What the research says.
A quick, data-only summary. The full evidence, dosing, and sources are below.
Prescription serotonin-norepinephrine reuptake inhibitor (SNRI) approved for major depressive disorder, generalized anxiety disorder, social anxiety disorder, and panic disorder. NutriStack rates the supporting evidence as strong. Common adult dosing is 37.5–225 mg daily (as prescribed by your physician), though a prescriber sets the actual dose. With long-term use it can deplete sodium. This profile indexes 10 sources.
The bottom line
Evidence rating strong. Most-documented uses: depression symptom relief, generalized anxiety reduction, social anxiety improvement. 10 sources indexed (1998–2024), with 0 interaction records on file.
How it works, mechanistically.
Core mechanism
Inhibits the reuptake of both serotonin (5-HT) and norepinephrine (NE) by blocking their respective transporters (SERT and NET). At lower doses (75 mg), serotonin reuptake inhibition predominates; norepinephrine reuptake inhibition becomes clinically significant at doses above 150 mg. Weak dopamine reuptake inhibition at very high doses.3,10
Dosing & protocol.
Take with food to reduce nausea. Swallow extended-release capsules whole; do not crush, chew, or dissolve. Taper gradually to minimize discontinuation symptoms.3
What it depletes.
Nutrients this medication can lower over time, and what to replace.
Sodium
ModerateAntidepressant-associated SIADH can increase renal free-water retention and dilute serum sodium, producing hyponatremia.
