Date approved: June 2016 Review date: May 2019 Version: 201705 1 SHARED CARE PRESCRIBING GUIDELINE Melatonin for persistent sleep disorders in school age children with neurodevelopmental disabilities NOTES to the GP The expectation is that these guidelines should provide sufficient information to enable GPs to be confident to take clinical and legal responsibility for prescribing this drug. The questions below will help you confirm this: Is the patient’s condition predictable or stable? Do you have the relevant knowledge, skills and access to equipment to allow you to monitor treatment as indicated in this shared care prescribing guideline? Have you been provided with relevant clinical details including monitoring data? If you can answer YES to all these questions (after reading this shared care guideline), then it is appropriate for you to accept prescribing responsibility. Prescribe only 28 days at a time with a review date of every 6 months. If the answer is NO to any of these questions, you should not accept prescribing responsibility. You should write to the consultant within 14 days, outlining your reasons for NOT prescribing. If you do not have the confidence to prescribe, we suggest you discuss this with your local Trust/specialist service, who will be willing to provide training and support. If you still lack the confidence to accept clinical responsibility, you still have the right to decline. Your CCG pharmacist will assist you in making decisions about shared care. It would not normally be expected that a GP would decline to share prescribing on the basis of cost. The patient’s best interests are always paramount Date prepared: June 2016 Approved by (date approved): SWLStG Drug & Therapeutic Committee: June 2016 Mental Health Interface Prescribing Forum: June 2016 Review date: May 2019 This shared care prescribing guideline has been signed off by the following individuals on behalf of their respective organisations: Participating Clinical Commissioning Groups (CCG) Participating Hospital Trusts NHS Kingston CCG SWL & St. George’s Mental Health Trust Dr Anthony Hughes, GP on behalf of Medicines Dr M Zwi (Consultant Psychiatrist & DTC Deputy Management Committee Chair) Seema Buckley, Chief Pharmacist Dianne Adams (DTC secretary & Chief Pharmacist) NHS Richmond CCG Dr Stavroula Lees, lead GP for Mental health Emma Richmond, Head of Medicines Management NHS Merton CCG Dr Andrew Otley, Mental Health Lead Sedina Agama, Chief Pharmacist NHS Wandsworth Dr Gillian Ostrowsky, Associate Medical Director Nick Beavon, Chief Pharmacist NHS Sutton CCG Dr Chris Keers, Mental Health Lead Sarah Taylor, Chief Pharmacist Date approved: June 2016 Review date: May 2019 Version: 201705 2 1. CIRCUMSTANCES WHEN SHARED CARE IS APPROPRIATE Prescribing responsibility will only be transferred when the consultant and the GP are in agreement that the patient’s condition is stable or predictable.

CLINICAL INFORMATION Indication(s): Sleep onset insomnia and delayed sleep phase syndrome in children and adolescents (4-18years) and persistent sleep disorders in school-age children with neurodevelopmental disabilities. These indications are unlicensed but Circadin® is approved for use in SWL for these indications. Circadin® is licensed for use in those over 55 years of age for short term use with a primary diagnosis of insomnia. It is not approved for this indication in SWL. Place in Therapy: Second-line where non-pharmacological strategies have failed and underlying physical causes are managed. Treatment should be initiated by or under the supervision of a specialist Consultant and transferred to GP for prescribing after 3 months. Therapeutic summary: Melatonin is a naturally occurring hormone produced by the pineal gland in the brain. It is involved in coordinating the body's sleep-wake cycle and helping to regulate sleep. Special warning and precautions for use: Circadin® contains lactose. Patients with rare hereditary problems of galactose intolerance, the LAPP lactase deficiency or glucose-galactose malabsorption should not take this medicine. If the child wakes during the night, an extra dose of melatonin should not be given. Dose & route of administration: Prescribe licensed Melatonin (Circadin®) MR tablets 2 mg, first line, if clinically appropriate. Initiate at 2mg 1-2 hours before bedtime. Swallow tablet whole with plenty of water. Increase dosage according to response. Dose can be increased to 46mg daily after 1-2 weeks. Maximum BNFC dose 10mg Circadin® may be crushed to give an immediate-release profile.