Vortioxetine Side Effects: What You Need to Know

When you start taking Vortioxetine, a prescription antidepressant used to treat major depressive disorder by balancing brain chemicals like serotonin. Also known as Trintellix, it’s not your average SSRI—its unique action on multiple serotonin receptors makes it different from older meds, but that also means its side effects can be unexpected. You might hear it’s "better tolerated," but that doesn’t mean it’s side-effect-free. People report nausea, dizziness, dry mouth, and sleep changes more often than you’d think. And while some effects fade after a few weeks, others stick around—or worse, signal something serious.

One of the biggest concerns with Vortioxetine is serotonin syndrome, a rare but dangerous reaction caused by too much serotonin in the brain, often from mixing meds. It can happen if you’re also taking another antidepressant, migraine drug like triptans, or even certain painkillers. Symptoms? Confusion, rapid heartbeat, sweating, shivering, muscle stiffness. If you feel this way, don’t wait—get help fast. Then there’s dizziness, which shows up in nearly 1 in 5 users, especially when standing up. It’s not just annoying—it increases fall risk, especially in older adults. And let’s not forget sexual side effects. Even though Vortioxetine is often said to be "sex-friendly," many still report lower libido or trouble reaching orgasm. It’s not universal, but it’s common enough to be a real conversation with your doctor.
