Summary
Clobazam is a unique 1,5-benzodiazepine with preferential α2 subunit binding, resulting in potentially less sedation than classic 1,4-benzodiazepines. FDA-approved for Lennox-Gastaut syndrome; used off-label for anxiety and other seizure types in some countries. The long-acting active metabolite N-desmethylclobazam significantly contributes to effects and extends duration.

Based on reports from:
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

Acute tolerance: develops within a single session — the reset numbers above apply after sustained heavy use, not after one binge. Within-session tachyphylaxis usually resets largely overnight.
Tolerance to hypnotic/anxiolytic effects tends to develop over weeks of daily use and decays slowly over weeks after cessation; seizure‑protective effects may persist variably. Data are drawn from class‑level evidence and clinical experience; individual variability is high.

Clobazam represents the safest benzodiazepine by a HUGE margin. The reason being that 100% occupancy of the GABA receptor site it binds to does not lead to one passing out, forgetting what one is doing or doing crazy/stupid/illegal stuff - just just LIE DOWN.