(see practical issues below) Duration of treatment should be determined on an individual basis. Treatment should be discontinued every 6 months to assess if it is still beneficial. GPs should prescribe only 28 days at a time with a review date of every 6 months. GPs may contact the professional initially recommending the prescription or Medicines Information for advice and support to undertake this review. Duration of treatment: Summary of adverse effects: (See Melatonin [Circadin®] Summary of Product Characteristics (SPC) for full list) Date approved: June 2016 Review date: May 2019 Version: 201705 Adverse effect Frequency Management Headaches Uncommon (more than 1 in 1,000 to less than 1 in 100 people might get these) Simple analgesia (e.g. paracetamol). Refer back to psychiatric team if persistent or troublesome. Abnormal dreams Uncommon Nausea Uncommon Dizziness Uncommon No management concerns. Offer reassurance that memory of dreams has improved. Usually transient. Try taking melatonin with or after food. Try not to change posture too quickly. Refer back to psychiatric team if persistent or troublesome. Leukopenia Rare (more than about 1 in 10,000 to less than 1 in 1000 people might get these) Stop medicine refer back to psychiatrist. No routine full blood count is recommended. 5 Monitoring Requirements: Clinically relevant drug interactions: (See Summary of Product Characteristics (SmPC) for a full list) 1. Under shared care Psychiatrists should monitor continued positive impact on sleep and review every 6 months by discontinuing the medicine to assess continued benefit. 2. Monitor weight and standard monitoring of growth and sexual development (this has been seen in animals but not in human use of melatonin). 3. Although leukopenia is a known (rare) side effect, regular FBCs are not specifically required. 1. Increased sedative effect when given with antipsychotics, other hypnotics and sedating antihistamines 2. Avoid combination with fluvoxamine as melatonin levels can be increased due to enzyme inhibition. 3. Cautious combination of cimetidine, oestrogens (eg contraception) due to potential to increase melatonin levels. 4. Co –administration of CY1A2 inducers such as Carbamazepine and rifampicin may give rise to reduced plasma concentrations of melatonin. 5. Co administration with CY1A2 inhibitor such as quinolones may give rise to increased melatonin levels. Be aware that that excessive drowsiness and related side effects may occur with concurrent use with quinolones. Practical issues: Key references: 1. Clinicians concerned over the possibility of sleep latency when prescribing the prolonged release tablets may advise patients to halve (preferably using a tablet crusher) and swallow both halves or crush the tablets. 2. Refer to the local specials guideline. 3. Note that crushing would no longer render it a modified-release preparation; careful halving may preserve some of the modified-release characteristics. 4. There is no stability data for crushed tablets so the powder would need to be administered immediately. Mix the crushed tablets with cold food or drinks to aid ingestion. There is no information for enteral administration. 5. If Circadin® is not appropriate for the following reasons (patient unable to tolerate it, swallowing difficulties) an unlicensed preparation may be used. 6. Prescribing unlicensed melatonin requires careful consideration by the psychiatrist and discussion with the parents or carer. Unlicensed formulations of melatonin may only be prescribed after SWLStG Drug and therapeutics approval on an individual basis. Unlicensed formulations must be supplied by a Hospital Pharmacy. 1.

