1 Introduction
1.1 This Practice Guidance Note (PGN) provides step by step guidance and support for those healthcare professionals within Cumbria Northumberland, Tyne and Wear NHS Foundation Trust (the Trust/CNTW) wishing to prescribe valproate for either epilepsy/seizure control, mania or mood-stabilisation.
1.2 Valproate is available in the UK in three distinct forms; sodium valproate and
valproic acid (licensed for treatment of epilepsy) and semi-sodium valproate (licensed for treatment of acute mania).
1.3 Valproate (as sodium valproate) is unlicensed for use as a mood-stabiliser, but is
widely used in the UK for this indication. Further guidance on the use of unlicensed medications can be found in section 9, UHM-PGN-02 Prescribing Medicines.
1.4 To protect public health, the Medicines and Healthcare products Regulatory Agency
(MHRA) has changed the licence for valproate medicines (Epilim, Depakote and generic brands):
Valproate must no longer be prescribed to women or girls of childbearing potential unless they are on the Pregnancy Prevention Programme (PPP) and only if other treatments are ineffective or not tolerated, as judged by an experienced specialist.
These conditions also concern women who are not currently sexually active unless the prescriber considers that there are compelling reasons to indicate that there is no risk of pregnancy.
Use of valproate in pregnancy is contraindicated for migraine and bipolar disorder and must only be considered for epilepsy if there is no suitable alternative treatment.
Specialists (consultant psychiatrists and neurologists) must book in review appointments at least annually with women and girls under the PPP and re-evaluate treatment as necessary.
Further requirements under the PPP can be found at section 3 Congenital malformation and development disorders.
2 Prescribing valproate
2.1 Baseline monitoring prior to commencing valproate
2.1.1 The following monitoring should be carried out and recorded in the Core Physical
Health Monitoring Record on RiO:
Allergies
Baseline Full Blood Count (FBC) plus bleeding time and coagulation tests
Liver Function Tests (LFTs) Weight/Body Mass Index/waist circumference where possible (an individual
![Page 4: (incorporating the Pregnancy Prevention Programme)- V02 ... · 2.6 Valproate shared care guidelines 1 2 2 2 3 3 3 Congenital malformations and development disorders: ... it with their](https://reader034.vdocuments.net/reader034/viewer/2022052015/602ca17a8441a22a860802c6/html5/thumbnails/4.jpg)

should be referred to a dietitian if they have comorbidities such as diabetes, heart disease or a BMI of 35 or above)
For women of reproductive age, a plasma pregnancy test should be carried out prior to starting valproate (see Section 3, Congenital malformations and developmental disorders)
Side effect baseline (using the VSERS monitoring tool, Appendix 6)
2.2 On-going valproate monitoring
2.2.1 Valproate Summary of Product Characteristics (SPC) recommend frequent
monitoring of LFTs during the first 6 months of therapy, particularly for those at most risk (e.g. young children <3 years) or those with a prior history of liver disease. As with most antiepileptic drugs, increased liver enzymes are common, particularly at the beginning of therapy; they are also often transient. In any event weight/BMI, LFTs and FBCs (plus bleeding time and coagulation tests) should be repeated annually.
2.2.2 Amongst usual investigations, tests which reflect protein synthesis, particularly prothrombin rate, are most relevant. Confirmation of an abnormally low prothrombin rate, particularly in association with other biological abnormalities (significant decrease in fibrinogen and coagulation factors; increased bilirubin level and raised transaminases) requires cessation of valproate therapy.
2.2.3 Following each valproate review, it is good practice to make an entry in the progress
notes stating that the appropriate RIO documents have been updated. 2.2.4 There should be regular (for example at CPA review) monitoring of family planning
including the use of highly effective contraception, risks to pregnancy and plans to conceive a pregnancy. All healthcare staff must contact the specialist immediately if they suspect problems with contraception cover, or that the patient may be pregnant.
2.2.5 Women and girls should be reminded not to stop taking valproate without first discussing
it with their doctor. 2.3 Therapeutic Drug Monitoring of Valproate levels
2.3.1 The pharmacokinetics of valproate is complex, following a three compartment
model and showing protein-binding saturation. R e g u l a r p lasma level monitoring is generally considered of little use, other than where there is evidence of ineffectiveness or for confirming adherence to therapy. Many side effects of valproate appear to be dose-related (peak plasma-level related) and increase in frequency and severity when plasma levels are high; more frequent monitoring of plasma levels might be considered where problems exist despite good clinical management. Further guidance is available from pharmacy.
2.4 Side-effect monitoring
2.4.1 Patients should be asked if they are experiencing any side effects related to valproate at
each appointment. A formal assessment of side effects should be carried out annually. The Valproate Side Effect Rating Scale (VSERS) check list may be used for this purpose (Appendix 6).
![Page 5: (incorporating the Pregnancy Prevention Programme)- V02 ... · 2.6 Valproate shared care guidelines 1 2 2 2 3 3 3 Congenital malformations and development disorders: ... it with their](https://reader034.vdocuments.net/reader034/viewer/2022052015/602ca17a8441a22a860802c6/html5/thumbnails/5.jpg)

