Bipolar disorder: assessment and management

People have the right to be involved in discussions and make informed decisions about their care, as described in making decisions about your care.

Making decisions using NICE guidelines explains how we use words to show the strength (or certainty) of our recommendations, and has information about prescribing medicines (including off-label use), professional guidelines, standards and laws (including on consent and mental capacity), and safeguarding.

Health and care professionals should follow our general guidelines for people delivering care:

The recommendations cover children, young people and adults with suspected or diagnosed bipolar disorder and apply to bipolar I, bipolar II, mixed affective and rapid cycling disorders.

1.1 Care for adults, children and young people across all phases of bipolar disorder

Treatment and support for specific populations

See NICE's guideline on antenatal and postnatal mental health for guidance on the management of bipolar disorder during pregnancy and the postnatal period and in women and girls of childbearing potential.

1.1.1

Ensure that older people with bipolar disorder are offered the same range of treatments and services as younger people with bipolar disorder. [2014]

1.1.2

Offer people with bipolar disorder and coexisting disorders, such as personality disorder, attention deficit hyperactivity disorder, anxiety disorders or substance misuse, treatment in line with the relevant NICE guideline, in addition to their treatment for bipolar disorder. See NICE's guidelines on antisocial personality disorder, borderline personality disorder, attention deficit hyperactivity disorder, generalised anxiety disorder and psychosis with coexisting substance misuse, be alert to the potential for drug interactions and use clinical judgement. [2014]

1.1.3

Offer people with rapid cycling bipolar disorder the same interventions as people with other types of bipolar disorder because there is currently no strong evidence to suggest that people with rapid cycling bipolar disorder should be treated differently. [2014]

Information and support

1.1.4

Consider identifying and offering assistance with education, financial and employment problems that may result from the behaviour associated with bipolar disorder, such as mania and hypomania. If the person with bipolar disorder agrees, this could include talking directly with education staff, creditors and employers about bipolar disorder and its possible effects, and how the person can be supported. [2014]

1.1.5

Explain and discuss making a lasting power of attorney with adults with bipolar disorder and their carers if there are financial problems resulting from mania or hypomania. [2014]

Support for carers of people with bipolar disorder

1.1.6

Give carers written and verbal information in an accessible format about:

1.1.7

As early as possible negotiate with the person with bipolar disorder and their carers about how information about the person will be shared. When discussing rights to confidentiality, emphasise the importance of sharing information about risks and the need for carers to understand the person's perspective. Foster a collaborative approach that supports both people with bipolar disorder and their carers, and respects their individual needs and interdependence. [2014]

1.1.8

Offer a carer‑focused education and support programme, which may be part of a family intervention for bipolar disorder, as early as possible to all carers. The intervention should:

1.1.9

Identify children, young people and adults at risk of abuse or neglect who are dependent on, living with or caring for a person with bipolar disorder and:

1.2 Recognising and managing bipolar disorder in adults in primary care

Recognising bipolar disorder in primary care and referral

1.2.1

When adults present in primary care with depression, ask about previous periods of overactivity or disinhibited behaviour. If the overactivity or disinhibited behaviour lasted for 4 days or more, consider referral for a specialist mental health assessment. [2014]

1.2.2

Refer people urgently for a specialist mental health assessment if mania or severe depression is suspected or they are a danger to themselves or others. [2014]

1.2.3

Do not use questionnaires in primary care to identify bipolar disorder in adults. [2014]

Managing bipolar disorder in primary care

1.2.4

When working with people with bipolar disorder in primary care:

1.2.5

Offer people with bipolar depression:

1.2.6

Psychological therapists working with people with bipolar depression in primary care should have training in and experience of working with people with bipolar disorder. [2014]

1.2.7

Do not start lithium to treat bipolar disorder in primary care for people who have not taken lithium before, except under shared‑care arrangements. [2014]

1.2.8

Do not start valproate in primary care to treat bipolar disorder. [2014]

1.2.9

If bipolar disorder is managed solely in primary care, re‑refer to secondary care if any one of the following applies:

Physical health

1.2.10

Develop and use practice case registers to monitor the physical and mental health of people with bipolar disorder in primary care. [2014]

