IMPORTANT MESSAGE FROM PROFESSOR ASHTON
Professor Ashton would like to draw attention to the following points which are mentioned in the manual but not always heeded by doctors or patients:
It is worth pointing out to your prescriber that the withdrawal schedules provided in the manual are only intended as general guides. The rate of tapering should never be rigid but should be flexible and controlled by the patient, not the doctor, according to the patient's individual needs which are different in every case.
The decision to withdraw is also the patient's decision and should not be forced by the doctor.
Note that alcohol acts like benzodiazepines and should be used, if at all, in strict moderation as advised in this manual.
Antibiotics for some reason, sometimes seem to aggravate withdrawal symptoms. However, one class of antibiotics, the quinolones, actually displace benzodiazepines from their binding sites on GABA-receptors. These can precipitate acute withdrawal in people taking or tapering from benzodiazepines. It may be necessary to take antibiotics during benzodiazepine withdrawal but if possible the quinolones should be avoided. (There are at least six different quinolones - ask your doctor if in doubt).
C. H. Ashton, January 2007
These chapters were written by request in 1999 for readers in the USA concerned about the problems associated with long-term benzodiazepine use. Inquiries from Canada, Australia and the UK have suggested that the advice in the manual might be of help to a wider audience. Accordingly, some additions have now been made, particularly for readers in the UK.
A limited list of benzodiazepines that can be prescribed on the National Health Service was introduced in the UK in 1985. These include diazepam, chlordiazepoxide, lorazepam and oxazepam for anxiety; nitrazepam and temazepam for insomnia. Triazolam was originally on the list but was later withdrawn. Other sleeping pills now available on the NHS include the benzodiazepines loprazolam and lormetazepam and two drugs, zopiclone and zolpidem, which although not benzodiazepines, act in the same way and have the same adverse effects including dependence and withdrawal reactions. Information about benzodiazepines not included in the first US edition, and suggested withdrawal schedules for chlordiazepoxide, oxazepam and zopiclone have been added here.
Unfortunately, the benzodiazepine saga is far from over. Despite the fact that benzodiazepines are only recommended for short-term use, there are still about half a million long-term benzodiazepine users in the UK who have often been prescribed benzodiazepines for years. Many of these people have problems with adverse effects including dependence and withdrawal reactions, for which they receive little advice or support. The problem is even greater in countries (Greece, India, South America and others) where benzodiazepines are available over the counter. Because of widespread prescribing and easy availability, benzodiazepines have now, in addition, entered the "drug scene". They are taken illicitly in high doses by 90% of polydrug abusers world-wide, unleashing new and dangerous effects (AIDS, hepatitis, and risks to the next generation) which were undreamt of when they were introduced into medicine as a harmless panacea nearly 50 years ago.
I hope this booklet will provide information of value to benzodiazepine users unable to find advice elsewhere and perhaps raise awareness in the medical profession about the dangers of excessive or long-term benzodiazepine prescribing. The main credit for any use this monograph may be should go to Geraldine Burns in the USA, Rand M Bard in Canada, and Ray Nimmo and Carol Packer in the UK for their energy, enthusiasm and expertise in producing and distributing this booklet and making it available to people on the Internet throughout the world.
FOREWORD TO REVISED EDITION, AUGUST 2002
This edition contains some new material which I have added in response to requests and queries from readers in many countries including Europe, North America, Australia, New Zealand, South Africa and India. Additions include further information about withdrawal of antidepressant drugs, some advice for older or "elderly" people, and a mention of complementary, non-drug, techniques helpful in benzodiazepine withdrawal. There is also an epilogue outlining areas where further action about benzodiazepines - education, research and facilities for long-term users - is urgently needed. I am glad that this monograph has been helpful to people all over the world and am grateful for the many thanks I have received. I hope also that it will encourage professionals and others to undertake properly controlled trials aimed at improving the management of benzodiazepine withdrawal. This booklet is surely not the last word on the subject.
