Attempting to stop antipsychotic medication: success, supports, and efforts to cope

A qualitative exploration of family members' perspectives on reducing and discontinuing antipsychotic medication

BACKGROUND

Antipsychotics are routinely prescribed to people diagnosed with schizophrenia or psychosis on a long-term basis. Considerable literature explores service users' opinions and experiences of antipsychotics, but studies investigating family members' views are lacking.

AIMS

To explore family members' perspectives on antipsychotics, particularly their views on long-term use, reduction and discontinuation of antipsychotics.

METHODS

Semi-structured interviews were conducted with 11 family members of people experiencing psychosis. Participants were recruited through community support groups and mental health teams. Interviews were analysed thematically.

RESULTS

The majority of family members valued antipsychotic medication primarily in supporting what they saw as a fragile stability in the person they cared for. Their views of medication were ambivalent, combining concerns about adverse effects with a belief in the importance of medication due to fears of relapse. They described a need for constant vigilance in relation to medication to ensure it was taken consistently, and often found changes, particularly reduction in medication difficult to contemplate.

CONCLUSIONS

Findings highlight that family members' attitudes to medication sometimes conflict with those of the people they care for, impacting on their health and the caring relationship. Family members may need more support and could be usefully involved in medication decision-making.

Current strategies for tapering psychiatric drugs: Differing recommendations, impractical doses, and other barriers

While effective ways to prevent withdrawal symptoms from psychiatric drugs remain unclear, a highly accepted clinical approach for treatment discontinuation is to gradually reduce doses over time. The objective of this review is to gather the current strategies for tapering of psychiatric drugs described in the literature and guidelines in an attempt to identify the most promising one. Literature review and search for practice guidelines provided by government agencies and medical organizations were performed. Different strategies for tapering were found: linear tapering, hyperbolic tapering (by exponential dose reduction and pre-established dose-response curves), extended dosing, and substitution for a long half-life drug. The use of guidelines offers support for patients and prescribers, increasing the likelihood of achieving effective drug discontinuation. Nevertheless, the lack of standardization found among the guidelines makes any attempt to reduce or stop the drug very difficult for prescribers. Hyperbolic tapering by exponential dose reduction appears to be the most promising strategy for psychiatric drug discontinuation. Yet, we still face a constant challenge: how to safely obtain flexible doses for the discontinuation of drugs, particularly during the last steps in which lower doses are required. Further studies are needed to reduce the barriers associated with psychiatric drug discontinuation.

How important are informed consent, informed choice, and patient-doctor relationships, when prescribing antipsychotic medication?

BACKGROUND

Antipsychotic medications (APs) are used for people with psychosis diagnoses and, increasingly for other problems and groups.

AIMS

This study examines how APs are prescribed, from the perspective of recipients.

METHODS

757 people, from 30 countries, responded to questions about their experiences with APs, in an online survey.

RESULTS

Most (70%) were told nothing about adverse effects. Fewer than 2% recalled being told about the risks of diabetes, suicidality, sexual dysfunction, or reduced life span. None recalled being told about reduced brain volume or withdrawal effects. Only 28% recalled being offered other treatments; with only 14% offered talking therapies. 46% were not told how long to take the APs; and, of those who were told something, 48% were told to take them forever. Most respondents (76%) were not told how APs work. Only 19% were satisfied with the prescribing process, and only 25% reported a good, or very good, relationship with the prescriber. Information, satisfaction with the process, and the prescriber relationship were all positively related to three self-reported outcomes: reduction of problems the drugs were prescribed for, general helpfulness, and quality of life.

CONCLUSIONS

Steps need to be taken to ensure people prescribed antipsychotics are fully informed, especially about adverse effects and alternatives.

