Vortioxetine
Generic: vortioxetine hydrobromide · Brand: Trintellix® · Class: SMS (Serotonin Modulator)
🧠
How It Works
Vortioxetine is a serotonin modulator and stimulator (SMS) — one of the newest and most complex antidepressants available. It works through multiple serotonin pathways simultaneously: it inhibits serotonin reuptake like an SSRI, while also acting as an agonist, partial agonist, or antagonist at different serotonin receptor subtypes. This multi-modal action is thought to explain its unique benefits for cognitive function — including memory, concentration, and processing speed — which often improve beyond what other antidepressants achieve.

Important Safety Information
Black Box Warning (under 25): Antidepressants may increase risk of suicidal thinking in children, adolescents, and young adults especially in the first few weeks. Monitor closely and contact us right away if new or worsening thoughts of self-harm appear.
Serotonin Syndrome: Can occur when combined with MAOIs, triptans, tramadol, or St. John's Wort. Signs include fever, agitation, rapid heart rate, and muscle twitching — seek emergency care immediately.
Drug Interactions: Do not take with MAOIs. Always share your full medication list with your provider.
Pregnancy & Breastfeeding: Discuss risks and benefits with your provider. Do not stop without consultation.
CYP2D6 Interactions: Vortioxetine is metabolized by CYP2D6. Medications that inhibit this enzyme (like bupropion or some antipsychotics) can significantly raise vortioxetine levels. Always share your full medication list.
