Chlordiazep oxide

Signs and symptoms of BZ withdrawal are similar to those of alcohol withdrawal, including muscle pain, anxiety, restlessness, confusion, irritability, hallucinations, delirium, seizures, and cardiovascular collapse. Withdrawal from short-acting BZs (e.g., oxazepam, lorazepani, alprazolam) has an onset within 12 to 24 hours of the last dose. Diazepam, chlordiazep-oxide, and clorazepate have elimination half-lives (or active metabolites with elimination half-lives) of 24 to greater than 100 hours. So, withdrawal may be delayed for several days after their discontinuation.
