Section 11 Prescribing for groups with special needs
Drug Abuse
Summary
Introduction Pregnant women For a full discussion of the effects of methadone on the foetus see Section 4: Physiology and pharmacology of methadone. The risks to the mother and baby that services can have some influence over are:
Interagency co-operation Where necessary interagency co-operation should help ensure that the mother receives the best possible care and treatment. The following liaison procedure has been suggested as good practice.92 However its potential for raising anxieties unnecessarily should be recognised. The aim should be for as normal a pregnancy and birth as possible, and in the absence of concern about the safety of the child or mother, it is often sufficient for the prescriber or drug service to liaise with the GP, community midwife and health visitor, and with the hospital. Procedure where there is concern The purpose of this meeting is to:
A second meeting of the same staff should be planned for 2 weeks before the expected date of delivery. The possibility of premature labour must be considered and the date of this meeting brought forward, if necessary. The purpose of this meeting is to:
Following the birth there should be a pre-discharge meeting with membership as above and including a paediatrician to:
The purpose of the review meeting at 3 months is:
Methadone treatment in pregnancy Pregnancy is a time when many women are able to make changes such as giving up drugs because of the added motivation of being pregnant. Where this is possible it should be encouraged and supported by the workers involved. However many women find that during pregnancy they experience an increase in:
Skilled, careful and non-judgmental assessment of the situation is therefore essential prior to a treatment plan being formulated. If detoxification is chosen it is important that contingency plans are made for the prevention and management of relapse following the birth. The optimal time to detox is the second 3-month period of the pregnancy. The normal maximum reduction in the daily dose in any week is 10mg. The final, slower part of a detox is often carried out (under close medical supervision) in the final 3 months of pregnancy without risk to the baby. However only a proportion of women will be able to achieve abstinence because of either relapse or obstetric complications. Short or long-term methadone maintenance will be the treatment chosen by most pregnant women.91 As what is best for the mother is best for the foetus the dose should be adequate to enable the mother to avoid illicit heroin use. Babies withdrawing from opiates Care of the withdrawing infant In the UK, if treatment is required, chlorpromazine is usually used with a regime such as the following:
The literature also includes withdrawal regimes using other non-opioid drugs such as phenobarbitone, clonidine and the benzodiazepine diazepam, opiate drugs such as camphorated opium tincture (Paregoric) and methadone. Breast-feeding Care of the parents of a withdrawing infant It is important for staff to deal with their feelings about a mother’s drug use separately from their care of her and the baby – especially if the mother requires extra help in learning to care for her child. Drug service staff can often be of assistance in the process of helping maternity staff understand the drug-related issues and their feelings towards drug-using mothers. The rationale for prescribing to the baby should be explained to the parents. It may be necessary to tell parents that they must never administer opiates to the child – even if it displays distress similar to withdrawal symptoms. If admission to a special care baby unit is required it is helpful for the parents to be introduced to the staff as soon as possible. Young people The Children Act 1989
This will usually be the line manager in the first instance and then social services. It is not possible for workers to argue that the drug user, not the child, is their client and that therefore they should do nothing, or that it is the responsibility of other workers to identify these issues. Because of this it is good practice for workers to explain to the client at the outset their responsibilities with regard to confidentiality and child protection. It is useful to explain to clients what ‘serious harm’ means as well as informing them of the factors that might cause concern regarding care of a child. However this must be done sensitively and the client must be reassured that ‘at risk’ is not synonymous with ‘in the care of a parent who is prescribed methadone’. Methadone treatment for young people
