Antidepressant Withdrawal and Rebound Phenomena
A systematic review
; ; ;
Background: Antidepressants are among the most commonly prescribed drugs worldwide. They are often discontinued, frequently without the knowledge of the prescribing physician. It is, therefore, important for physicians to be aware of the withdrawal and rebound phenomena that may arise, in order to prevent these phenomena, treat them when necessary, and counsel patients appropriately.
Methods: This review is based on a comprehensive, structured literature search on antidepressant withdrawal phenomena that we carried out in the CENTRAL, PubMed (Medline), and Embase databases. We classified the relevant publications and reports by their methodological quality.
Results: Out of a total of 2287 hits, there were 40 controlled trials, 38 cohort studies and retrospective analyses, and 271 case reports that met the inclusion criteria. Withdrawal manifestations are usually mild and self-limiting; common ones include dizziness, headache, sleep disturbances, and mood swings. More serious or prolonged manifestations rarely arise. There is an increased risk with MAO inhibitors, tricyclic antidepressants, venlafaxine, and paroxetine; on the other hand, for agomelatine and fluoxetine, abrupt discontinuation seems to be unproblematic. There is also some evidence of rebound phenomena, i.e., of higher relapse rates or especially severe relapses of depression after the discontinuation of an antidepressant.
Conclusion: A robust evidence base now indicates that there can be acute withdrawal phenomena when antidepressants are discontinued. Putative rebound phenomena have not been adequately studied to date. It is recommended that antidepressants should be tapered off over a period of more than four weeks.
Antidepressants are among the drugs most frequently prescribed not only in psychiatry but also other medical specialties. In 2017, 1.49 billion defined daily doses of antidepressants were prescribed in the health insurance system in Germany (not including private prescriptions and hospital treatments) (1). In addition to depression, they have also been approved for other indications such as anxiety and obsessive compulsive disorders. Sound knowledge of the side effects and risks of antidepressant medication is essential in order to inform and treat patients.
Besides adverse drug reactions during antidepressant use, adverse phenomena that occur following treatment discontinuation are increasingly becoming the focus of attention. Withdrawal phenomena of this kind were known as early on as in the early 1960s (2, e1). However, awareness of the significance of this topic remains low despite its considerable relevance. It is likely that a third of patients discontinue antidepressant medication within 1 month and 50% of patients by the end of the third month (e2), often without consulting their treating physician. A Danish study showed that the most frequent calls to a national medical advice hotline were accounted for by inquiries relating to antidepressant withdrawal phenomena (e3). It is essential, therefore, to provide patients at the start of treatment with relevant information on the risks of abrupt discontinuation, as recommended by the German clinical practice guidelines on unipolar depression (3).
If adverse symptoms occur following discontinuation (or dose reduction) of treatment, a distinction needs to be made between withdrawal syndrome, rebound phenomena, and re-emergence of the primary disorder (Table 1).
An accurate differential diagnosis is important, since it has crucial clinical consequences. For example, in the case of transient withdrawal phenomena, one can usually take a wait-and-see approach or treat symptomatically. In the case of disease recurrence, on the other hand, medication may need to be resumed. If pharmaceutical drugs are actually known to be associated with a risk of rebound following discontinuation, this needs to be taken into account as early on as at the time of making the indication and providing patient information.
A comprehensive and structured database search was carried out (JH) in CENTRAL, PubMed (Medline) (up to January 2017) and Embase (up to April 2017) (eBox). Manual searches were also carried out and the references in relevant articles assessed. All controlled studies, cohort studies, observational studies, case series, and case reports on antidepressant withdrawal and rebound phenomena in subjects aged over 18 years were included. The included studies were classified according to methodological quality (JH) (eTable 1).
Once duplicates had been excluded, the literature search yielded 2287 hits, 349 of which met the inclusion criteria. These included 40 controlled studies, 38 cohort studies and retrospective analyses, and 271 case reports. The eFigure shows the PRISMA flow chart.
