Abstract

Background: Generalised anxiety disorder (GAD) has received less study than other anxiety disorders, particularly its long-term treatment. Aims: To assess the efficacy and safety of venlafaxine extended release (ER) in patients with GAD. Method: A total of 541 out-patients, 18–86 years old, were recruited to this 24-week, placebo-controlled, double-blind study of three fixed doses (37.5, 75 and 150 mg/day) of venlafaxine ER. Results: All doses of venlafaxine ER showed efficacy superior to placebo, apparent from week 2, that was sustained throughout the 24-week study for the two higher doses. The discontinuation rate did not differ significantly among the treatment groups. Conclusions: Venlafaxine ER is an effective and safe treatment for GAD for up to 6 months.

  • Case reports of new withdrawal symptoms (hypomania, anxiety, restless sleep, nightmares, depersonalization, formication, headache) after discontinuation of trazodone were published.

    “Case reports of new withdrawal symptoms (i.e., hypomania, anxiety, restless sleep, nightmares, depersonalization, formication, headache) after discontinuation of trazodone were published [98-101].”

    From Acute and Persistent Withdrawal Syndromes Following Discontinuation of Psychotropic Medications (2020) · cites this paper as [101]

    The Study rationale mentions trazodone only as a treatment for generalised anxiety disorder. The Adverse events section describes discontinuation symptoms after venlafaxine ER, not trazodone. A search for trazodone withdrawal case reports and the listed symptoms found no passage addressing the claim; page numbers were unavailable in our copy. (LLM, conf=0.76)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
