3 MANAGEMENT AND DETOXIFICATION FOR GHB AND GBL GUIDELINES: PHA61: AUG 2019
1. Introduction
These guidelines have been produced in response to changes in drug usage amongst the clients who present for assessment and treatment within substance misuse services.
Camden and Islington NHS Foundation Trust has now established a specialist “party drug” clinic and all SMS have noticed an increase in clients presenting to services who are using gamma-hydroxybutyrate (GHB) and gamma-butaryl lactone (GBL).
2. Aims and objectives
The main aim of this guidance is to provide clear guidance about the withdrawal effects of GHB and GBL and their management.
To provide guidance to clinicians who are planning reduction plans and the medical detoxification for GHB and GBL.
To provide guidance on administering medication and monitoring of clients undergoing a detox from GHB and GBL.
To provide information about the potential dangers of clients suddenly stopping GHB and GBL.
3. Scope of the policy
This policy will be mostly applicable to substance misuse services which are provided by the Trust i.e. in Camden, Islington, and Kingston.
It may also be relevant to other services within Camden and Islington NHS Foundation Trust as clients using GHB and GBL may also present to other services. It would be recommended that detoxifications for GHB and GBL are carried out in discussion with specialist substance misuse services.
4. Background Information
Gamma butyrolactone (GBL) and 1,4-butanediol (1,4-BD) are precursors of
Gamma-hydroxy butyric acid (GHB). GBL and / or 1,4-BD are quickly converted
to GHB when they are ingested.
GHB and GBL can cause feeling of euphoria, reduce inhibitions and cause
sleepiness. The effects start about 10 minutes to an hour and can last up to 7
hours.
4 MANAGEMENT AND DETOXIFICATION FOR GHB AND GBL GUIDELINES: PHA61: AUG 2019
GHB, GBL and 1,4-BD are clear, odourless, oily liquids with a salty taste that
resembles stale water or burnt plastic (1). They are sold in liquid form in small
bottles. GHB can also be found in powder form (2) e.g. capsules or tablets as it
can form salts. These are usually dissolved in water or mixed with sweetened
drinks to hide their salty taste (1,2).
In 2003, GHB was classified as a Class C drug under the Misuse of Drugs Act
1971. It was then found that users were switching to GBL and 1,4-BD and so in
2009, GBL and 1,4-BD were also classified as Class C drugs under the Misuse of
Drugs Act 1971. It is against the law to possess them or sell them for human
consumption.
5. Licensed Usage of GHB, GBL and 1,4-BD
GHB is licensed in Europe as an anaesthetic agent. In the UK is in authorized
medicine, sodium oxybate for the treatment of narcolepsy with cataplexy (under
specialist supervision).
GBL and 1,4-BD also have legal uses and are available to licensed buyers.
They are used in solvents such as paint stripper, nail varnish removal and stain
removers.
6. Effects of GHB, GBL and 1,4-BD
GBL and 1,4-BD are inactive and are metabolised into GHB shortly after entering the body.
GHB occurs naturally in the central nervous system. It is metabolised in the body into GABA which acts on the GABAa receptor causing similar effects to benzodiazepines.
GHB and GBL have euphoric effects and can lead to increased confidence and reduced inhibition at low levels. At higher dosages they can cause sedation. The dose response curve is steep and so users can experience toxicity – leading to nystagmus, aggression, urinary incontinence and nausea.
Users of GHB, GBL and 1,4-BD use a pipette to measure out small doses.
Effects include the following:
Euphoria
Decreased inhibitions
Reduced anxiety
Loss of motor control
Emotional warmth
Increased libido
5 MANAGEMENT AND DETOXIFICATION FOR GHB AND GBL GUIDELINES: PHA61: AUG 2019
Sleepiness
Confusion / disorientation
Loss of coordination and balance
Reduced consciousness
Memory problems
Respiratory depression
Overdose – headache; nausea and vomiting; hallucinations; seizures
Loss of consciousness, coma and even death
7. Withdrawal Symptoms
When GHB and GBL usage increases the frequency of dosing becomes very
regular with users having to use every few hours. GHB users can develop
physiological dependency when they are using 1-2 mls of GHB/GBL every 1-2
hours; this includes waking during the night to take further doses.