Acute discontinuation syndrome/withdrawalsyndrome
A separate syndrome has now been defined in English-speaking countries in relation to antidepressants: antidepressant discontinuation syndrome (ADS). There is a standardized checklist, discontinuation-emergent signs and symptoms (DESS), which lists the symptoms described in the literature and is used as standard in numerous studies (4, e4). A number of symptoms can resemble the primary disease (depression: e.g., anxiety, suicidal thoughts), whereas others can be clearly differentiated from the disorder (e.g., electric shock-like paresthesia, diarrhea). Table 2 provides an overview of the clinical picture of ADS.
The mnemonic aid used in English, FINISH, helps in its timely identification (e5):
- Flu-like symptoms
- Insomnia (disturbed sleep, vivid dreams/nightmares)
- Imbalance (vertigo, light-headedness)
- Sensory disturbances (electric shock-like sensations, dysesthesia)
- Hyperarousal (anxiety, agitation, irritability, etc.)
Box 1 summarizes the characteristics of ADS. Different specific features are seen depending on the drug.
Selective serotonin reuptake inhibitors
A sufficiently large number of methodologically high-quality studies are available on selective serotonin reuptake inhibitors (SSRI; evidence level I and II according to eTable 1). With its especially long half-life, fluoxetine is particularly unproblematic, even in the case of abrupt discontinuation (7, 8). Sertraline and in particular citalopram and escitalopram pose low risk. Studies revealed no significant benefit for tapered withdrawal compared to continuing the medication (9), while abrupt discontinuation carries low risk (approximately 20% compared to 10% in the continuation arms) (10, 11).
Paroxetine is associated with a high risk for ADS compared to other SSRI and, in the case of abrupt discontinuation, ADS symptoms are seen in over 30% of patients (7, 12, 13). With the exception of paroxetine, which causes ADS symptoms more closely resembling those seen with tricyclic antidepressants in terms of frequency and severity (14), SSRI-related ADS is generally mild and self-limiting.
Selective serotonin and noradrenaline reuptake inhibitors
There is robust evidence (level I and II) on selective serotonin and noradrenaline reuptake inhibitors (SNRI). Venlafaxine (and desvenlafaxine) carry a higher risk for ADS (15) compared to both the SNRI duloxetine (e6) and SSRI (escitalopram, sertraline) (13, e7, e8). Venlaflaxine also appears to more frequently cause severe forms of ADS (e8). Moreover, this appears to be the case with particularly early onset withdrawal symptoms (according to some case reports, as early on as after a delayed dose), which can be linked to the drug’s extremely short half-life (Box 1). Duloxetine carries a low risk for ADS (e6) in comparison; this, however, rises in the high-dose range (120 mg/day; e9). The third SNRI, milnacripran, showed no ADS symptoms in a methodologically high-quality study (level I, in the psychosomatic indication “fibromyalgia”) even upon abrupt discontinuation (16). Similarly, an open study revealed only isolated occurrences of anxiety (e10).
The evidence on tricyclic antidepressants (TCA) is limited, and there are only a handful of methodologically high-quality studies (level I and II), some with very low case numbers. However, these point to a high risk for ADS. Even when amitriptyline was tapered out gradually, 80% of patients exhibited symptoms (N = 15), albeit primarily mild and self-limiting (17). Imipramine was comparable to the SSRI paroxetine (14). Methodologically weak studies and case series (level III and IV) yield evidence that there is a risk for severe effects following discontinuation of TCA (18). Symptoms related to cholinergic overdrive are clinically characteristic (2).
There are only case reports and two studies of low methodological quality on MAO inhibitors (MAO-I) (19, e11, e12). Taking these methodological limitations into account, MAO-I appear to be associated with a particularly high risk for ADS; severe courses appear to be more common. Delirium was described in 50% of case reports on ADS following discontinuation of tranylcypromine (19).
A number of methodologically high-quality studies (level I) demonstrate that ADS does not occur even following abrupt discontinuation of agomelatine (20–22).
Mirtazapine and bupropion
Although studies are lacking, a handful of case reports suggest that discontinuation of mirtazapine and bupropion can also cause ADS (e13–e15) (Table 3).
