Introduction to Benzodiazepines What are Benzodiazepines? Benzodiazepines are a family of depressant or sedative drugs, also known as minor tranquillisers Originally developed by the pharmaceutical company Roche as a safer alternative to Barbiturates Chlordiazepoxide (Librium) was first prescribed in the UK in 1960 Diazepam (Valium) first prescribed in 1963 Benzodiazepines and the brain Act on an inhibitory neuro-transmitter gamma amino butyric acid (GABA) GABA regulates and inhibits the release of other neuro transmitters such as noradrenaline, dopamine and serotonin Without GABA our CNS would be effectively unregulated and heart rate and body temperature etc would increase uncontrollably Over time, GABA rely on Benzodiazepines for stimulation – without Benzos, GABA become inactive Benzodiazepine effects All benzodiazepine drugs have the same 5 primary effects in varying degrees Hypnotic Amnesic Anticonvulsant Anxiolytic Tends to cause sleepiness Memory disruption Reduces anxiety Reduces likelihood of Seizures Muscle Relaxant Reduces muscle tension and pain Why are they prescribed? Most commonly prescribed for stress and anxiety To help with short term sleep problems Sometimes prescribed for sporting injuries because of their muscle relaxant qualities Prescribed as an anti-convulsant for epilepsy For alcohol and GHB/GBL withdrawal Generic and brand names Diazepam – Valium Chlordiazepoxide – Librium Temazepam - Restoril Nitrazepam – Mogadon Lorazepam – Atavan Flunitrazepam – Rohypnol Clonazepam – Klonopin Alprazolam – Xanax Oxazepam – Oxazepam genus Some street names Vallies, Blues, Diazies, Mother’s little helper, Downers, Temazies, Moggies, Bennies, Jellies, Eggs, Benzos, Benzies, Tranx, Roofies...etc. Reasons for misuse/illicit use To help sleep To cope with stress To get ‘high’ Social reasons To help with the comedown from other drugs In place of other drugs such as heroin To increase the effect of other drugs Curiosity Perception that they’re safer than other drugs Source: Royal college of Psychiatry available at: http://bjp.rcpsych.org/content/205/5/407 How are they taken? Usually swallowed in tablet form Oral liquids Tablets are sometimes crushed, dissolved in water and injected Some now available in sublingual form Injectable liquids – mostly in surgical settings Side effects Drowsiness Confusion Dizziness Blurred Vision Lack of coordination Memory loss Constipation Dry mouth Difficulty breathing Depression Paradoxical stimulant effects Risks Overdose Tolerance Dependency/withdrawal Exploitation Assault STI’s Accidents Injecting related harms (DVT’s, vein damage, abscesses etc.) Coma and death Pregnancy and breastfeeding Benzodiazepines should be avoided if possible during pregnancy. There is a small risk of physical problems in the developing baby, such as: Cleft palate Urinary tract abnormalities Heart abnormalities Stomach abnormalities Dyslexia (difficulty reading and writing) Dyspraxia (problems with co-ordination and movement) Autism Attention deficit hyperactivity disorder (ADHD) Ref:http://www.mind.org.uk/information-support/drugs-and-treatments/sleeping-pills-and-minor-tranquillisers/aboutbenzodiazepines/#.WAXcFeArLIU Pregnancy and breastfeeding If taken at the end of pregnancy, benzodiazepines can cause the following problems in new-born babies: Drowsiness Floppy muscles Breathing problems Low body temperature Withdrawal symptoms including abnormal sleeping patterns, high-pitched crying, tremors, vomiting and diarrhoea Benzodiazepines are present in breast milk, and may build up in the baby’s body and cause side effects Ref:http://www.mind.org.uk/information-support/drugs-and-treatments/sleeping-pills-and-minor-tranquillisers/aboutbenzodiazepines/#.WAXcFeArLIU Tolerance and Withdrawal Tolerance can develop quickly (within two weeks) – higher doses required to get same effect Withdrawal symptoms include; Increased anxiety Sweats and shakes Hyper sensitivity Muscle aches, joint pain Headaches Seizures, coma and death Never tell a dependant user to stop using Detoxification Benzodiazepine use should not be stopped abruptly A process of ‘tapering’ where doses are reduced over time Typically, a reduction of 10% every 1 to 2 weeks down to 20% of original dose, then 5% every 2-4 weeks This process takes months rather than weeks and for some it can take years. Each detox is individual Ref: Benzodiazepine Withdrawal: What to Expect - How to Taper – How to Cope. www.choosehelp.co.uk Poly drug use 9 out of 10 deaths where Benzodiazepines are indicated, include another substance* Particularly dangerous when taken in combination with other respiratory depressants such as alcohol, heroin, methadone and GBL *Office of National Statistics ‘Deaths Related to Drug Poisoning in England and Wales’ 2015 Some Stats 3,674 drug related deaths reported in 2015* 366 deaths involving benzodiazepines in England and Wales in 2015 (highest ever reported)* Diazepam (Valium) accounted for 252 of these* 1 in 5 homeless people who reported drug use reported Benzodiazepine use in the last month** *Office of national statistics 2016. ** Homelesslink 2015 Some stats Of homeless people who reported drug use in the last month… 18% men reported Benzo use in the last month 24% women reported Benzo use in the last month Over 25% of people aged 26-45 reported Benzo use in the last month 22% rough sleepers reported Benzo use in the last month 33% sofa surfing or squatting reported Benzo use in the last month Source: Homeless link ‘Homelessness in numbers’ http://www.homeless.org.uk/facts/homelessness-in-numbers/health-needsaudit-explore-data Alternative drugs/therapies Propranolol - Beta blocker Anti depressants – e.g. Citalopram Alternative therapies – Acupuncture Relaxation and meditation Psychosocial interventions – e.g. CBT Mutual aid (NA, SMART recovery) Harm minimisation Avoid respiratory depressants such as alcohol, heroin, methadone, GHB/GBL, as these interact increasing sedation and risk of fatal overdose Avoid mixing benzos (they can react with each other) Avoid using alone Refer injectors to needle exchange services Ask clients about benzos specifically when assessing The Law Benzodiazepines are controlled under the Misuse of Drugs Act 1971 and are categorised as Class C Unauthorised possession (i.e. without a prescription) could result in a 2 year prison sentence and an unlimited fine Supplying, which includes giving Benzodiazepines to friends, could mean up to 14 years in prison and an unlimited fine Questions and discussion References and links Benzodiazepine Withdrawal: What to Expect - How to Taper – How to Cope.
