Seaside Ketamine in Encinitas's Cardiff-by-the-Sea district delivers IV and intramuscular ketamine infusion therapy for treatment-resistant depression, PTSD, OCD, and chronic pain from its San Elijo Avenue clinic. The practice pairs sub-anesthetic ketamine protocols with metabolic and functional medicine assessments — including micronutrient panels, cortisol mapping, and gut-brain-axis labs — a dual-track approach that distinguishes it from conventional psychiatric models like those at BOLD Health Medical Group. As an FDA-designated Spravato (esketamine) REMS-certified site, the clinic administers intranasal esketamine under the required two-hour post-dose observation window for patients with documented SSRI and SNRI failure. Ketamine-assisted psychotherapy sessions integrate set-and-setting preparation with guided post-infusion integration, addressing the neuroplasticity window that traditional talk therapy alone cannot access — a model complementary to the meridian-based nervous-system regulation offered at Petal & Point Wellness. Highest-tier protocols utilize weight-based IV racemic ketamine titrated across six-session induction series at 0.5–1.0 mg/kg, with real-time hemodynamic monitoring via pulse oximetry and non-invasive blood pressure cycling.