2.4.2 Patients/carers should be aware of those symptoms that may indicate serious liver
damage and should be advised to seek immediate medical attention if they develop. The following may precede jaundice:
Non-specific symptoms, usually of sudden onset, such as:
o Asthenia (abnormal physical weakness or lack of strength) o Malaise o Anorexia o Lethargy (lack of energy or vigour) o Oedema o Drowsiness o Patients experiencing nausea, vomiting or acute abdominal pain should
have a prompt medical evaluation (including measurement of serum amylase) to exclude pancreatitis.
In patients with epilepsy; recurrence of seizures
2.4.3 Suspected adverse drug reactions of valproate should be reported via the Yellow
Card reporting scheme https://yellowcard.mhra.gov.uk/the-yellow-card-scheme/
2.5 Drug-drug interactions 2.5.1 Prescribers must have a system for checking, identifying and acting on any concurrent
medications that may interact with valproate. It is good practice to check the BNF for interaction potential when a new medicine is commenced for a patient stabilised on valproate.
2.5.2 Valproate may potentiate the effect of other psychotropics such as antipsychotics, monoamine oxidase inhibitors, antidepressants and benzodiazepines; therefore, clinical monitoring is advised and the dosage of other psychotropics should be adjusted when appropriate.
2.5.3 In particular, a clinical study has suggested that adding olanzapine to valproate therapy
may significantly increase the risk of certain adverse events associated with olanzapine e.g. neutropenia, tremor, dry mouth, increased appetite and weight gain, speech disorder and somnolence. The two drugs may also have an additive detrimental effect on LFTs.
2.5.4 Prescribers should also be aware of valproate’s interaction with other
anticonvulsants (particularly carbamazepine and lamotrigine) and smoking. Further guidance on the effects of smoking can be found in Smoking Cessation and Psychotropic Drug Interactions V03-Iss2- Sep 17- HWB-PGN-02.1 - CNTW(O)13 (excluding clozapine)
2.6 Valproate shared care guidelines
2.6.1 The shared care status of valproate is ‘green’ in all CNTW localities. ‘Green’ drugs
are appropriate for prescribing by GPs
![Page 6: (incorporating the Pregnancy Prevention Programme)- V02 ... · 2.6 Valproate shared care guidelines 1 2 2 2 3 3 3 Congenital malformations and development disorders: ... it with their](https://reader034.vdocuments.net/reader034/viewer/2022052015/602ca17a8441a22a860802c6/html5/thumbnails/6.jpg)

3 Congenital malformations and development disorders
3.1 In utero exposure to valproate is associated with serious adverse effects for the
developing child, including:
Congenital malformations. Affecting approximately 10% of cases, these
include; neural tube defects (spina bifida, anencephaly), facial dysmorphia and cardiac malformations.
Developmental disorders. Affecting approximately 30-40% of cases, these can
include an increased risk of autistic spectrum disorder (approximately three-fold increase in risk), childhood autism (approximately five-fold increase in risk) and delays in early development. There is evidence that children exposed to valproate in utero will go on to have a lower IQ than children exposed to other antiepileptic drugs.
3.2 Prescriber checklist and annual review
When valproate is prescribed for any female patient between menarche and
menopause, the Valproate in women of childbearing potential: Prescribers Checklist (Appendix 1) must be completed. The checklist should be completed for those who have already been stabilised on the drug and those patients newly started on valproate. Menarche is the time in a girl's life when menstruation first begins, the average age of menarche in the UK is around 13 years.
Additionally, the Annual Risk Acknowledgment Form (Appendix 4) must be completed and signed, with a copy provided to the patient parent/caregiver/responsible person and GP on each occasion.
The completed Prescribers Checklist and Annual Risk Acknowledgment Form must be
scanned and uploaded to the patient’s medical record as per guidance in Records-Keeping Standards PGN - V03 - Issue4 - May 18- RM-PGN-02 - CNTW(O)09
For female patients who have not yet reached menarche, or where the absence of risk
of pregnancy is permanent, the requirements of the PPP do not apply. It is imperative however that this decision is recorded using the Annual Risk Acknowledgement Form (Appendix 4) and communicated to the GP as above.
Where the absence of risk of pregnancy is subject to change (e.g. the patient is pre-menarchal) annual reviews must be undertaken. The patient or patient’s family/carers should be asked to contact the specialist immediately if the situation changes to allow the annual review to be brought forward.
The Prescribers Checklist (Appendix 1) combines the MHRA’s checklist
requirements along with CNTW-specific requirements.
Specialists must book in review appointments at least annually with women and girls under the PPP and re-evaluate treatment as necessary; notifying the patients GP.