1.2.11

Monitor the physical health of people with bipolar disorder when responsibility for monitoring is transferred from secondary care, and then at least annually. The health check should be comprehensive, including all the checks recommended in recommendation 1.2.12 and focusing on physical health problems such as cardiovascular disease, diabetes, obesity and respiratory disease. A copy of the results should be sent to the care coordinator and psychiatrist, and put in the secondary care records. [2014]

1.2.12

Ensure that the physical health check for people with bipolar disorder, performed at least annually, includes:

1.2.13

Identify people with bipolar disorder who have hypertension, have abnormal lipid levels, are obese or at risk of obesity, have diabetes or are at risk of diabetes (as indicated by abnormal blood glucose levels), or are physically inactive, at the earliest opportunity. Follow NICE's guidelines on hypertension, lipid modification, prevention of cardiovascular disease, obesity, physical activity and preventing type 2 diabetes. [2014]

1.2.14

Offer treatment to people with bipolar disorder who have diabetes and/or cardiovascular disease in primary care in line with NICE's guidelines on type 1 diabetes in adults: diagnosis and management, type 2 diabetes in adults: management and lipid modification. [2014]

1.3 Assessing suspected bipolar disorder in adults in secondary care

1.3.1

Assessment of suspected bipolar disorder, and subsequent management, should be conducted in a service that can:

1.3.2

When assessing suspected bipolar disorder:

1.3.3

Take into account the possibility of differential diagnoses including schizophrenia spectrum disorders, personality disorders, drug misuse, alcohol‑use disorders, attention deficit hyperactivity disorder and underlying physical disorders such as hypo‑ or hyperthyroidism. [2014]

1.3.4

If bipolar disorder is diagnosed, develop a care plan in collaboration with the person with bipolar disorder based on the assessment carried out in recommendation 1.3.2 as soon as possible after assessment and, depending on their needs, using the care programme approach. Give the person and their GP a copy of the plan, and encourage the person to share it with their carers. [2014]

1.3.5

Carry out a risk assessment in conjunction with the person with bipolar disorder, and their carer if possible, focusing on areas that are likely to present possible danger or harm, such as self‑neglect, self‑harm, suicidal thoughts and intent, risks to others, including family members, driving, spending money excessively, financial or sexual exploitation, disruption in family and love relationships, disinhibited and sexualised behaviour, and risks of sexually transmitted diseases. For the management of risk, follow the recommendations in the section on managing crisis, risk and behaviour that challenges. [2014]

1.4 Managing crisis, risk and behaviour that challenges in adults with bipolar disorder in secondary care

1.4.1

Develop a risk management plan jointly with the person, and their carer if possible, covering:

1.4.2

Offer crisis services to support people with bipolar disorder who are in crisis, in line with recommendations 1.4.1.1 to 1.4.1.4 in NICEs guideline on psychosis and schizophrenia in adults. [2014]

1.5 Managing mania or hypomania in adults in secondary care

Support and advice

1.5.1

Ensure that people with mania or hypomania have access to calming environments and reduced stimulation. Advise them not to make important decisions until they have recovered from mania or hypomania and encourage them to maintain their relationships with their carers if possible. [2014]

Pharmacological interventions

1.5.2

If a person develops mania or hypomania and is taking an antidepressant (as defined by the British National Formulary [BNF]) as monotherapy:

1.5.3

If a person develops mania or hypomania and is not taking an antipsychotic or mood stabiliser, offer haloperidol, olanzapine, quetiapine or risperidone, taking into account any advance statements, the person's preference and clinical context (including physical comorbidity, previous response to treatment and side effects). Follow the recommendations on using antipsychotics. [2014]

1.5.4

If the first antipsychotic is poorly tolerated at any dose (including rapid weight gain) or ineffective at the maximum licensed dose, offer an alternative antipsychotic from the drugs listed in recommendation 1.5.3, taking into account any advance statements, the person's preference and clinical context (including physical comorbidity, previous response to treatment and side effects). [2014]

1.5.5

If an alternative antipsychotic is not sufficiently effective at the maximum licensed dose, consider adding lithium.

