients.