It is estimated that users can develop dependency after using x3-4 per day for 2-
3 months (2). Withdrawal from GHB can last around 9 days (3).
Stopping GHB leads to a rapid onset of withdrawal symptoms which are similar
to the withdrawal effects of alcohol or benzodiazepines.
Withdrawal symptoms are as follows:
Tachycardia
Insomnia
Anxiety / restlessness
Confusion
Delirium
Nausea
Vomiting
Tremor
Hallucinations
Hypertension
Diaphoresis
Less common symptoms may include – seizures, rhabdomyolysis and possibly
death.
GHB withdrawal is a medical emergency.
6 MANAGEMENT AND DETOXIFICATION FOR GHB AND GBL GUIDELINES: PHA61: AUG 2019
8. Management of GHB and GBL Withdrawal – principles of gradual reduction
and detoxifications
As stated earlier withdrawal is a medical emergency and as such must be managed very carefully. It is advised to have a clear acute pathway for each particular substance misuse service to their local general hospital. There should have been liaison with the relevant hospital specialists, in particular the AED and anaesthetic departments before detoxifications are agreed. If problems should arise during the detox the client will need to go urgently to hospital and they should be issued with the Accident and Emergency letter (Appendix 4) and the Information on GHB / GBL for professionals (Appendix 5).
The scope of this guidance is for planned gradual reductions and / or planned community detoxification of clients with GHB / GBL dependency. The treatment protocol is for clients who are presenting in the absence of delirium.
It should be noted that if clients are not suitable for gradual reduction plans or community detoxifications they may need to referred for in-patient detox and rehabilitation – each service should follow their own policies and procedures for Tier 4 applications.
It may be possible for a client to follow a gradual reduction plan. Clients should be advised to stay on a consistent dose that they can tolerate for a few days, taking this dosage at the same time each hour. When clients have been able to do this for a few days they can then start to reduce the dosage by one-tenth of an ml each day, i.e. 2.0ml on Monday; then 1.9ml on Tuesday; then 1.8ml on Wednesday, etc. Once the client is down to 0.1ml they will be able to stop GBL without experiencing withdrawals symptoms. Clients should be informed that they may still feel uncomfortable and that it will take time for them to be able to adjust to life without GHB / GBL (see refer to Reduction Diary in Appendix 3).
Where delirium is present clients should be admitted to a general hospital as a matter of urgency and may need very high dosages of diazepam – up to 200mg in the first 24 hours. In essence where clients are using high dosages of GHB or GBL; are using GHB > 6 times every day; have a history of severe withdrawal symptoms are also dependent on other drugs (including alcohol or benzodiazepines) they would not be suitable for a community detox – please refer to indications for in-patient detoxes.
Where the client presents without delirium the following protocol can be used i.e. using diazepam and baclofen.

8 MANAGEMENT AND DETOXIFICATION FOR GHB AND GBL GUIDELINES: PHA61: AUG 2019
Detoxification Plan
The onset of withdrawal symptoms can range from 30 minutes to a few hours. It is
important to prevent the development of withdrawal delirium rather than waiting for
the full symptoms of withdrawal to start. Please note that the withdrawal medication
regimen below is a standard regimen and depending on the amount of GBH / GBL
the length of the regimen may be altered.
Prior to the commencement of a GHB / GBL detoxification clients should sign the
contract and consent form (Appendix 2). They should also be issued with the
information sheet for clients undergoing a GHB / GBL detox (Appendix 6).
Table 1 – GHB / GBL Withdrawal Medication Regimen
Day of Treatment Time of observation and treatment
(T1 is 1 hour after last time of usage; T2 is 2 hours after last time of usage; etc.)