Although its use is common in UK clinical practice, in September 2014 this was an off-label use of lithium. See NICE's information on prescribing medicines. [2014, amended 2023]

1.5.6

If adding lithium is ineffective, or if lithium is not suitable (for example, because the person does not agree to routine blood monitoring), consider adding valproate instead. [2014]

1.5.7

Do not start valproate for the first time in people (male or female) younger than 55 years, unless 2 specialists independently agree and document that there is no other effective and tolerated treatment, or there are compelling reasons that the reproductive risks do not apply. Ensure the pregnancy prevention programme is in place if valproate is used in women and girls of childbearing potential. Follow the MHRA safety advice on the use of valproate.

In September 2014 semi-sodium valproate had a UK marketing authorisation for the treatment of mania if lithium is not tolerated or is contraindicated; this was an off-label use of sodium valproate, although its use was common in UK clinical practice. See NICE's information on prescribing medicines. [2014, amended 2023]

1.5.8

If a person develops mania or hypomania and is taking an antidepressant (as defined by the BNF) in combination with a mood stabiliser, consider stopping the antidepressant. [2014]

1.5.9

If the person is already taking lithium, check plasma lithium levels to optimise treatment (see the section on how to use medication). Consider adding haloperidol, olanzapine, quetiapine or risperidone, depending on the person's preference and previous response to treatment. [2014]

1.5.10

If the person is already taking a mood stabiliser as prophylactic treatment, consider increasing the dose, up to the maximum level in the BNF if necessary, depending on clinical response. If there is no improvement, consider adding haloperidol, olanzapine, quetiapine or risperidone, depending on the person's preference and previous response to treatment. Follow the recommendations on using antipsychotics in the section on how to use medication. [2014]

1.5.11

If the person is already taking valproate and develops mania or hypomania, review their treatment including adherence and:

1.5.12

If a woman or girl of childbearing potential is already taking valproate, advise her to gradually stop the drug under medical supervision because of the risk of fetal malformations and adverse neurodevelopmental outcomes after any exposure in pregnancy. Follow the MHRA safety advice on the use of valproate. [2014, amended 2023]

1.5.13

If the clinical presentation is of a mixed affective state, characterised by both manic and depressive symptoms, follow recommendations 1.5.1 to 1.5.12 for the treatment of mania, and monitor closely for the emergence of depression. [2014]

1.5.14

Do not offer lamotrigine to treat mania. [2014]

For a short explanation of why the recommendations were amended in 2023 and full details of the evidence see the evidence review for changes to valproate recommendations after revised MHRA safety advice.

Electroconvulsive therapy

For the treatment of severe mania that has not responded to other interventions, see NICE's technology appraisal guidance on the use of electroconvulsive therapy.

Reviewing treatment for mania

1.5.15

Within 4 weeks of resolution of symptoms, discuss with the person, and their carers if appropriate, whether to continue treatment for mania or start long‑term treatment (see the section on managing bipolar disorder in adults in the longer term in secondary care). Explain the potential benefits of long‑term treatment and the risks, including side effects of medication used for long‑term treatment. [2014]

1.5.16

If the person decides to continue treatment for mania, offer it for a further 3 to 6 months, and then review. [2014]

1.6 Managing bipolar depression in adults in secondary care

Psychological interventions

1.6.1

Offer adults with bipolar depression:

1.6.2

Psychological therapists working with people with bipolar depression should have training in, and experience of, working with people with bipolar disorder. [2014]

Pharmacological interventions

1.6.3

If a person develops moderate or severe bipolar depression and is not taking a drug to treat their bipolar disorder, offer fluoxetine combined with olanzapine, or quetiapine on its own, depending on the person's preference and previous response to treatment.

1.6.4

If a person develops moderate or severe bipolar depression and is already taking lithium, check their plasma lithium level. If it is inadequate, increase the dose of lithium; if it is at maximum level, add either fluoxetine combined with olanzapine or add quetiapine.

