Abstract

Antidepressant discontinuation symptoms occur with all classes of antidepressant. A well-described discontinuation syndrome occurs with the selective serotonin reuptake inhibitors, common symptoms including dizziness, headache, nausea and lethargy. Rare antidepressant discontinuation syndromes include extrapyramidal syndromes and mania/hypomania. All these syndromes, even isolated discontinuation symptoms, share three common features that facilitate diagnosis; abrupt onset within days of stopping the antidepressant, a short duration when untreated and rapid resolution when the antidepressant is reinstated. Clinicians need to be familiar with strategies for the prevention and management of such symptoms. Preventive strategies include warning patients about the possibility of discontinuation symptoms, encouraging good antidepressant adherence and tapering antidepressants at the end of treatment. Most symptoms are mild and short-lived. Consequently symptoms that follow planned termination of an antidepressant can often be managed by providing an explanation and reassurance. More severe symptoms should be treated symptomatically or the antidepressant restarted, in which case symptoms usually resolve within 24 h. More cautious tapering can then follow.

  • The HAM-D has been criticised for problems in differentiating between withdrawal and depressive symptoms.

    “However, this scale has been criticised because of its problems in differentiating between withdrawal and depressive symptoms (Fava 2015: Haddad 2007).”

    From Approaches for discontinuation versus continuation of long-term antidepressant use for depressive and anxiety disorders in adults (2021) · cites this paper as Haddad 2007

    The ‘Antidepressant discontinuation symptoms’ and ‘Differential diagnosis’ sections say withdrawal symptoms may be mistaken for recurrent depression and explain how clinicians can distinguish them. They do not mention the HAM-D or criticise its ability to make that distinction. The indexed passages do not specify individual page numbers. (LLM, conf=0.78)

    Experimental — accuracy not yet measured
  • Withdrawal symptoms may be misdiagnosed as relapse when relapse is assessed with the HAM-D scale.

    “Withdrawal symptoms may be misdiagnosed as relapse when relapse is assessed with the HAM-D scale (see above, Overall completeness and applicability of evidence) (Fava 2015: Haddad 2007).”

    From Approaches for discontinuation versus continuation of long-term antidepressant use for depressive and anxiety disorders in adults (2021) · cites this paper as Haddad 2007

    The ‘Antidepressant discontinuation symptoms’ section says withdrawal symptoms may be diagnosed as relapse or recurrence, and ‘Nature of symptoms’ gives recurrence of depression as an example. The cited paper does not link that risk to assessment with the HAM-D scale. (LLM, conf=0.88)

    Experimental — accuracy not yet measured
  • The incidence and severity of SSRI withdrawal appears to be influenced by half-life and receptor affinities, duration and dose of usage, method of tapering, and individual patient characteristics.

    “The incidence and severity appears to be influenced by half-life and receptor affinities, duration and dose of usage, as well as method of tapering, and individual patient characteristics 3,9 .”

    From Tapering of SSRI treatment to mitigate withdrawal symptoms (2019) · cites this paper as [3]

    The introductory passage (p. 447) identifies half-life, pharmacodynamics and individual patient characteristics as determinants of discontinuation symptoms. The Incidence section (page not available in our copy) links higher doses and longer treatment to more symptoms, but says an effect of abrupt stopping versus tapering has not been demonstrated in clinical studies. The paper does not specifically identify receptor affinities as a factor. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Fluoxetine has been routinely identified to cause less severe withdrawal effects than other SSRIs, which has been attributed to its longer half-life.

    “It has been routinely identified to cause less severe withdrawal effects than other SSRIs, which has been attributed to its longer half-life 3,30,75 .”

    From Tapering of SSRI treatment to mitigate withdrawal symptoms (2019) · cites this paper as [3]

    The Incidence section (page unavailable) reports that fluoxetine has the lowest incidence of discontinuation symptoms among SSRIs. The Management section (page unavailable) links fluoxetine’s long half-life to its ability to suppress discontinuation symptoms when patients switch from other drugs. Neither passage establishes that symptoms caused by stopping fluoxetine are less severe than those caused by stopping other SSRIs. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • The most common withdrawal symptoms include dizziness, vertigo, tremor, nausea, insomnia, fatigue, mood dysregulation, anxiety, panic, irritability and agitation.

    “The most common symptoms include dizziness, vertigo, tremor, nausea, insomnia, fatigue, mood dysregulation, anxiety, panic, irritability and agitation (Fava et al., 2015; Haddad and Anderson, 2007; Jha et al., 2018).”

    From Post-acute withdrawal syndrome (PAWS) after stopping antidepressants: a systematic review with meta-narrative synthesis (2025) · cites this paper as Haddad and Anderson, 2007

    The Incidence section’s symptom list includes dizziness, vertigo, tremor, nausea, insomnia, lethargy, low mood, irritability, and anxiety/agitation. But the Primary SSRI discontinuation syndrome section identifies only dizziness, nausea, lethargy, and headache as the most common symptoms; it does not list panic. The citation therefore supports much of the symptom list, but not the claim that all listed symptoms are among the most common. (LLM, conf=0.88)

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.