The medicine contains a synthetic version of melatonin. In the UK, “Circadin,” a prolonged-release product licensed for use in people over 55, is now available. The MHRA has advised that this product be used wherever it meets the clinical need of the patient, even where that patient is outside the terms if its licence (e.g. in children). If this product does not meet the clinical need (e.g. prolonged release is not suitable, swallowing difficulties or the patient cannot tolerate the prolonged release and crushing Circadin is not successful), an unlicensed preparation may be used. Where this applies, the psychiatrist will have given careful consideration to prescribing it, and will have discussed the implications fully with the family. Indication Melatonin (Circadin) is on the formulary for the (unlicensed) treatment of persistent sleep disorders in school-age children (4-18 years) with neurodevelopmental disabilities. Sleep problems are common in this group. Where good “sleep hygiene” methods fail, medication may be considered. The regular hypnotic medicines can cause adverse reactions and lead to tolerance & dependence, and so melatonin is being used. Melatonin is licensed in the UK for the treatment of a diagnosis of primary insomnia in the over 55s for 13 weeks. Dosage and prescribing The dosage of melatonin will be established by the psychiatrist and will be within the range 2mg to a maximum of 10mg per day. It should be taken as a single dose, 30-120 minutes before sleep time. The medicine is usually swallowed whole, with a drink of water. If the child wakes during the night, an extra dose of melatonin should not be given. Crush if there are concerns over sleep Circadin MR 2mg latency or swallowing difficulties. Mix 1st line tablets with cool food stuffs e.g. yoghurt or porridge. Melatonin 3mg tablets Only use if patient cannot tolerate (Bio-melatonin) Circadin. 2nd line Melatonin 5mg/5ml oral solution Date approved: June 2016 Review date: May 2019 Version: 201705 9 Side effects (see BNF or SmPC for full info) The most common problem with melatonin is that it simply does not improve the child’s sleeping pattern. Side effects are fairly uncommon, but may include headache, fatigue, and dizziness. Other rarer side effects have included restlessness, increased heart rate, itching & nausea. Based on its physiological effects in animals there is a theoretical potential for melatonin to delay puberty, but this has not been reported in humans. Drug interactions (see BNF or SmPC for full info) Be cautious with sedating & antihypertensive medicines. Enzyme inhibitors & inducers may cause clinically significant changes in melatonin serum levels (e.g. ritonavir and carbamazepine). Monitoring & review The child should be monitored for the effect of melatonin on their sleep and for any of the potential side effects as described above. In addition, standard monitoring of growth and sexual development is recommended (check height, weight, pubertal development is progressing as expected). Those patients under the care of South West London & St Georges NHS Trust will have this review done by their specialist. Where the GP has a patient taking melatonin not being seen by a specialist, they should stop the melatonin abruptly every 6-12 months to assess the need for continued supply using a sleep chart for two weeks. GPs may contact the professional initially recommending the prescription or Medicines Information (number below) for advice and support to undertake this review. Melatonin has an elimination half-life of up to 50mins. Stopping a prescription for melatonin is not expected to cause withdrawal effects, apart from a possible worsening in sleep pattern if there is continued benefit. Source of supply South West London & St George’s formulary encourages its clinicians to prescribe unlicensed formulations on Hospital only prescriptions. Circadin may be prescribed on FP10 and transferred to GPs as part of shared care.

Find it by going to the Trust website, information for patients: www.swlstg-tr.nhs.uk or typing: www.choiceandmedication.org/swlstg-tr/ Insomnia is a sleep disturbance causing children to have trouble falling asleep or staying asleep at night or waking up too early. The insomnia arises when there is a feeling that the sleep does not have its restorative function and it affects the daytime function of the child. Long-term insomnia occurs three times a week for a month or longer and may be caused by factors for which your child may have been prescribed melatonin (eg, depression, anxiety, pain, medical problems). However, there may be no obvious reason at all. What is unlicensed melatonin and why should it be switched to the licensed branded UK product? Until recently melatonin was only available when manufactured or imported for specific children. A licensed UK approved product called Circadin® modified release 2mg tablets is now available. The Medicines and Healthcare products Regulatory authority advise professionals in the UK that where a UK approved product exists to treat an indication it must be used in preference for those that are imported or made individually for patients. This advice is to reduce the risk of harm to a patient from their medicines. Imported and individually manufactured products carry a greater risk of their use due to the less stringent controls and assessment of their production in comparison to UK approved products. Imported or individually manufactured products can be 100 times the cost of UK approved products and thus, do not provide value for money for the NHS and its users in most cases. Can melatonin products be switched easily? Yes. There is lots of experience that shows us that patients do not show any signs of withdrawal when melatonin is stopped or switched from one product to another. There have been some concerns that after switching from immediate release melatonin to the UK approved modified release melatonin: it may take longer for the onset of sleep. In most that has not occurred and the UK approved tablets may be crushed if needed. What review does melatonin require? There are no specific physical monitoring requirements for melatonin. The causes of insomnia can be complex and change over time. Stopping the melatonin for a two week period every 6-12 months is a good idea to ensure the medicine is still needed. A sleep diary and questionnaire available on the Mental Health Trust’s website is a good way of monitoring this. Complete the diary for at least a week before and after stopping melatonin to get a good view of the sleep pattern.