1.6.5

If a person develops moderate or severe bipolar depression and is already taking valproate, review their treatment including adherence and consider increasing the dose if tolerated but be aware of the increased risk of side effects at higher doses. Follow the recommendations in the section on how to use medication on using valproate. [2014, amended 2023]

1.6.6

If the maximum tolerated dose, or the top of the therapeutic range for valproate, has been reached and there is a limited response, add either of the following options, depending on the person's preference and previous response to treatment:

1.6.7

If the person does not wish to try adding fluoxetine combined with olanzapine or adding quetiapine, consider:

1.6.8

If there is no response to adding fluoxetine combined with olanzapine or adding quetiapine, consider stopping the additional medications and:

1.6.9

If a woman or girl of childbearing potential is already taking valproate, advise her to gradually stop the drug under medical supervision because of the risk of fetal malformations and adverse neurodevelopmental outcomes after any exposure in pregnancy . Follow the MHRA safety advice on the use of valproate. [2014]

1.6.10

Follow the recommendations on using antipsychotics in the section on how to use medication and be aware of the potential interactions between valproate and fluoxetine, lamotrigine and olanzapine. Follow the MHRA safety advice on the use of valproate. [2014, amended 2020]

1.6.11

Take into account toxicity in overdose when prescribing psychotropic medication during periods of high suicide risk. Assess the need to limit the quantity of medication supplied to reduce the risk to life if the person overdoses. [2014]

For a short explanation of why the recommendations were amended in 2023 and full details of the evidence see the evidence review for changes to valproate recommendations after revised MHRA safety advice.

Reviewing treatment for bipolar depression

1.6.12

Within 4 weeks of resolution of symptoms, discuss with the person, and their carers if appropriate, whether to continue psychological or pharmacological treatment for bipolar depression or start long‑term treatment (see the section on managing bipolar disorder in adults in the longer term in secondary care). Explain the potential benefits of long‑term treatment and the risks, including side effects of medication used for long‑term treatment. [2014]

1.6.13

If the person decides to continue psychological or pharmacological treatment for bipolar depression, offer it for a further 3 to 6 months, and then review. [2014]

1.7 Managing bipolar disorder in adults in the longer term in secondary care

Discussing long‑term treatment

1.7.1

After each episode of mania or bipolar depression, discuss with the person, and their carers if appropriate, managing their bipolar disorder in the longer term. Discussion should aim to help people understand that bipolar disorder is commonly a long‑term relapsing and remitting condition that needs self‑management and engagement with primary and secondary care professionals and involvement of carers. The discussion should cover:

Psychological interventions

1.7.2

Offer a family intervention to people with bipolar disorder who are living, or in close contact, with their family in line with recommendation 1.3.7.2 in NICE's guideline on psychosis and schizophrenia in adults. [2014]

1.7.3

Offer a structured psychological intervention (individual, group or family), which has been designed for bipolar disorder and has a published evidence-based manual describing how it should be delivered, to prevent relapse or for people who have some persisting symptoms between episodes of mania or bipolar depression. [2014]

1.7.4

Individual and group psychological interventions for bipolar disorder to prevent relapse should:

Pharmacological interventions

1.7.5

When planning long‑term pharmacological treatment to prevent relapse, take into account drugs that have been effective during episodes of mania or bipolar depression. Discuss with the person whether they prefer to continue this treatment or switch to lithium, and explain that lithium is the most effective long‑term treatment for bipolar disorder. [2014]

1.7.6

When considering long-term treatment, discuss with the person the possible benefits and risks of each drug for them, following the recommendations in the section on how to use medication. [2014, amended 2023]

1.7.7

Offer lithium as a first‑line, long‑term pharmacological treatment for bipolar disorder. [2014]

1.7.8

If lithium is ineffective, poorly tolerated, or is not suitable (for example, because the person does not agree to routine blood monitoring), consider an antipsychotic (for example asenapine, aripiprazole, olanzapine, quetiapine or risperidone). [2014, amended 2023]

1.7.9

If the first antipsychotic is poorly tolerated at any dose (including rapid weight gain) or ineffective at the maximum licensed dose, consider an alternative antipsychotic from the drugs listed in recommendation 1.7.8). [2014, amended 2023]

1.7.10

If an alternative antipsychotic is ineffective, consider a combination of valproate with either:

1.7.11

Do not start valproate for the first time in people (male or female) younger than 55 years, unless 2 specialists independently agree and document that there is no other effective and tolerated treatment, or there are compelling reasons that the reproductive risks do not apply. Ensure the pregnancy prevention programme is in place if valproate is used in women and girls of childbearing potential. Follow the MHRA safety advice on the use of valproate.