Guidelines for Discontinuation of Antipsychotics in Patients Who Recover From First-Episode Schizophrenia Spectrum Disorders: Derived From the Aggregated Opinions of Asian Network of Early Psychosis Experts and Literature Review

OBJECTIVE

Antipsychotic discontinuation has been a long-standing clinical and medicolegal issue. The Asian Network of Early Psychosis developed guidelines for antipsychotic discontinuation in patients who recover from first-episode non-affective psychosis. We reviewed the existing studies and guidelines on antipsychotic discontinuation to develop guidelines for antipsychotic discontinuation in such patients.

METHODS

We reviewed the relevant studies, reviews, guidelines, and ongoing trials related to antipsychotic discontinuation in patients with first-episode psychosis or schizophrenia. The quality of randomized controlled trials was assessed using the Grading of Recommendations Assessment, Development, and Evaluation approach.

RESULTS

Most studies had low to very low quality, and 2 had moderate quality. All studies, except 1, advised against antipsychotic discontinuation because of higher relapse rates in the antipsychotic discontinuation group (19%-82% at 1-year follow-up) than the treatment maintenance group compared with the maintenance group. Based on expert opinion and Grading of Recommendations Assessment, Development, and Evaluation evidence of trials, guidelines have been recommended for future discontinuation studies on patients with first-episode schizophrenia spectrum disorders.

CONCLUSIONS

Currently, there are no recommendations for antipsychotic discontinuation in patients with first-episode schizophrenia spectrum disorders. However, there is a pressing need to conduct more rigorous research in remitted patients using more stringent criteria of full recovery, which can form the basis of guidelines on when and how antipsychotics should be tapered and discontinued. Studies that evaluate the patient characteristics and biomarkers that predict successful antipsychotic discontinuation are also needed.

The experiences of 585 people when they tried to withdraw from antipsychotic drugs

•

72% of an international sample of 585 antipsychotics users report withdrawal effects when they try to stop taking them.

•

none recall being told anything about withdrawal effects, dependence, rebound psychosis, the need to reduce gradually, by the prescriber.

•

26% report positive effects of withdrawing, such as feeling more alive and more like themselves.

Introduction

Many recipients of antipsychotic drugs try to stop taking them, primarily because of distressing adverse effects. Little research has been undertaken into the withdrawal symptoms that ensue.

Methods

In an online survey 585 antipsychotic users, from 29 countries, who had tried to stop taking the drugs, were asked specific questions about the process and the open question: ‘What were the effects of withdrawing from the medication?’ 44% had a diagnosis in the ‘schizophrenia’ spectrum.

Results

Responding to specific questions, 72% reported classical withdrawal effects of the kind associated with other central nervous system medications, including nausea, tremors, anxiety, agitation and headaches. 52% of these categorized those effects as ‘severe’. 26% had tried four or more times to discontinue, and 23% took at least one year to successfully withdraw completely. In response to the open question, 73% reported one or more withdrawal effects, most frequently, insomnia, nervousness and extreme feelings; 26% reported one or more positive outcomes, most frequently more energy/alive and clearer thinking; and 18% reported psychosis.

Conclusion

These findings are consistent with a small but growing body of literature on this topic. Prescribers need to inform themselves about the nature, frequency and intensity of withdrawal effects from APs, and about withdrawal psychosis. National guidelines, professional bodies’ statements, and drug company information urgently need to be updated to prevent the suffering that can occur when withdrawal is minimised, misunderstood or unsupported.

The subjective effect of antipsychotic medication on trauma-related thoughts, emotions, and physical symptoms: A qualitative study with people who have experienced childhood trauma and psychosis

OBJECTIVES

Among people with psychosis, those with a history of childhood trauma are likely to experience trauma-related symptoms, such as trauma memory intrusions. Irrespective of whether these individuals continue to remember and re-experience trauma, their treatment very often includes alleviating psychotic symptoms through the use of antipsychotic medication. Antipsychotics, while primarily used to treat psychotic symptoms, can influence non-psychotic symptoms and alter how people think and feel. We thus aimed to explore how people with childhood trauma and psychosis experience the effects that antipsychotics have on their (1) thoughts, images, and memories, (2) emotions, and (3) physical responses, related to their childhood trauma.

