Patient Questions about Gateway Clinics

This 4-question summary is matched to the protocols and conditions Gateway Clinics treats. Editorial responses are HealingMaps-authored, grounded in our 2026 Ketamine Clinic Intelligence Report.

What ketamine protocols does Gateway Clinics offer?

Gateway Clinics offers IV ketamine, KAP and IM ketamine — a 3-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 Gateway Clinics offer ketamine-assisted psychotherapy (KAP)?

Yes — Gateway Clinics offers KAP, which combines ketamine dosing with structured psychotherapy during the dissociative window. KAP sessions are longer than standalone infusions and priced accordingly. A reasonable consult question: whether KAP is delivered by a single integrated provider, or by a separate therapist working with the prescribing clinician.

Is Gateway Clinics suited for treatment-resistant depression?

Gateway Clinics treats depression via IV ketamine (off-label, evidence-based), and KAP for trauma-anchored depression. Insurance coverage is rare for IV/KAP — most patients pay out of pocket. TRD is typically defined as two or more prior antidepressant trials without sufficient response — patients meeting that bar are best candidates here.

Can Gateway Clinics help with anxiety disorders?

Yes — Gateway Clinics 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.
