    Summary TheDrug.Wiki Erowid TripSit

    Chlordiazepoxide was the first benzodiazepine synthesized and is primarily prescribed for anxiety disorders and acute alcohol withdrawal. It has a long half-life and produces long-lasting active metabolites, making it useful for tapering but inappropriate for elderly patients due to accumulation risk. Abrupt discontinuation after prolonged use can cause life-threatening withdrawal including seizures.

    Tolerance

    Build-up develops over 1–4 weeks of daily use; hypnotic tolerance faster than anxiolytic tolerance
    Reset weeks to months depending on half-life and duration of use; taper recommended

    Tolerance Decay

    Full tolerance 14d Half tolerance 7d Baseline ~42d

    Benzodiazepine tolerance builds to sedative/anxiolytic effects within days to weeks of regular use and decays slowly over weeks after cessation. Cross‑tolerance within GABA-A positive modulators is substantial but incomplete; individual variability is large. Data derived from clinical guidance and community reports; figures are illustrative, not prescriptive.
