Yes, Sweating is a Documented Side Effect of Trintellix (Vortioxetine)
Sweating (hyperhidrosis) is explicitly listed as a known adverse effect of Trintellix in the FDA drug label, occurring both as a common side effect during treatment and as part of discontinuation syndrome when stopping the medication. 1
Evidence from FDA Drug Label
The official FDA prescribing information for Trintellix clearly identifies sweating in two distinct contexts:
During Active Treatment
- Serotonin syndrome warning: Sweating is listed as one of the key symptoms of serotonin syndrome, a potentially life-threatening condition that can occur with Trintellix, particularly when combined with other serotonergic medications. The syndrome presents with sweating, flushing, hyperthermia, and other autonomic symptoms 1
During Discontinuation
- Discontinuation syndrome: When stopping Trintellix suddenly, sweating is specifically mentioned as one of the withdrawal symptoms that may occur. This emphasizes the importance of gradual dose tapering rather than abrupt cessation 1
Supporting Clinical Evidence
A 2015 guideline on antidepressant management confirms that sweating is a commonly reported adverse effect across second-generation antidepressants (including SSRIs, SNRIs, and multimodal agents like vortioxetine), affecting approximately 63% of patients who experience at least one adverse effect during treatment 2
Research literature corroborates this finding, with multiple studies noting hyperhidrosis among the most common adverse events reported with vortioxetine, alongside nausea, vomiting, headache, dizziness, and gastrointestinal symptoms 3
Clinical Implications
Important considerations:
- Sweating from Trintellix is generally manageable and does not typically require discontinuation
- If sweating occurs with other symptoms (agitation, confusion, fast heartbeat, high fever, muscle rigidity), seek immediate medical attention as this may indicate serotonin syndrome 1
- Gradual dose reduction when discontinuing can minimize withdrawal-related sweating 1
- The multimodal receptor profile of vortioxetine does not eliminate this serotonergic side effect, though overall tolerability remains favorable 3
