Vortioxetine (Trintellix) and Ketamine Therapy | Tovani Health
Trintellix (Vortioxetine) — Multimodal serotonergic antidepressant
Verdict at Tovani Health
Treated like an SSRI for general planning; the historical serotonin syndrome framing has been retired.
Vortioxetine and ketamine are compatible. Pharmacologically vortioxetine acts like an SSRI plus 5-HT receptor modulation. The Veraart 2021 systematic review covering ketamine plus SSRIs and SNRIs found no documented serotonin syndrome at therapeutic doses, so we have retired the older 'brief on serotonin syndrome symptoms' protocol that used to apply here. We do track BP because SNRI-adjacent agents can raise baseline BP that stacks with ketamine's transient pressor response.
If you take Trintellix regularly and are considering at-home ketamine therapy, the combination is safe with monitoring or dose adjustment. This page covers the brief pharmacologic context and what we do at intake.
How Trintellix interacts with ketamine
Vortioxetine inhibits serotonin reuptake and modulates multiple 5-HT receptor subtypes. Ketamine is not meaningfully serotonergic, so combining the two does not produce the SSRI-plus-MAOI style serotonin syndrome concern.
What we do at intake
Disclose dose. We brief patients on the early signs of serotonin syndrome (agitation, tremor, sweating, hyperthermia) and ask them to call immediately if those appear in the 24 hours after a session.

The Veraart 2021 systematic review covering ketamine plus SSRIs and SNRIs found no documented serotonin syndrome at therapeutic doses, so we have retired the older 'brief on serotonin syndrome symptoms' protocol that used to apply here.
