Tolerance, Dependence and Withdrawal
A review of the literature found that long term use of benzodiazepines including triazolam is associated with drug tolerance, drug dependence, rebound insomnia and CNS related adverse effects. It recommended that benzodiazepine hypnotics are used at their lowest possible dose and for a short period of time. Non-pharmacological treatment options however, were found to have sustained improvements in sleep quality. The risk of withdrawal reactions and drug dependence is much higher with triazolam than with other benzodiazepines. Triazolam has a very high risk of dependency with chronic users often taking exceedingly high daily doses. Regular use of triazolam may cause a hypnotic drug dependence. Withdrawal symptoms typically appear when triazolam dosage is reduced or stopped altogether. Withdrawal symptoms including a worsening of insomnia (rebound insomnia) compared to baseline typically occurs after discontinuation of triazolam even after short term single nightly dose therapy.
Daytime withdrawal symptoms are commonly associated with triazolam. This is due to its very short half-life. After only 10 nights of triazolam use, patients report anxiety, become distressed, display weight loss, experience panics, and experience depression, feel unreal, and develop paranoia. These reactions occurred more commonly with triazolam than lormetazepam, which has an intermediate half-life. Thus the more short-acting a benzodiazepine hypnotic the more severe the daytime withdrawal symptoms. This phenomenon of day time withdrawal anxiety from nightly hypnotic use does not seem to be exclusive to triazolam but occurs with other hypnotic drugs although reactions are not as severe as those seen with triazolam.
Abrupt withdrawal after long-term use from therapeutic doses of triazolam may result in a severe benzodiazepine withdrawal syndrome. A psychotic state was reported in a patient, developing after abrupt withdrawal from triazolam and nitrazepam. The withdrawal symptoms included auditory hallucinations and visual cognitive disorder. Gradual and careful reduction of the dosage was recommended to prevent severe withdrawal syndromes from developing.

Famous quotes containing the words dependence and/or withdrawal:
“... dependence upon material possessions inevitably results in the destruction of human character.”
—Agnes E. Meyer (1887–1970)
“A separation situation is different for adults than it is for children. When we were very young children, a physical separation was interpreted as a violation of our inalienable rights....As we grew older, the withdrawal of love, whether that meant being misunderstood, mislabeled or slighted, became the separation situation we responded to.”
—Roger Gould (20th century)
