OBJECTIVE We report a patient who experienced delusional symptoms during gradual discontinuation of low-dose venlafaxine and required antipsychotic treatment. METHOD Case report. RESULTS A 31-year-old woman with major depression had been treated abroad with venlafaxine before returning to Japan. Since venlafaxine is unavailable here, we supplemented her regular venlafaxine dosage of 37.5 mg...

The aim of this double-blind study was to compare the efficacy and safety of venlafaxine vs. fluoxetine in the treatment of patients with depression and anxiety. A total of 146 moderately depressed patients with associated anxiety were randomized to receive 75 mg/d venlafaxine or 20 mg/d fluoxetine for 12 wk. Dose increases were permitted after 2 wk of treatment, to 150 mg/d venlafaxine and 40 ...

CONTEXT Generalized anxiety disorder (GAD) is a chronic disorder in need of reliable data to guide long-term treatment. OBJECTIVES To assess the benefits of 6 and 12 months' treatment of GAD with venlafaxine hydrochloride extended release (XR) in patients who improved after 6 months' open-label venlafaxine XR treatment. DESIGN After 6 months' open-label venlafaxine XR treatment, improved pa...

Venlafaxine is not usually associated with risk of orthostatic hypotension. A 65-year-old US Caucasian female taking 225 mg/day of venlafaxine extended-release developed symptomatic orthostatic hypotension. The systolic and diastolic blood pressure dropped by 25 and 18 mm Hg, respectively, from supine position to standing position within 3 minutes. The patient was otherwise healthy and the orth...

BACKGROUND Duloxetine and venlafaxine extended release (venlafaxine XR) are SNRIs indicated for the treatment of MDD. This study addresses whether duloxetine and venlafaxine XR are interchangeable in their patterns of use with patients who are depressed or are used more selectively based on treatment history, background characteristics, and presenting symptoms. METHODS This was a retrospectiv...

INTRODUCTION Hypertensive encephalopathy with the clinicoradiological entity posterior reversible encephalopathy syndrome in the setting of venlafaxine as single therapy has not been reported earlier. CASE DESCRIPTION A 46-year-old man developed hypertensive encephalopathy associated with venlafaxine as single therapy. Magnetic resonance imaging of the brain, pre and post gadolinium, carried ...

Objective: Traditionally, studies on the non-medical use of pharmaceutical products have focused on controlled substances; e.g., opiates/opioids; and benzodiazepines. Although both bupropion and venlafaxine have been reported as being misused, only anecdotal reports have been made available so far. Hence, the European Monitoring Agency (EMA) Adverse Drug Reactions (ADRs), misuse/abuse/dependenc...

Venlafaxine is the first antidepressant that acts via inhibiting serotonin and noradrenaline reuptake. Hypertension is observed in doses exceeding 300 mg/day and is the most feared complication. We report a patient with accelerated hypertension after venlafaxine use observed at a dose of 150 mg/day. A 23-year-old patient with symptoms of insomnia, depression, anhedonia, fatigue admitted our cli...

OBJECTIVE The present study aimed to determine the intracellular action of the antidepressant, venlafaxine, in C6 glioma cells using heat shock protein 70 (HSP70) immunocytochemistry and HSP70 Western blots; HSP70 is known to be associated with stress and depression. METHODS The extent of HSP70 expression was measured after rat C6 glioma cells were treated with 1) dexamethasone only, 2) venla...
