History
Benzodiazepines when introduced in 1961 were widely believed to be safe drugs but as the decades went by increased awareness of adverse effects connected to their long-term use became known. There was initially widespread public approval but this was followed by widespread public disapproval and recommendations for more restrictive medical guidelines followed. Concerns regarding the long-term effects of benzodiazepines have been raised since 1980. These concerns are still not fully answered. A review in 2006 of the literature on use of benzodiazepine and nonbenzodiazepine hypnotics concluded that more research is needed to evaluate the long-term effects of hypnotic drugs. The majority of the problems of benzodiazepines are related to their long-term use rather than their short-term use. There is growing evidence of the harm of long-term use of benzodiazepines, especially at higher doses. In 2007 the Department of Health recommended that individuals on long-term benzodiazepines are monitored at least every 3 months and also recommends against long-term substitution therapy in benzodiazepine drug misusers due to a lack of evidence base for effectiveness and due to the risks of long-term use. The long-term effects of benzodiazepines are very similar to the long-term effects of alcohol (apart from organ toxicity) and other sedative-hypnotics. Withdrawal effects and dependence are almost identical. A report in 1987 by the Royal College of Psychiatrists in Great Britain reported that any benefits of long-term use of benzodiazepines are likely to be far outweighed by the risks of long-term use. Despite this benzodiazepines are still widely prescribed. The socioeconomic costs of the continued widespread prescribing of benzodiazepines is high.

Famous quotes containing the word history:
“History is the present. That’s why every generation writes it anew. But what most people think of as history is its end product, myth.”
—E.L. (Edgar Lawrence)
“The history of all hitherto existing society is the history of class struggles.”
—Karl Marx (1818–1883)
“I believe that in the history of art and of thought there has always been at every living moment of culture a “will to renewal.” This is not the prerogative of the last decade only. All history is nothing but a succession of “crises”Mof rupture, repudiation and resistance.... When there is no “crisis,” there is stagnation, petrification and death. All thought, all art is aggressive.”
—Eugène Ionesco (b. 1912)