In September 2014 semi-sodium valproate had a UK marketing authorisation for this indication in people who have had mania that has responded to treatment with semi-sodium valproate; it was an off-label use of sodium valproate, although its use was common in UK clinical practice. See NICE's information on prescribing medicines. [2014, amended 2023]

1.7.12

If a woman or girl of childbearing potential is already taking valproate, advise her to gradually stop the drug under medical supervision because of the risk of fetal malformations and adverse neurodevelopmental outcomes after any exposure in pregnancy . Follow the MHRA safety advice on the use of valproate.

In September 2014 semi-sodium valproate had a UK marketing authorisation for this indication in people who have had mania that has responded to treatment with semi-sodium valproate; it was an off-label use of sodium valproate, although its use was common in UK clinical practice. See NICE's information on prescribing medicines. [2014, amended 2020]

1.7.13

If stopping long‑term pharmacological treatment:

1.7.14

Continue monitoring symptoms, mood and mental state for 2 years after medication has stopped entirely. This may be undertaken in primary care (see recommendation 1.9.3). [2014]

For a short explanation of why the recommendations were amended in 2023 and full details of the evidence see the evidence review for changes to valproate recommendations after revised MHRA safety advice.

1.8 Monitoring physical health in secondary care

1.8.1

Healthcare professionals in secondary care should ensure, as part of the care programme approach, that people with bipolar disorder receive physical healthcare from primary care as described in recommendations 1.2.10 to 1.2.14 after responsibility for monitoring has been transferred from secondary care. [2014]

1.8.2

People with bipolar disorder, especially those taking antipsychotics and long‑term medication, should be offered a combined healthy eating and physical activity programme by their mental healthcare provider. [2014]

1.8.3

If a person has rapid or excessive weight gain, abnormal lipid levels or problems with blood glucose management, take into account the effects of medication, mental state, other physical health and lifestyle factors in the development of these problems. [2014]

1.8.4

Routinely monitor weight and cardiovascular and metabolic indicators of morbidity in people with bipolar disorder. These should be audited in the annual team report. [2014]

1.8.5

Trusts should ensure that they take account of relevant guidelines on the monitoring and treatment of cardiovascular and metabolic disease in people with bipolar disorder through board‑level performance indicators. [2014]

1.9 Promoting recovery and return to primary care

Continuing treatment in secondary care

1.9.1

Continue treatment and care in an early intervention in psychosis service, a specialist bipolar disorder service or a specialist integrated community‑based team. Share physical health monitoring with primary care as outlined in the sections on physical health and monitoring physical health in primary care. [2014]

1.9.2

Consider intensive case management for people with bipolar disorder who are likely to disengage from treatment or services. [2014]

Return to primary care

1.9.3

Offer people with bipolar disorder whose symptoms have responded effectively to treatment and remain stable the option to return to primary care for further management. If they wish to do this, record it in their notes and coordinate transfer of responsibilities through the care programme approach. [2014]

1.9.4

When making transfer arrangements for a return to primary care, agree a care plan with the person, which includes:

1.9.5

Encourage and support the person to visit their GP and discuss the care plan before discharge and transfer. [2014]

Employment, education and occupational activities

1.9.6

Offer supported employment programmes to people with bipolar disorder in primary or secondary care who wish to find or return to work. Consider other occupational or educational activities, including pre‑vocational training, for people who are unable to work or unsuccessful in finding employment. [2014]

1.10 How to use medication

1.10.1

When using any psychotropic medication for bipolar disorder ensure that:

1.10.2

Discuss the use of alcohol, tobacco, prescription and non‑prescription medication and illicit drugs with the person, and their carer if appropriate. Explain the possible interference of these substances with the therapeutic effects of prescribed medication and psychological interventions. [2014]