Severe cases of ADS
Uncontrolled studies and (online) surveys suggest higher incidence rates of antidepressant withdrawal effects in general, as well as more severe symptoms (23). However, one needs to take into consideration the methodological limitations and the danger of incorrectly attributing causality to associations. For example, blinded randomized controlled trials revealed equally high rates of withdrawal symptoms in the control arms (>30%), i.e., in which the antidepressant was continued (9, 15). Controlled, high-quality studies point to a primarily self-limiting course involving mild symptoms. In rare cases, symptoms that were classified as more severe were seen. These were mainly sleep disorders and nervousness/anxiety (desvenlafaxine ). Severe courses involving extrapyramidal motor symptoms (such as parkinsonism and akathisia) or paradoxical activation/mania are known from methodologically weaker studies and case reports. These were described following discontinuation of tricyclic antidepressants (e11, e16), MAO inhibitors (19, e17), SSRI (e18–e20), venlafaxine (e21, e22), and mirtazapine (e13) in patients with uni- and bipolar disorders, as well as symptoms that are of particular clinical relevance such as suicidal thoughts (25). The sensation of electric shocks experienced by patients as particularly impairing (especially with SSRI and venlafaxine) is a specific aspect worthy of note (26, e23).
Rebound phenomena refer to the organism’s increased susceptibility following drug discontinuation—comparable to the image of a ball which, when pushed under water and suddenly released, not only returns to the surface, but actually rises out of the water: the symptoms of the underlying disease return to a greater extent than prior to drug initiation, or there is a greater risk of relapse compared to patients that did not receive medication.
Individual case reports and case series report persistent depressive syndrome following antidepressant discontinuation—more severe in nature compared to before starting medication or with additional psychopathological symptoms, some of which are challenging to treat (6). Some authors define these as persistent post-discontinuation syndromes if symptoms persist for longer than 6 weeks (6, e24). Anxiety and panic disorders, sleep disorders, and cyclothymic/bipolar disorders have been reported following discontinuation of paroxetine, escitalopram, citalopram, and fluvoxamine, whereby paroxetine appears to harbor a particularly high risk (6, 27, e25–e27). The available evidence does not permit any statements to be made on the frequency of rebound phenomena. There is only one open and uncontrolled study in this regard, which describes persistent mood swings following discontinuation of paroxetine in three of 20 patients (27).
Our literature search does not systematically answer the question of whether an increased risk of recurrence following discontinuation can be demonstrated. However, a 2011 meta-analysis (28) showed that depressive patients who experienced remission with antidepressants relapsed more frequently following discontinuation (42.0%–55.6%) than did those that experienced remission with placebo (24.7%). The risk was higher for antidepressants that alter monoaminergic neurotransmission more strongly, i.e,. in particular MAO-I and TCA. The risk of relapse is particularly high in the first 6 months following discontinuation (e28). Evidence suggests that the risk of relapse is higher the longer the drug was previously taken (e29). However, the reliability of this evidence from secondary analyses is limited due to study design (e.g., separate observation of study arms). Given its considerable clinical relevance, the topic urgently requires further research.
The minimum treatment duration required for the development of withdrawal phenomena has been insufficiently demonstrated; at least 4 weeks appear to be necessary (e30). There is robust evidence for SSRI and SNRI that there is a risk of ADS from 8 weeks, and that this risk does not change to any relevant extent with longer treatment (7, e4, e9, e31–e33). ADS appears to develop irrespective of the primary disorder (e31, e34).
There is insufficient experimental data as yet. The anticholinergic effect of numerous TCA can cause neuroadaptive counter-regulation, as a result of which acetylcholinergic neurotransmission is increased, causing symptoms characteristic of cholinergic overdrive following discontinuation (2). From a clinical perspective, the majority of ADS symptoms correspond to the picture of serotonin syndrome (e35), particularly with SSRI (6) (Table 2), which can be explained at least in part by the particular effects of antidepressants on serotonin transporters. This is due to the fact that a number of antidepressants not only block the serotonin and norepinephrine transporters, but also cause a reduction (and not a counter-regulatory increase) in these transporters when used long term (e36–e38), which may result in persistent serotonin hyperfunction following discontinuation (the transporters reduce the level of serotonin in the synaptic cleft). In animal studies, transporter density only normalized in a delayed manner (e39). A hyper-responsive serotonergic system was also observed in animal studies following SSRI discontinuation (e40). The following appears to apply as a basic principle: the stronger and more directly an antidepressant affects the balance of the neurotransmitter system, the more pronounced the withdrawal and rebound symptoms.
