Abstract

Background: Selective serotonin reuptake inhibitors (SSRI) are widely used in medical practice. They have been associated with a broad range of symptoms, whose clinical meaning has not been fully appreciated. Methods: The PRISMA guidelines were followed to conduct a systematic review of the literature. Titles, abstracts, and topics were searched using the following terms: ‘withdrawal symptoms' OR ‘withdrawal syndrome' OR ‘discontinuation syndrome' OR ‘discontinuation symptoms', AND ‘SSRI' OR ‘serotonin' OR ‘antidepressant' OR ‘paroxetine' OR ‘fluoxetine' OR ‘sertraline' OR ‘fluvoxamine' OR ‘citalopram' OR ‘escitalopram'. The electronic research literature databases included CINAHL, the Cochrane Library, PubMed and Web-of-Science from inception of each database to July 2014. Results: There were 15 randomized controlled studies, 4 open trials, 4 retrospective investigations, and 38 case reports. The prevalence of the syndrome was variable, and its estimation was hindered by a lack of case identification in many studies. Symptoms typically occur within a few days from drug discontinuation and last a few weeks, also with gradual tapering. However, many variations are possible, including late onset and/or longer persistence of disturbances. Symptoms may be easily misidentified as signs of impending relapse. Conclusions: Clinicians need to add SSRI to the list of drugs potentially inducing withdrawal symptoms upon discontinuation, together with benzodiazepines, barbiturates, and other psychotropic drugs. The term ‘discontinuation syndrome' that is currently used minimizes the potential vulnerabilities induced by SSRI and should be replaced by ‘withdrawal syndrome'.

  • Antidepressants have been associated with withdrawal symptoms since 1960 for TCAs and MAOs, and since the 1990s for SSRIs and SNRIs.

    “Antidepressants have been associated with withdrawal symptoms since 1960 for TCAs and MAOs (Nilsen 2012), and since the 1990s for SSRIs and SNRIs (Fava 2015; Fava 2018b).”

    From Approaches for discontinuation versus continuation of long-term antidepressant use for depressive and anxiety disorders in adults (2021) · cites this paper as Fava 2015

    The Introduction says case reports began documenting SSRI withdrawal reactions in the 1990s. The Multiple Drug Comparisons section also reports withdrawal symptoms with venlafaxine XR, an SNRI, but does not establish that SNRI withdrawal was documented in the 1990s. The TCA/MAOI portion is attributed to a different citation and is not assessed here; page numbers were not supplied for these passages. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • 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 Fava 2015

    The Discussion says withdrawal symptoms can be mistaken for signs of depressive relapse, supporting the general difficulty in distinguishing them. It does not identify the HAM-D or criticise that scale specifically (searched: HAM-D and Hamilton Depression Rating Scale). The indexed passages provide no page number. (LLM, conf=0.85)

    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 Fava 2015

    The Discussion (page not provided) says SSRI withdrawal symptoms may be misidentified as signs of impending relapse. It does not link that risk specifically to assessing relapse with the HAM-D scale; searches for “HAM-D” and “Hamilton” found no such passage. (LLM, conf=0.86)

    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 [9]

    The Introduction (p. 72) says withdrawal prevalence differs by SSRI pharmacological profile, and Withdrawal Symptoms in Retrospective Studies (page not provided) reports more symptoms with shorter-half-life SSRIs and with abrupt rather than tapered discontinuation. The Discussion (page not provided) mentions possible genetic vulnerability but says specific patient characteristics associated with vulnerability are not established. The copy does not establish receptor affinities, treatment duration, or dose as influences on withdrawal incidence or severity. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • SSRI withdrawal has been attributed to a relative deficiency of serotonin in the context of widespread adaptation of serotonergic receptors.

    “Although the details remain to be elucidated, SSRI withdrawal has been attributed to a relative deficiency of serotonin in the context of widespread adaptation of serotonergic receptors 9,49,64 .”

    From Tapering of SSRI treatment to mitigate withdrawal symptoms (2019) · cites this paper as [9]

    The Discussion (page unavailable in our copy) lists decreased serotonin availability after treatment ends as a suggested mechanism of withdrawal, while emphasizing that the mechanisms remain hypothetical. It does not describe widespread adaptation of serotonergic receptors or link such adaptation to the proposed serotonin decrease. (LLM, conf=0.86)

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Listed symptoms fall below the stated reporting threshold

    Minor

    The text says only symptoms occurring in more than 10% of patients were reported, but the ensuing list includes symptoms reported in 5.6%, 6.9%, and 4.2%.

  • Percentage for persistent symptoms does not match the affected group

    Minor

    Nine patients experienced a discontinuation syndrome. If symptoms persisted in three of them, the proportion is 33.3%, not 27%.

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.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-11.