1.10.3

When offering psychotropic medication to older people, take into account its impact on cognitive functioning in older people and:

1.10.4

Do not offer gabapentin or topiramate to treat bipolar disorder. [2014]

Using antipsychotic medication

Starting antipsychotic medication
1.10.5

Before starting antipsychotic medication, measure and record the person's:

1.10.6

Before starting antipsychotic medication, offer the person an electrocardiogram (ECG) if:

1.10.7

Treatment with antipsychotic medication should be considered an explicit individual therapeutic trial. Carry out the following:

Monitoring antipsychotic medication
1.10.8

Monitor and record the following during dose titration and then regularly and systematically throughout treatment:

1.10.9

The secondary care team should maintain responsibility for monitoring the efficacy and tolerability of antipsychotic medication for at least the first 12 months or until the person's condition has stabilised, whichever is longer. Thereafter, the responsibility for this monitoring may be transferred to primary care under shared‑care arrangements. [2014]

1.10.10

If out‑of‑range test results are reported at any stage of treatment, the healthcare professional who ordered the tests should ensure that the person is offered further investigations and treatment as needed. [2014]

1.10.11

'As required' (p.r.n.) prescriptions of antipsychotic medication should be made as described in recommendation 1.10.7. Review clinical indications, frequency of administration, therapeutic benefits and side effects each week or more often if needed. Ensure that p.r.n. prescriptions have not unintentionally led to a total antipsychotic dosage above the maximum specified in the BNF or SPC. [2014]

1.10.12

Do not start regular combined antipsychotic medication, except for short periods (for example, when changing medication). [2014]

Stopping antipsychotic drugs
1.10.13

If stopping an antipsychotic drug, reduce the dose gradually over at least 4 weeks to minimise the risk of relapse. [2014]

Using lithium

Starting lithium
1.10.14

When starting lithium:

1.10.15

Measure plasma lithium levels 1 week after starting lithium and 1 week after every dose change, and weekly until the levels are stable. Aim to maintain plasma lithium level between 0.6 and 0.8 mmol per litre in people being prescribed lithium for the first time. [2014]

1.10.16

Consider maintaining plasma lithium levels at 0.8 to 1.0 mmol per litre for a trial period of at least 6 months for people who:

1.10.17

Advise people taking lithium to:

1.10.18

Warn people taking lithium not to take over‑the‑counter non‑steroidal anti‑inflammatory drugs and avoid prescribing these drugs for people with bipolar disorder if possible; if they are prescribed, this should be on a regular (not p.r.n.) basis and the person should be monitored monthly until a stable lithium level is reached and then every 3 months. [2014]

Monitoring lithium
1.10.19

Measure the person's plasma lithium level every 3 months for the first year. [2014]

1.10.20

After the first year, measure plasma lithium levels every 6 months, or every 3 months for people in any of the following groups:

1.10.21

Measure the person's weight or BMI and arrange tests for urea and electrolytes including calcium, estimated glomerular filtration rate (eGFR) and thyroid function every 6 months, and more often if there is evidence of impaired renal or thyroid function, raised calcium levels or an increase in mood symptoms that might be related to impaired thyroid function. [2014]

1.10.22

Monitor lithium dose and plasma lithium levels more frequently if urea levels and creatinine levels become elevated, or eGFR falls over 2 or more tests, and assess the rate of deterioration of renal function. For further information see NICE's guidelines on chronic kidney disease and acute kidney injury. [2014]

1.10.23

When discussing whether to continue lithium, take into account clinical efficacy, other risk factors for renal impairment and cardiovascular disease, and degree of renal impairment; if needed seek advice from a renal specialist and a clinician with expertise in managing bipolar disorder. [2014]

1.10.24

Monitor the person at every appointment for symptoms of neurotoxicity, including paraesthesia, ataxia, tremor and cognitive impairment, which can occur at therapeutic levels of lithium. [2014]

Stopping lithium
1.10.25

If stopping lithium, reduce the dose gradually over at least 4 weeks, and preferably up to 3 months, even if the person has started taking another antimanic drug. [2014]