Smaller pack sizes will be produced by manufacturers to encourage monthly prescribing.
When valproate is prescribed for a female patient of childbearing potential, it is the
responsibility of the prescriber to ensure she is provided with a Valproate Patient’s Card (Appendix 5), unless she confirms that she already has one. The prescriber must encourage the patient to read the card and enter her name and current date in the spaces provided.
A pan-college guidance document has been produced that seeks to provide practical
information and guidance, and sources of further support, for clinicians involved with valproate: it gathers data, where available, on best practice and summarises consensus opinion from seventeen national bodies across the UK. This document address women who might refuse to participate in the PPP, capacity and consent issues and those patients with intellectual difficulties. The document is available here
3.2.1 Risk assessment
Prescribers must read the Valproate information booklet for healthcare professionals (Healthcare Professional’s Booklet, Appendix 2).
Prescribers must always carefully balance the benefits of valproate treatment against the risks. Valproate should only be initiated or continued when other treatment options have been ineffective or have not been tolerated and pregnancy is excluded by means of a negative plasma pregnancy test.
3.2.2 Capacity assessment
Prescribers must ensure that the patient’s capacity to consent to treatment has been assessed and has been documented in their medical record (CNTW(C)05 Consent to Examination or Treatment Policy).
Specific guidance in relation to children, young people, adults who lack capacity and Best Interest decision making can be found in CNTW(C)05 Consent to Examination or Treatment Policy.
3.2.3 Information provision
Ensure the patient/parent/caregiver/responsible person understands the nature of the
PPP and requirement for strict adherence to allow continued prescribing of valproate.
It is the responsibility of the prescriber to ensure that the patient/parent/caregiver/responsible person is provided with all necessary information about the risk posed by valproate use during pregnancy. The MHRA recommend that this includes understanding the 30–40% risk of neurodevelopmental disorders and 10% risk of birth defects.
Prescribers must ensure that the patient/parent/caregiver/responsible person has
been provided with a copy of the Valproate information booklet for patients (Patient’s
![Page 8: (incorporating the Pregnancy Prevention Programme)- V02 ... · 2.6 Valproate shared care guidelines 1 2 2 2 3 3 3 Congenital malformations and development disorders: ... it with their](https://reader034.vdocuments.net/reader034/viewer/2022052015/602ca17a8441a22a860802c6/html5/thumbnails/8.jpg)

Guide, Appendix 3).
Prescribers must ensure that the patient/parent/caregiver/responsible person has been informed about the need for highly effective contraception and is prescribed such contraception or referred immediately to a specialist as required.
Prescribers must ensure that the patient/parent/caregiver/responsible person has
been informed to promptly contact them if she is planning a pregnancy or becomes pregnant. Specialists should see the patient urgently (within days) if referred back from healthcare colleagues due to concerns relating to effective contraception, unplanned pregnancy or plans for pregnancy.
The above information should be repeated at regular intervals, for example CPA reviews.
3.2.4 Obtaining consent
Prescribers should document capacity to consent to treatment with valproate,
specifically in women of reproductive age taking into account the potential risks in pregnancy.
Prescribers should ask the patient/carer/parent or responsible person to complete the
Annual Risk Acknowledgment Form – Part A at each annual review (Appendix 4)
The completed consent form must be scanned and uploaded to the patient’s medical record as per guidance in Records-Keeping Standards PGN - V03 - Issue4 - May 18- RM-PGN-02 - CNTW(O)09
3.2.5 Risk reduction strategies
Prescribers must ensure that a patient has had a negative plasma pregnancy test prior to starting valproate and must advise patients on the need for highly effective contraception.
Where there are reasons to suggest lack of compliance with contraception or reduced
effectiveness, the specialist should perform pregnancy testing as required
In the event that any healthcare staff suspect problems with contraception cover, or that
the patient may be pregnant they must contact the specialist immediately.
If a woman is planning to become pregnant, or becomes pregnant on valproate she must
be immediately referred to a specialist to consider alternative treatment options. The prescriber must make every effort to switch the patient to another treatment; where this is not possible the patient should be referred for counselling about the risks. Switching should be achieved prior to conception and before contraception is discontinued. Clear documentation in RiO of the risk vs. benefit in these circumstances is paramount. Further guidance can be found in the RCPsych Position Statement PS04/18 Withdrawal of, and alternatives to, valproate-containing medicines in girls and women of childbearing potential who have a psychiatric illness.
It is recommended that pregnant women taking antiepileptic drugs in general, and valproate in particular, are enrolled in the UK Epilepsy and Pregnancy Register (http://www.epilepsyandpregnancy.co.uk). This should be done as early as possible in
![Page 9: (incorporating the Pregnancy Prevention Programme)- V02 ... · 2.6 Valproate shared care guidelines 1 2 2 2 3 3 3 Congenital malformations and development disorders: ... it with their](https://reader034.vdocuments.net/reader034/viewer/2022052015/602ca17a8441a22a860802c6/html5/thumbnails/9.jpg)