DESIGN

A qualitative phenomenological research design using semi-structured interviews was implemented.

METHODS

Data were analysed using interpretative phenomenological analysis.

RESULTS

Nineteen participants were interviewed. Two super-ordinate themes were conceptualized. Many participants spoke about the impact of antipsychotics on trauma-related experiences (Theme 1). Some indicated that antipsychotics alleviated the intensity and frequency of trauma-related thoughts, emotions, and physical symptoms. A few others reported that their trauma-related flashbacks, thoughts, and physical symptoms intensified while taking antipsychotics. Participants spoke about the role of antipsychotics in confronting and processing trauma (Theme 2). A few participants reported that by suppressing trauma-related thoughts and emotions antipsychotics prevented them from confronting their trauma.

CONCLUSIONS

The effects of antipsychotics can be subjectively experienced as beneficial or detrimental depending on how they influence trauma-related thoughts, emotions, and physical responses. Intervention studies are needed to determine how people with childhood trauma and psychosis respond to antipsychotic drugs.

PRACTITIONER POINTS

Antipsychotics may alter the way in which people with childhood trauma and psychosis remember and re-experience trauma. These alterations can be beneficial or detrimental, and thus play a role in whether people consider their medication helpful. By suppressing trauma-related thoughts and emotions, antipsychotics can prevent people from confronting their trauma. This may be considered beneficial to some, but other people may need or want to confront their trauma to heal. The effectiveness of trauma-focused psychological therapies may be influenced by the emotional, cognitive, and physiological effects of antipsychotic medications. The ability of antipsychotics to suppress people's trauma memories may contribute to post-traumatic avoidance. People with post-traumatic stress symptoms and psychosis should be provided with psycho-education about post-traumatic avoidance and its role in the maintenance of post-traumatic stress disorder.

Service-user efforts to maintain their wellbeing during and after successful withdrawal from antipsychotic medication

BACKGROUND

It is well-known that attempting antipsychotic withdrawal can be a fraught process, with a high risk of relapse that often leads people to resume the medication. Nonetheless, there is a group of people who appear to be able to discontinue successfully. Relatively little is known about how people do this.

METHODS

A convenience sample of adults who had stopped taking antipsychotic medication for more than a year were recruited to participate in semi-structured interviews through an anonymous online survey that investigated antipsychotic medication experiences in New Zealand. Thematic analysis explored participant descriptions of their efforts to maintain their wellbeing during and after the withdrawal process.

RESULTS

Of the seven women who volunteered to participate, six reported bipolar disorder diagnoses and one reported diagnoses of obsessive compulsive disorder and depression. The women reported successfully discontinuing antipsychotics for 1.25-25 years; six followed a gradual withdrawal method and had support to prepare for and manage this. Participants defined wellbeing in terms of their ability to manage the impact of any difficulties faced rather than their ability to prevent them entirely, and saw this as something that evolved over time. They described managing the process and maintaining their wellbeing afterwards by 'understanding myself and my needs', 'finding what works for me' and 'connecting with support'. Sub-themes expand on the way in which they did this. For example, 'finding what works for me' included using a tool-box of strategies to flexibly meet their needs, practicing acceptance, drawing on persistence and curiosity and creating positive life experiences.

CONCLUSION

This is a small, qualitative study and results should be interpreted with caution. This sample shows it is possible for people who experience mania and psychosis to successfully discontinue antipsychotics and safely manage the impact of any symptoms that emerge as a result of the withdrawal process or other life stressors that arise afterwards. Findings suggest internal resources and systemic factors play a role in the outcomes observed among people who attempt to stop taking antipsychotics and a preoccupation with avoiding relapse may be counterproductive to these efforts. Professionals can play a valuable role in facilitating change.