1.10.26

During dose reduction and for 3 months after lithium treatment is stopped, monitor the person closely for early signs of mania and depression. [2014]

Using valproate

1.10.27

Do not start valproate for the first time in people (male or female) younger than 55 years, unless 2 specialists independently agree and document that there is no other effective and tolerated treatment, or there are compelling reasons that the reproductive risks do not apply. Ensure the pregnancy prevention programme is in place if valproate is used in women and girls of childbearing potential. Follow the MHRA safety advice on the use of valproate. [2014, amended 2023]

1.10.28

If a woman or girl of childbearing potential is already taking valproate, advise her to gradually stop the drug under medical supervision because of the risk of fetal malformations and adverse neurodevelopmental outcomes after any exposure in pregnancy . Follow the MHRA safety advice on the use of valproate. [2014, amended 2020]

Starting valproate
1.10.29

When starting valproate, measure the person's weight or BMI and carry out a full blood count and liver function tests. [2014]

1.10.30

Advise people taking valproate, and their carers, how to recognise the signs and symptoms of blood and liver disorders and to seek immediate medical help if any of these develop. Stop valproate immediately if abnormal liver function or blood dyscrasia is detected.

Although the absolute values of hepatic enzymes are a poor indicator of the extent of hepatic damage, it is generally accepted that if these are persistently elevated to over 3 times the upper normal limit, continuing to rise or accompanied by clinical symptoms, the suspected drug should be withdrawn. Raised hepatic enzymes of any magnitude accompanied by reduced albumin or impaired clotting suggest severe liver disease. [2014]

1.10.31

When prescribing valproate, be aware of its interactions with other anticonvulsants (particularly carbamazepine and lamotrigine) and with olanzapine and smoking. [2014]

Monitoring valproate
1.10.32

Do not routinely measure plasma valproate levels unless there is evidence of ineffectiveness, poor adherence or toxicity. [2014]

1.10.33

Measure the person's weight or BMI and carry out liver function tests and a full blood count again after 6 months of treatment with valproate and repeat annually. [2014]

1.10.34

Monitor sedation, tremor and gait disturbance carefully in older people. [2014]

Stopping valproate
1.10.35

If stopping valproate, to change to an alternative medication, reduce the dose gradually over at least 4 weeks to minimise the risk of relapse. [2014]

Using lamotrigine

Starting lamotrigine
1.10.36

When starting lamotrigine:

1.10.37

Advise people taking lamotrigine to:

Monitoring lamotrigine
1.10.38

Do not routinely measure plasma lamotrigine levels unless there is evidence of ineffectiveness, poor adherence or toxicity. [2014]

Stopping lamotrigine
1.10.39

If stopping lamotrigine, reduce the dose gradually over at least 4 weeks to minimise the risk of relapse. [2014]

1.11 Recognising, diagnosing and managing bipolar disorder in children and young people

Recognition and referral

1.11.1

Do not use questionnaires in primary care to identify bipolar disorder in children or young people. [2014]

1.11.2

If bipolar disorder is suspected in primary care in children or young people aged under 14 years, refer them to child and adolescent mental health services (CAMHS). [2014]

1.11.3

If bipolar disorder is suspected in primary care in young people aged 14 years or over, refer them to a specialist early intervention in psychosis service or a CAMHS team with expertise in the assessment and management of bipolar disorder in line with the recommendations in this guideline. The service should be multidisciplinary and have:

Diagnosis and assessment
1.11.4

Diagnosis of bipolar disorder in children or young people should be made only after a period of intensive, prospective longitudinal monitoring by a healthcare professional or multidisciplinary team trained and experienced in the assessment, diagnosis and management of bipolar disorder in children and young people, and in collaboration with the child or young person's parents or carers.