1 T1 observations, diazepam 10-20mg (10mg standard dosage, 20mg if agitated)
T2 observations, diazepam 10-20mg, baclofen 10mg
T4 observations, diazepam 10mg PRN (if symptomatic)
Please issue diazepam 3x10mg to be taken PRN at T6, T8 and T14 (if symptomatic) and 2x10mg baclofen to be taken at T8 and T14
Observations (temperature, pulse, blood pressure, mental state examination, alcohol withdrawal scales) to be taken at T1, T2, T4.
Generally maximum dosage on Day 1 is diazepam 100mg and baclofen 30mg

There is no GHB / GBL withdrawal scale but as the withdrawals are similar to alcohol withdrawals in the early stages then the Clinical Institute Withdrawal Assessment for Alcohol Scale (CIWA-AR) can be used (please see Appendix 7).
In severe withdrawals urgent transfer to hospital will be necessary. However the following medications may be useful.
Table 2 – Adjunctive Medications
Diarrhoea Loperamide (4mg initially followed by 2mg after each loose stool [max 16mg daily])
Nausea and Vomiting Domperidone 10mg tablets, maximum 30mg in 24 hours
Pain Paracetamol 500mg-1g qds
10. Additional Support
It should be remembered that the above treatment is the pharmacological treatment for the withdrawal symptoms but as with all substance misuse treatment there is the need for psychosocial interventions.
As part of an individual’s treatment plan there will be psychosocial support in the form of motivational interviewing, the use of individual and group sessions, mutual aid organisations and relapse prevention work. Clients need to be made aware of the risk of decreased tolerance following a detoxification and a careful aftercare plan is critical. As part of the aftercare clients need to be made aware of relapse triggers and cues for relapse.
Referrals may also need to be made to other services to support with underlying or additional needs. Clients need to be informed that following GHB / GBL usage clients can experience insomnia, anxiety and loss of appetite for weeks to months following the detox.
11. Dissemination and implementation arrangements
This policy will be circulated to all team members working in Camden and Islington NHS Foundation Trust Substance Misuse Services. Dr Sarah Minot

Appendix 2 CONTRACT AND CONSENT FORM FOR MEDICALLY ASSISTED COMMUNITY GBL / GHB WITHDRAWAL
The following stipulations have been designed to help you in the next couple of weeks, so that you have the best chance of giving up GBL / GHB, as it is your wish.
The programme requires that you be abstinent from GBL / GHB, alcohol and non-prescribed drugs. Thus, while on the programme you must not consume or possess any alcohol or drugs other than those prescribed by the doctor. During this time you may be breathalysed and you may be requested to supply a urine sample for drug screening. If either of these proves positive, you will not be able to continue with the programme. You may be able to join the programme again at a later date, but you should discuss first with your keyworker whether this is still the most appropriate option for you.
In order to get the maximum benefit from the programme, you will need to give it your full priority. If you are working, it is strongly suggested that you arrange to take time off for an extended period, to give yourself space for the detox and recovery.
You will be expected to stay the full duration of the sessions, for the whole programme, and to take all medication as prescribed by the doctor and detox nurse. Should you miss a session for whatever reason, you will not be able to continue with the programme.
Aggressive, violent, abusive, racist or sexist language or behaviour can not be tolerated. If you demonstrate any of these you will be asked to leave the programme.

Appendix 5 INFORMATION ON GHB / GBL FOR PROFESSIONALS
Known as ‘G’ it is a clear, odourless, oily liquid which is sold in liquid form or GHB can found in powder form which is dissolved in water or mixed with drinks to hide their salty taste. Users will then take small amounts – 1-2 mls using a pipette in increasing frequently as dependency increases. Users can have to use every 1-2 hours throughout the day and night. Dependency on GHB / GBL can develop after daily usage for several months. Stopping GHB leads to a very rapid onset of withdrawal symptoms which are similar to the withdrawals effects of alcohol and / or benzodiazepines. GHB / GBL withdrawals are a very serious and potential fatal condition and needs to be treated rapid and often involves admission to Intensive Care Units. The withdrawal symptoms may include: Tachycardia Insomnia Anxiety / restlessness Confusion Delirium Nausea Vomiting Tremor Hallucinations Hypertension Diaphoresis Seizures Treatment of GHB / GBL withdrawals includes the use of high dosage benzodiazepines – about 100mg diazepam in the first 24 hours. Research has also shown that baclofen may be helpful in the management of withdrawal symptoms; further studies are continuing to fully explore the benefits of baclofen. Generally baclofen 10mg tds is given to patients and this dosage is gradually reduced after the few 5 days.