Viewpoint: do antipsychotics protect against early death? A critical view

In the past 15 years, researchers utilizing prescription databases to assess medication usage have concluded that antipsychotics reduce mortality in patients diagnosed with schizophrenia and other psychotic disorders. These findings stand in contrast to studies in non-psychiatric patients that have found that antipsychotics, because of their adverse effects on physical health, increase the risk of early death. A critical review of the evidence reveals that the worry remains. There is reason to conclude that antipsychotics contribute to the 'mortality gap' between the seriously mentally ill and the general population and that the database studies are plagued with methodological and reporting issues. Most importantly, the database studies tell of mortality rates within a drug-centered paradigm of care, which confounds any comparison of mortality risks when patients are on or off antipsychotics.

Using Open Questions to Understand 650 People's Experiences With Antipsychotic Drugs

Studies of antipsychotic medication, which are increasingly prescribed for a broad range of problems and circumstances, rarely ask the people who take them to describe their experiences with the drugs. In this study, 650 people, from 29 countries, responded, in an online survey, to "Overall in my life antipsychotic medications have been _____?" and "Is there anything else you would like to say, or emphasise, about your experiences with antipsychotic drugs?" Of the total participants, 14.3% were categorized as reporting purely positive experiences, 27.9% had mixed experiences, and 57.7% reported only negative ones. Negative experiences were positively correlated with age. Thematic analysis identified 749 negative, 180 positive, and 53 mixed statements. The 2 positive themes were "symptom reduction" (14) and "sleep" (14), with the majority (153) unspecified. The 4 negative themes (besides "unspecified"-191) were: "adverse effects" (316), "interactions with prescriber" (169), "withdrawal/difficult to get off them" (62), and "ineffective" (11). The adverse effects included: weight gain, emotional numbing, cognitive dysfunction, sedation, akathisia, effects on relationships, and suicidality. "Interactions with prescriber" included lack of information about withdrawal effects, support, or discussion of alternatives. The only mixed theme was "short-term good, long-term bad" (28). Open questions can add to findings from methodologies focused on symptom reduction. Clinicians should pay more attention to the need for respectful and collaborative patient-prescriber relationships. At the point of prescription, this must include providing the full range of information about antipsychotics, including potential benefits and harms, difficulties withdrawing, and information on alternatives treatments such as psychological therapies.

Positive and Negative Effects of Antipsychotic Medication: An International Online Survey of 832 Recipients

Background:

Antipsychotic medication is currently the treatment of choice for psychosis, but few studies directly survey the first-hand experience of recipients.

Objective:

To ascertain the experiences and opinions of an international sample of users of antipsychotic drugs, regarding positive and negative effects.

Methods:

An online direct-to-consumer questionnaire was completed by 832 users of antipsychotics, from 30 countries – predominantly USA, UK and Australia. This is the largest such sample to date.

Results:

Over half (56%) thought, the drugs reduced the problems they were prescribed for, but 27% thought they made them worse. Slightly less people found the drugs generally ‘helpful’ (41%) than found them ‘unhelpful’ (43%). While 35% reported that their ‘quality of life’ was ‘improved’, 54% reported that it was made ‘worse’. The average number of adverse effects reported was 11, with an average of five at the ‘severe’ level. Fourteen effects were reported by 57% or more participants, most commonly: ‘Drowsiness, feeling tired, sedation’ (92%), ‘Loss of motivation’ (86%), ‘Slowed thoughts’ (86%), and ‘Emotional numbing’ (85%). Suicidality was reported to be a side effect by 58%. Older people reported particularly poor outcomes and high levels of adverse effects. Duration of treatment was unrelated to positive outcomes but significantly related to negative outcomes. Most respondents (70%) had tried to stop taking the drugs. The most common reasons people wanted to stop were the side effects (64%) and worries about long-term physical health (52%). Most (70%) did not recall being told anything at all about side effects.

Conclusion:

Clinical implications are discussed, with a particular focus on the principles of informed consent, and involving patients in decision making about their own lives.