1.11.5

When diagnosing bipolar disorder in children or young people take account of the following:

1.11.6

Do not make a diagnosis of bipolar disorder in children or young people on the basis of depression with a family history of bipolar disorder but follow them up. [2014]

1.11.7

When assessing suspected bipolar disorder in children or young people, follow recommendations 1.3.2 to 1.3.4 for adults, but involve parents or carers routinely and take into account the child or young person's educational and social functioning. [2014]

Management in young people

1.11.8

When offering treatment to young people with bipolar disorder, take into account their cognitive ability, emotional maturity, developmental level, their capacity to consent to treatment, the severity of their bipolar disorder and risk of suicide or self‑harm or any other risk outlined in recommendation 1.3.5. [2014]

Mania
1.11.9

To treat mania or hypomania in young people see NICE's technology appraisal guidance on aripiprazole for treating moderate to severe manic episodes in adolescents with bipolar I disorder and also consider the recommendations for adults in the section on managing mania or hypomania in adults in secondary care. Refer to the BNF for children to modify drug treatments, be aware of the increased potential for a range of side effects, and do not routinely continue antipsychotic treatment for longer than 12 weeks.

In September 2014 aripiprazole had a UK marketing authorisation for up to 12 weeks of treatment for moderate to severe manic episodes in bipolar I disorder in young people aged 13 and older.

In September 2014, this was an off-label use of olanzapine, risperidone, haloperidol, quetiapine, lamotrigine, lithium and valproate for children and young people. See NICE's information on prescribing medicines. [2014]

1.11.10

Do not offer valproate to children unless there is no other effective and tolerated treatment. Follow the MHRA safety advice on the use of valproate. [2014, amended 2023]

Bipolar depression
1.11.11

Offer a structured psychological intervention (individual cognitive behavioural therapy or interpersonal therapy) to young people with bipolar depression. The intervention should be of at least 3 months' duration and have a published evidence-based manual describing how it should be delivered. [2014]

1.11.12

If after 4 to 6 weeks there is no or a limited response to cognitive behavioural therapy or interpersonal therapy, carry out a multidisciplinary review and consider an alternative individual or family psychological intervention. [2014]

1.11.13

If there is a risk of suicide or self‑harm or any other risk outlined in recommendation 1.3.5, carry out an urgent review and develop a risk management plan as outlined in recommendation 1.4.1. [2014]

1.11.14

After the multidisciplinary review, if there are coexisting factors such as comorbid conditions, persisting psychosocial risk factors such as family discord, or parental mental ill‑health, consider:

1.11.15

If the young person's bipolar depression is moderate to severe, consider a pharmacological intervention in addition to a psychological intervention. Follow the recommendations for pharmacological interventions for adults in the section on managing bipolar depression in adults in secondary care, but do not routinely continue antipsychotic treatment for longer than 12 weeks. At 12 weeks, carry out a full multidisciplinary review of mental and physical health, and consider further management of depression or long‑term management.

In September 2014, this was an off-label use of olanzapine, quetiapine and lamotrigine for children and young people. See NICE's information on prescribing medicines. [2014]

Long‑term management
1.11.16

After the multidisciplinary review, consider a structured individual or family psychological intervention for managing bipolar disorder in young people in the longer term. [2014]

Terms used in this guideline

Carer

A person who provides unpaid support to a partner, family member, friend or neighbour who is ill, struggling or disabled.

Children

People aged 12 years and under.

Depression

The severity of bipolar depression is defined as follows:

Evidence‑based manual

A manual based on at least 1 randomised controlled trial published in a peer‑reviewed journal showing effectiveness of the intervention in reducing depression symptoms in bipolar depression or, when used as long‑term treatment, reducing relapse in people with bipolar disorder.

Older people

People aged 65 years and over.

Young people

People aged 13 to 17 years.

Valproate

Refers to 3 formulations of valproate available in the UK: sodium valproate, valproic acid and semi‑sodium valproate. At the time of publication (September 2014), sodium valproate and valproic acid had UK marketing authorisation for the treatment of epilepsy. Semi‑sodium valproate had a UK marketing authorisation for the treatment of acute mania and for continuation treatment in people who have had mania that has responded to treatment with semi‑sodium valproate. Both semi‑sodium and sodium valproate are metabolised to valproic acid (also known as valproate), which is the pharmacologically active component. Follow the MHRA safety advice on the use of valproate.
