Agitation observed during treatment with newer hypnotic drugs.

Side effects involving agitation, e.g., sleepwalking, anger, and panic, were observed in 10 insomniac patients treated with temazepam or triazolam but not other benzodiazepines. Each patient described these side effects as uncharacteristic. Milder agitation was observed in 2 cases. In 4 cases, these effects were doubted by the prescribing physician. This type of side effect has been only slowly recognized for other benzodiazepines and has not been much reported for these newer agents. Agitation observed during treatment with these agents may be related to their short elimination half-lives.
