Fibromyalgia Treatment

IV ketamine for fibromyalgia is used off-label — ketamine itself is FDA-approved as an anesthetic, but not specifically for fibromyalgia. The three FDA-approved medications for fibromyalgia are duloxetine, milnacipran, and pregabalin — all of which have well-documented limitations and failure rates for a significant portion of patients. Ketamine’s off-label use for fibromyalgia is supported by published peer-reviewed research, multiple systematic reviews, and a growing body of real-world clinical evidence. At Revitalized Clinic, we are transparent about what the evidence does and does not yet establish.

Because most standard fibromyalgia medications target serotonin, norepinephrine, or voltage-gated calcium channels — peripheral or partial approaches to a condition that is now understood to be driven centrally by NMDA receptor-mediated glutamatergic signaling and central sensitization. Ketamine addresses the central sensitization mechanism directly, which is why it represents a pharmacologically rational next step for patients who have not responded adequately to first-line treatments.

Duration varies significantly by protocol and individual. Single low-dose infusions have generally shown relief lasting hours to a few days in published RCTs. Multi-session protocols with higher cumulative doses, which is what the dose-response research supports, are associated with more sustained benefit. The 2025 retrospective study found complete responders maintained benefit from oral maintenance therapy for a mean of 15.6 months following IV induction. Our team builds maintenance schedules around your documented clinical response.

Research and patient reports suggest that ketamine’s effects in fibromyalgia often extend beyond pain reduction to improvements in sleep quality, mood, energy level, and cognitive clarity. These benefits are consistent with ketamine’s simultaneous action on NMDA receptors, dopamine pathways, and mood-relevant neural circuits. Many fibromyalgia patients report that improvement in sleep quality is among the first changes they notice following treatment.

IV ketamine infusions for fibromyalgia are currently self-pay at Revitalized Clinic, as they remain off-label. We encourage patients to contact their insurer to inquire about possible reimbursement through a superbill. Our team is glad to discuss payment options at your free consultation.