Understanding social withdrawal in euthymic bipolar patients: The role of stigma

Social withdrawal acts as a risk factor in mental health, disturbing clinical management and quality of life in euthymic bipolar patients. However, no previous study has analyzed what variables might predict it. We conducted a cross-sectional study in which 49 euthymic bipolar patients were assessed. The analysis showed that taken together, stereotype endorsement, discrimination experience and control over illness as measured by the ISMI, together explained 80.4% of the variability in social withdrawal. In conclusion, an early assessment of self-stigma and perception of control over illness would help euthymic patients to improve their social situation, reducing social withdrawal.

Barriers to stopping neuroleptic (antipsychotic) treatment in people with schizophrenia, psychosis or bipolar disorder

Most guidelines recommend long-term, indefinite neuroleptic (or antipsychotic) treatment for people with schizophrenia, recurrent psychosis or bipolar disorder, on the basis that these medications reduce the chance of relapse. However, neuroleptics have significant adverse effects, including sexual dysfunction, emotional blunting, metabolic disturbance and brain shrinkage, and patients often request to stop them. Evidence for the benefits of long-term treatment is also not as robust as generally thought. Short-term randomised trials show higher rates of relapse among those whose neuroleptic treatment is discontinued compared with those on maintenance treatment, but they are confounded by adverse effects associated with the withdrawal of established medication. Some longer-term studies show possible advantages of medication reduction and discontinuation in terms of improved social functioning and recovery. Therefore, there is a good rationale for supporting patients who wish to stop their medication, especially given the patient choice agenda favoured by The National Institute for Clinical Excellence (NICE). The major barrier to stopping antipsychotics is an understandable fear of relapse among patients, their families and clinicians. Institutional structures also prioritise short-term stability over possible long-term improvements. The risk of relapse may be mitigated by more gradual reduction of medication, but further research is needed on this. Psychosocial support for patients during the process of reducing medication may also be useful, particularly to enhance coping skills. Guidelines to summarise evidence on ways to reduce medication would be useful. Many patients want to try and stop neuroleptic medication for good reasons, and psychiatrists can help to make this a realistic option by supporting people to do it as safely as possible, with the best chance of a positive outcome.

Maintenance treatment for patients with a first psychotic episode

PURPOSE OF REVIEW

To provide an update of recent studies relevant for maintenance treatment with antipsychotic medication after a first psychotic episode (FEP).

RECENT FINDINGS

Despite controversy derived from a follow-up analysis from an earlier study showing that attempted early discontinuation after remission was associated with improved long-term functioning, most other studies support better long-term outcome with continuous maintenance treatment after the first episode. However, the main question is not whether, but for how long maintenance treatment after FEP should be offered. Consistent evidence shows that withdrawal from antipsychotics increases the risk for a relapse or re-hospitalization. On the other hand, maintenance treatment is associated with the risk to develop burdensome antipsychotic-induced side-effects and one should keep in mind that around 20% of FEP will not have a second episode. In this regard, the decision for maintenance treatment for periods above some months must be the result of a comprehensive risk-benefit evaluation during a shared decision-making process.

SUMMARY

There is no replicated evidence that prognosis can be improved by discontinuing antipsychotic medication after a FEP. There is a clear need for additional studies to develop single-subject outcome predictors and to identify long-term efficacy of maintenance treatment beyond relapse (e.g. recovery).

[Subjectivity and autonomy: meanings and narratives with respect to discontinuing psychiatric drugs]

The objective of this work was to reconstruct the meanings and narratives surrounding the process of discontinuing psychiatric drugs, taking into account the strategies used to abandon these drugs and the processes of construction of identity. In 2015, in-depth semi-structured interviews were conducted individually with five people from Santiago, Chile who had experiences of psychiatric diagnosis, who received treatment with psychiatric drugs during eight o more years, and who discontinued the use of psychiatric drugs for at least one year. The results show the existence of institutional barriers which limit the right to abandon treatment; therefore, people do so autonomously through intimate and personal processes utilizing self-help and social support strategies. At the same time, discontinuing psychiatric drugs implies the construction of a "former user" identity, concentrating knowledge in the figure of expert by experience in the mental health field.
