If the dose is rapidly decreased withdrawal may occur. Use during pregnancy or breastfeeding is not recommended. Temazepam is a short-acting benzodiazepine and hypnotic. It works by affecting GABA within the brain.Temazepam was patented in 1962 and came into medical use in 1969. It is available as a generic medication. In 2019, it was the 214th most commonly prescribed medication in the United States, with more than 2 million prescriptions. Medical uses
In sleep laboratory studies, temazepam significantly decreased the number of nightly awakenings, but has the drawback of distorting the normal sleep pattern. It is officially indicated for severe insomnia and other severe or disabling sleep disorders. The prescribing guidelines in the UK limit the prescribing of hypnotics to two to four weeks due to concerns of tolerance and dependence.The American Academy of Sleep Medicines 2017 clinical practice guidelines recommended the use of temazepam in the treatment of sleep-onset and sleep-maintenance insomnia. It rated the recommendation as weak, the quality of evidence as moderate, and concluded that the potential benefits outweighed the potential harms. The guidelines found that temazepam at a dose of 15 mg reduces sleep latency by 37 minutes (95% CI 21 to 53 minutes), increases total sleep time by 99 minutes (95% CI 63 to 135 minutes), and provides a small improvement to sleep quality.
It cites another study that "found that the odds ratio for finding results favorable to industry in industry-sponsored trials was 3.6 times as high as in non–industry-sponsored studies". Issues discussed regarding industry-sponsored studies include: comparison of a drug to a placebo, but not to an alternative treatment; unpublished studies with unfavorable outcomes; and trials organized around a placebo baseline followed by drug treatment, but not counterbalanced with parallel-placebo-controlled studies. Quoting a 1979 report that too little research into hypnotics was independent of the drug manufacturers, the authors conclude, "the public desperately needs an equipoised assessment of hypnotic benefits and risks" and the NIH and VA should provide leadership to that end.
