What this is
Useful when depression coexists with pain or fatigue. Venlafaxine discontinuation can be particularly severe — taper cautiously, sometimes cross-titrate to fluoxetine. Duloxetine has FDA pain indications (diabetic neuropathy, fibromyalgia, chronic musculoskeletal pain).
Mechanism
Block both serotonin and norepinephrine reuptake; pain and fatigue indications in addition to depression/anxiety; venlafaxine primarily serotonergic at low doses, adds norepinephrine >150 mg
Dose & route
Venlafaxine 37.5-300 mg XR; duloxetine 30-120 mg PO daily