the pregnancy, before the outcome is known.
If, despite the known risks of valproate in pregnancy and after careful consideration of alternative treatment, in exceptional circumstances a pregnant woman must receive valproate for epilepsy:
o There is no dose threshold considered to be without any risk. However, the risk of birth defects and developmental disorders is higher at greater doses
o Use the lowest effective dose and divide the daily dose of valproate into several small doses to be taken throughout the day
o Prescribers must ensure that the patient is prescribed folic acid
The use of a prolonged release formulation may be preferable to other treatment
formulations in order to avoid high peak plasma concentrations
All patients with a valproate exposed pregnancy and their partners should be referred
to a specialist experienced in prenatal medicine.
3.2.6 H i g h l y Effective contraception
Highly effective contraception is considered for regulatory purposes to be those user independent methods such as the long acting reversible contraceptives (LARC), copper intrauterine device (Cu-IUD), levonorgestrel intrauterine system (LNG-IUS) and progestogen only implant (IMP) and female sterilisation, all of which have a failure rate of less than 1% with typical use. The progesterone-only injectable is reported to have a typical use failure rate of 6 pregnancies per 100 women per year of typical use compared to 0.2 pregnancies with perfect use (thought to be due to the 3 monthly requirement for re-injection and lack of compliance with this).
User dependent methods such as the condom, cap, diaphragm, combined oral contraceptive pill (COC) or progestogen-only contraceptive pill (POP) and fertility awareness based methods are not considered highly effective since the typical use incorporates user failure risks. If a user-independent form is not used, two complementary forms of contraception including a barrier method should be used and regular pregnancy testing considered.
Prescribers must discuss the following topics with patients/parent/caregiver/responsible person before valproate is first prescribed :
o Assess the most appropriate timing to provide advice on effective
contraception methods and refer your patient to a specialist if needed.
o Discuss highly effective methods of contraception that best suits the patient’s
individual needs and lifestyle, so making it more likely that they will use contraception and use it effectively.
o Consider NICE Guidance recommending long-acting contraception (which is of
particular benefit where the risks of an unplanned pregnancy are high).
o Ensure your patient understands the importance of using contraception throughout the duration of treatment to avoid unplanned pregnancy
![Page 10: (incorporating the Pregnancy Prevention Programme)- V02 ... · 2.6 Valproate shared care guidelines 1 2 2 2 3 3 3 Congenital malformations and development disorders: ... it with their](https://reader034.vdocuments.net/reader034/viewer/2022052015/602ca17a8441a22a860802c6/html5/thumbnails/10.jpg)