There is a correlation within the drug classes between plasma elimination time of the drugs and severity and time of onset of ADS (7, 8). Thus, antidepressants with a short half-life pose a greater risk for the development of (more severe) withdrawal symptoms (eTable 2). As such, rapid metabolizers likely also pose a greater risk for ADS (29). The onset of discontinuation symptoms appears to occur in around three to five half-lives following discontinuation (e41). An increase in the risk of ADS at higher doses appears to apply only in the high-dose range (duloxetine 120 mg/day; escitalopram 20 mg/day) (e9, e31, 10).
Differentiating between ADS and (re-)emergence of the primary psychiatric disorder is crucial. There is considerable symptom overlap between ADS and a depressive episode or anxiety disorder, as well as a (hypo-)manic episode (Table 2). Misinterpretation of symptoms can result in unnecessary and potentially harmful medication (e.g., if ADS is misinterpreted as a manic episode and subsequently misdiagnosed as a bipolar affective disorder). Likewise, when changing medication, ADS due to the discontinued drug may be incorrectly identified as an adverse drug reaction to the new drug. A guiding criterion when making this differentiation can be the temporal course, which is characterized by early onset as well as fluctuations, and tends to be transient (29). The likeliest time course is onset in the first week following discontinuation and resolution in the second week (11). The fact that ADS is generally more strongly and specifically defined by somatic symptoms, with symptoms untypical for depression such as dizziness, nausea, sensory impairment, and flu-like symptoms, can be used to help in the differentiation (7). Similarly, particular sleep disturbances such as vivid dreams and nightmares point to ADS (29, e35).
Treatment and prevention
The most important treatment approach likely lies in prevention. Since symptoms are mild and self-limiting in the majority of cases, detailed patient education is often sufficient; if necessary, patients can receive symptomatic treatment in the form of hypnotic agents or anti-muscarinic substances for TCA and cholinergic rebound (30). In the case of severe symptoms, the antidepressant can be resumed, which generally leads to complete symptom remission within 24 h (e42, e43). This also applies to extrapyramidal symptoms and paradoxical activation/mania. A gradual tapering can then be undertaken. Although antidepressant tapering is not able to completely rule out the risk of ADS, it appears to reduce its severity (15). A time period of 2 weeks is too short (15, 25)—the German clinical practice guidelines recommend reducing a drug over a period of at least 4 weeks (3). Findings from narcolepsy research even suggest minimum periods of 3 months (e44). Treating physicians should make decisions depending on the particular drug and taper over longer periods in the case of high initial doses and high-risk drugs (Table 3). Fluoxetine has proven itself in case reports as a “rescue” substance for withdrawal symptoms from other SSRI (e45, e46) and venlafaxine (e47). It can be used instead of the discontinued drug if ADS does emerge and then presumably abruptly discontinued after a number of weeks.
Risk of rebound
Signs of rebound phenomena following discontinuation are to be taken seriously; however, these are often challenging to clinically differentiate from a re-emergence of the primary disorder, since this, too, can change in terms of symptoms and severity over its natural course. Depressive syndromes, for example, are often combined with anxiety disorders, and manic episodes of bipolar disorders often emerge in a delayed manner following what originally appeared to be unipolar depression (31–33).
The concern that, once started, an antidepressant can no longer be discontinued due to the risk of sudden, severe, and in some cases treatment-resistant recurrence (34–36) should prompt caution when starting an antidepressant, all the more so in the case of moderate depression, particularly since antidepressants are scarcely superior to placebo here (37–39).
The question of dependence is discussed in Box 2.
A large number of studies on ADS, some of which are of very high quality, are now available. Symptoms are generally mild and self-limiting. MAO-I, tricyclic antidepressants, paroxetine, and venlafaxine carry a higher risk. With the exception of fluoxetine and agomelatine, gradual tapering of all antidepressants is recommended in order to prevent ADS. Not enough research has been carried out as yet on rebound phenomena. Patients should be educated on the risks of discontinuation and possible rebound phenomena at the start of antidepressant treatment.