17 MANAGEMENT AND DETOXIFICATION FOR GHB AND GBL GUIDELINES: PHA61: AUG 2019
Appendix 6 INFORMATION ON GHB / GBL DETOXIFICATION FOR CLIENTS You have made the very important decision to stop using GHB / GBL, this programme has been put together to give you the best possible chance to achieve this goal. This leaflet will give you essential information about GHB / GBL detoxification and inform you of what you can expect from us and what we expect from you. Please read it carefully and don’t be afraid to ask questions Withdrawal Symptoms Withdrawing from GHB / GBL is often accompanied by some unpleasant experiences, such as shaking, anxiety, feeling jumpy and nervous, feeling irritable, sweating, nausea, racing thoughts and insomnia. These are withdrawal symptoms and with medication the worst aspects can be relieved. However, GHB / GBL intoxication places a heavy burden on the body and consequently you should expect to experience some discomfort. On this programme, you will be prescribed a medication called diazepam and baclofen. This is usually quite safe, but can make people drowsy. Thus, during detoxification it is recommended that you refrain from driving, operating machinery or undertaking any tasks that require being alert. In addition, the medication is not safe when taken together with alcohol and thus if you resume drinking you must stop taking it at once. For some people withdrawal symptoms are more severe, including for example:
Confusion
Disorientation
Blacking out
Hallucinations
Fits
If you do experience any severe symptoms you will need to seek immediate assistance at the nearest Accident & Emergency Department.
What you can expect from us When you start on this programme, you will be assessed by a doctor, who will prescribe the medication. A nurse will then monitor withdrawal closely, helping you to plan the week and to cope with these symptoms. What we expect from you The following stipulations have been designed to help you in the next couple of weeks, so that you have the best chance of giving up alcohol, as it is your wish.
The programme requires that you be abstinent from GHB / GBL, alcohol and non-prescribed drugs. Thus, while on the programme you must not consume or possess any GHB / GBL, alcohol or drugs other than those prescribed by the doctor.
You will be asked to be breathalysed and you may be requested to supply a urine sample for drug screening. If the breath alcohol reading is positive, you will not be able to continue with the programme. If your urine is positive for drug(s) that you have not told us about, the detoxification may need to stop. You may be able to join the programme again at a later date, but you should discuss first with your key worker whether this is still the most appropriate option for you.
18 MANAGEMENT AND DETOXIFICATION FOR GHB AND GBL GUIDELINES: PHA61: AUG 2019
In order to get the maximum benefit from the programme, you will need to give it your full priority. If you are working, it is strongly suggested that you arrange to take time off for an extended period, to give yourself space for the detox and recovery.
You will be expected to stay the full duration of the sessions, for the whole programme, and to take all medication as prescribed by the doctor and detox nurse. Should you miss a session for whatever reason, you will not be able to continue with the programme.
Aggressive, violent, abusive racist or sexist language or behaviour cannot be tolerated. If you demonstrate any of these you will be asked to leave the programme
Points to Remember Your Safety During detoxification you may experience forgetfulness, irritability and poor coordination: be careful, therefore, when cooking, boiling water and doing other tasks that require care. It would be helpful for you to arrange to have a responsible person around during this time, to help you with these practicalities. Your Environment
Try to arrange it so that your surroundings are as peaceful as possible. For this, it may be best to let those around you know that you will probably be feeling fragile for a few days. Also, it is advisable that you don’t keep alcohol in your home. In the early stages of recovery you will be vulnerable, so avoid situations where alcohol is consumed or openly available. Your Time Most people find that if they keep busy, it helps them not to dwell on negative feelings. Give the coming week some consideration: don’t leave things to chance. Your Diet Try to eat something even when you are not hungry. Eating little and often will help minimise craving. Drink plenty of fluids.