9 Cumbria Northumberland, Tyne and Wear NHS Foundation Trust PPT–PGN–25- Safe Prescribing of Valproate V02-Issue 3-Nov 19 Part of CNTW(C)38 Pharmacological Therapy Policy
o Advise your patient to contact you immediately if she thinks she might be
pregnant or becomes pregnant.
Further guidance on the full range of effective contraceptive methods to be offered can be obtained from NICE (Public Health guideline PH51: Contraceptives services for under 25s) and the Faculty of Sexual and Reproductive Healthcare guidelines (https://www.fsrh.org/standards-and-guidance/current-clinical-guidance/).
Although specific data are limited, drug-drug interactions between valproate and
contraceptive hormones are unlikely to result in any significant reduction in efficacy of the combined hormonal contraceptive (Baxter, 2017). However, valproate is metabolised by glucuronide conjugation, and therefore its levels may be reduced due to induction of glucuronosyltransferases by ethinylestradiol. (Baxter, 2017; FSRH, 2017)
3.3 Patients who refuse information
Occasionally patients may not wish to receive information when valproate is
prescribed, or they may not currently be receptive to such information. In these circumstances, serious consideration should be given to delaying valproate treatment until the patient is willing and able to accept information about the risks posed by the drug.
However, if the initiation of valproate is considered to be absolutely necessary, then the
prescriber must complete the following actions:
O Consider the need for highly effective contraception throughout treatment with valproate
o Complete as much of the Valproate in women of childbearing potential: Prescribers Checklist (Appendix 1) as possible at the current time, and add this to the patient’s medical record.
o Use the ‘Additional comments’ section of the checklist to make a note of the
information that the patient is currently refusing. o Ensure that another attempt to provide the information to the patient is made at the
earliest possible opportunity. o Make an entry in the patient’s medical record stating why it was not possible to
complete the full checklist, and why it was considered necessary to prescribe the medication despite this.
3.4 Sharing information
A copy of the completed Prescribers Checklist (Appendix 1) and Annua l R i sk Ackno wled gmen t Fo rm (Appendix 4) must be forwarded to the patient’s GP along with their discharge summary or clinic letter.
![Page 11: (incorporating the Pregnancy Prevention Programme)- V02 ... · 2.6 Valproate shared care guidelines 1 2 2 2 3 3 3 Congenital malformations and development disorders: ... it with their](https://reader034.vdocuments.net/reader034/viewer/2022052015/602ca17a8441a22a860802c6/html5/thumbnails/11.jpg)

10 Cumbria Northumberland, Tyne and Wear NHS Foundation Trust PPT–PGN–25- Safe Prescribing of Valproate V02-Issue 3-Nov 19 Part of CNTW(C)38 Pharmacological Therapy Policy
A copy of the Prescribers Checklist and Annual Risk Acknowledgment Form must be given to the patient/parent/caregiver/responsible person
The GP should be asked to remind the patient about valproate’s adverse effects at
every consultation in which medication is discussed and review contraception/pregnancy plans.
3.5 Monitoring and follow-up
At all routine treatment reviews, prescribers must ensure that the benefits of
valproate continue to outweigh the risks.
For inpatients, the Valproate in women of childbearing potential: Prescribers Checklist (Appendix 1) must be completed when:
o Valproate is first prescribed and for any newly admitted patients who take the
medication. The risks should be reemphasised to the patient when they first go on
leave, and when they are discharged.
o The Annual Risk Acknowledgment Form (Appendix 4) must be completed for any newly
admitted patient who takes valproate, unless it can be proven that this has already
been completed within the preceding twelve months. Where a form has already been
completed, the annual review date must be scheduled.
For outpatients, the Prescribers Checklist (Appendix 1) must be completed when valproate is
first prescribed and then at least once every 6 months. The Annual Risk Acknowledgment Form
(Appendix 4) is to be completed annually
4 Dispensing valproate
4.1 When valproate is dispensed by a CNTW pharmacy for a female patient of childbearing potential, it is the responsibility of pharmacy staff to ensure she is provided with a Valproate Patient’s Card (Appendix 5), unless she confirms that she already has one.
4.2 Pharmacy staff must encourage the patient to read the card and enter her name and
current date in the spaces provided. 4.3 Pharmacy to ensure that valproate medicines are dispensed in whole packs
wherever possible to ensure warning labels and/or stickers are always visible. Valproate medicines will be available with a detachable patient card from December 2018.
4.4 If the medication is ‘packed down’ from original containers during the dispensing
process, the pharmacy will ensure that a sticker is added and the following warning is added to the regular dispensing label:
‘Warning for women and girls: this medicines can seriously harm an unborn baby, always use effective contraception during treatment, if you are thinking about becoming pregnant, or you become pregnant, talk to your doctor
![Page 12: (incorporating the Pregnancy Prevention Programme)- V02 ... · 2.6 Valproate shared care guidelines 1 2 2 2 3 3 3 Congenital malformations and development disorders: ... it with their](https://reader034.vdocuments.net/reader034/viewer/2022052015/602ca17a8441a22a860802c6/html5/thumbnails/12.jpg)

straight away.’
4.5 Where repackaging cannot be avoided pharmacy will always provide a copy of the
package insert
4.6 Pharmacy staff should discuss the risk of pregnancy with female patients each time
valproate medicines are dispensed and ensure they have a copy of the Patient Guide.
Further, pharmacy staff should ensure the patient has seen their GP or specialist to
discuss their treatment (reminding them of the need for an annual specialist review) and
the need for highly effective contraception.
4.7 If a women or girl of childbearing age reports that they are not taking effective
contraception, pharmacists should advise her to contact her GP or specialist for an urgent
follow-up (contact the GP or specialist directly if necessary)
