Benzodiazepine withdrawal effects.

J C Pecknold, D J McClure, D Fleuri

    Progress in Neuro-Psychopharmacology & Biological Psychiatry
    |January 1, 1982

    Summary

    Withdrawal from benzodiazepines like halazepam and oxazepam can cause symptoms, peaking in the first two weeks. Gradual tapering with a placebo reduces withdrawal severity compared to abrupt discontinuation.

    Area of Science:

    • Psychiatry
    • Pharmacology
    • Clinical Psychology

    Background:

    • Anxiety neurosis is commonly treated with benzodiazepines.
    • Understanding benzodiazepine withdrawal is crucial for patient management.
    • Halazepam and oxazepam are commonly prescribed anxiolytics.

    Purpose of the Study:

    • To evaluate withdrawal effects of halazepam and oxazepam.
    • To compare abrupt discontinuation versus placebo-assisted withdrawal.
    • To characterize the timeline and severity of benzodiazepine withdrawal symptoms.

    Main Methods:

    • Twenty-nine patients with anxiety neurosis were studied for eight weeks post-treatment.
    • Participants received either halazepam or oxazepam in a prior study.
    • Withdrawal protocols included abrupt cessation or a two-week placebo taper.

    Main Results:

    • No significant difference in withdrawal patterns between halazepam and oxazepam.
    • Withdrawal symptoms peaked between weeks 1 and 2, with potential rebound effects.
    • Placebo-assisted withdrawal resulted in significantly less severe symptoms than abrupt cessation.

    Conclusions:

    • Benzodiazepine withdrawal symptoms are common and can include rebound effects.
    • Gradual tapering with a placebo is a safer method for benzodiazepine discontinuation.
    • The duration of action of benzodiazepines did not significantly alter withdrawal patterns in this study.