Parental consent to treatment will almost always be required. If a skilled assessment has ascertained that the young person is mature enough to be able to give informed consent to treatment, the Scarman ruling in the Victoria Gillick case would appear to make treatment without parental consent a legal option. In such cases the whole decision –making process needs to be very carefully documented. In-patient assessment and specialist consultant prescribing are strongly indicated if methadone treatment is considered for a young person. Clients with responsibility for young people If the client has responsibility for children the Children Act 1989 is clear that as far as the worker is concerned the needs of the child are paramount. If it appears that there are times when there are no suitable arrangements for the care of children who are at risk of serious physical, psychological or emotional harm or at risk through neglect, a skilled and full assessment should be carried out. The local authority has a responsibility to offer help and support to the parents or carers and child. This must be done sensitively and with the long-term aim of helping the family stay together where this is in the best interests of the child. It is important that people working with parents or carers understand the Children Act and have immediate access to supervision and specialist social work support if child care becomes an issue. People who have HIV In prescribing methadone for clients who have HIV it is important to:
Only prescribe drugs for the treatment of HIV-related illness as a last resort if the client refuses to see a specialist doctor. Prescribing treatment for symptomatic HIV is best done in conjunction with a specialist, as methadone interactions with drugs used in the treatment of HIV such as AZT, are not yet fully researched or understood. Drug users who have had a positive HIV test will have a variety of responses and needs. A positive test in itself may not change drug-using behaviour. Although for some it will lead to positive changes for others it may trigger a period of chaotic drug use. The process of adjusting to living with HIV may involve not only coming to terms with feelings of loss and grief but also a discovery of life or rediscovery of a purpose to live, in the knowledge that they cannot become uninfected. Treatment options are the same for opiate users, regardless of HIV status, and a full assessment needs to be carried out to weigh up the pros and cons of the available treatments. Some drug users who are living with HIV may avoid dealing with the many feelings they experience by using prescribed and illicit drugs in a dangerous and chaotic way. This can be exacerbated by the knowledge that as there are serious health consequences in being discharged from a methadone prescribing programme, termination of the prescription may be less likely, possibly leading to disruptive behaviour and refusal to comply with the prescribing contract. Minority ethnic groups It is incumbent upon services not only to have equal opportunities policies and to employ staff from ethnic backgrounds but also to offer culturally appropriate services to ethnic communities as a whole, and to the drug users within those communities. People who ‘use on top’ Clearly in order to be able to deal with additional drug use the worker must first be aware of it. This means either forming a therapeutic relationship with the client in which these issues can be discussed (which will normally mean that the threat of removal of prescribing on discovery of illicit drug use is not a useful part of the agreement) or having effective urine screening procedures which, as discussed in Section 10, is difficult and expensive. It is important to assess the scale, nature and motivation of illicit drug use before taking action. There is a world of difference between using heroin every other ‘giro day’ and using it on a daily basis, and frequently selling the methadone, and while the latter may require action the former may be enough of an improvement to continue with no change to the programme. People take heroin in addition to their methadone for a number of reasons which include:
If it is identified that illicit drug use is occurring and jeopardising the treatment aims appropriate strategies should be employed to reduce risk behaviour. Treatment options include increasing:
and:
People who ‘don’t get better’
Towards the end of an ‘opiate-using career’ these periods of abstinence usually become longer and the periods of relapse shorter. Demoralising the client by constantly admonishing their failures is unlikely to help them move forward or use help constructively. An approach which recognises where the client is, sets appropriate goals, and offers appropriate help will be more successful. People with mental health problems Rates of depression in opiate users have been found to be five times higher than in the general population.94 Careful history taking at initial assessment will pick up whether there is an increased likelihood of mental health problems and careful monitoring, particularly during detox, will detect the emergence of underlying mental health problems as the dose is reduced. Most people who are being treated for mental health problems can be treated concurrently with methadone for their drug dependence. Some disorders such as depression and anxiety are likely to be improved by the increased stability and access to professional help afforded by methadone prescribing. Some people use opiates as medication for paranoid or other psychotic ideas, and as such may become more ill as they stabilize or reduce their opiate intake. Inappropriate referrals People dependent on injection practice For those clients who find injecting a powerful ritual, stopping altogether can be as hard to achieve as abstinence from drug use itself. Services must recognise that clients who achieve abstinence from compulsive injecting will feel frustration and support should be offered accordingly. Reducing the harm associated with injecting may be helped by:
